Have I killed my 'boiler'? Help please.

[tam203]

Thanks for all the help so far.

I've had no luck finding a fuse which does seem odd?!

Not checked with the multi meter at the boiler but since it's monday I'm going to phone the profesionsals now...

There is 230 V entering the boiler.
I can't find any dead fuses in the boiler (lots of intact ones).
Woried I've killed the PCB, surly it's not that easy to distroy?! Oh dear.
Thanks for all the help.

230v at the pcb? If so, then it’s possible that the pcb has indeed failed. Anything else carried out recently, eg a new electric meter, or anything else?

Can you post photos of the front of said boiler/ashp?

Entirely possible the boards popped...if you put the N from the old stat onto NO on the new one you've railed 230vac down the neutral

Just to conclude this thread.

It was as @flameport suggested.

In the end the electrictian found a fuse burried somewhere deep in the heat exchanger PCB that I didn't find, replaced it and hey presto fixed in 5 minutes flat (they also then wired up the thermostat for me).

Thanks for all the help.
