generac power washer
I have a generac mod 01439-0 power washer, 6 hp briggs, 2100 psi/2.0 gpm. When I initially start it I have high pressure through the wand. If I release the trigger and reapply it, the pressure drops to low and will not return to high unless I shut the unit down and restart it. The engine runs good and as long as I keep the trigger depressed the pump seems to hold high pressure. I have checked all the filters, screens and lines and all seem to be clear of obstructions.
