    Saved buying a new "Pressure washer".

    Customer asked if I could dispose of their broken "Pressure washer" and buy them a new one. I could see visually what was damaged. Took it apart carefully. looked on espares, found a matching part. Put it back together and saved a the customer some money which is now going to be spent on other broken and worn out electrical items. Every ones a winner.

    Perfect product for 20 year old model

    This fitted my 20 year old Karcher 380 model one and returned it to working order. The email help function worked to identify the correct part and that part works fine. The Video 'How to Guide' only covers more modern models and with the old ones there are 4 Allen bolts that need to be removed before you press out the pressure head from the metal cup moulding. This was the correct part and it arrived in 48 hours.

your video on how to fit shows the engineer removing a clip. This clip is not on my washer a K3.99M, how do I fit the assembly

  • I cannot find the release clip for the Inlet Elbow on my K4.99, do I need to try something else? By Barrie - Norwich - 02 May 2011

    Hi bert, the inlet fits in the same was as the video above, but rather than a clamp holding it in to place, the cover acts as the clamp.

    Hi, Here is a short video on our website showing how to remove the Inlet and Outlet Connector on a Karcher 3 series. However the process should be fairly similar.
