Asko Drain pump blocked

Asko error code DRAIN PUMP BLOCKED indicates: Asko washing machine drain pump blocked; water remains standing in drum and machine halts with drain error..

The primary root cause for Asko code DRAIN PUMP BLOCKED is: On Asko Washing Machine: Foreign object (coin, hairpin, button) wedged in drain pump impeller chamber, or pump motor coil open (~150–220 Ω)..

To resolve error code DRAIN PUMP BLOCKED: On Asko Washing Machine: Unscrew front drain filter trap and remove debris. Verify pump impeller spins freely by hand. Measure coil (~150–220 Ω).

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Asko code DRAIN PUMP BLOCKED persists, the physical component causing On Asko Washing Machine: Foreign object (coin, hairpin, button) wedged in drain pump impeller chamber, or pump motor coil open (~150–220 Ω). 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.
