Trying to FIX: Karcher Dirt Blaster Lance NOT Spinning
Вставка
- Опубліковано 16 вер 2019
- Hi, this 'trying to fix' videos shows my brother Paul and I attempting to repair a faulty Karcher pressure washer lance. This lance is called a Dirt Blaster and it has stopped spinning, it also causes the pressure washer to cut in and out.
Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things.
I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series.
Many thanks, Vince. - Навчання та стиль
Excellent! Who knew that repairing pressure washers would be fun! I had to do a repair to mine many years ago - left water inside over winter, it froze, expanded and cracked a piece of aluminium on the pressure part. Luckily I sourced a replacement part and it was good as new! Now I always make sure to run the jet washer without water until all the water is expelled from inside, then store it for the winter.
Thanks for posting this, would have never thought the end of the lance was screwed on which makes it repairable. Great work and keep it up.
my job is fixing karcher machines, and i have to say that the plastic dirt blasters do wear out very fast and then stop working properly. the brass versions last much longer
The various fixes are pretty good. I wonder if it's possible to get after-market parts. What size washer is used in the fix? The dimensions are given in the video, but the metric or English size is not. Any thoughts? My metric pack does not have an exact size to fit. How does one obtain the brass bits? What is the proper name for the rotating bit with the ball bearing in?
@@hanwachtel there is not always a repair kit available. If there is one available, you can find parts list on internet with the type number of your karcher machine. The type number is on the white sticker that normally sticks on the back or side of the machine, its a 8 digit number for example : "1.520-093.0" . There are some repair kits available on ebay.
so why dont they just give us a brass one then ffs 0.0.
chrismechanic B because then how would they sell you a repair kit?
Thanks Vince, was using mine today and came in for a brew because the nozzle stopped turning. Perfect timing for your video. Job for tomorrow.
Thank you opening my eyes to repairs that I could take on myself. Now you show how strip down the gearbox in my Audi A6.👍
i suppose you have that silly auto gearbox problem...
Brilliant video Vince. You and your brother worked together and figured out a brilliant result. Hopefully it lasts a good while longer while you look for a more permanent solution or repair kit. As always great video!
Very good fix guys!!! I have an older unit which has similar parts. I used a plastic washer that was adjusted to the right
thickness... a lot of fiddling around is needed.
I love watching investigative fixes! Great work gents.
My dirtblaster was broken in the same way and this video was a perfect fix for me. No faffing about figuring it out. Thank you
I've got the same problem with mine, will give you're fix a go, cheers for that mate
Great informative video ,thanks for sharing it with us . I am having a problem with my patio cleaner not working .
Iam kind of handy man and I got little experiance to do many trades ,this chanel is one of the best I have ever seen and since I started watching UA-cam for many years iam subscribed only in 9 chanels and now I have 10 chanels including yours ,keep it up mate 👍👍👍👍👍👍👍
I know, what to do when & if my dirt-blaster starts being a arse. Mine shouldn't as, it's less than a month old 😄 But, many thanks for your solution to a problem that could have had a cost to it. ( a new, replacement dirt blaster at a cost of 😕 ) Your solution with your brothers help 😁 has saved money on forking out for another. For those who may need to do so in the near future. THANKS ANYWAY!!!! 😉 I wonder what would be the, solution if the various lancewood, had issue's Maybe a video in the future, showing how, to deal with that, . I'm sure, they are, quite, a bit more complex, at the nozzle. Once again THANKS!!!
Excellent vid guys. Funny I stumbled upon this because my exact lance on the exact machine has just developed the same fault. Many many thanks.
Thanks for posting this. your video is excellent to watch to the point not boring at all. very lively and focus to watch. also like your approach it is not a fake video as there are many nowadays showing stuff that can't be put in practice. Yours is genuine. When fixing anything issues crop up as it is shown in your video. Step by step you showed logic approach.. Best wishes & keep it up. Thanks again.
Great Vid. The key design element of the lance is that the ball bearing must protrude from its housing, thus allowing the unit holding the ball bearing to spin. I have a K4 Karcher where the ball bearing sits in a solid tube with no hole to let the water through. I created a copper disc that now sits in the bottom of the tube allowing the ball bearing to protrude the correct distance and it now works like new. Thanks (if you're still monitoring the vids)
what a great video, very thorough in trying & results.
mine (Karcher K2) was having the same problem with its dirt blaster nozzle. thanks for the video.
