Drain Pump
The drain pump utilizes a synchronous motor with a permanent magnet rotor that is susceptible to impedance changes if water bypasses the internal shaft seal. When the seal fails, the rotor chamber fills with water, creating excessive drag that prevents the motor from reaching the necessary RPM to evacuate the sump. Replacing the pump restores the centrifugal force required to push effluent through the drain hose.

Drain Hose Check Valve
This rubber flapper valve is located at the exit port of the pump and is designed to allow one-way fluid flow. Over time, organic debris or calcium deposits can cause the valve to swell or stick in the closed position, creating a physical blockage. This prevents the pump from overcoming the head pressure of the water in the drain line, resulting in a failure to drain.

Main Control Board
The dishwasher's logic sequence triggers a mechanical relay on the control board to send 120V AC to the drain pump at specific intervals. If the relay contacts suffer from carbon tracking or pitting due to repeated arcing, the electrical circuit will not close, and the pump will never receive the signal to activate. Replacing the board ensures the timing and power delivery for the drainage phase are restored.
