Washer stops and displays E09, often with no drum movement at all from the start of the cycle

Safety first: Unplug the washer. Inverter circuits store high voltage; wait several minutes for capacitors to discharge before touching the module.

Step-by-step checks:

• Visual inspection: Access the inverter module (often mounted near the motor or in the base). Look for burn marks, cracked components, or a burnt smell. If present, the module should be replaced.
• Check motor windings: Disconnect the motor from the inverter. Measure resistance between each pair of motor terminals. All three readings should be similar. A shorted or open winding indicates a failed motor that must be replaced before fitting a new inverter.
• Inspect wiring: Check the harness between the inverter, motor, and main control board for damage or loose connectors. Repair as needed.
• Cooling and environment: Ensure ventilation openings are not blocked and that the washer is not installed in an excessively hot environment, which can overheat the inverter.
• Module replacement: If motor and wiring test good but E09 persists, replace the inverter module with the exact Blomberg-specified part. Due to high-voltage risks, this is best done by a qualified technician.
