Thanks for taking the time to upload.. saved me replacing the entire washer when all I needed was a cylinder head.

June 30, 2019 Two days in the freezer worked. First used a screw driver as suggested in video. Loosen nicely. Finished by putting a wood dowel in the output and tapped lightly. That had the black nylon cartridge Cooke out of the metal cage very easily. Thanks for a very accurate video!

Your first advice, within the first minute, saved me from taking this unit apart!!! Thanks

Thank you thank you thank you! I just followed your instructions re the Karcher being flooded and it worked! I'm so pleased! Thanks again!

Well done video! Very descriptive and thorough, demonstrating the potential problems in the video is a good idea. Thanks, Nick! Mine had the cycling problem. Checked the inlet filter and found it had residue. Flushed it clean and problem solved! No need to tear my machine apart. Glad you mentioned that bit early on in the video, saved me lots of time and un-necessary work. Mine is many years old, had good use, and this is the first problem. Never knew there was a filter! Easy fix. I disagree with those who say that it's a poor product. For occasional home use, can't be beat for the price/performance.

Thanks for posting this - very helpful and beats having to buy a new unit.. Cheers!

Many thanks for a great video, got my kartcher working after clearing air block.

i just performed the first step of bleeding it and it worked , thanks champion , i found the karcher on a building site i was cleaning up , under a pile of weeds and temporary fencing and was pretty sure it was fucked but it works , you beauty

Thank you! Running the water through it was all it needed!

The best explanation, no doubt... Thank you, nice and clear

Tried your bleeding on my karcher and wow it worked straight away great stuff

He is absolutely right - if pulsing is the only prob bleed as I instructed here .

Thanks, fixed mine by clearing the air out👍🏼

Hi Nick, you ever heard of a unit just starts and stops. If I work with the unit is fine...but when I stop it starts giving off sound like starting stopping, and no pressure and water comes out unless I turn the unit off and than back on....I will try making a video next time I use it

good vid... the rubber seal is common with bathroom faucet knobs.

i bleed the system and it worked!

Well done for keeping absolutely everything out of shot

awesome video man, keep up the good work!

Much appreciated...very helpful instructions

Good news for me, I bled the pump for a minute like you said. Solved my problem!! thanks for the good info

THank you buddy was got to send my k5.540 in to get fix have was 30 cars with it and shut down ( as you tell to do air lock it was) Thank so much in no mans land for help out here LOL Thank you

Other than getting the hose connector turned around (watch out for that one), the machine is simple to put together and use kzfaq.infoUgkxfQauTxLT0JLSvqkq10rD79TU4k0Vz8zP . And very nice, too. I'm surprised at the power-it's more than we'll ever need, and we've not even used the most powerful setting yet.I've cleaned off a dirty concrete porch to get it ready for sealing, started to clean siding, and I know this pressure washer will be terrific for cleaning tools this fall.The only issue we had is we had turned around the hose connector, and it leaked. Once it was on correctly, though, we had no problems with the connection. Just remember that the end with the green knob goes towards the hose. It's obvious now what we did wrong, but not necessarily obvious at the time.

Great video on the power washer. My power washer does not want to turn on. I hear noise but doesn’t want to turn on.

i think it works like this say karcher has 2 types for example. 1 with plastic internal parts and 1 with metal internal parts. the metal one is stronger and can last for longer periods of time without cracking or melting in industrial use. but it will rust and stop working after EG 4year. the plastic one will not rust and will last longer then 4years. but will wrack or melt easily after EG 15mins of continues use.

Actually I answered myself. My pressure washer is a Kingcraft which is an exact copy of Karcher K5. It had no pressure at the gun and constantly turned on and off when the trigger is released. I have put it apart and ordered new sealings from my local car parts shop - 3 x 12x20x5 high pressure sealings for water and 3 x 12x20x4/5 for oil. The original oil sealing is 12x20x4/6, but I couldn't find it anywhere so I ordered them with 1mm less oil washer which I think is going to work fine.

Hi Nick,i have a Karcher K 2.59 and i disassembled it to replace the three seals because it had oil leakage.Well,i want to ask you how much oil should i put in it.

hi, I think its more got to do with your pressure sensor (unloader valve), lets just say eg.. the pressure sensor turns off power when the water hits 200psi. when you turn on the power for the first time the water will billed up to 200psi then will turn off. when you hold down the trigger the water pressure is at 100psi the motor is running at 100% and can't pump water faster to get to the 200psi so it dose not shut off.

