How to easily repair a KARCHER pressure washer! 😎👍👌

- Only if I knew how to fix a"pulsating" Karcher Jetwash a few years ago I would have save a lot of money. I have been using KARCHER Jetwashes for over 10 years and only until recently I figured out that it wasn't broken after all, the nozzle just needed cleaning!
The jetwash sounded awful and kept "pulsating" like there was a problem with the motor. After all this time the nozzle was blocked and it just needed a good clean.
It is so obvious to me now that a small piece of sand/grit was stuck in the nozzle and just needed knocking out and cleaning. - Навчання та стиль
So I've only used this pressure washer one time. ua-cam.com/users/postUgkxfQauTxLT0JLSvqkq10rD79TU4k0Vz8zP The one time I used it, it worked great. I recently had new siding installed but kept the old gutters and small areas surrounding my house that weren't replaced so they looked horrible and dirty because of the new siding. I needed to get it cleaned asap. When I used the pressure washer, man it just melted all the dirt and grime that was on those areas of my house. I used that krud kutter soap and it was over after that. Easy to assemble, feels durable, very simple to use. Also, I purchased a used one to save money and there was absolutely nothing wrong with it. I want to get more use out of it so I think I'll be washing the cars and update this comment as time goes on.
thanks for the comment!
Great ! easy fix indeed thanks to your video. My k5 is back to life. 👍
Cheers bud, I've just done this exact hack and its given the Karcher a new lease of life.
Good luck we need someone like you to help us repair instead of throwing away when sometimes goes wrong
Just grabbed me Karcher out of the bin because of this video!!! 😆🙌🏽
Love it!!
Thanks for this. I had exactly the same symptoms with the patio cleaner attachment. Even though water was getting through both jets, it was pulsing. After seeing this video I took the jets out and sure enough, one of them was sufficiently blocked to have caused the problem. All brand new now!
Glad you fixed it mate!! Just make sure the hose end doesn’t get any sand etc when you connect it to the jet wash or time for another clean lol
Thank you so much, I was just about to buy another nozzle, a 3rd one, you’ve saved me a fortune!! And all thanks to a simple pin, genius!!👍👍👍😢
My brand new Karcher k5 smart control started doing this after 3 mins of use. Tried this and it worked a charm. Thanks!
Great happy to help!
Dude you just fixed my pressure washer.
Thanks so much.👍👍👍👍
Very helpful, followed your advice and fixed mine too. It's also worth trying to unblock the jet first without dismantling as that may work for a minor blockage.
Glad it helped
Thank you for sharing the knowledge.
Brilliant…just what I needed. Great video - very grateful. 👍👍👍
That really helped me out a lot! When I opened it up, I didn´t see anything wrong - there was the hole in the nozzle and I could see thourgh it. But I cleaned it anyway and notized it became oval. It did the trick!
Happy to help!
Dude, you're a lifesaver. Thanks
Happy to help!
Brilliant….. worked a treat, thanks!
Will give it a shot tomorrow. Cheers from Austria
cheers for the comment
You’ve also got a leak somewhere as machine is pulsing. It’s a home and garden machine not designed for commercial usage
74yo F trying to fix Karcher pressure washer. Took the yellow thing 😁 off to see where water was spewing from inside. Found 4 small holes where 89yo hubby left water to freeze😱😡. Thought I could buy that part but what is it? Booklet? Oh heck no!😵💫
Liked your easy, explainable tutorial. Thanks
No problem glad we could help! Thanks for comment
Thanks for this. Just about to follow your vid in the hope I can fix mine.
Wish me luck 🤞
Good luck!
💪 amazing easy fix, thank you

Hi thanks for the video. which helped me sort out this exact problem with my Karcher. I have a Karcher with the three jet option spray nozzle that you have in your video, and like you, I couldn't remove the small yellow plastic section that has the last two screws underneath it (there are 8 screws in total for this spray nozzle cover). This yellow section is retained by two "clip"sections in the black plastic pipe, that have to first be squeezed inwards. These "clip' sections can be seen when viewing the black plastic pipe from the end. However forcing these hard plastic clips inwards whilst also trying to pull the yellow plastic section over the top of it, was at first impossible. How I solved this was to drill a very small hole (about1.5mm) through the top (end) of each clip section , again looking end on, and then installing a very small screw into each hole. These two very small screws allowed me to use a set of long nosed pliers to squeeze the clip sections inwards, with the yellow pastic cover then easily pulled free of the clip section.
The reason I needed to open up the spray nozzle cover up completely was because the small metal tab that notches the movement between the three spray nozzle options, had dislodged whist removing the first 6 accessible screws. I have now super glued the small metal tab in place.
I hope explanation makes sense for others trying to remove this yellow plastic section from this particular model spray nozzle
Hi I had the same problem but I can’t find now where the metal bit comes from. Could you help please?
