No power to boiler after pump fault

hi chaps wondering if you could help me out, I had a call to no heating or hot water, after arriving I checked the boilermate a class l2 and found the primary heating pump was boiling hot on the head so I came back the next day fitted a new pump switched back on pump working perfect.

Went to check boiler nothing could only get heating running it through the electrical mode, checked power to boiler nothing. I'm wondering if anyone else has any idea of what it could be, I had a thought that maybe it blew a resistor on the pcb and the board is had it and that's why iv no power as if you switch it over to gas boiler it fires everything up fine like the unit thinks the boiler is on yet no power to it, if any one could help would be a life saver.

Forum seems dead you're doing as well as me regarding a response.

Is the boiler coming on, is the temp of the store at correct temp?

Yeah tell me about it I’m a young engineer so don’t come across these at all So not much experience loads of people have been on the site but like you say no one bothers :joy:

Yeah all temps are good on the unit it’s working fine in electric mode but switch to gas mode as such and no power to boiler but power to pump and other controls

Thanks for your reply
