WOW!!!!! 5 years later and your knowledge is still saving the day and only took me 7-8 videos of people who, I don’t know or can’t say what their talking about but if I listened to half of them I would have purchased an entire new pump but thought, DAM I only have 2 hours on this $375 rig and it just can’t be the pump but then I found your video and BINGO!!! Such an easy fix and will now know it until my dying day!!!! God bless you brother 🙏🙏🙏
For every single video like this one that gets straight to the point, and uses the proper part names, there are 8 or 9 others that are little more than blah blah blah, posted by guys who don't always know or use the correct lingo, either. They're oftentimes examples of how NOT to say or do things. Such is the price of having a platform like UA-cam that has no barriers to entry. So...thanks very much for your efforts here, Mr. Morgan.
I have a Homelite 2200psi gas pressure washer that stopped working. There were no leaks in the pump but there was very low pressure. I took the pump apart and unstuck the little piston with a few taps from a screwdriver handle just like this video says. Put it back together and it now works perfect with full pressure. Thanks, you saved me the price of a new pump!
UPDATE:1 year and still cranks within the first 2-3 pulls. Probably will buy another when this one finally does bite the dust ua-cam.com/users/postUgkx43QMbQqu67IZadu9ou8Sg1BdrunMRNqX . No issues at all. Very happy with it.UPDATE: After 6 months of use and over 70 uses I would still highly recommend this pressure washer. It does vibrate a decent amount but never had it “walk” like others have mentioned. No oil leaks, still seems to run like the day I bought it. Still cranks within 2-3 pulls every time. Very happy with my purchase!Have used it about a dozen times now. Plenty of power, cranks up on 1-2 pulls every time. My only complaint would be I wish it was a little taller to make it easier to walk with it (hits my ankles a lot) and that the two hose connections were a little further apart but it hasn’t caused me any issues. Seems to run a good 1-1/2-2 hrs on a full tank, overall a well built machine and definitely worth the money in my opinion.
Awesome! I wish I saw this a week ago, but better late than never. This needs to be number one in search results for power washer trouble shooting. Search result say to check this valve, but nowhere to explain how or why. All units seem to have this same assembly, a little attention here saves money and time! With this, you can buy rejects in yard sales and get em going to resell for $$$. Thank you Mr Morgan!
Thank you for the informative video. You saved me about $100.00. I was thinking about buying a new pump, but I fixed mine after watching your video. Much appreciated!!
Thank you sir. The Internet can seem like such a crappy place and then you search and find something like this video that explains my problem clearly and simply and allows me to fix something. Bravo.
Nice video. You are the only one who shows the second inside piston!!!! I checked my unloader but didn’t check that! Hopefully you will save me from buying a new pump!!
Hey Corey! Thanks very much for taking the time to put this video out there for the rest of us. The cutaway pump was outstanding and the total disassembly of the uploader is exactly what's missing from every other video I watched on this problem. Thanks again and take good care.
Wow everything on the net regarding unloaders they breeze past them and never explain in detail. Thank you so much you just solved a ten year old mystery for me regarding my old Honda pressure washer. Finally an unloader fully taken apart and simply explained!
Corey, the cut away and explanation helped me fix my PW. I would assume by all the comments it helped many others. My comment here can not truly show my appreciation. A huge thank you for an excellent video. I hope you made money on this video. I doubt that was your intention but, seriously would like to say thanks. " You the man Sir!".
Thanks for posting this video. It got me up and going. One other thing to mention, check the inlet water screen. Mine was completely clogged, so therefore it may have been part of my problem by not Letting enough water pressure into the pump...thanks again. Rob in SC
Here is some knowledge. The device you're displaying is an integrated unloader, with dual-bypass. The small bypass is used to unload the pump until a certain pressure is reached. This makes it easier to start the pump/engine assembly. The large bypass is used to unload the pump when a certain pressure is reached. This stops run-away pressure and dramatically reduces wear on the pump seals, when not spraying. However, if left in this state for any length of time, temperature and wear increase. Always stop the pump if you're not spraying for more than a minute or two. Also, the unloader is not to be used as variable pressure adjustment. That's what different orifice-size tips are for.