Hi,Maria,
Have you been able to first remove the last two screws located under the yellow cover as per my first post ? With all eight (8) screws removed the Karcher wand head comes apart in two halves for this particular 3 jet model. Regards. Stephen
The small metal piece is from the middle of the power gun (right next to last 2 screws - yellow plastic) and stays horizontal and perpendicular through the power gun
I think you’re awesomely smart.
Why thanks!
Very useful. I will have a go. Particularly helpful as I have exactly that 3 in one model. I hav a second issue too that the electronic display isn't working either but I can live without that.
Cheers for the comment
Just change the batteries, easy as that. It's two AA batteries and you just slide a small yellow tap to access the compartment. Bought mine used (K5 Premium + accessories) for £150, which was a steal, because the owner thought it was broken (i.e. the LCD display not working).
Great tip, will definitely be taking apart the K5 Premium lanse later this afternoon and see if I can get the rotating nozzle going again, as it stopped working yesterday after hours and hours of cleaning. Am genuinely surprised that dirt finds it's way in the nozzle since it's a quite closed system that only receives water.
its grit on the nozzle before you connect to the jetwash, it may have briefly touched the floor etc, it only needs a grain of sand
@@thep0ndmanfor me it's a worn down plastic insert; even if you fix it using this approach with the washer insertion, it's going to get worn down eventually.
Grazie proverò il tuo consiglio!!!!!
Cheers
The metal clip goes back on one side of the outer case about half day down. the inner nozzel that doesnt come out has a grove going in, the metal clip groove going out so it clips into each other. You really have to pull the outer case apart as much as you can to see it not easy.
I tried the cleaning but didnt fix the spinning cleaner and the second one only the flat spray one works.
Thank you..
Great thanks
👊
I’ve got the same washer, but it won’t turn off even when switched off so I’m sure the switch in the electric box is sticking. But also getting water trickling out from either the control head or the bottom of the pressure piston stem. Hard to tell where exactly it comes out from. Thinking I’ll just change the control head completely.
It would have been useful to mention that the screws are Torx screws and to also mention their size. Otherwise very useful 👍 Your camera work and presentation will become more slick as you move forward. Have a looking at Cutting Edge Engineering which is a one man band, like you, who’s wife does most of the camera work and editing. Lots of useful techniques to provide guidance. Keep up the good work and keep safe.
👍
Cutting Edge Engineering for the win, best technical content on UA-cam by far.
thank you
You're welcome
New Subscriber 😊 This was definitely worth a try as I have the exact problem you describe/show (lance with the 3 settings). Sadly, it didn't work 😩... in your experience, would I be right in thinking that the lance is normally the problem (as opposed to the handgun, which suddenly - mid wash (same time as I experienced the weird pulsing/lack of pressure) - decided not to recognise the 'normal' pressure washing setting/allow me to increase or decrease the pressure and continually flips to that weird/useless helicopter setting when you're trying to increase the 'normal' pressure setting?) Thanks for any advice you can give - really appreciate your time and effort helping others! 🙏🏼
Thnx for comment. Did you def clear the nozzle properly? Thnx for the sub!
Great stuff. I have the same unit but the soap dispenser doesn't work anymore. Help please 🥺
My k4 is doing this lucky for me i have my K2 as back up on a job.
I've not done this to the lances yet but I did try the lances on the K2 & they worked fine. I'm wondering if it's the hose on the k4 that could be blocked up so I'm gonna wait until the new hose arrives & hopefully this could sort my issue out.
thanks for the comment!
My k2 doesn’t have the screws to undo like yours, how do I clean mine ?
where did you put the metal part that was in the 3in 1 tool?
Very good question…
I have a K7 issue with the nozzle making the same noise as yours, I opened it and cleaned it up. There's a flat metal not really flat, on the first nozzle that you opened(the one that you could not open very well) and I don't know where it came from. Please do a quick on how to put it back as I have searched on the internet with no luck, looking forward to your reply.
Thanks for the video. It helped me unblock my 3 in 1. Is the 5 in 1 as good as the 3 in 1, same pressure? Might go for an upgrade
Hmmm…to be honest I think the 3 in 1 is better or higher pressure. The 5 in 1 has a nozzle that blasts out a straight line of water but we don’t really use that but may be better for you.
@@thep0ndman thanks for the quick reply. Iv actually read somebody saying just that, so will probably stick with the 3in1. I was also looking at the dirt blasters but they seem to break quite quickly. Cheers
Love KOI fish
Where should i put the metal piece that fell out of the 3 in 1 nozzle?
not sure it works without
Where does the small metal bracket (visible around 4:40) go when it’s time to re-assemble?
Good video! My washer has no power! It was working fine last time I used it, plugged it in and nothing! Any ideas?