1# unloader valve. take apart the unit, follow the detergent tube, on the opposite end of the valve where it connects there will be a valve. take off the valve and clean it and the bore 2# your gun might be blocked and therefore it hits the 200 psi when runing and shuts off (alot more pressure is on mist) pull apart your trigger and see if its blocked

First thank you, for your introduction. I first tried to bleed it, darn if it didn't work, came back and listened again. I had to slow the video down for me, and listen three times. 'Turn it off; turn the water on a minute, and take the power wand off. and let the water flow!' [a reading note may have helped me]. I talked to myself on the way to the garden. I thought I was going to get blown by the water, but assured myself; "it is turned off." Okay, you can laugh at me! None of their attachment areas are user friendly and I have the hardest time just turning mine [K3] on/off with the recessed design. The hose attachment is most difficult, as I always have to twist the hose to get the hose on, as their connector hardly turns in the direction needed; even in warmer weather. Now for the power wand...I had to turn my unit on its back and push all of my weight to put it using the spring system; difficult taking it off, but I did it! I don't have man's hands!After I did as you said, as I had my 'mantra' going; IT WORKED, but it did cut off again. I had read at the Karcher site, prior to finding yours, that humidity and an electrical power supply could cause it to shut off, but I left it for 30 minutes as suggested, and checked all GFI units; all outlets worked, but their suggestion did nothing. I did the same as you suggested; the same steps and VICTORY, it was great, so YOU ARE THE MAN! It has been working well today, with only problems with the hose kinks, but I realized my location is what is causing most of the issue. I am on a ladder cleaning gutters, and I don't have my unit elevated enough/ I am not brave enough to be on the hot roof. I am using the wand horizontally, consequently the 1600 PSI is not powerful enough to go one story up. I have been stopping and spraying down every now and then, so as not to repeat yesterday's issue...cannot thank you enough.I have a smaller unit in the basement that I got repaired here in Rockford for $40, and it took a long time, so by the end of the season, I just stored it. I should have tested it, because it didn't work at all. the serviceman said, "you got trash in the wand!" Yeah, right! This town is famous for just what happened there, so I try to fix things myself, so tired of being scammed and ripped off! I will try this method on the other... Again Thank You!

yes it does sound like a seal problem, did find them to be cracked. if that doesn't fix your problem check the control head or cylinder head for cracks. sound like you have it under control, let me know how you went with your seal price wise to save people money. thanks

Karcher 670 m Switch cover replacing. I am finding it difficult to replace this cover correctly so it will allow the relay to operate to switch on.

Nick, great video. I no longer have pressure on my K395. I did have a water leak and replaced the 3 grooved rings/washers in the cylinder head. Now I have no leak, but still no pressure either. Should I replace the whole Cylinder head?

Lots of hassle...well done for making the video 👍🏻

gracias por tu comentario tiene una Feliz Navidad :)

top video, cheers bruz

hi bitealarm do you mean control head and cylinder head? if you can see if you can see exactly where its leaking from, hose connects (new seals or plumber tap (i have used)), seals where the control head and cylinder head meet (change the seals), or a crack in the plastic of control head and cylinder head (you will need to buy a new one $30). if it not coming from the hose connects and dont want the hustle just change the control head and cylinder head for $50 then it will be like new. power too

Hi Nick. My Karcher unit keeps blowing the lance hose off. Both male (unit end) and female (lance hose) connections are plastic. Is there a fix for this?

the on off switch isnt working can it be replaced on karcher k2.99

A mi tambien me parece bien explicado

It seems like a.d.d is running rampid all over Australia these days.. Thank you for the videos.

hi, can you explain to me what your karcher is doing thanks

I am having a problem with mine. when you initially turn it on if you are holding the trigger it will work and have pressure. When you stop spraying it cycles off and will never start up again unless you cycle the power off and then back off then it will work as long as you keep the trigger pulled again.

