My dishwasher had been taking a long time to complete a cycle. One time it took 6 hours. It got so hot yesterday my plastic coffee cup is now oval shaped. Today I ran it with no dishes in it and the water doesn't seem to get hot enough while washing but at the end of the cycle it gets hot even though drying cycle is off. When I opened the door steam came out. Any ideas on what parts I need to replace is appreciated.
Thank you.