Abc Abc So if the unloader was turn for more pressure and used as a variable to reduce the pressure ,Which is incorrect from your statement ...How would I return the unloader 'to the correct position
Brother to the Creator this Channel or that video the next line job that was to the point no-nonsense great job man thank you and I hope you continue to do more everyday
Thanks Corey! It's people like you, creating excellent videos like this, that make UA-cam a valuable place to find answers! Perfect explanation! This is what I was hoping to find to help me troubleshoot the problem I'm having with the pressure washer I picked up at a local garage sale.
Same here - picked one up from a sale site for free - it was destroyed inside from broken bearings, seized up valves and so on. Now just awaiting a new bearing being delivered and can rebuild and test. 160 bar pressure washer for the cost of a new bearing (£2.50) 👍🏻
Amazingly informative video. I was shown how to fix the unloader before but with everything else if you don't do it you forget. Video refreshed my memory and also gave me more indepth explanation. Thank you
Thanks for the explanation Corey. For those of you that aren't aware you should never adjust your pressure using the unloader valve. To decrease/increase pressure change out your tips.
I don’t think he’s talking about changing it regularly to tailor the pressure for a particular job. He’s talking about setting it once so the pressure is correctly set for the engine power.
Thank you very much for taking the time and investment for making the cutaway of the pump and the dissasembly, you are a great human being and your effort and commitment will be rewarded with blessings, greetings from Chihuahua, Mex.
NOW THAT IS A HELPFUL VIDEO. I don't think you understand Corey what a relief it is to find a concise, brief and easy to follow self help video like yours among an ocean of prolific idiots. My hobby is dirt bikes and you best believe every banjo playing goober in the Appalachian Mountains that puts gas in an old motorcycle and it accidentally starts??!! That makes him a certified you tube master mechanic. Don't get me wrong-in the not too distant future- I WILL EVENTUALLY PERFORM OPEN HEART SURGERY using no more than 4 or 5 you tube self help videos.
Thank you very much for this. My pressure washer was driving me crazy not running right at full pressure and quitting every time you let off the trigger. This simple five minute fix fix all of my problems. Thanks again for the help. Great video.
I run a pressure washer 8 hours a day 5 days a week and use salt water in the machine ,i ended up putting a screw in sacraficial anode in a t piece befere the pump making things last a bit longer ,plus a bigger inline filter ,then a good quality turbo nozzle and make sure i have a good water supply but its still something that every oil change i pull the valve apart soak it in rust converter for a little bit and get the calcium build up off and any rust and put it back together ,with the vavle working correctly its a easy day ,and when its not working properly its a slow painfull day ,some times u can run a little rust converter thru and it comes good but too much rust converter for too long can damage things so good vidio , it helps to get your head around the unloader by having it cut away like u did cheers
Thanks yube77. I'm usually on a slow internet connections when I'm trying to follow a DIY video to fix something, so I try to keep my videos short and to the point.
My real problem then was no pressure but with water coming out. Then later, having enough pressure but the pump is not stopping even when the wand was released. Then I saw your video. That's really really, man.. Appreciate it.
Hi, thanks for making and sharing this video. I understand how my pressure washer works. It helps me in understanding the problem of my washer. With some tightening and loosening of parts, my washer works normally again!!! Thanks, really appreciate it!! from Philippines.
Thank you!! I “inherited” a GC160 Honda powerwasher and pulled it out to try to get it going today. Did the basics. Pulled plug, checked for spark, cleared cylinder, squirt some fuel in cylinder and intake and she fired right up. Put water to her and she acted like she seized up. Quick search points to the unloader valve, which I had no idea about. I used it all day after I figured out that once I relieved pressure by pulling hose wand trigger, it would free up and start again. As long as I ran it and kept the trigger pulled it ran perfect. There were a few times it ran perfect intermittently and would stay running once I released trigger; but that was short lived. NOW I KNOW. I’ll check tomorrow and see if that is the culprit. I’d guess it was based on how rusted the pressure hose was (nearly rusted SHUT at the pump connection).
Thank you SOOO much for the video! Didn't check my 100' hose before connecting to a bargain on Marketplace. Worked for about 4min then trash started to plug nozzles. I'll try and clean and see what happens.
