    I found the pack contained more than I required and have put them away for the future. Everything that was required was there with full visual instructions on fitting. Brilliant. Job done.

      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.

      It may be due to a split input connector see our video: Replacing the inlet and outlet connectors on a Karcher pressure washer http://www.espares.co.uk/advice/8/1166

      Any leak from the high pressure side of the washer will cause the motor to pulse. Replacing the cylinder head and seals is the most likely (but not only) reason for this problem.

  • Q Red 'O' Ring on hose to trigger connection 1 Answer

    The red 'O' ring seems to be very thin in comparison to the collar on the hose to trigger gun fitting and there is a lot of movement, is this correct?