Thank you... now to get the part. : )

So after spending aprox. $5 for sealings (which turned out to be just like the original karchers. don't know why they want $30 for them...) I discovered that the head has a tiny crack. I gave it a thought and it turned out that I don't have any glue strong enough to fix it but I have an idea of where to find someone who can fix it. For the DIY enthusiasts - search for sealings at SKF dealers or places where they sell similar replacement sealings, joints, etc.

I couldn't exactly catch which is the defective part - the plastic rings ot the rubber sealings. I have a broken karcher 5.something with exactly the same problem. I am currently waiting for duplicates of the plastic rings but made out of aluminum. I made some research and found out that the rubber sealing are not standard. Do you know if they are available to buy somewhere. p.s. Thanks for the "how to". It's very usefull.

Good video: thanks, and one question: is it possible for the head to be so badly compromised that there is almost NO pressure, with water (virtually all the water supplied by the intake hose) pouring out of the bottom of the unit? I have a different model but I think it is identical inside its casing.

Got a new cylinder head, didnt help, found a tiny difficult to see micro crack in the control head, away to order a part for it, thanks for the helpful video! Anyone looking for the cracks, quick tip, smear a small bit of copper grease over the control head and they seem to show up easier.

what do you do if its just on all the time and the motor sparks?

Maybe, but I have had my Simoniz S2000 for over a year now and no issues and much better performance than the Karchers at a lower price. Also carries a 2-year warranty as opposed to Karcher's 12 months.

nice thx man!

Hi there. Can you tell me what tool is required to remove cover of K2. Also where can I acquire from. Thanks.

Hi, my B203 has stopped working. Thought it was capacitor, but that's fine. I found if i have the hose connected with it turned off, then have the trigger depresses at the same time as turning it in it works, but as soon as you stop squeezing trigger it stops working again! Any advice? TIA

I've changed the cylinder head as I had low pressure ( but no pulsing ) and I still have the low pressure problem any ideas what else I can change?

Very interesting vid, thanks. I have a K5.50 which had been fine until today when it started pulsing and was under-pressure, then suddenly stopped altogether. Is the motor burnt out or something - repairable at all? New motor is stupid money :(

Im so glad I found this vid. this is great keep them coming.

any ideas? Karcher K 2.68 M It sprays but its seems like its on low pressure versus full blast pressure regardless whether or not I'm squeezing trigger

My electric Karcher power washer has no pressure behind the water when you squeeze the lever on the wand. How do I troubleshoot and repair that? Where do you get parts for Karcher power washers?

Handy video - but the problem with my Karcher is that it seems to be fine when using the normal spray head and water comes out of the release gun. However with a new dirtblaster attachment fitted, nothing happens. No water is released. What is the problem?

Those little seals are called o-rings if they are completely round in every way. If they are not, then they are called seals:)

how many times has this happened or when. did you get water on the unit and is it petrol? or electric. if petrol it could be just running rich and will blow white smoke, in time it will dirty the plug. 2 or 4 stroke

Hi mate,I have one of those units but model down on what youre playing with in the video. Mine is working ok for 5 minutes then just stops till almost cools down for a few minutes and then comes back online. Then itll do the same again.....What do you think is wrong with it? Cheers

thanks :)

I brought my second hand on Buy sway. The gun was leaking, the found a gun replacement for sale and it 2orked great. I went to use it today it woked for 2 secound the no power :(

What number hex fitting is used to disassemble the unit please?

Hi nick, replaced my cracked piston seals, part no 6362875 if this helps you next time. Machine is still pulsing. Fixed a leak on the outlet pipe with a homemade washer, still pulsing. Found i am missing part no 9.001-107.0 (cage), would this cause it to pulse still as no water leaks visible now?

Hi how do I test the motor itself I have checked all wiring and cap all ok but I can't get into motor any way of checking it from power socket any help would appreciate cheers

Mine won’t suck in water and makes a really loud sound. Any fix or do I need a replacement?

I have a K3.48M model. It works fine as long as I keep the fingers on the nozzle trigger. Every time I let it go, pressure washer never comes back on, until I remove the nuzzle ( end section of the wand),than pull the trigger water comes out freely, connected the nuzzle back and power washers works fine again, until I let go the trigger, same process over and over, very frustrating. HELP PLEASE!!

