Frigidaire Washing Machine E52 error code

The control is getting a bad signal (or no signal) from the drive motor's tachometer, the sensor that reports motor speed.

Also shown as: E52

Last updated: October 6, 2026

Quick answer: Frigidaire washing machine error code E52: bad motor speed signal. The most common cause is loose motor wiring connector. Try this first — balance the load. If that does not clear it, power-reset the washer. If the code persists, call a qualified technician.

What causes the E52 error?

  • Loose motor wiring connector
  • Failed tachometer (speed sensor) on the motor
  • Failing drive motor
  • Damaged wiring harness to the motor
  • Main control board fault
  • Heavy vibration loosening the motor plug

How to fix Frigidaire E52 — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Balance the load
    Stop the washer, redistribute the clothes evenly around the drum, and remove a few heavy items if the load is huge. Unbalanced loads shake the machine hard enough to disturb electrical connectors.
  2. Power-reset the washer
    Unplug the washer for 5 minutes, then plug it back in and run a short cycle. This clears a false tachometer fault from a glitch or a momentary loose connection.
  3. Level the washer
    With the washer unplugged, check that it sits level and does not rock. Excessive shaking loosens the motor plug over time. Adjust the leveling feet until the machine is stable.
  4. Call a technician for motor testing
    A returning E52 means the tachometer, motor, or its wiring needs testing with a meter. The motor plug and sensor are inside the cabinet, so this is technician work.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • E52 returns after a power reset
  • The motor hums but the drum never turns
  • The motor wiring connector is damaged
  • The tachometer or motor needs replacement

Frequently asked questions

Can the washer run without the tachometer signal?

No. The tachometer tells the control how fast the motor is turning. Without that feedback the control cannot run the motor safely, so it stops.

E52 appeared once and never came back. Should I worry?

Sometimes a single glitch or a heavy vibration event triggers it. If it was a one-off, the reset clears it. If it returns, the sensor or its wiring is failing.

Can unbalanced loads cause E52?

Vibration from unbalanced loads can work the motor connector loose over time. Keeping loads balanced protects the connector.
