One circuit fails to conduct electricity. The breaker has been replaced and a GFCI was installed in place of a regular outlet in the bath. This did not fix the problem.

How can I figure out where the problem is?

The house is wired with #14 wire. The circuit failed while using a 1600V power washer. It looks as though the entire circuit is bad but I don't know how to figure out where.

Thanks,

It's witchcraft, I tell you. They try to tell us that little electrons flow along the outside of the wire. I say "show me".

I'm sure an expert will be along with a more sympathetic answer.

How long did the power washer work before the electricity failed? Did the power washer work in other outlets? Is the reset button working on the GFCI, did you feel it click? Did you use a tester, outlet tester, circuit tester, other? Tighten the screw on the white wire? Please have someone that is knowledgable in electricity check it out. If you could answer some of these questions, It will help narrow down the source of the problem. Good luck.

What size was the original circuit breaker? How many "things" (lights, receptacles) are also now dead? Are all of the "things" on this circuit dead? Or just some? Does the GFI trip out or is it completely dead?

Maintenance6 is on the right track, but its easier to do than to explain how to do it.

The typical solution is to find exactly where the circuit is losing its power, staring at the output of the breaker. If you don't already know what devices are on this particular circuit, you'll have to either tone out the wire or open walls and trace it out. An electrical professional will have the correct tools, and at some point you have surrender and call for some help.

Try looking for another GFCI that tripped when the over current occurred. There are instances where multiple GFCI outlets are improperly wired on the load side. This can happen on basement, outside or even bathroom outlets that are not used often. Try to locate all GFCI outlets and test then reset them. If there is an upstream GFCI tripped you may have just found your problem. Good Luck.
