Hi

E04 as you may have worked out is a heating related error code in there. This is usually down to either the heater itself is either open circuit or its shorting out to earth or its a faulty control board.

If you are looking at fixing this yourself then you need to acces the heater unit under the dishwasher and test it and see if it either faulty or its down to earth. Now you will need a megger or instualtion meter to test it to earth.

But if the heater tests all ok then its going to be the control board at fault as they heater relay on there could have failed which is causing this fault here.

So thats what the E04 error code means so check that if you can and see what you find from there.
