Trying to FIX: Karcher Dirt Blaster Lance NOT Spinning

[@StuMazza180]

I love watching investigative fixes! Great work gents.

[@GadgetUK164]

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.

[@ThomasMTube]

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

[@frankwyllemet]

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

[@hanwachtel]

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?

[@frankwyllemet]

@@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.

[@chrismechanic2000]

so why dont they just give us a brass one then ffs 0.0.

[@PatricioGarcia1973]

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.👍

[@chrismechanic2000]

i suppose you have that silly auto gearbox problem...

[@Catstorm99]

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.

[@helpinghand7080]

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.

[@vjary8142]

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.

[@AbdulHakim-uq1nv]

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.

[@TechGorilla1987]

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!

[@ThStg]

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!!!

[@999shakers]

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)

[@TheSweeney-UK]

I didn’t have any tiny washers so I was putting some raw plugs away and came up with the idea of slicing a neat piece the size of the washer that you used and it works a treat .

[@mangkukX]

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.

Very Impressed the way you and your brother worked it out .

[@كنمعاللهولاتبالي-ه1ش]

[@ericsimmons4962]

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.

[@jurajkrajcik4410]

Thank you . I am experiencing this issue at the moment so this knowledge is a good way how to start fixing mine Kärcher.

[@brianmarkie4667]

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.

[@diemaschinedieviereckigeei2941]

Thank you, Vince & brother, that really helped me!

[@rgqwerty63]

What a coincidence, I literally set my karcher blaster up earlier today and I come on youtube and this video is waiting for me

[@malekdahou95]

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!

[@justpassingthruuu]

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.

[@alialtraouti6418]

Excellent trouble shooting. It is very useful to me. Thanks guys.

[@jeremydewolfe8026]

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!

[@inspireality]

Nice fix!!... from one Karcher repair person to another. I will try the washer fix on my rotary wand. cheers!

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.

[@colinknowles1644]

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

[@customengravingsbyhuntersh657]

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 🤷‍♂️

[@polishlocks]

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

[@coll6]

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.

[@And-rc9yy]

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.

[@999shakers]

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!!!

[@And-rc9yy]

[@thepfunk360]

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.

Great job guys, I have the same issue and will have a go at this

[@Graham_Langley]

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.

[@DEmma1972]

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?

[@BeerBellyDK]

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.

[@chrismechanic2000]

that is not entirely true, some nylon types are so hard they wear through steel in no time.

[@Gixxer983]

One thing i have learned years ago the hard way is, dont lend your tools to anyone.

[@snowgroomer]

in addition to that... if you borrow from someone return it in better condition than before

[@Blagger3000]

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.

[@sabazeeshan1391]

Totally agree 💯👍🙌. Never lend. When you ask for your stuff back. They have attitude and are ungrateful.

[@ThomasWinders]

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!

[@trkmathur]

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

[@joannapocock6055]

Great informative video ,thanks for sharing it with us . I am having a problem with my patio cleaner not working .

[@BeerBellyDK]

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.

[@paulfox89]

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:)

[@Lezmila]

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.

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.

[@charleshines2142]

Make sure to use a stainless steel washer so it lasts. One will not be horribly expensive. Also most washers are made with automated punches and may have a bit of a sharp edge on one side and the other side will have more rounded and not sharp edges. Make sure to put the slightly sharp side so that the bearing is not rubbing on it. These nozzles are not overly expensive if you shop around but you don't really have to if it is not worn out or broken.

[@gartenfreude796]

Amazing solution, guys!

[@lisab3396]

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.

[@fungunfanatic]

[@matthijsverweijmeren6114]

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.

[@nicholassiminson1825]

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! ;-)
