Disconnect the wand from the washer if you get water coming out of the discharge, the problem is in your wand or the line is plugged going to the wand.

There is a spring in there that makes it recoil. It has probably broken. Depending on who made the engine you can get a replacement for the whole assembly. A small engine shop should be able to replace it for a not a lot of money.

The pump will cycle on/off but if it works properly when you pull the trigger and it keeps working then its working correctly.

Remove the fittings and check the internal screens, probably rusted and or clogged.

Im currious what on a pressure washer required "cleaning" what were you running thru it other than water ?

do you think you might have dissasembled something on engine part and might not have assembled it back quite right?

Will any user manual serve, or do you have something more specific in mind?

WHATDO I DO

The female hos bib connection should have a typical hose washer inside.Often you can't tighten the nut tight enough without this washer, to keep it from leaking both from the hose, and the rest fo the fitting into the washer.