I have karcher k2 compact having 2 problem 1. water leakage 2. not taking continuously pressure water

hi nick,i have a karcher k 3.575, i found it leaking from the outlet, when i took off the front cover and turned on the water,i seen water coming from the top of the impeller/pump, any ideas. thanks

hey Nick, my Karcher K3.550 has no power. What parts do I need to check to fix it? Thanks

sorry, there are lots of different grades of oil used in lots of diffrent pressure washers. contact karcher with your model and they will help u. OR if not most pressure washer use SAE30 its a Non detergent, non foaming, rust protection and oxidation protection. change every 3 months or at 500 hr. i change mine every 3 years :) oil is more then the pressure washer

Hey I have a Karcher K5.68 2000 psi pressure washer and there is a leak at the input, any idea how to fix this?

No water coming out on the gun, how to fix it, thank u

My comment was lost somewhere si I am going to ask again. Is the problem in the oil seal spacers (the little plastic rings) or in the rubber sealings?

I have the 3.86 but do not have the right screw hex driver to remove the outer case. Can you tell me the size of the torx bit to remove the screws for the case? Thanks

my karcher is leaking but not pulsating. just constantly trying to build up pressure. any ideas?

Hi, around at point 4min20sec You mention shortly about "a litlle thing" and "you know you have done that" I think I have done this mistake but I simply can't make it right. Could You elaborate a bit more ? Thanks!

what is the problem when unit start but stop after few minutes of use?

τι ειδους λάδι μπορούμε να συμπληρώσουμε; Τι είναι αυτό το γκρι μέσα; Ευχαριστώ

mine K2.900 the water spiral jet doesnt work. Water spray straight only. Anyone can help. Thank you

hi nick my Karcher 320M has an issue. when i start the washer it works fine, but when you release the trigger it wont shut off. i have just changed the 3 grooved rings because pf an internal leak. So that is corrected now. No leaks. But still runs constantly. Any ideas? Thank you

i have white smoke coming out.... pressure seems fine any suggestions

the problem with my washer is full power range ... i can turn my spray wand up to about 60% pressure where its almost to a straight line before it cuts off ... i cant reach the mist spray .. soon as u twist the wand back down it comes back on .... is this a problem with my pump seals or just air inside the pump not being released because i noticed the pressure build up once i first used it i couldnt unplug the front quick release valve becuz i still had water in the gun

yes, I also have a GNC much better, strong and cheaper. sorry i said all of that its so i don't get sued by karcher.

Hi nick, cheers for the great video, helping me as mine was leaking. Taking it apart like your video, got to the part at 8.03 where the spring pops out of the control head, i had a look at a diagram here for mine, ransomspares.co.uk/diagram/karcher/pressure-washer-spares/483361/kb403-wb%20gb%20%281.423-356.0%29/ I cant see part no 35 (cage complete)? Does it pop out with the spring? Cant see in the video. Any ideas? Also found the seals cracked in the cylinder head, spot on!

can you plzz help mine has just died i tryed to run water through nothen happing

I have a k3.68m and it won't spray. It comes on but won't spray

Does anybody read this stuff? Is there not a simple rubber kit available by Karch OEM or aftermarket?

I have a karcher k2.54m washer and when I plug it in it just keeps pumping continuously without the water being connected or the hose. Can you help with any suggestions what it could be?

I have gotten t hose tangled when I was winding it up . does anyone have any words of wisdom. its t fathers in law.

40000 view 66 thumb but 1 friend thanks bro

Thank you for the video. question? My Karcher K392 is damaged by me. I made the mistake of putting bleach into the detergent reservoir. I didn't know better at the time. Now, water squirts out of the small tube that should be drawing detergent in. What parts do you think I need to replace and where can I purchase them? Thanks :)

39.318 view only 66 thumb? where the love?

Where do I find the screw driver to take it apart

i just boughr a karcher k2 plus... and its really straight forward to put together but the ptessure is really really bad... like pathetic.... i will do as this suggests but i bought this today snd if it doenst work i will takr it back.... this has zero power... my normal hose with a hose fittinf has far more power than this thing....

my spinning brush is'nt spinninig fast *powerful

The easiest way to fix these, is to take them to your local road train assembly area & have them run over it.

I would say the head is faulty if u have warinty use it if not open it up and have a look, kzfaq.info/get/bejne/iKp1gJihmMvIlIk.html
