Dishwasher is tripping off our safety switch

My dishwasher is tripping the power switch and the technician only tested the power cord and said that it is fine . it has previously leaked some water during the cycle. Don't you test the power to all parts of the machine , such as the pump , programme controls etc.

    another fisher and paykel tech is coming out today. let you know the outcome.

  • bonni Oct 10, 2007

    a very capable fisher /paykel tech came out today and did the same test on the power cord and found an earth problem. He was disgusted that the first tech said there was no prob with the machine.
    The first tech only used a low amp testing unit which the new tech showed would not register a problem. but by using a higher amp unit it immediately registered a prob with the earth and therefore he checked the machine finding the problem is with the motor.He also said that sometimes dishwasher tablets are two concentrated for machines and foam up to much .which can overtime cause a buildup of powder residue in the base of the machine. He suggested to use powder only.

    I have a simular problem. My dishwasher powers on and the cycle type set but when I close the door the circuit trips. I have tried an extension lead to a different socket but still the same problem. Any ideas?

It depends on what kind of test he was doing. He was probably checking the amp draw which checks how much power the whole machine was pulling. This would be the way to check the problem you have as long as he checked it with everything running, motor, heater,..etc. If you find the amp draw to be too high, then you go to individual components.

    I hate to second guess another technician on a unit he has checked and I have not. I would plug it in to a heavy duty extension cord and tried it on another circuit. If it doesn't trip the switch then, I would plug something else to the circuit the dishwasher was on to see if that tripped the circuit. If it doesn't, then I would start wiggling wires on the dishwasher to see if I can find a short somewhere. If it trips as soon as you plug it in, without turning it on, it shouldn't be hard to find.

We sold our bosch dishwasher, working perfectly. New owners transported it on its back. Now it won't start, or even show that it is getting power, though the outlet works. What has happened?

Hello KT;

My name is Peter. I am a retired field service appliance technician.

Transporting the dishwasher on its back should not have been a problem. It is only with refrigerators and freezers that need to be transported up right, to prevent compressor oil getting into the refrigerant sealed system.

You may have a power cord problem. You have a 3 or 4 wire power cord. If you have a 3 wire power cord you need a 15 amp circuit breaker. If you have a 4 wired power cord you need a 30 amp circuit breaker.

The wall socket that you are plugged into my not have a ground.

You need to check the wall socket and the wire connects at the dishwasher. Send me a model number so I can see what you have. If you have a 4 wire connection you can chance the cord to a 3 wire. On a three wire you have a neutral and two hot with a small green ground wire. On a 4 wire you have a neutral two hot wires and a neutral in the center with a ground wire.

I would put my money on the wall socket not having a ground.

Send me a model number and I will help you.

Samsung dishwasher wont run; delicate cycle light blinking

see this causes and fix it. God bless you
1. No power to the dishwasher
Make sure there's power getting to the dishwasher. Check for a tripped circuit breaker or a blown fuse. Check the wall socket for power. Sometimes the power cord disconnects at the dishwasher (inside the junction box, behind the bottom kick panel), if this is the case, the wiring must be repaired or replaced.

2. Door switch
Replace if defective.

3. Timer
Replace if defective (note: uncommon problem).

4. Selector switch
Replace if defective (note: uncommon problem
5( test the main board can be faulty and replace.

My candy CDI45 is not working, it just keeps beeping and saying E2. Any tips on getting it working again would make me a happy lady again.


E2 is called water safety level error. Unfortunately the problem is often caused by either a defective pressure switch or by a defective control board. The problem is quite common in SMEG built dishwashers like your Candy.

All you can do is disconnecting power for a couple of minutes, by either tripping circuit breaker or disconnecting power cord. That will reset control module. While power is off remove water (if any) from the bottom of the appliance.

If that does not do the job the parts must be tested and the appliance must be repaired replacing defective part.

When switched on the machine trips the power. Changed fuse in plug and tried different socket but still same problem? took bot of machine no visable burn or soot marks? any ideas

Is it tripping the breaker in the breaker box? If so you have a short to ground. Could be A bad spot on the dishwasher cord. Turn power off and pull dishwasher out and check the power cord all the way back to the dishwasher terminals

My dishwasher keeps telling me F51 cannot find in the book what that means can you tell me please have cleaned all filters

On Miele F51 is pressure switch error.

The pressure switch is located in the drain system. Its function is determining if there is water inside the tub.

Trip the circuit breaker or disconnect the power cord for a couple of minutes. Inspect the drain system for blockage. The pressure switch can be tested by a technician bypassing it.

To get parts or repair service, call the number listed on the user manual.
