I have an error code 3 on my boiler which would indicate a fan or flue problem.
The fan was recently changed as well as the main control board. when the front cover is removed from the boiler it works fine but as soon as it is replaced it cuts out as if it is being starved of air.
Anyone able to shed some light or ideas.
THE PROBLEM IS THE FAN AIR PRESURE SWITCH IS NOT OPERATING CORRETLY USUALLY WE REPLACE THIS WITH FAN HOWEVER ALSO CHECK VENTURE PIPES CONNECTING TO AIR PRESURE SWITCH AND MAKE SURE CLEAN AND NOT BLOCKED
