pressure washer troubleshooting image

I just bought a pressure washer and the motor runs but when I press the trigger on the gun nothing happens. It is an electric 1500psi pressure washer, very cheap. Has anyone come across this problem before?

CHECK FOR LOW WATER PRESSURE OR RESTRICTED FLOW AT INPUT. THIS WILL CAUSE A FLIMSY HOSE TO COLLAPSE AND CUT OFF THE WATER TO THE MACHINE. WHEN YOU SHUT THE MACHINE DOWN TO TROUBLESHOOT, THE HOSE EXPANDS AND LOOKS GOOD AND FOOLS YOU SO YOU CAN'T FIND THE PROBLEM.

Water Pressure Regulator going bad?
Susan O
About every couple days I turn the shower on or the faucet on and fine no water coming out. If I tap on my water pressure regulator I hear a hiss and the water pressure comes back in full. Why does this happen every couple days? Is there an adjustment or should it be replaced? Thanks

Sounds like the screen (filter) in your PRV is clogged. You can definitely take it apart and clean or replace parts but it's really not worth doing that unless it's a larger PRV. You can get a new 3/4" PRV for less than a hundred bucks. I say it's not worth it because you can open up a can of worms trying to repair it ie. finding parts, washers bad, bolts hard to remove etc. Next thing you know you have no water or have to bypass the PRV till the parts show up.
A licensed plumber will charge anywhere between $250 to $500 to replace this, that is with him coming out troubleshooting it, going and getting the parts, returning and installing.
You could save money by supplying all the parts yourself but most plumbers won't guarantee parts supplied by the customer.
You could try doing it yourself with a combination of threaded fittings and unions. Just make sure when you order the valve that you order unions with IP threads. Don't use pipe dope on the union gaskets.
