Brilliant guide. Most of these karchers are all the same once you crack them open. This is a great walk along.

Very good instructor - clear, concise and thorough. Thank you

Very clear description. Nicely done. It's helped my understand the inner components of my pressure washer.

Thinking I can repair my pressure washer myself after watching you excellent instructions. Thanks so much for posting this video

Great video, very informative, clear instructions, very professionally done! A+++

Brilhant video! Congratulations, the best guide i have ever seen!

Thanks for the video, HUGE help

Nicely done video! Great detailed information. I have the same washer but my issue is why my hose from the outlet valve keeps popping out of place whenever I release the trigger?

great video.. my karcher has a problem... starts one time but to restart take some time, up to five minutes. last week I notice that if I remove the water supply and reconnect to electricity starts to work again with out have to wait the 5 mins.

Very helpful, thx

This is the third kartcher washer in three years.im getting fed up with the constant falure ,i dont have the facilities for home repair i live in a isolated community with no means of local repair ,Get your act together kartcher

Grate video Mark and very helpful. When I disassembled it some oil dropped off and I want to replace it. Please tell me what type of oil shall I use

thanks for the great video! i tore my entire pressure washer down and greased everything. everything seems fine but i still have pressure issues. any idea?

Mark - great job and super-clear assembly/re-asembly. I replaced the manafold as it was leaking but i now have the same issue as Alan Shum commented. Everything looks good when re-assembled but i have poor pressure. You mentioned a pressure switch when aligned back the main switch underneath the chemical valve. Is there something i need to do there to get back pressure? Thx Gabriel

Awesome video really helpful!!I had a problem and i need your advice to solve it!I opened the pistons but not the way you did so the oil leaked off..Can i fill it with oil again or i damaged the machine?

Hi, thanks for the video, how much oil do i have to put in it? What density?

esta bien que el video sea para vender sus piezas pero tambien deberia explicar el funcionamiento de cada pieza de cada valvula, que funcion cumple en la maquina cada una de ellas y que porblema ocasiona cuando estas fallan. solo asi podremos darle u like y conteste las preguntas que le hacen como que aceite usar. gracias. this well the video is to sell their pieces but also should explain how each part of each valve , which meets function in the machine each and porblema caused when these fail. Only then can we give u like and answer the questions asked as to oil use.

thanks sir

I have a question if someone could answer please, were the pistons sit in the housing does the roller bearings run against the pistons or do the pistons just run around the washer and the bearings underneath the washer and then the ablong coupling that attaches to the crank shaft opening???

hello, i did the assembly but to try to turn the upper pulley by hand, seems to be locked, is this usual? Whereas before i could turn screw manually without problems. I can turn on the power grid for testing or have a problem? thanks

Super In my Karcher K4.98 the check valve beneath the chemical injection valve was broken. Could this cause the motor to stop as soon as I connect water to the washer or is the inlet check valve broken??

KArcher K6.91 - switch mechanism - I cannot seem to correctly relocate the spring which engages the internal switch, any diagrams you can direct me to?

Hey Just wanna Know What could Be The problem With My Karcher Pump K 4.91 It Works But Does Throw Water With Pressure. Thanks & Regards

My motor did not have Greece, when I took it apart, I had to wipe up a half cup of oil from the motor that fell onto the workbench.

Hi mate Excellent video. Great description and no music. Brilliant. I disassembled mine before looking at this. I have found a minute cracking in the chemical injector housing and so need to order a portion on the pump to replace I guess. My question is that with the hose attached I have no leek or very small. When the pump us turned on, it increases in pressure but not to the level you would expect to get when it's in use. Do I need to worry about all the valves etc. It's hard to understand why the small spring loaded pin that enters the electrical connector has no movement because the chemical calve when inserted shoves it to its maximum position. Is that correct. The cracking was caused by a friend not emptying during winter. Any help would be very appreciated. Thanks Tony By the way you forgot to connect the electric connection just prior to screwing down the pump assembly or can that be done afterwards on that model? Thanks again.

