Whirlpool Washer - F06 Error Code

Motor tachometer error.

Meaning

Motor tachometer error.

The F06 error indicates that the washer’s motor tachometer is not providing valid feedback. Whirlpool Duet washers use a tachometer sensor built into the motor to monitor drum speed. If the control board does not receive expected RPM signals, or if the tachometer output is erratic, the washer triggers F06 to prevent unsafe motor operation. This error is common when the motor, tachometer, or wiring harness is failing, or when the drum is obstructed.

Symptoms

  • Washer will not spin
  • Drum moves weakly or jerks
  • Cycle stops during wash or spin
  • F06 appears shortly after starting

Causes

  • Faulty motor tachometer
  • Loose or damaged wiring harness
  • Failed motor control unit (MCU)
  • Drum obstruction or seized bearings
🔧

Step-by-Step Fixes

  • Inspect the motor wiring harness for loose connections.
  • Check for drum obstructions or seized bearings.
  • Test the motor tachometer with a multimeter.
  • Replace the motor or MCU if readings are out of range.
⚠️

Safety Notes

  • Disconnect power before accessing the motor or MCU.
