My pressure washer motor won't come on. I plugged it in and it came on. I switched the plug to an extention cord and now it won't work at all.

Any other symptoms?

What is your model #?

Don't add an extention cord to an extention cord! Buy a 100' 14/4 extension cord and tie the end to the fence so it won't come un plugged.
If the plug keeps popping out of the short cord at the blower,wrap the cord around the handle to prevent disconnection.

User Control and Display Board If the washer won't start, the user control and display board may be defective. Check for power to the washer first.

Timer If the washer won't start the timer might be defective. This part is often misdiagnosed, check other components before replacing this timer.

Line Fuse If the washer won't start the line fuse might have blown.

Thermal Fuse If the washer won't start the thermal fuse may have blown. It can be tested for continuity. Watch our fuse testing video for more information.

Line Fuse and Holder If the washer won't start the line fuse might have blown, or the line fuse holder might be damaged and need to be replaced.

Main Control Board If the washer won't start the main control board might be defective. This is not common. Check other parts and causes first.

Door or Lid Latch Assembly If the washer won't start the lid switch assembly might be defective. This is a very common problem. The lid switch assembly can fail either mechanically or electrically. Test any electrical switches with an Ohm meter for continuity. The switches should have continuity according to their design.

Door Lock Motor and Switch Assembly If the washer won't start the door lock assembly should be checked. The door lock can fail either mechanically or electrically. Test any switches on the door lock with an Ohm meter. The switches should have continuity according to their design.

Incoming Power Problem If the washer won't start check to see if there is power at the electrical outlet which the washer is plugged into. Plug a lamp or radio into the outlet to check it. If the outlet is dead, check the circuit breakers or fuses for the home.

Power Cord If the washer won't start, check to be sure there is power to the electrical outlet for the home. If that is OK, the power cord itself might be defective. This is rare. You can check the power cord with an Ohm meter for continuity.

is there i ground fault switch at the power cord plug . if there is reset it . another problem with electric pressure washers is if water can't pass through wnd and nozzle they won't operate. there ian't a fuse inside unit.

But water comes out the end right? just under hose pressure only I bet. I have one of these units and every time I think it has gone bad I manage to find the problem. This unit not only has the switch on the front that needs to be on but it also has a safety switch on the plug where it plugs into a wall or extension cord. The last time I thought mine had gone bad it had actually blown the fuse. the unit was plugged into an outside outlet via extension cord. It just so happens that that is an GFCI outlet. I think the wife got water on the extension cord and that caused it to blow. So check:
The power switch on the front The safety switch on the cord, The outlet it is plugged into
Usually, for us, it is the button on the cord when it is plugged into an extension cord it always gets the test button bumped which shuts it down.

I ahve had Washer for 9 years. I has worked nicely. Now, it will not pump with house valve on. It will spray under pressure when the valve is turned off. I have rewired the plug in cord.

They are sensitive to large extention cords. My father in laws pops reset when a small cord is used. If internally shorted- motor will continually pop the reset even plugged direct to outlet. Check voltage at outlet.
