Dishwasher trips out after running for a while

It sounds like the combined use of both washer and dishwasher plus any other appliance on the ring main are overloading the circuit. Run the dishwasher a few times and see if it trips. Then do the same with the washer. Then run them both.

Your electrician should have been the one to diagnose the issue!

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.

not necessary-- yet-- to buy a new unit
tripping the rcd is an indication of earth leakage which could amount to water in the wall plug across pins, moisture across the power board, water in the motor, faulty heater element
what you need is an accredited electrician to run tests on the system to find the reason for the earth leakage that is tripping the rcd
the rcd works from microvolts and operates in nano seconds to prevent electrocution of the operator
testing before buying may save heaps of cash

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.

Most Whirlpool manufactured dishwashers have a thermal fuse, located inside the operator console. When tripped, the dishwasher will not run. A power outage can cause the thermal fuse to trip. It cannot be reset and has to be replaced, if bad. Please post back with your COMPLETE MODEL NUMBER (located around the door opening) so I can determine the configuration of your dishwasher and explain how to access any potential fuses. -->

Hi,

Here is a tip that I wrote that will help you ti find out why the circuitbreaker is tripping.

Circuit Breaker Keeps Tripping
heatman101

the problem will be in the circuit to the door
opening the door and it trips the breaker indicates that the hinge is rubbing on a wire or making the harness move to ground out

its quite common for the interferance filter to fail on these models its situated in the base of the dishwasher connected to the mains block usually when they fail you can see black dust around it,

chucked it !!

Hello,

My dishwasher a diplomat 12 program (hja8640) was doing exactly the same where every now and again when turned on at the plug it would trip. After engineers coming out several times and failing to fix it, they condemed it. New one was supplied, however did exactly the same thing. The electrician came back, checked the RCD power breaker and this was fine. It was then discovered that some dishwashers and washing machines send out a lot of earth leakage, combine this with other appliances on in the house can be enough to trip.

Soloution. The electrician removed the kitchen circut from the RCD breaker and intalled another breaker RCD just for the kitcehn loop, this therefore means that the kitchen has a seperate trip from the rest of the house, and touch wood, has solved the problem. This mind you has taken about three months to work out so i hope it saves you some time.

Always use a fully qualified electrician though.

Thanks.
