I have a Karcher K4 premium ecologic leaking water.

It leaks when the pressure washer is off but tap on a little, and a lot when the pump is on but does not pulse. Is this the cylinder head?

    The problem is likely to be a cracked cylinder head. If you dismantle it you should be able to see the crack.

  • I've removed the covers. Looks like it's under the metal cap covering the white control unit, leaking like a sieve. Take it this means washers and or cylinder head? By A.H - Crowthorne - 23 February 2016

    Disconnect the power and remove the covers then just connect the water supply only to identify the area of the leak.
