:cry: we have a Baxi 133he combi and it has just started to cut out when we have a long shower . we have to wait about 1 hr before the reset flashing light will go out . problem sheet saying it may be over heating , any thoughts
 
It may well be overheating as a result of the secondary heat exchanger being blocked.

It really needs a thermal survey to positively diagnose that.

Your combustion door seals have failed causing the fan over heat stat to kick in.
