What Does Error E52 Mean?

The E52 error on your Simpson Washing Machine indicates a malfunction in the motor drive unit, typically due to issues with the motor brushes, tachometer, or wiring. When this error occurs, the washer may stop mid-cycle, fail to spin, and produce unusual motor noises. Ensuring that the load is balanced and checking for obstructions can help, but further inspection may be necessary.

Common Symptoms:

  • Washer stops with E52 displayed
  • Motor fails to spin despite commands
  • Possible motor noise before fault appears

Possible Causes

  • Worn motor brushes (medium)
  • Faulty motor tachometer or motor wiring/connectors (medium)
  • Main PCB issue affecting motor signal interpretation (low)

How to Fix Error E52

DIY Fix Basic checks before technician call

  1. Power off and unplug the washer
  2. Open the lid and check for obstructions around the drum
  3. Ensure load is balanced and not over capacity
  4. Try a reset by unplugging for a few minutes and restarting (only basic reset)

Technician Only Inspect and repair motor/tacho circuit

  1. Disconnect power and access motor assembly
  2. Inspect motor brushes for wear; replace if worn
  3. Check motor tachometer sensor; measure resistance or signal output
  4. Inspect motor wiring harness and connectors for damage or corrosion
  5. If motor/tacho tests normal but fault persists, test main PCB motor drive and signal circuits

Parts needed: Motor brushes, Motor tachometer sensor, Wiring harness/connectors, Main PCB (if needed)

🛑 When to Call a Pro:
  • If motor brushes, tacho or motor wiring checks are inconclusive
  • If main PCB diagnosis or replacement is required
  • If unfamiliar with motor electrical troubleshooting
