Baxi E160 Fault

Baxi E160 Fault

The Baxi E160 error code specifically points to a fan fault within the boiler. The fan plays a crucial role in ensuring safe operation by expelling harmful combustion gases out of the boiler and drawing in fresh air for the combustion process. A fault with the fan can affect the boiler’s ability to operate safely and efficiently, triggering the E160 error code as a warning.

Causes of the E160 Error Code

  1. Faulty Fan: The fan itself may be malfunctioning due to wear, damage, or electrical issues, preventing it from operating at the correct speed or running at all.
  2. Blocked or Restricted Airflow: Obstructions in the airways, flue, or external vents can restrict airflow, affecting the fan’s performance.
  3. Electrical Connection Issues: Faulty wiring or loose connections related to the fan’s electrical supply can lead to operational failures.
  4. Control Board Problems: The boiler’s printed circuit board (PCB) controls the fan operation. A fault in the PCB can miscommunicate or fail to properly control the fan’s function.

Troubleshooting and Resolving the E160 Error Code

  1. Inspect for Obstructions: Check the flue, air intake, and any external vents for blockages that could be restricting airflow. Remove any obstructions found, if safely possible.
  2. Listen to the Fan: When attempting to start, listen for the fan. A silent fan could indicate a power supply issue, while unusual noises might suggest mechanical faults.
  3. Check Electrical Connections: Ensure all electrical connections to the fan are secure. However, it’s advisable to have a professional handle electrical inspections and repairs.
  4. Reset the Boiler: After checking for obstructions and ensuring connections are secure, try resetting the boiler to see if the error clears. This can sometimes resolve temporary faults.
  5. Professional Diagnosis and Repair: Given the critical role of the fan in boiler operation and the potential complexity of the fault, it’s best to consult a Gas Safe registered engineer. A professional can accurately diagnose the issue, whether it’s with the fan, electrical connections, or PCB, and carry out necessary repairs or replacements.
  6. Regular Maintenance: To prevent future occurrences of the E160 error and other operational faults, ensure your boiler receives regular professional maintenance. This can help identify and address wear and tear, electrical issues, and airflow obstructions before they lead to significant problems.


The Baxi E160 fan fault error code signifies a problem that requires immediate attention to ensure the boiler’s safe and efficient operation. While some preliminary checks can be done by the homeowner, diagnosing and repairing fan-related issues typically requires the expertise of a Gas Safe registered engineer. Regular servicing can help maintain the fan and other boiler components in good working order, preventing future faults.
