Pressure washer acting backwards?
I have a Troy-Bilt pressure washer with a B&S engine I was given last year by a family member. The engine runs fine no problem and it’s had strong pressure until today.
For some reason it’s not pressurizing when I press the trigger, yet it will pressurize when the trigger is not pressed. To put it another way, engine ramped up and water is spraying out the release valve, until I squeeze the trigger then it just idles and water just flows out the gun like it’s coming out of a normal hose pipe.
It’s like it’s running “backwards” - it should idle normally then ramp up and pressurize when the trigger is pressed. I never unhook the hose going to the gun, only the inlet hose from my house, so it’s not hooked up backwards. Has the pump gone bad?