Thank you for solving the karcher problem, cheers
I agree with your conjecture that the ball bearing wears down the plastic support mechanism. I couldn't locate a washer as small as yours to bring up the level of the ball. Mine was barely above the top of the plastic retainer. So I drilled a 1/16" hole in the sides of the retainer, just above the cross members, and inserted a copper wire across, bending it up to retain it. The blaster now continues to run, albeit not as smoothly as before, but at least it gets the job done. Thanks for your insight.
Thank you . I am experiencing this issue at the moment so this knowledge is a good way how to start fixing mine Kärcher.
I've just had to take my one apart too. It's a GreenWorks model. The jet nozzle has a 6mm allen up in it's rump and it's REVERSE thread. My one was built almost the same. I polished the bits that slide on each other with 2000 grit wet/dry paper and gave it a light tough of silicon grease. Job done!
What a coincidence, I literally set my karcher blaster up earlier today and I come on youtube and this video is waiting for me
Great job guys, I have the same issue and will have a go at this
Very Impressed the way you and your brother worked it out .

Great video! Mine has the same problem, so next day I will try your method 👏👏👏👏👏
Thank you very much for your help! 😉😉👍👍
very necessary info! we also have hard water and i immersed the nozzel in white vinegar for a couple of days which dissolved the minerals, largely calcium and magnesium [scale] and it seems to have done the trick - a squirt of oil/silicone now and then could also help. if there is dirt inside obviously opening the unit will be the solution.
Thanks for the video , my karcher suffers the same problem. I shall check tomorrow . And now one borrow their tools to anyone . I don't know is it just me or there are others out there, WHEN EVER YOU LEND YOUR TOOLS TO OTHERS, IT'S NEVER THE SAME WHEN AND IF ITS GET'S RETURNED.
Great way of fault finding. Well done..
Ok watched. Agree with your diagnosis. Would offer that if you take a pencil and press the washer onto some 120 grit sandcloth with the eraser end, that after 5-10 min of sanding you can adjust the thickness of the washer easily. Sand two washers down to 3/4 original thickness!
Excellent trouble shooting. It is very useful to me. Thanks guys.
thank you for sharing. I have just fixed mine👍
Thanks! I wish you good health and good luck!
Hi vince thanks to this video y jet wash was doing the same thing but on the 4 speed head version when I went to hi it was making the same noise and pump going on and off so after watching this I took the head apart and there was some dirt in side cleaned out and now works great almost brought a new jet washer thanks again would like to chat with you privately about something if you have a min
Not all heroes wear capes! Thanks for this guys!
Nice fix!!... from one Karcher repair person to another. I will try the washer fix on my rotary wand.
cheers!
Thank you for your valuable intructions.i had two defective nozzles and managed to repair.how to repair the other long one?
Vince and Lance. Could be brothers!
Had the 'Karcher power washer advert' stuck in my head the last couple days and then this video turns up in my feed. How strange:)
What a fantastic video Vince! I've got a how to fix video coming up later on from our dryer. When it was turned on it sounded like there was something rattling about in the motor, but in fact it was actually a bit that I had changed out a few months ago that had fallen down the lint trap and was causing it to make a loud rattling noise and sometimes to stop the motor entirely, of course the lint trap was also full of crud as well and it leads directly to the blower. Here I was thinking I'd have to tear the whole thing down and replace the motor lol 🤷♂️
I spent years working for Karchers Rn'D department. Have you ever wondered why the fitting wears down? Well we could have made it from stainless steel, but instead we tried numerous plastic designs. A lot of work went into finding the perfect plastics blend. We needed the fitting to last just long enough so we could be sure we wouldn't have warranty issues, but not too long. A lot of time was spent researching how long the average consumer uses their Karcher. Once we had an average we simply used a plastics blend that was purpose designed to wear out within a given time. Needless to say we charge way over the top for new lances (nearly a third of the purchase price of the jet washer), but hey that's just business! Stainless steel would have lasted a lifetime, but now we sell hundreds of lances.
Ok I never worked for Karcher, but somewhere someone would have been involved in the design and you can be absolutely certain that the fitting was made of plastic for exactly this reason.
I've fitted a copper disc in the bottom of my K4 ball bearing fitting and it now works like new. So the £54 for a new lance will stay in my bank account!!!
@@999shakers Good for you, I hope it lasts.