Quick question on the the area where the valves meet the motor plate - is this area meant to have oil in or grease. I've taken mine (K3.575) apart and its full of brown gooey stuff - so water has leaking into her, i just dont know what & in what quantity the replacement grease/oil should be.

How do you replace the oil, as it leaked out when I stripped down the pump.

can anyone help in relation assembling the plate spring on karcher pressure washer

hello only a question if you can help me.. how much oil takes the pump? and in a K4.98 (karcher) its the same level of oil? thank you

tengo uno que compre hace 7 meses el motor funciona bien pero tiene una fuga que impide usarlo correctamente

The cylinder where the springs are has oil/ grease type of fluid, but it looks a bit discoloured, as if it has water mixed with it. How much oil should it have, and what kind of oil/ grease/fluid ?

hello, what kind of silicone grease you use?

I watched your video and did exactly as shown. Well so I thought! Problem is once I turn on the water to start using, a dribble comes through until the pressure builds up, then nothing. No water comes through what so ever. What have I done wrong to get this situation?

From your description, you have 2 issues with the tool. The on/off switch sounds to be defective and should be checked. The not building pressure could result from a plug, defects or cracks in the pump or pistons or a defective pressure valve. Sometimes if the pressure washer is allowed to freeze with a small amount of water left inside it will cause damage to the internal workings or even cause the housing to crack. It's difficult to diagnose without seeing the tool .

Mine is leaking water from somewhere around the valve head or control head. It is while the water is on, but pressure is off/unplugged. Does anyone know which part has gone bad to cause this symptom? I don't want to just buy replacement parts until I know which I really need. Thank you!

Hi When i lifterd up the piston assembly then there was no oil in motor but there were some grease. Kärcher 4.99. But somehow I managed to spill some water in the motor (next tilted plate and bearings). I think it would be wise to clean it all up and add some grease (or should there be oil)?

+Andres L I would recommend cleaning the water out of the motor to avoid any short circuits. The electric motor have a small amount of grease not oil in them.

+michael coster Take a look at the pressure check valve and see if it is coming apart. Another thing to look at is if you're in a cold climate, check the pump for any cracks. Sometimes water remains in the pump of the winter. This can freeze and damage the pump.

Thank thank thank

carries oil or grease that machine and number of oil or grease ? 3.39 the minute you get a piece, that piece in the washer to repair k3.97 not far along as yours , jump and spring is removed , so is or should change this part

Can we connect a normal pvc pipe to the outlet in any manner? forget the amount of pressure coming out.

@FIXTechGuides

+Harikrishna C M You may be able to use the PVC Pipe. The pressure on these electric models is usually not as high as some gasoline models. My concern would be not the constant pressure but the low to high pressure surges that may cause a failure with the hard PVC pipe and fittings.

villijs33321 I read your question and felt I had to reply because I had a similar problem. I solved it by increasing the water pressure the the inlet of the washer. When water is used when rinsing for example it uses a higher volume than when using the shampoo or detergent. this seemed to fix it. Hope this helps.

You forgot to mention the oil in the pump. What type of oil and how much to use.

How much oil goes into the pump 2.0 K? And the quality ?? Engine oil, hydraulic oil?

Hi Jess, unfortunately at this time we are unable to offer technical support. I would suggest contacting the manufacture for further information. I sincerely apologize.

The thread has worn on the connector of piston control head cover meaning the outlet elbow no longer locks on and water leaks when the washer is powered up. Any idea why this has happened?

+Patrick Chinedu I believe you're referring to the quick connect the wand hose connects to on the pump. Correct? The Ball your see in the fitting can sometimes become stuck if the pump sets for a while. Hook the hose up to it and gently tap it before you start the motor. If that doesn't loosen it you can take if off from the pressure washer, tip it on it's end and put some spray lubricant in both sides and let it soak. These are also available on our site if it is bound too tightly.

I haven't been able to locate a parts list for a K2.400 so here are 2 options that might help. 1) Karcher does have a K2.40D. The chemical injector for this model is no longer offered by the manufacturer. 2) Karcher model K2400. The chemical injector info is at the following link: www.ereplacementparts.com/spare-parts-kit-p-482334.html
