SOURCE: karcher k7.80 pressure washr
I have a Karcher K 3.86 M electric PW with a similar problem: water leaks from the pump near the outlet and the pressure surges on and off continuously at intervals of 1-2 seconds. The leak appears to be coming from a very thin crack in the plastic pump head in what I think is the "unloader" valve portion. I read elsewhere that if you leave water in these PW's and it freezes it will crack, causing leaks. I don't know how you can empty all the water out so I think we must store these PW's in areas that won't freeze in winter.

Hi, Karcher calls the unloader valve a spill valve,
this is a link to a full drawing/parts listing , and your fault description might well be a sticking /seized unloader(spill ) valve hope this helps
the part number is on page 9 of the drawing
spill valve 45910400
hope this helps , we usually use some good quality silicone grease to lube the valve ,

Yes, the water should be turned on first but if it only ran for a minute or two it should be OK. Most late model pressure washers have an automatic shutoff when the trigger on the wand is released. Turn on the water and then the machine and then squeeze the trigger on the handle of the wand and the motor should start as soon as the air is cleared from the line by the flowing water (about 10 seconds). If the unit was put away wet last season you may need to clean the nozzle with a piece of wire too.