I found this video looking for something else as most of us do. I thought this is going to be to complicated to follow. You engineered the hell out of that explanation to get a fact. That sir was awesome! I wish we had worked together back when. Thank you. I'm saving this
You are very correct with the statement of limited information available. After scratching my head, I stumbled across your video. Thank you Thank you Thank You for this information! It solved my issue and now I’m back up and pressure washing. Did I say say thank you?
My unloader looks identical except for the end that yours has the spring in (3:28 of the video). Mine is all one piece so there is no removing it with pliers and pulling the spring out, or tapping it in until it releases as seen on every other video. Mine is a solid one piece of brass so I have no idea how it actuates the ball bearing. Oddly, when I removed it from the pump housing, there were pieces of broken spring around the outside of that pin, so think maybe that’s what somehow actuates the ball bearing. I used a spring from a ballpoint pen in its place, to no avail. Guess I’ll have to “spring” for a new pump. It’s an older Craftsman, and has run flawlessly for 10-12 years. Pump housing says Made in Italy! Guess a functional pump from China is better than a broken one from Italy. They don’t have that exact pump available anymore. Thanks for your time making the video.
I needed to do that several years back-(like 2004) but was always afraid to take it apart...bought a new pump for 50 bucks and gave the old one away.... geesh. a few minutes of unafraid tinkering would have been soooo much cheaper! DOH!!! thank you for explaining it all, I am sure it's going to come in handy!
I tried to tinker with mine, but didn’t realize the whole unloader valve assembly came out. Just bought a new pump for it 80 bucks (that’s how much they cost now) wish I would’ve seen this video first…
Took my unloader valve out and the tip was working properly & there is no debris in the two little holes on either side of the tip. Reinstalled the valve and I still have no pressure, so I'm guessing I need a new pump. I don't know anything else to check. Water flows freely through the machine and the nozzle when the supply source is turned on, and the PW fires right up with no problem. I was using it yesterday, had to stop and back up my car to get to the area, came back and the pressure at first was very high, then in about a minute it stopped and now there's no more pressure than if I just used the wand without the pressure washer working. I do appreciate the video because I also had no idea how this worked. but mine is working as yours so it must be the pump.
Thanks for a clear video. Troy built unloader valve doesn’t hat the tiny spring mechanism on top, it’s have the large stuff spring on outside like yours. My problem is once it have pressure it’s won’t spray or leak any water out but when I loosen the unloader then I’d get some water dripping out.
great video sir, this is just what i needed to see my washer has been playing up a bit, I will check this on my washer I only used it once and now it's not getting enough pressure.
Very helpful I had that exact problem with a used power washer along with gas shut off problem. All fixed for $6.00 a 3000 psi paid $5.00 for the machine. Thank you :)
Hey there....I'm having the same issue with my craftsman......how did you remove your unloader........MINE IS ALMOST PART OF THE CAST IRON it is so hard to take off.....wondering if it does........I mean it does have the "retainer" so I'm sure it has to come off.......what model do you have? Mine is pretty old as well.......thanks!
You're the man! thank you for putting this info out there for all us. just got a freeby from a guy at work. he said it shoots water, but only out the back! lol keep on brother!
Well explained and just as I was going to order a new pump I came across this video. My pump is only 2 years old and no pressure so assume what you explained could be the problem. Thanks again Great Video !!
I know your posting was is 3 years old, but I'm having the same problem you were. Mine is only 2 years old and when I squeeze the trigger there is a huge amount of pressure for 2 second, and then just dribbles out. Happens every time. Did you need to replace your pump or was it this problem?
@@garytman007 I found out if you keep pulling the trigger on and off it eventually clears the air in the pump ( air bound) I have picked up 2 free pressure washers that had the same problem and when I did the on and off it cleared the air in the pump.
@@scotsmanofnewengland7713 thank you for the prompt reply as I will be trying your method tomorrow! If that doesn't work then I will look at the unloader valve. Thanks again!
