How to Fix Bosch Washer Error Code Er:09:

  1. Unplug the Washer:

    First things first, ensure your safety by unplugging the washer from the power source.

  2. Check for Loose Wires:

    Examine the connections on the control module and the motor control module. If you find any loose wires, reconnect them securely.

  3. Inspect the Wire Harness:

    If the connections appear to be fine, inspect the wire harness connecting the control module and the motor control module. It’s possible that the harness has become damaged or worn.

  4. Replace the Wire Harness:

    If you discover issues with the wire harness, replace it with a new one. A damaged wire harness can hinder communication between the modules.
