Bompani E03

Bompani error code E03 indicates: Water is not draining from the drum at the end of a cycle..

The primary root cause for Bompani code E03 is: The drain filter or drain pump is blocked with debris, the drain hose is kinked or blocked, or the drain pump has failed..

To resolve error code E03: Turn off the machine. Carefully drain any remaining water and clean the drain pump filter. Check the drain hose for obstructions. Inspect the pump impeller to ensure it can turn freely.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bompani code E03 persists, the physical component causing The drain filter or drain pump is blocked with debris, the drain hose is kinked or blocked, or the drain pump has failed. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Drain Pump Motor Stator Coils across Across pump motor spade terminals (L-N unclipped). Expected nominal reading is 160Ω–220Ω (Sync 230V) / 20Ω–45Ω (3-Phase BLDC). Tolerance: ±10% balance. Insulation resistance between coil and motor chassis must exceed 20MΩ..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