Not to sure why it does that sorry! Check your fuse I guess in the plug
Any luck where the metal clip belongs, mine fell out as well and I don't know where it belongs?
nope sorry
My K5 smart is stuck on mix mode on the display. Any fix for that?
Hi mate, any idea what could be wrong if the pressure is quite low? Turns on normally but the pressure wouldn't be enough to wash a patio (barely enough to wash a car) It just happened one day and haven't been able to fix it since! Any help/advice is greatyl appreciated :)
Check hose isn’t kinked perhaps and water flow is getting in properly
Check your digital display. I have the same issue and mine is blocked on "foam mode". I will check tomorrow morning if this guy tip with unlocking all of them will change something
@@mihairachita174 Good tip. My digital display is not showing at all so goodness knows what I am locked on to.
Hi, my Katcher K4 Full Control is making the same (grrr) noise when its on and not being used. Is this normal ?
Any ideas on why a k4 power control isn't reaching top pressure, gets to medium, but no higher. TIA
if using old connectors may be worth trying new, it could be drawing in air from somwhere...
Hello sir, great tips. One problem I am having is my Karcher K7 turning on, working for 30secs/1min, then it stops. Then it goes on again. Any known reason for this? Could it be air or dirt?
Thanks for comment. Sounds silly but is the hose on or kinked?
Is the water pressure coming from your house water pipe. You got low pressure going into the karcher
Mine is doing that but is not from that🤦🏻♂️ any other ideas?😬
Hi I have a karcher K7 full control jet wash & I have dissembled the hand gun (the part with the display on) and I can’t get it back together 🤦🏼♀️ as I’m trying to find an airlock as the water is still spluttering from the hose after bleeding for 30 minutes.
I have cleaned the other nozzle as in this video , so decided to see if there was a filter in the hand gun with the trigger 😢
TIA
Does it pump water when the twisty nozzle has been removed? If so then the nozzle is still blocked if not the jet wash it self is broken
@@thep0ndman hi thanks for your advice unfortunately I had to send it back to Karcher for repair fortunately it is still under warranty🙏🏻, I will let you know the issue once I have had it returned in case it helps anyone else
Mine does... Minus the hip gyrations though 😂
lol
My k5 has the pulsing problem but its the the actual machine part not the gun, when the gun is being used all works fine when you stop using the gun it starts to pulse like yours is doing any idea what it could be
If you take the nozzle off and and just use the gun does it work ok then?
Hi my spray gun Karcher K5 UM hose doesn't click in? it just comes out? I have bought a compatible spray gun and the same things happens. Any idea?
Change the hose nozzle
Any ideea where goes the tiny bit of metal?
no. it works without just doesnt click as you turn it
Please help me address the issue of my soap dispenser. I attached the bottle of soap to the spraybar but when I press rhe trigger, the whole thing doesn’t work. How can I overcome this?
hmmm sorry not sure never used it! thnx for the comment
That's an easy fix, but in the background I can hear your karcher starting and stopping without pressing the button.....what is the reason?
Thanks!
Not sure why it does that but still works for us cheers
@@thep0ndman
Ok
Thanks!
Mine is pulsating without any nozzle on but doesn’t it I completely unscrew the hose
that little metal clip thing with an arch that appears at 4:09, where did that come from? I can't seem to find where to put it back, thanks!
I don’t know, I can’t even remember putting it back so maybe I knocked it on the floor my mistake. Sorry mate! Mine still works fine though
@@thep0ndman hmm ur right I reassembled the wand without that thing and it still worked like a charm this morning! Tickidy boo! I found zero info about that thing wit karcher either, probs some trick piece that's used to determine if u opened it urself and void warranty.
@@staitroo I left that little piece out but when I twist it to change settings it doesn't click
Same here! It no longer clicks when you change the setting. Where does it go?!?!
Great video by the way. Didn’t find a blockage but will check to see if it worked in the morning. 😊
For mine.. it's just the machine that does the pulsing. Not the nozzle. (When I turn it on it immediately starts pulsing. Without pressure/water though. It's just little energy bursts.) Anyone know anything about that? 😬
there is a small metal plate you do not show how to install it back to the multijet. If possible, give some clue on how to install this small metal plate back with great thanks!
Ill check for you!
@@thep0ndman thank you so much, it looks with this small plate,when turn to make selection, there is a "k k " sound, while without this small plate or do know where is the right location, turn to make the different function selection, there is no "k k" sound. so it looks just a part to make the "k k" sound when turn the head to choice the function. it is just my guess. and I find that in you video, at time 4:09, the small metat plate is at the table under the washing gun.
How about too much vibration.poor pressure?
not too sure about that ours have always been ok. Make sure the hose nozzles aren't damaged as it could be sucking in air so it not compressing properly...
Do yourself a favour mate, ditch the karcher and get the Ava washer. good luck. A
Lol karchers haven’t been too bad in regards to the machine itself , fingers crossed!
