What is a General Electric Dishwasher Drain Pump?
The General Electric dishwasher drain pump is a motor-driven device responsible for removing wastewater from the dishwasher’s tub at the end of each cycle. Once the washing and rinsing phases are completed, the drain pump activates to siphon out dirty water, allowing fresh water to be supplied during the next wash cycle.
How Does the Drain Pump Work?
The drain pump works in conjunction with the dishwasher's control board and sensors to ensure water is expelled efficiently. When activated, the pump spins its impeller blades, creating a flow that pulls water from the sump area and pushes it through the drain hose and out of the dishwasher’s drainage system.
Key Components of the Drain Pump System
- Pump Motor: Powers the impeller to create water flow.
- Impeller: A rotating blade that pushes water out.
- Pump Housing: Encases the impeller and motor for protection.
- Check Valve: Prevents backflow of water into the dishwasher.

- A reading of zero or infinite resistance indicates a faulty motor.
Step 3: Listen for Unusual Noises
- Reconnect power and run a short cycle.
- Listen for humming or grinding sounds, which could suggest a failing impeller or motor.
Step 4: Check for Error Codes
- Consult your dishwasher's user manual for specific error codes related to drainage issues.
