Having problems with your Karcher 2500 PSI Pressure Washer ?

Hi:
This sounds like the bypass valve is stuck. You need to get at it and pull it out. Then check it for o-ring damage and be sure you lube it with a good waterproof grease before replacing. If THIS is your pump then the bypass valve is #8 on page 2.4

I have a McCulloch FH160B power washer and it no longer builds up pressure. I haven't used this very much at all. I tore it apart and cleaned everything I could find. When i pull the trigger for the spray nozzle, I get line water pressure. When I release the trigger, the power washer sounds like it starts to build up pressure.

When I use my Karcher pressure washer it works perfectly until I release the trigger. Instead of remaining silent until I pull the trigger again the motor intermittently, at approx 2/3 second intervals, starts and stops. Could you please advise what is causing this to happen please.
