Whirlpool fault codes and their meanings are found on multiple sites, including Part Select, AppliancePartsPros.com and Appliance Help Online. All three sites provide the fault codes for a variety of appliance types, as well as possible solutions for each fault code.
Each site has fault codes for Whirlpool ovens, ranges and stoves, duet front loading washers and dryers, and automatic Calypso washers. Some of the common fault codes for the ovens, ranges and stoves are communication, model ID and check sum errors, calibration shifted, latch signal mismatch, and stack overflow. The solution for these common errors is to disconnect the power for at least 30 seconds and wait at least one minute after reconnecting to see if the error code returns. If the error code does return, a part usually has to be replaced depending on the code.
A common fault code for the duet front loading washer is no water entering the machine or no pressure switch trip detected. For this problem, first make sure the valves are turned on all the way and there are no leaks or kinks in the hoses. If neither is the case, the Central Control Unit may have malfunctioned and may need to be replaced. For the duet gas and electric dryers, fault codes are often associated with the thermistor, which usually needs to be replaced for the dryer to work properly.
