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


Any leaks from connection at pump to gun and wand assembly if so the valve is detecting leakage and open up again without u squeezing trigger it builds up in the head.if your trigger gun is leaking internally then you will need to replace the gun thi ... Pressure Washers

I have a Craftsman power washer model 580 752020. When I start it up, turn on the switch the electric motor runs fine until I either close the trigger to the spray nozzle or press the trigger for power spray. The electric motor just shuts down, if I take my finger off the pressure and let the water run with no presssure the motor runs fine. My question is this. Is the capasitator on the electric motor the probable cause and is there a way to check out the capasitator to see if it is malfuncti


I doubt that it has anything to do with the capacitor on the motor. i think you are having a problem with the actual Motor Drive circuitry. What is happening is when you close the switch, this tells the Motor to "Ramp Up" to pump the water out, what ... Craftsman Pressure Washers

My pressure washer starts fine, shoots water OK. After running for 5-10 minutes cleaning siding I shut off machine. I go to start it again within a minute or two and the thing feels like it's just about seized. If i wait until the motor is completely cool, it will pull start freely and start right up. I think something is wrong with the pump, not the engine.

Karcher K2.36 Pressure Washer I've just fired up my Karcher for the first time since last year and the motor started running fine, I then switched on the tap to allow the water through and the motor cut out. Now it won't restart, any ideas? I'm wondering whether the water supply should have been on before I switched the motor on but it's too late now! Help!

Hi- I have a Simoniz S1600 pressure washer. Usually when I start it, the motor kicks in to build up pressure. Now it won't kick in no matter what I do. A small stream of water will come out but there is no pressure. There are no reset buttons on the exterior of the machine. Thanks so much.

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.

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
