Drain Pump Motor
The drain pump uses a synchronous motor that can suffer from winding failure or a cracked impeller hub. If the motor cannot generate sufficient torque to overcome the head pressure of the drain line, it will fail to evacuate the tub, leaving standing water at the end of the cycle. This is the most common mechanical cause for non-drainage in this model series.

Drain Hose with Check Valve
This component features an integrated rubber check valve flapper designed to prevent wastewater from siphoning back into the dishwasher from the sink or garbage disposal. If the flapper becomes distorted or obstructed by food debris, gravity will pull water back into the bottom of the tub after the pump shuts off, resulting in dirty standing water.

Water Inlet Valve
The inlet valve utilizes a solenoid-controlled diaphragm to manage water entry. If mineral deposits or internal spring fatigue prevent the diaphragm from sealing completely, water will slowly weep into the unit even when it is not running. This results in the tub gradually filling with clean water over several hours or days of non-use.
