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.

Karcher electric pressure washer help starting


The test / reset buttons are for a Ground Fault Interrupter built into the cord / washer. This device will help prevent deadly electric shock in the event of a malfunction - it is the same technology used in "GFI" electrical outlets located in bathrooms, outdoors, basements, etc.

You should have this serviced - or replaced before using.

Good luck!

Is there a fuse on model no jvm1540dn1ww


There should not be a fuse on your washer- what is usually the problem here you have a reset button the power cord- also be sure to check if you are plugged to a GFI circuit-
if this is the case unplug the power cord-
reset the GFI outlet (wall plug)-
plug your power cord back into wall-
and push in the reset button-

Dosent run after plugged in to power. motor seems to be frozen


Two potential problems, notwithstanding complete failure, faulty cord, faulty plug, faulty electrical outlet. All of the above need elimination before attempting the following:
1.) A faulty on/off switch. You will need a multimeter to test for continuity. Not a task for those not competent.
2.) Faulty control head which is not telling the motor to turn on. A valve is stuck in the head and the machine does not know that you want to use it.It thinks that you have triggered off and has stopped. Probably a job for a specialist. Definitely not a job to tackle without a spare parts breakdown.

Please, everyone.....
DO NOT MUCK AROUND WITH ELECTRICITY IF YOU ARE NOT COMPETENT.
MAKE SURE THAT YOU HAVE AN EARTH LEAKAGE DETECTOR BETWEEN YOU AND THE POWER SUPPLY

Electric pressure washer will not start


CLEAN FRESH WATER IS IMPORTANT FOR THESE PUMPS, I ALWAYS USE A HIT OF ARMOR ALL IN THE PUMP AFTER USE . YOU MIGHT SEE IF IT'S GETTING POWER TO THE MOTOR MIGHT HAVE A BAD GFIC ? PLUG IT IN PICK UP THE UNIT AND TRY DROPPING IT FROM A FOOT OFF THE GROUND, THIS JAR MIGHT SHOCK IT BACK TO LIFE ?

It won't start. when I push the test reset button it attempts to come on for a second then nothing. I changed outlets and same thing happens. before I did this the water would come out of the nozzle...


Had a similar problem with a Karcher that I own, after a little troubleshooting it turned out to be the big plug end with the reset in it, I took the plug end apart and found the contacts inside had melted thus not allowing proper contact of the reset button, I opted for a cheap way out, instead of ordering a replacement reset plug assy i changed it over to a regular 3 prong gfi plug end, been working great the past few seasons,hope this helps

When i operate the switch on my karcher pressure washer the power wash does not operate.


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.

My karcher electric power washer will not start-1800 psi


If you have used an extension cord with it you have destroyed the motor. If not, the bypass valve is stuck. On THIS diagram, section 2.1, part number 1 needs lubrication with a good waterproof grease.
