How Do You Troubleshoot a Whirlpool Dishwasher?

Troubleshooting a Whirlpool dishwater begins with unplugging it from the power source. The second step is to remove the lower spray arm of the dishwasher. To remove the lower spray arm, one must remove the four torque screws and the filter, and then check if the motor gear and chopper gears are working properly. It is also necessary to check if the water fill valve is open and functioning properly.

After removing the lower spray arm, take out the inlet protector by removing the torque screws and break the chopper to access the motor. The inlet protector covers the chopper assembly. To access the D-shaped opening, hold the chopper blade out of the way and ensure the chopper and motor gears are working correctly.

The sump area and spray arms must be cleared of any food or debris, and then one should locate the ribbon cable in the Whirlpool dishwasher’s door lining. If the drawer fails to dispense the detergent, one must check to ensure the cables are not broken. The last step is ensuring the water fill valve is open and functioning properly. If there is insufficient water and the valve is open, it is recommended to replace the valve.
