... Pressure Washers

I have a Husky gasoline pressure washer. The honda motor starts but stalls because the pressure by-pass (not the right term) doesn't seem to open and builds up pressure. I haven't tried to remove any parts yet. I think grit has got in but don't know for sure. The pump looks pretty simple and the part I want to remove for cleaning looks like a plastic hexagon nob. Will this access the by-pass or is it something else.


I think you're right about the knob, but try this:Open the water to the washer. Leave the line open, and hold the trigger down to get all of the air out of the supply and discharge lines. While still holding the trigger down on the spray gun, ... Pressure Washers

I have a McCulloch FH160B power washer and it no longer builds up pressure. I haven't used this very much at all. I tore it apart and cleaned everything I could find. When i pull the trigger for the spray nozzle, I get line water pressure. When I release the trigger, the power washer sounds like it starts to build up pressure. When this was working correctly, the pump would shut off when the trigger was released. Any suggestions?

Pressure Washer I have a Porter Cable pressure model no.PCH2401.It works fine for 5 minutes,then I can hear the motor loading down and then it stalls out. I tried to start it and it was very hard to pull on. disconnected the water supply and if was very easy to pull and started right up. I noticed the pump was very hot.This unit has a thermal relief valve on it,shouldn't it have released when it gets to a certain temperature .I was thinking maybe this is why it might be shutting the motor

My powerwasher(2500psi) with a B&S QUANTUM 120000 gas motor will stall when hot, pressure drops significantly, and is hard to restart. When it does re-start, it stalls again in 2 minutes. This behavior started recently after working fine for 2 days. I changed the oil-no difference.


I assume you did plug and filter change. Check the plug wire for fire when hot or problem occurs; it should be pretty visible- don't shoch yourself. Check that fuel is reaching carb, check tank for debris. You may need to have valve adjusted. G ... Pressure Washers

No pressure Gas powered pump is a radial type from DeVilbiss. There is very low pressure, although there is some pulsing from the pumping action. There are no leaks and the supply pressure is good. Pump pistons are in good condition. They seem to be pumping when I had it disassembled and operated by hand. I suspect it is something in the bypass or unloader. Or it may be in the ''easy start'' assembly which I assume reduces backpressure on the pump when starting the engine. Pump has a temperatu

Asko Dishwasher starts the cycle by pumping out as it should. But does not stop pumping nor advances. If I click it forward manually it starts to fill and then before overfilling goes into pump out without washing then just repeats this.
