Worcester Bosch Boiler

Hi,  My Worcester Bosch 35CDi is showing an air pressure fault (light flashing).  Can you help?

Thanks

Stephen

Hi Stephen,

This could be a new problem or a problem from install.  Check that your flue is greater than 1m and ensure the restrictor has been removed.  Check that your air pressure switch is not faulty and is functioning correctly.  Check your fan to ensure it is working correctly.  Check the air pressure tubes as they may be blocked, bent and damaged causing a restriction in air flow.