From diagnosis I am certain that this was dropped and it damaged the inside by changing the length of the stem. Because the length was short the stem was flopping around inside the nozzle and getting stuck till pressure built up dislodged it and lodged it again. Sorta why you feel that pulsing pressure at the start. I From what I can see this is how it works. The inner height of the nozzle assembly is actually shorter than the stem itself. This forced the stem to rest on the outer edges of the radius inside. When water is turned on the water is forced through that small pin hole near the top giving you that high pressure. This flows down the stem and around the bearing(ball). This ball gives the stem free movement around the radius of the orange piece and the small rubber washer acts like a bumper to protect the stem from slamming into the sides of the nozzle at high rpm. Due to the angle of the holes in the orange piece and the angle of the stem itself I believe is what causes the stem to rotate. Because this device was dropped it messed up the length which you both figured out. That washer fix is very nice but remember now because of the smaller outlet between that washer and ball you may end up having to open it up and clean it out more frequently.
That was a genius fix thanks guys for your help
hello, nice video, i was always told for detergent and descaler product, if you put too much it is less efficient than respecting the mixing ratio. what do you think ?
Great handy video Vince. 👍
You've got me worried now - my one of these was reluctant to start spinning when I used it the other day. Something else to add to the list.
FWIW to me it looks like the angled hole plate makes the ball-bearing end of the nozzle rotate around the chamber. The small O-ring then contacts the side of the chamber and makes the nozzle spin on its axis, which in turn may make the output end run on a water bearing to reduce wear.
Informative video. Could you please tell me the size of the big and small O rings and also what is the 'plastic disc with holes' part called? And any links to purchasing the same. Thanks
Here is the way that helped me. The nozzle jammed and gave a straight stream, the pressure was ok. What I did: "I found a way to start the nozzle without disassembling it. Just squirt the lithium grease in the spray inside the nozzle from the outlet side. Lubricating even a wet nozzle makes it run like new. 20 minutes. Then you have to repeat it and the working time is longer. Fairy tale. I recommend it. I used CX80 Lithium lubricant. " My nozzle got a second life, after a few cycles with grease, I washed 350 square meters of the driveway. RECOMMEND
Thanks guys, VERY interesting video.
Great video guys. Thanks, in mine the problem seems to be with trigger gun. Any tips how to get into it? Have removed 3 screws but the rest seem to be some kind of plastic rivets??
Awesome video as always 👍🏻❤️
Brilliant job guys, helped me a lot
Well done mate!
Very nice deduction and repair. May I suggest that 1) I hope you used a stainless washer. and 2) If you had used a rotary fine grinder and created indents around the outside of the washer for water to bypass, you would have had a far better flow and cleaning pattern!
If you don't know what I mean, just ask.
Amazing solution, guys!
thanks to you sorted mine thanks keep up the videos good work and very enjoyable
Thank you. ! A great video. Answered all my questions!!😊
One thing i have learned years ago the hard way is, dont lend your tools to anyone.
in addition to that... if you borrow from someone return it in better condition than before
And don't borrow from anyone either go and buy or rent what you need and don't be offended when told to f*ck off.
Totally agree 💯👍🙌. Never lend.
When you ask for your stuff back. They have attitude and are ungrateful.
It never hurts to take stuff apart... It's already broken, and you may just learn something.
You either win some, or learn some.
*I haven't used it yet, however, this pressure washer replacement gun offers greater spray flexibility over the standard sprayer gun that came with my pressure washer originally.*
My problem with this wand was the tip. True the ball bearing does sink in, so the washer trick is good. The cure was the end tip has a hole in I, pushed the dirt through with a strong needle and voila that did it. Put it back together, don't forget the O ring and it worked like new. Thanks lads.
This is why UA-cam was invented for!!! Great video.
Hi mymatevince wow what an interesting video brilliant 👍
Thanks very much mate. Fixed mine a treat!
Vince tell your brother to get the patio head cleaner with bristles it cleans about a 10 inch circle from 4 inches away an stops the spray I haven't cleaned my drive/patio with just the jet since I got the head attachment an it cleans the area in a quarter of the time an your feet stay dry.
You also use less water.
The dirt blaster works better from a distance. The closer you go the smaller the cleaning area...
Good work on that washer 👍
If I look at the construction the ball bearing blocks the passages as it is in the top cavity of the small pipe(water inlet). Perhaps try putting the ball bearing next to the white pipe, this way the entrance is not closed of by the ball bearing. I had a similar problem with a ALDI topcraft/kingcraft one.(which was also kaercher) I that case the ball bearing went in the upper cavity to give enough inertia to the pipe. The water entrance was not in the top part but half way the length of the pipe.
great video as always
Hey vince hope and the family are doing well, i have a question i have a PS4 pro the optical audio went out i need to replace it is there any chance you could do a video on how to ? Thanks and great day everyone 👍🏻
I've been using that very same pressure washer to clean my car this morning haha
I had mine not starting after almost a year-stop. It would just not start as I pull the trigger, so I thought it was something with the switch. And so it was: not the main switch itself, but the pressure switch inside - it was stuck somehow. The problem was that in order to disassemble that switch I had to undo the pump's head. On reassembling it, I mounted the o-ring wrong and it leaked all the oil out. So I had to disassemble it again, do an oil change and finally reassemble the whole thing. Now it works flawlessly!
