How to Fix E20 Error (Step-by-Step)

Disconnect the washer from both the power outlet and the water supply.
Locate the heating element, which is typically found at the bottom of the washtub.
Carefully disconnect the wires attached to the heating element terminals.
Remove the nuts or screws that are securing the heating element in place.
Gently pull the old heating element out of its housing. You may need to wiggle it slightly to release it from the seal.
