GE PROFILE PDT715 Not Draining

Drain Pump Assembly

The drain pump is a synchronous motor that uses a permanent magnet rotor to drive an impeller. If the internal seals fail, water enters the motor windings causing an electrical short, or debris physically jams the impeller, preventing the centrifugal force required to push water through the check valve and out the drain hose.

Pressure Sensor Assembly

This model relies on a pressure sensor to detect the hydrostatic head (water level) in the sump. If the sensor's diaphragm is fouled by fats/oils or the sensor fails electronically, the control board fails to trigger the drain sequence because it cannot verify the presence or absence of water, often resulting in a mid-cycle halt with standing water.

Fine Filter and Sump Screen

The fine filter captures particulate matter to protect the internal spray jets and drain pump. Over time, a buildup of calcium or organic biofilm can create a hydraulic seal that prevents water from entering the sump's drain intake, effectively starving the pump and preventing evacuation despite the pump motor functioning correctly.
