What Does Error E23 Mean?

The E23 error code on your Simpson Washing Machine signifies a drain pump triac fault, indicating a malfunction in the drain pump circuit of the main PCB. This issue often results in the washing machine failing to drain water and may produce unusual noises during operation. If this error occurs, the wash cycle may not complete due to the inability to activate the drain pump.

Common Symptoms:

  • Error E23 displayed on machine panel
  • Drain pump circuit failure / drain pump not operating
  • Wash cycle may not complete due to inability to run drain pump
  • Diagnostic mode entry reveals E23 code tied to drain pump triac fault

Possible Causes

  • Main PCB drain pump TRIAC failure (high)
  • Faulty or open drain pump (medium)
  • Damaged wiring between main PCB and drain pump (medium)

How to Fix Error E23

DIY Fix Basic Inspection and Safety

  1. Turn off the washing machine and unplug it from power.
  2. Check for visible signs of water leakage or external damage.
  3. Ensure the drain hose is not kinked or obstructed.

Technician Only Drain Pump and PCB Diagnostic/Repair

  1. Measure the resistance of the drain pump windings to check for proper continuity.
  2. Inspect wiring harness from the main PCB to the drain pump for any physical damage or loose connectors.
  3. If the drain pump motor is faulty, replace the drain pump assembly.
  4. If the pump checks out but E23 persists, replace the main PCB or perform PCB triac repair if skilled.

Parts needed: Drain pump assembly, Main PCB board, Wiring harness/connectors

🛑 When to Call a Pro:
  • If the error persists after verifying pump and wiring connections.
  • If visible electronic board damage is observed.
  • If you are not experienced with mains‑level electrical diagnostics.
