Our dishwasher trips the circuit/earth leakage switch

Customer Question

Our dishwasher trips the circuit/earth leakage switch occassionally when in one of the last phases. Seems to be very hot. Allowed to cool it then resets and no longer trips the earth leakage switch on the house circuit board

Can you post the make and model number of the dishwasher please.

Also if you run a cold rinse cycle only does this work ok still?

SMEG Dishwasher model SA 622X serial no:###-##-####It runs only on cold water. It was bought second hand and we have no manual with any detail or FAQ. Tried search the net for one but nothing comes up. The unit has very few controls. Just an on off button and a round knob that you use to dial the wash cycle. We use numbers 2 and 3. Seems less likely to trip on 3. No controls for water level or ways to make adjustments to cycles.

Thanks for that. Looking at this its quite a few years old is this dishwasher.

From the sounds of this I think you may find the heater element is the fault. As on a heater when it gets hotter it goes to earth and this is when it trips the electrics out. Once its cooled down and gone cold then it normal clears itself and works fine.

If you are looking at fixing this yourself then you need to pull the dishwasher out and lie it on its back.

Then remove the bottom base cover and from there locate the heater.

Disconnect the wires to the heater and tape them up.

Then set the dishwasher going on a cycle and see if it runs without tipping out then.

If it does then the heater element is the fault and will need to be replaced to cure this from there.

Check that if you can and see what you find.
