Whirlpool Washing Machine: drain pump running continuously
What is this symptom?
Is your Whirlpool washing machine's drain pump running continuously? This issue often occurs when the machine is idle, preventing normal cycles from starting or progressing. Common causes include a faulty pressure switch, control board issues, improper drain hose installation, or, rarely, a mechanical fault in the drain pump itself.
Important Tips for Whirlpool Models
- Some Whirlpool models may require recalibration resets to clear continuous drain behavior.
Possible Causes
Faulty pressure (water level) switch or blocked pressure hose
How to Identify: Pump runs continuously even with no water present; washing machine believes water remains due to false signal; inspect pressure hose for kinks/clogs.
Part: Pressure switch / pressure hose
Control board or electronic control fault
How to Identify: Pump runs without logical trigger; resets or recalibration procedures sometimes resolves symptom; widespread cycles fail to progress normally.
Part: Electronic control board
Actual water level or siphoning (drain hose installation issue)
How to Identify: Pump appears to run to remove water when drain hose inserted too deeply or improperly, causing siphoning/backflow.
Part: Drain hose
Drain pump mechanical fault
How to Identify: Pump runs constantly and fails to evacuate water properly; unusual noises from pump.
Part: Drain pump assembly
DIY Solutions
Inspect and clear pressure hose blockages
- Unplug the washer and move it to access the back or side panel.
- Locate the pressure hose that runs from the tub to the pressure switch.
- Disconnect and inspect the hose for clogs or kinks; clear any debris gently.
- Reconnect the hose securely and run a test cycle.
Reposition or adjust drain hose to prevent siphoning
- Ensure the drain hose is not inserted more than recommended into the standpipe/drain.
- Adjust the hose height per manual recommendations (typically hanging at proper standpipe height).
- Test to see if the continuous pump running stops.
Reset / recalibrate the washer control
- Unplug the washing machine for 1-2 minutes.
- Plug the washer back in to reset controls.
- Attempt to start a cycle to see if control resets have resolved the symptom.
