Maytag Washer F51: Motor Rotor Position Sensor Fault

Quick Answer

Maytag F51 means the control board lost track of the motor rotor position. The hall sensor (a small circuit board on the stator) is the first thing to check - it is a common fail point and costs about $15. Remove the back panel, take off the rotor bolt, pull the rotor, and inspect the sensor and its wiring harness.

F51 has three causes ranging from a $0 fix to a $300 repair. First check: unplug the RPS connector at the motor base, clean the terminals with electrical contact cleaner, reconnect firmly. In 30-40% of F51 cases, this connector fix is permanent. Second: replace the RPS sensor (W10183157, $15-30). Third: failed stator winding (expensive). Test RPS: should read 1000-1200 ohms. Test stator: should read 4-6 ohms between any two of the three wire pairs.

What Does the F51 Code Mean?

F51 is generated when the control board receives no position feedback from the rotor position sensor during motor operation. The RPS is a hall-effect sensor mounted adjacent to the motor rotor that reports shaft position 120 times per revolution, allowing the board to control motor speed and direction precisely.

Most Likely Causes

Based on aggregated repair data, here is the probability breakdown for this error code:

Hall sensor failed or dirty50%

Chipped rotor magnet25%

Stator winding fault15%

Wiring harness issue10%

Symptoms You May Notice

F51 code displayed - motor rotor position sensor fault
Drum does not spin or spins then stops with error
Loud grinding noise before the code appears
Washer agitates but fails during spin

Can you reset a Maytag washer to clear the F51 code?

After RPS repair: unplug washer for 60 seconds. Run a Spin Only cycle to confirm F51 is cleared before running a full load.

Diagnostic Checklist

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

Clean RPS connector at motor base

Disconnect power. Tilt the washer back to access the motor from below. Locate the RPS connector at the base of the motor. Disconnect it, spray electrical contact cleaner on the pins, reconnect firmly. Restore power and run a spin cycle.

Test RPS resistance

Inspect rotor magnets

Test stator resistance

Inspect motor-to-MCU wiring harness

ComponentComponent Under Test

Expected Range1000–1200 ohms

ConditionIf Open (OL) or infinite, replace component.

Replacement Parts

If your diagnostic testing proves the component has failed, you will need a replacement. We recommend OEM parts over aftermarket for water-handling components.

Frequently Asked Questions

What is a rotor position sensor on a Maytag washer?

The rotor position sensor (RPS) is a small sensor mounted at the base of the direct-drive motor. It reads the position of the spinning rotor magnets and reports motor speed and position back to the control board. Without this feedback, the board cannot control spin speed or agitation direction. It is similar to a crankshaft position sensor in a car engine.

Can I fix F51 myself or do I need a technician?

The connector-clean fix (Step 1) is beginner-level. The RPS sensor replacement (Step 2) is intermediate - it requires tipping the washer and accessing the underside. The stator replacement is advanced and may cost more in parts and labor than the washer is worth. Try the connector clean and RPS replacement before calling a technician.

How much does the rotor position sensor cost?

The RPS sensor (W10183157) costs $15-35 depending on the supplier. It is one of the most affordable electrical components on a direct-drive washer. If cleaning the connector does not resolve F51, replacing the RPS sensor is the logical next step before considering more expensive repairs.

Why does F51 only happen during spin?

The RPS only matters during motor operation. The fault appears during spin because that is when the control board is actively reading motor position feedback at high speed. At low spin speeds during agitation, the fault may not trigger - but at high RPM, any break in the RPS signal is immediately caught by the board.