@@garytman007 Also at the end of the season if you live where gets cold below freezing like here in New England. I would run some pressure washer lube thru the pump. It forces out all the water and lubes the springs inside. The lube is available at Lowes,Home Depot and any good hardware store. Seems some don’t do this and the pump freezes and cracks from the left over water inside. Thanks and good luck.
Great vid there, I've got a "low/no pressure" issue on my Nilfisk, motor runs fine, I've been told to check the bypass valve, aka unloader valve - fingers crossed this is the issue
Thanks Corey....My Simpson was working fine today. athen after taking a break .... no pressure. I found your video and another. My "plunger" was not stuck and was going and forth just fine. not sure what to do next, could that little ball baring in your illustration be stuck in the "no pressure" position? Thanks for video and input C.
I think this may be the issue I’m having.I squeeze trigger on wand it initially comes out with pressure but immediately kicks off. Seems the unloaded valve is the main culprit that has everyone either throwing their pressure washers away or being sold an entire pump assembly at almost the price of a brand new machine.Clearly this apparatus is the nerve center that needs cleaning and lubrication,thanks for sharing and clearly explaining.
Did this fix of the unloader valve solve your problem? I am having the same exact issue you were. 3300 ryobi gas powered not even 2 years old yet. I'm hoping this was your fix.
Great vid. I wonder, whether the unloader is involved in the failure of my Kärcher 720MX, which doesn't stop the pump at maximum pressure, when the machine is on, but the spray gun isn't opened. Is there a pressure switch, which cuts the voltage to the pump? Regards Heinz
Thank you for a great view and understanding. I have an issue where it is blowing out at the brass nipple next to the unloaded valve. Have done a full seal and valve replacement with no luck. It still will not build pressure. Any ideas greatly appreciated. Looks like pump replacement?
Same here. At first, all pressure shot water out of the port where soap is supposed to go in. I freed up the stuck unloader plunger, and now half the oressure goes out of the soap hole, and half goes to the gun. NG.
Thanks soooo very much! Awesome video, especially with the cutaway view to reveal the actual operation of the piston. After removing the unload valve and taking it apart for cleaning, how do you know where to set the tension on that spring when the valve is re-inserted? BTW, ignore the haters who gave a thumbs down. And remember...it's easier to destroy than it is to create!
Wyo WindStorm, I’m not sure as I’m no pressure washer mechanic. I’m just the type of guy that likes tearing down broken stuff to see what went wrong. But I have heard that if you tighten the pressure adjusting nut too tight, the motor will die trying to make that much pressure.
7 years later you're still helping people with this video. Thank you
WOW!!!!! 5 years later and your knowledge is still saving the day and only took me 7-8 videos of people who, I don’t know or can’t say what their talking about but if I listened to half of them I would have purchased an entire new pump but thought, DAM I only have 2 hours on this $375 rig and it just can’t be the pump but then I found your video and BINGO!!!
Such an easy fix and will now know it until my dying day!!!!
God bless you brother 🙏🙏🙏
Your pump sacrifice was not completely in vain. The cutaway visual helped me tremendously diagnose my own issues. Thanks for the video!
For every single video like this one that gets straight to the point, and uses the proper part names, there are 8 or 9 others that are little more than blah blah blah, posted by guys who don't always know or use the correct lingo, either. They're oftentimes examples of how NOT to say or do things. Such is the price of having a platform like UA-cam that has no barriers to entry. So...thanks very much for your efforts here, Mr. Morgan.
I have a Homelite 2200psi gas pressure washer that stopped working. There were no leaks in the pump but there was very low pressure. I took the pump apart and unstuck the little piston with a few taps from a screwdriver handle just like this video says. Put it back together and it now works perfect with full pressure. Thanks, you saved me the price of a new pump!
Thank you Sir. All I had to do was tighten that valve!? Repair shop wanted $150 to diagnose my issue of low pressure. Saved my life!!!
Excellent video. Never saw a cut away not produced by a company to show their products. Thanks for the time you devoted.
