What Does Monogram Washer Error Code E52 Mean?
Error code E52 on a Monogram washer indicates a motor speed sensor (tachometer) fault. The control board is not receiving proper speed feedback from the drive motor, which prevents it from controlling spin and agitation speeds correctly.
Common Causes
- Failed tachometer / Hall sensor – The speed feedback sensor on the motor has failed.
- Loose motor wiring – The wiring harness connector at the motor or control board has partially disconnected.
- Worn motor brushes – On brush-type motors, worn brushes create erratic speed signals.
- Control board fault – The inverter or motor control module has failed.
How to Troubleshoot
- Hard reset – Unplug for 5 minutes and retry. Intermittent E52 can result from a temporary sensor glitch.
- Reduce load – An extremely unbalanced or oversized load can overload the motor and trigger speed faults.
