Whirlpool Dishwasher runs for several hours

Common solutions for: Whirlpool Dishwasher runs for several hours

01 - Heating Element
The heating element can be used to raise the temperature of the water in the dishwasher during the wash/rinse cycle. In certain cycles if the heating element does not sufficiently heat the water the cycle will not advance causing the dishwasher to run for several hours. To determine if the heating element assembly has burned out, use a multimeter to test it for continuity. If the heating element assembly does not have continuity, replace it.

02 - Water Inlet Valve
The water inlet valve opens to allow water to enter the dishwasher. If the valve is clogged or defective, the dishwasher won’t get enough water to clean dishes properly. Lack of water to be heated could also cause the dishwasher to run for several hours. If the water inlet valve is clogged, replace it. Do not attempt to clean the water inlet valve—cleaning the valve could make it more likely to fail.

However, this is not likely the case. Control boards are often misdiagnosed—make sure you check more commonly defective parts before replacing the main control board.