UPDATE:1 year and still cranks within the first 2-3 pulls. Probably will buy another when this one finally does bite the dust ua-cam.com/users/postUgkx43QMbQqu67IZadu9ou8Sg1BdrunMRNqX . No issues at all. Very happy with it.UPDATE: After 6 months of use and over 70 uses I would still highly recommend this pressure washer. It does vibrate a decent amount but never had it “walk” like others have mentioned. No oil leaks, still seems to run like the day I bought it. Still cranks within 2-3 pulls every time. Very happy with my purchase!Have used it about a dozen times now. Plenty of power, cranks up on 1-2 pulls every time. My only complaint would be I wish it was a little taller to make it easier to walk with it (hits my ankles a lot) and that the two hose connections were a little further apart but it hasn’t caused me any issues. Seems to run a good 1-1/2-2 hrs on a full tank, overall a well built machine and definitely worth the money in my opinion.

As was stated, love the detail and directness of the video. Thanks for helping me understand the functionality of this valve.
Fantastic - that little device has caused me confusion until I watched your video!
Nice video. You are the only one who shows the second inside piston!!!! I checked my unloader but didn’t check that! Hopefully you will save me from buying a new pump!!
Hey Corey! Thanks very much for taking the time to put this video out there for the rest of us. The cutaway pump was outstanding and the total disassembly of the uploader is exactly what's missing from every other video I watched on this problem. Thanks again and take good care.

I do appreciate the video because I also had no idea how this worked. but mine is working as yours so it must be the pump.
Thanks for a clear video. Troy built unloader valve doesn’t hat the tiny spring mechanism on top, it’s have the large stuff spring on outside like yours. My problem is once it have pressure it’s won’t spray or leak any water out but when I loosen the unloader then I’d get some water dripping out.
You have a future in UA-cam videos - this was VERY HELPFUL. Thanks. Not kidding about the UA-cam thing............
YOU ARE THE MAN ! THANK YOU FOR THAT EDUCATIONAL AND INFORMATIVE DETAILED video !
Great video !!! I did change the fluids on my electric washer presure pump and replaced one of the o rings. Now it runs like brand new. Subscribed !!!
great video sir, this is just what i needed to see my washer has been playing up a bit, I will check this on my washer I only used it once and now it's not getting enough pressure.
Very helpful I had that exact problem with a used power washer along with gas shut off problem. All fixed for $6.00 a 3000 psi paid $5.00 for the machine. Thank you :)
Ohhh nice now i know exactly what my actions towards the valve will do and how it works... Thank you good sir
Man!! Thank you 😊 you saved me from buying a $200 dollar pump, It was just stuck. 😁
Thanks for making this video. Short, to the point.
Your awesome! Thank you... You have no idea how much you posting this video helped me.
God job with cutaway! Very informative!😊
Very good ..
Its nice to see a detailed video.. when you know what its supposed to do, and, what to look for, it makes diagnosing a lot easier.
Thanks
Holy crap you just showed me exactly what I needed to see, whether there's two or only one teflon washer at end of that plunger..Thanks for this!!
Thanks a million for the cutaway visual!!!
You have just saved me a TON!!!!! of headaches....
Thank you! Great detail and helpful to know. I'm having a pressure issue and will give this a try to fix!
Thank you. Right on the money, mine was on to tight. Nailed it and I’m back in business. Thanks buddy
thank you sir !! finally somebody reveals the mechanism.. makes it much easier to troubleshoot !
I think that is exactly why my pressure washer is not pressuring
Thanks for the video
I will try
Thank you for video. The cut away is awesome
Thank you...fixed my issue in less than a minute. Pulled it, tapped it on ground and replaced.
Great video! Thank you for saving me and others a lot of time and searching.
good job... i got my 15 year old craftsman washer working again...thanks...
Hey there....I'm having the same issue with my craftsman......how did you remove your unloader........MINE IS ALMOST PART OF THE CAST IRON it is so hard to take off.....wondering if it does........I mean it does have the "retainer" so I'm sure it has to come off.......what model do you have? Mine is pretty old as well.......thanks!
You're the man! thank you for putting this info out there for all us.
just got a freeby from a guy at work. he said it shoots water, but only out the back! lol keep on brother!
Well explained and just as I was going to order a new pump I came across this video. My pump is only 2 years old and no pressure so assume what you explained could be the problem. Thanks again Great Video !!
