Maytag Washer Error Code F51

F51 on a Maytag washer indicates a Motor Rotor Position Sensor (RPS) failure or a problem with the lower wiring harness connected to that sensor. The RPS monitors the motor rotor's position and speed, and the control board uses that data to run the motor correctly. When the signal is missing or invalid, the washer stops and displays F51. Diagnosis should follow the TEST #3 procedure to isolate whether the fault is in the sensor, the harness, or its connectors.

It is not advisable to continue using the washer while F51 is active. The washer has stopped operation specifically because motor control has been compromised, and running it in this state could cause further damage to the motor or associated components. Resolve the underlying fault before resuming use.

A power reset may temporarily clear the F51 code, but it will almost certainly return if the underlying problem with the rotor position sensor or lower harness has not been corrected. Resetting without performing a proper diagnosis only delays the repair and risks further component damage. The fault should be properly diagnosed and resolved using the TEST #3 procedure before relying on the machine again.

A knowledgeable DIYer can address some F51 causes, particularly loose or corroded harness connectors, without professional help. Inspecting and reseating connectors along the lower harness requires basic mechanical aptitude and no special tools. However, if the rotor position sensor or motor control board needs replacement, comfort with appliance disassembly and electrical testing is necessary. When in doubt, a qualified technician should perform TEST #3 to correctly identify the faulty component.

Repair costs vary depending on the root cause. If the issue is simply a loose or corroded connector, the repair may cost little to nothing beyond diagnostic time. Replacing the rotor position sensor typically runs in the range of $30 to $80 for the part alone, while a motor control board replacement can range from $100 to $250 or more for parts. Adding professional labor will increase total costs depending on your area and service provider.
