SIEMENS comes up in large blue display when mains is on, apart from the odd flicker, nothing else will work. had a look around all three pcb’s etc but can’t see anything obvious. not worked on many of these so any help would be great.

If its doing that it relates to the analogue sensor being out of its operating range or connection from it to the module missing.
If required its 182238 £23.69 + the usual.
As if you didn’t know, they don’t click when you blow down them. Usually doing this results in permanent damage to the little guy 😀
