Tbh you will be better getting a gas safe engy in as it may need the cover off to your boiler, for this you need to be gas safe

Agree I have had the cover up and opened the controll box with the boiler off. Didn't know you need to be gas safe reg for tht.

The boiler has been fitted by a gas safe reg plumber

That's fine however the cover forms a combustion seal and you have no means to test it's back on properly

As above. This isn't a diy job.
