    Karcher could not help me identify the 'O' ring kit I required which I managed to find through Espares. Although Espares could not help me technically, I did manage to scroll through their spare parts list and eventually found what I was looking for. The kit arrived very quickly and was reasonably priced.

    I bought these because I need one O ring but didn't really know what size I needed. This kit covers everything so I now have loads of spares.

      Hi Crippen sounds like you have a fracture in the control head as I did, this opens when the machine builds up presure and then releases it through the fracture, it is likely the fracture is under the metal head plate used to secure the unit head hence you cant see it, I know your post is long ago but this may help others as when I read the posts on the espares site it was no end of help to me. If the seals are ok on everything else I suggest replacing the control head housing.

  • Q Permanent Leaking To Chemical Discharge Bottle 1 Answer

    The Chemical Discharge bottle will continue to fill up without any power on and then stops as the pump uses the water with power. I reckon it is probably a valve maybe that feeds the clear plastic pipe. Can you advise please which part /valve requires replacing. Mine is a K6.50Mb unit.

  • Q Karcher 2.94 m Pressure Washer Leaking 1 Answer

    Hi, I asked a question on here about 3 or 4 months ago, as having not used my pressure washer for some months it had started leaking. It made a rattling noise when I moved it. It was suggested the fault might be the O Rings. I have a Karcher extension hose between the front of the unit and the pressure gun. That has seized onto the pressure washer, and however hard i try i cannot shift it. As a result I hadn't got round to stripping the washer. Today I finally got round to trying to sort it. Two issues: 1. I cannot shift the hose from the washer. Any tricks to loosen this please (I have tried squirting GT40 in there, but it is not loosening); and 2. I opened the back off the machine. The noise is two screws about 9mm long and heads about 16-17mm wide rattling around inside. The motor and internal bits are not attached to the case in any way. Any idea where these screws are from, and is the motor supposed to be attached to the case. Do you still thing this is the O-Rings? Thanks for your help, Stuart

      The motor appears to be clamped by the upper and lower cases and doesn't appear to have any fixing screws. To remove the hose try heating with a hair dryer to expand and soften the hose screw fixing.

  • Q leaking k2 only when in operation 1 Answer

    I have a k2 411A washer which leaks and pulses only when the trigger is operated. 1) is it worth fixing? 2)where can I get the parts in the u.k? details are also... NR. 189164 K2 (1.994-972) 441198 19949720189164 I hope you can help Thanks Ashley

      The pulsing is due to the leak allowing the pressure to escape. Disconnect and remove the case then just connect the water to the unit to identify where the leak is occurring. We can supply the parts once identified.

      If there is always low pressure and no leaks the problem is likely to be worn seals or a stuck valve.