Vince why not buy whole broken Karcher unit? That would be cool video and maybe views also could raise.
There is a groove on that orange piece, and I'd wager that the o-ring is supposed to be around that rim when it goes back, rather than just sitting limply behind the orange disc.
Nice trial by error fix.
Question: metal ball bearing vrs plastic = worn plastic.
Metal ball bearing vrs metal washer = ? Will the coating come off either the bearing or washer and leave rusty jammed ball bearing?
Ideally you'd want to use a brass washer, and it should probably be modified a little bit, so that it still allows water to pass through freely.
that is not entirely true, some nylon types are so hard they wear through steel in no time.
We have the same Kärcher pressure washer and tips
Thanks so much for sharing.
Great work!
This is an excellent Video . You Know how to Teach..
Those Karcher systems are junk but the point is that it is now a working Karcher and not yet another land-filled Karcher. Great work.
I had 2 nilfisk ones they both broke after the year warrantee was up. So what make are worth having then?
I have two of these wands and I am on my third, The fault of the machine hunting caused me to throw away a perfect machine. I will try your fix but I am not sure if it will rust the washer and make it fail if it is left wet?
Brass washer.
I will check if i can print the perfect washer, thanks for the video :D
Can you do a video showing how to replace the end bit on the hose. The brass connector that goes into the machine/hand gun.
Paul: YES!
Fab little fix Vince.
Great Video, very informative ! HOWEVER, I can't for the Life of me, unscrew the Conical Bit. I've tried everything including carefully immersing the Conical Bit in boiling Water in order to expand the threaded (female ) portion from the threaded (male) portion on the Lance. At the Moment I'm soaking it in WD40 so I'll try again later. I see that you have a "K2" Version which is a slightly lower Pressure than my "K4". I was at the local DIY Center to find the Price of a new "Dirt Blaster" (as you call it) and they are quite reasonably priced (by Today's Standards). There were 4 different ones according to the Pressure Value of the High Pressure Machine. The Prices are considerably lower here in Germany compared with the U.K. (well, it is a German Company after all). I'm always amused by the way the Brits mispronounce German Words, but that's another Story.
Ask your Brother if he can suggest a better Method of unscrewing the Conical Bit. Failing that, I'll have to buy a new Lance - Yuk !
Use an "Oil filter wrench", along with the 18mm if needed! Might sound strange, but a multi hand 🖐 operation, will surely help that first break. Time for the "volunteers" step in! ;-)
Love the content Vince. Highlight of my YT week. Also love how right at the end of the video, you hit the very nozzle you'd been fixing onto the ground 🤔🤔😂
Thanks so much my friend’s very hep full
Hi where is it possible to buy the flat steel washer to fit inside the dirt blaster
Very good work👍🌹.
This is just a bad system, to be honest. I used to have a Karcher machine a few years ago, and the lance stopped spinning within just a couple hours of use, got it replaced, and the new one stopped after a couple weeks.
On my old Nilfisk (i'm guessing that's a brand you guys don't have), everything is still working fine after like 10+ years of use, even though it's a much cheaper, much more low end machine. Now i did like the Karcher a lot, apart from that awful spinning lance. Next time i need a new machine though, i'll probably just stick with Nilfisk.
Going to have to finish that patio off now vince 😄
Wondering if the washer will cause the bearing to corrode over time?
top tip ,one little washer, and mines perfect now . was going to splash out on a k4 , but get some more life out of mine .
Had same problem. Pulled the triangle off with hands. Soaked in vinigar for a few hours and it returned to life.
that was interesting, my one stopped spinning a while back guess that's another job for my social isolating todo list
Looks like mine have the same problem, I will check if I can fix.
Every time I hear your brother I imagine Iwan Rehon. And I'm here for that.
Hi sir ..where you bay this piece?????
Maybe it's possible to 3D print that plastic housing for the spinning steel ball because the steel washer may damage the ball over time?
Thanks for the post I have the same issue, another person put a very good comment , don't lend ur washer
The pressure did end up increasing....but you also changed machine sizes, very significant actually. Thats a no no boys, tut tut
