#38 is the pressure switch that has to turn the pump on and off when you release the trigger. Problem is, the switch is almost the price of the unit! It is a switch that can't be serviced, only replaced!

Hi, thanks for your reply. I have checked that side already and it's not the same cleaner as what I've got. I just don't get how my cleaner started the cycling problem, it was out of the blue. I rarely use it as it is for basic hobby cleaning.

It may be different, but your cleaner has same type pressure switch. Locate it and see if it can be removed and cleaned..Some pressure washers have a valve that moves up to trigger the switch.
