I own a stanley pressure washer and it keeps tripping out

The valve-o-rings + [ parbaks seals ] where the pressure can be adjusted with.
Control the water inlet filter or hose that there are no waterlock couplers are used or is mounted
on the wrong site on the hose , that it is used as water inlet on the tap.

Jeff, the specs say it is 230 volt, 16 amp minimum, start up would be more, probably minimum 20 amp.or larger, check your manual. Are you using a small gage/ low capacity extension cord this could blow a breaker or may have an internal short have checked by a Karcher repair center. Check the attached links,instruction and guides, Good luck

SAE 30W non detergent is advised by Stanley Dewalt

Disconnect the wand from the washer if you get water coming out of the discharge, the problem is in your wand or the line is plugged going to the wand.

There is a spring in there that makes it recoil. It has probably broken. Depending on who made the engine you can get a replacement for the whole assembly. A small engine shop should be able to replace it for a not a lot of money.

First be very careful because the unit is protected by a ground fault internal circuit interrupter and may trip if there is a short circuit to ground. Even a very small short circuit will trip the circuit breaker.

Something else: If you are plugging it into an already existing ground fault outlet then that may also cause one of the breakers to trip.

Like I first mentioned, if you don't know what your doing be very careful. Electricity and water are not friends, especially if the circuit breaker is tripping.

Good luck,

Need more info:
What fuse? the one at the end of the cord on the pressure washer? Or the circuit breaker on your house?

If it is the one on the cord it may have gone bad. To test replace it with normal plug (non-GFI) and plug it into an outdoor or bathroom GFCI (GFI) outlet. If it still trips that outlet then there is a ground fault in the device which may be minor or major.

If it is a home circuit breaker remember that electric pressure washers use a lot of power - typically 1500 watts. If anything else is plugged in it can trip the house circuit breaker.

Check for any missing washers or seals or check to see if they're not broken.

The female hos bib connection should have a typical hose washer inside.Often you can't tighten the nut tight enough without this washer, to keep it from leaking both from the hose, and the rest fo the fitting into the washer.

it has a reset button somewhere and usually a fuse. take the cover off (unplugged) and look for a red reset button or a fuse. if it keeps blowing the fuse or tripping the reset then it will likely need service by a service center.
