If your GE dishwasher isn’t draining properly, the drain pump may need replacement. This pump removes water during the drain cycle. When it malfunctions, water may pool at the bottom of the tub, preventing proper drainage.
Why Replace the Drain Pump Assembly?
The drain pump assembly is located beneath the dishwasher tub, connecting to the sump at the base. During operation, the pump moves water from the sump to the drain hose. If water remains in the tub after checking for blockages, it’s likely the pump is faulty and needs replacing.
