Vokera 24

[pollywall]

I am having a problem with my Vokera 24 combi. It cuts out immediately after starting up and registers a fault code 3 which is the fan or flue.
The main board and fan have been replaced.
When the front of the boiler is removed, it will run but as son as the air tight cover is replaced it cuts out again.
Anyone got any ideas?

Cheers

check the flue, venturi and the air pressure switch.

This sounds like a desperate and very expensive attempt to replace parts without being able to properly diagnose the real fault.

The parts that Nick has mentioned are all part of the combustion chain and safety devices and should only be worked on by a competent person who would usually be CORGI registered.

Fan venturi blocked as nick says.
