I am having a problem with my pressure washer which has been getting progressively worse. When you first pressed the trigger, the spray jet pulses as the motor goes on and off. After a little while of keeping the trigger pressed it runs continuously as normal. If you let go of the trigger and then press it again, this cycle starts again. The time between pressing the trigger and the unit operating normally has been getting longer and longer.
Does anybody have any idea what might be causing this?
