GE Dishwasher C1: Drain Pump Motor Not Responding
C1 on GE dishwashers signals the drain pump motor drew zero current when the control board commanded it to run. Post-2016 GE dishwashers (manufactured under Haier ownership) use a permanent-magnet drain pump with a twist-lock mount on the sump housing.
SmartHQ Remote Diagnosis for C1
WiFi-equipped GE dishwashers (Profile, Cafe lines) allow SmartHQ app diagnostics that report whether the board relay activated, whether the pump drew any current, and the drain cycle duration before timeout. This data distinguishes relay failure from pump failure without opening the machine.

Manual Diagnosis Without SmartHQ
For non-connected models, enter test mode by holding Heated Dry + Start for 3 seconds. Navigate to the drain test — the pump should activate audibly. Silence during the drain test confirms no power reaching the pump or a dead motor.
Pump Motor Testing
- Kill power at breaker
- Remove kick plate (Phillips screws or push-tab clips)
- The drain pump sits at the sump base with a twist-lock mount
- Disconnect the 2-pin motor connector
- Measure winding resistance: 12-20 ohms expected. OL = open winding, replace pump
Impeller Inspection
Access the impeller through the drain outlet fitting. Spin by hand — should rotate freely with slight magnetic cogging. Seized impeller from glass fragments, seeds, or mineral buildup is the second most common C1 cause after motor burnout.
GE vs Haier Design Evolution
Pre-2016 GE dishwashers used a belt-driven drain mechanism. Post-Haier models switched to direct-drive pumps that are quieter and more efficient but have different failure modes. Pre-2016 C1 may indicate belt failure rather than pump motor failure.
Safety First — Know the Risks
Live 120V wiring in a wet environment is one of the most dangerous DIY scenarios. Water + electricity = serious shock risk. Our techs are licensed and insured — let them handle the risk.

- Disconnect electrical connector
- Twist pump counterclockwise 90 degrees, pull down
- Install new pump (WD26X23258): twist clockwise to lock
- Reconnect hose and electrical, run rinse cycle to verify
