How to Replace Standard Electrical Outlet For Dummies How To Replace An Old Electrical Outlet Wall Plug Replacement

Can often be just the element in the oven that has gone faulty. Try disconnecting the element (usually can be done from inside the front of the oven), isolate the spade connectors and then turn on. If it doesnt trip then you know it is the element. £10 or so on ebay gets you a new one

You say you checked "socket" and the "fuse," did you mean the AC wall outlet (115V) and a fuse or breaker in the main power panel?
Nearly all circuits involving water are protected by a Ground Fault Interrupter that can be servicing several wall outlets (perhaps one not near the washing machine) or can be located as part of a circuit breaker in your main power panel.
The GFI outlets will have one or two push buttons located between the outlets and a combination GFI/overcurrent breaker will also have at least one button where others will have none.
If you find one that is tripped, try resetting it. If it will not reset, unplug the washing machine and try again.
If it now stays on, your machine may have an electrical path causing it to trip and using an unprotected outlet may be unsafe and an indication that the appliance itself may have electrical leakage which could be otherwise dangerous.
The circuit breakers in the main power panel can also fail (they didn't 20 years ago) and we have replaced 3 in a home only 5 years old already so they are not made well anymore.

Get a new electrician! The pool pump should be on its own isolated circuit, usually on no larger than a 30 amp GFCI protected breaker. You said it was replaced but he only treated the symptom, not the cause. This one will take on site troubleshooting to find out why your whole house is affected.

go to the qualified electricians on your place... but there is some helpful tips that can help you.. (1) for continued protection before starting. turn off the main circuit breaker. (2) unplug all the appliances or equipment installed... (3) check all the wall socket outlet... look for any damages on the wall socket... if the wall socket outlet have no signs of burned or wet marked, try to turn on the circuit breaker. check if the problem is solved.. (4) if the wall socket outlet have a signs of burned or wet marked.. just replace that w/ the same type of socket... check also the appliances that may caused the problem... the easiest way to know is to look at the socket plug itself... ty

You already unpluged before the wall work, so the problem is isolated from the dryer from its plug. Take off the wall socket to inspect since it may have damaged. If you have the voltmeter, measure each pair of the terminal. they should have a voltage at least 110V since it is three-phase voltage. If there is no voltage then just replace the socket. Make sure to turn main power off when you do the replacement.

Not if you can access you main electrical panel. You should be able to turn off the 50 Amp Double Pole Breaker that provides power to the wall oven/ Note, sometimes it's a 40 or a 60 amp breaker depending on the age and requirements for the wall oven.

You should be able to turn off the breaker and safely remove the oven and disconnect the wiring connections once you pull the oven out of the opening. Be sure to fully tape each wire once you disconnect them from the oven to prevent an accidents - also, LEAVE THE BREAKER OFF until the new oven has been properly installed!

IF you aren't sure which breaker it is and really want to be ultra safe, you can shut off the main breaker, but you'll be without power until you've got the oven removed and have safely taped each conductor with SEVERAL wraps of electrical tape to prevent contact with the bare conductors.

Hope you found this very helpful and best regards!

Is this wired directly to the Breaker/fuse box?
Or is there an electrical outlet socket under the sink that this plugs into?
Possibly for the former you may need to turn off the breaker, remove the fuse to turn off the power. Unscrew the machine where it is attached to the counter and pull it out from the counter. Where the wire is attached to the machine, unscrew it and remove it from the machine. The machine's drain hose should be removed from the drain where it is attached to the disposal or the drain pipe. Then you can discard the old machine.
If there is an electric socket that the power is plugged into unplug and follow the rest of the procedure. Otherwise after removing the machine, get an electrician to install a plug outlet so that your new machine can be plugged into the wall socket and alleviate this problem in the future.

I dont mean this to sound arrogant. but if you have to ask you might be best to have a professional to do it. the wires coming into the box will be hot without being able to pull meter off of house to disconnect. the panel has to come off and many are different