I know your posting was is 3 years old, but I'm having the same problem you were. Mine is only 2 years old and when I squeeze the trigger there is a huge amount of pressure for 2 second, and then just dribbles out. Happens every time. Did you need to replace your pump or was it this problem?
@@garytman007 I found out if you keep pulling the trigger on and off it eventually clears the air in the pump ( air bound) I have picked up 2 free pressure washers that had the same problem and when I did the on and off it cleared the air in the pump.
@@scotsmanofnewengland7713 thank you for the prompt reply as I will be trying your method tomorrow! If that doesn't work then I will look at the unloader valve. Thanks again!
@@garytman007 Also at the end of the season if you live where gets cold below freezing like here in New England. I would run some pressure washer lube thru the pump. It forces out all the water and lubes the springs inside. The lube is available at Lowes,Home Depot and any good hardware store. Seems some don’t do this and the pump freezes and cracks from the left over water inside. Thanks and good luck.
Thank you guy your video helped tremendously... I have a chinese 3500 psi pressure washer thats never felt like it made 3500 psi
Thanks , excellent video. Also , like the knee saver you are kneeling on.
Great vid there, I've got a "low/no pressure" issue on my Nilfisk, motor runs fine, I've been told to check the bypass valve, aka unloader valve - fingers crossed this is the issue
Easy fix and saved a lot of frustration and money. Thanks
thanks many times - i've wasted so much time trying to figure this out . BAM!!!
thanks for the disassembly in cutaway old school
Thanks for the great video and cutaway! I was worried the slide pin holding the assembly was under spring tension 😅
Thanks Corey of that info but what if your water pump built up pressure and the thermal release valve kicks in
Great educational video on water pumps! Thanks for sharing your knowledge and time!
Nice Video, thanks for taking the time to make the cut out view
Thanks Corey....My Simpson was working fine today. athen after taking a break .... no pressure. I found your video and another. My "plunger" was not stuck and was going and forth just fine. not sure what to do next, could that little ball baring in your illustration be stuck in the "no pressure" position? Thanks for video and input C.
I think this may be the issue I’m having.I squeeze trigger on wand it initially comes out with pressure but immediately kicks off.
Seems the unloaded valve is the main culprit that has everyone either throwing their pressure washers away or being sold an entire pump assembly at almost the price of a brand new machine.Clearly this apparatus is the nerve center that needs cleaning and lubrication,thanks for sharing and clearly explaining.
Did this fix of the unloader valve solve your problem? I am having the same exact issue you were. 3300 ryobi gas powered not even 2 years old yet. I'm hoping this was your fix.
Great Job explaining the workings. Thank you
Thanks for the video! Great explanation and demonstration. Your still helping people to this day! Thank you!
Great vid. I wonder, whether the unloader is involved in the failure of my Kärcher 720MX, which doesn't stop the pump at maximum pressure, when the machine is on, but the spray gun isn't opened. Is there a pressure switch, which cuts the voltage to the pump? Regards Heinz
Much love to you!! I was ready to smash my pressure washer! Pin was stuck! Thank you so much!
Thank you for a great view and understanding. I have an issue where it is blowing out at the brass nipple next to the unloaded valve. Have done a full seal and valve replacement with no luck. It still will not build pressure. Any ideas greatly appreciated. Looks like pump replacement?
Same here. At first, all pressure shot water out of the port where soap is supposed to go in. I freed up the stuck unloader plunger, and now half the oressure goes out of the soap hole, and half goes to the gun. NG.
Thanks soooo very much! Awesome video, especially with the cutaway view to reveal the actual operation of the piston. After removing the unload valve and taking it apart for cleaning, how do you know where to set the tension on that spring when the valve is re-inserted? BTW, ignore the haters who gave a thumbs down. And remember...it's easier to destroy than it is to create!
Wyo WindStorm, I’m not sure as I’m no pressure washer mechanic. I’m just the type of guy that likes tearing down broken stuff to see what went wrong. But I have heard that if you tighten the pressure adjusting nut too tight, the motor will die trying to make that much pressure.
@@AK907dude same question. Or how can I install a gauge ?
Thank you for this video. On the other hand, does anyone know what part number that bearing is on that unloader valve is. I can't find it anywhere.
