Possible Causes

Defective inverter module (on brushless motor models), Shorted or open stator windings, Loose motor harness connector, Overheating of inverter heat sink

How to Fix / Troubleshooting

Safety first: Unplug the appliance. High voltages are present in inverter circuits; proceed only if qualified.

Step-by-step checks:

  • Inspect motor and harness: Remove the rear panel and check the BLDC motor connector for secure fit and no corrosion. Inspect the harness for damage.
  • Test stator windings: Disconnect the motor and measure resistance between each pair of stator terminals; readings should be equal and not shorted to earth. Replace the motor if out of spec.
  • Check inverter module: Locate the inverter (often integrated with the main PCB). Look for burnt components or bulging capacitors. Ensure the heat sink is not obstructed by lint.
  • Module replacement: If the motor is good but E20 persists, replace the inverter/main control module with the correct Balay part. Configuration may be required.
