Bosch Washer Error Codes

Bosch Washer Error Code Er:05 and Er:06

Er:05 and Er:06 error codes on your Bosch washer point to a defective water temperature sensor. This sensor, also known as the negative temperature coefficient (NTC), is responsible for monitoring and regulating the water temperature during your wash cycle.

How to Resolve Er:05 and Er:06 Error Codes:

  1. Safety First: Before attempting any repairs, ensure your washer is unplugged or disconnected from the power source.
  2. Inspect for Loose Wires: The first step is to check the wiring connections to the water temperature sensor. Sometimes, these wires can come loose due to vibrations during washing.
    • Carefully access the sensor and the wiring harness.
    • Reconnect any loose wires to the sensor securely.
  3. Check for Wire Harness Damage: Inspect the wire harness connected to the sensor for any signs of damage, such as fraying or exposed wires.
    • If you find any damage, it’s crucial to replace the wire harness to ensure safe and proper functioning.
  4. Replace the Water Temperature Sensor: If the wire connections are intact, but the error codes persist, it’s time to replace the water temperature sensor.
    • Bosch washer parts are typically available through authorized dealers or online sources.
    • Follow your washer’s user manual for guidance on removing the old sensor and installing the new one.
  5. Test the Washer: After replacing the sensor, plug in your washer and run a test cycle to ensure the error codes have been resolved.

By following these steps, you can address Bosch washer error codes Er:05 and Er:06 related to a faulty water temperature sensor. However, please note that if you are uncomfortable with the process or if the problem persists, it’s advisable to seek the assistance of a professional appliance repair technician. They have the expertise to diagnose and resolve issues effectively, ensuring your Bosch washer operates flawlessly once more.
