The dishwasher will not turn on

If your dishwasher will not switch on and you have already switched it off and back on at the power point, there are a few potential causes for the issue:

1. Tripped Circuit Breaker: Check your home's circuit breaker and see if the breaker for the dishwasher has tripped. If it has, switch it back on.
2. Door Latch: Make sure that the dishwasher door is closed and latched properly, sometimes the dishwasher will not turn on if the door is not closed or latched correctly.
3. Control Board: The control board is responsible for controlling the various functions of the dishwasher. If it is malfunctioning, it may prevent the dishwasher from turning on.
4. Power failure: If there was a power failure in your area, the dishwasher may have shut down and will not turn on until power is restored.
5. Water supply: Make sure that the water supply to the dishwasher is turned on and that the water pressure is adequate.
6. Drain hose: Make sure that the drain hose is not clogged or blocked.
7. Water inlet valve: The water inlet valve controls the flow of water into the dishwasher. Make sure it is not clogged or blocked and that it is functioning properly.

It's important to check all these possibilities before calling for a repair technician, as some of these issues can be resolved easily. If none of the

Check your circuit for a fault.
Domestic appliances have a capacitive RF filter in the mains input. Switch both live and neutral off with a double pole switch at the consumer unit when you are away. That will stop the residual current trip breaking when the neutral line is still connected.

It may have tripped the internal breaker, and or the house circuit breaker. Go tot the house fuse box and check that first.

the surge could have fried the circuit board in the dishwasher or maybe the house circuit it's hooked into. maybe first check all of your breakers in your breaker box just to be sure one of them isn't tripped

Check the breaker in your breaker box, it may have tripped. Reset it and run the dishwasher. If it trips again, have the dishwasher looked at by a professional service person.

Is this happening only now! If it was working OK earlier and tripping now only it may be due to some electrical fault inside the machine.

Switch off all the high power appliances and try the dish washer. If it works you have to check the breaker overall power rating!

If it trips during dish washer ON, the fault could be in the heater circuit of your machine. Heater Insulation would have become weak etc.

You might need to contact a different electrician. Also a different retailer of machines as this one is obviously trying to make a sale. The apparent problem is that the house is wired with all of the outlets in the house on one circuit breaker--a recipe for trouble. Any house with multiple outlets should be divided into zones so that the whole house doesn't shut down if one appliance trips the breaker. A heavy user of power like a dishwasher should have it's own breaker and wiring for that machine alone. The electrician should have load-checked the dishwasher to make sure it is not drawing more than rated power, then suggested that it be wired to it's own breaker and circuit. Any other high power appliances should also have separate circuits (washing machine, microwave, toaster, etc.). Hope this helps!

Try to turn off everything else that is on the same circuit then turn on the dishwasher. If the breaker still trips then the circuit breaker might be malfunctioning or the dishwasher might be defective (in which case the circuit breaker is doing exactly what it is designed to do.) I would bet that it's the dishwasher thats causing the problem. Check with the manufacturer to see if there are any recalls on that model.

If your dishwasher doesn't work at all, check these:

Power from the house
Door switch
Wiring
Timer or selector switch
Power from the house Is there power getting to the dishwasher? This can be difficult to test, because dishwashers are usually wired directly to an electrical circuit, rather than plugged into the wall. But at least check for a blown fuse or a tripped circuit breaker.

Door switch The door switch is important because, if it's defective, the dishwasher won't work at all. To reach it, you need to remove the control panel cover, or sometimes the interior liner of the door. If it's defective, you need to completely replace it.

Wiring Often the main wiring connection from the house, at the dishwasher, burns and breaks the connection. If that's the problem, the wires must be repaired/replaced as necessary. If that's not the problem, check the wiring to the door switch, the wiring between the door and the lower part of the dishwasher, and the wiring to the timer. Repair any broken, burned, brittle, or defective wiring, using the proper appliance-grade wire and connectors.

Timer or selector switch Although it's uncommon, the timer or the selector switch may be defective. If so, you need to replace the defective part, because neither of these can be repaired.
