We have been having problems with item melting when we run the dishwasher, and now noticed the the lower spray arm has started to melt as well. Could this be a thermostat problem or something else.
You would want to test the thermostat to make sure that it is good but it could also be an issue with the relay in the control board sticking. You will want to check to make sure that there is not constant power going to the heating element without shutting off.
Unit makes a sizzling sound and does not drain.
Answer Hello Dennis. See if the noise is coming from the control board. If so, you will need to order and replace the board in the unit.
