How to Fix / Troubleshooting

Safety: Disconnect power and turn off water before accessing the base.

Verify fill: Open the door mid-cycle to confirm there is adequate water in the tub.
Listen for motor: A loud hum with no water movement suggests a seized pump.
Inspect pump: Remove toe kick, locate circulation pump, and check for leaks or burn marks.
Check for obstructions: If accessible, remove the pump and inspect the impeller for foreign objects.

If the motor is seized or windings are open, replace the circulation pump assembly with a Monogram-compatible part.
