no blue light from the bosch boiler?

is it just the fact the blue light is NOT working that bothers you?
& everything else is working
i.e. DHW & CH OK
or are you saying the boiler is completely dead & you have
NO DHW & NO CH?
because if its the first point id be prepared to put up with it
whereas if its the second point you have a major problem

if you want help with fixing your boiler
i need more relevant information
otherwise
garbage in
garbage out
