Dont know much about the Alpha but on the Baxi have you checked the thermistor above the overheat stat?

electrode and lead ain't gonna break the bank

BTW you are in RGI territory

for some reason people on here don"t like you trying to fix your fault in these times they would rather see you being ripped off.........i"m no gas engineer i not that lucky they are very special people but if the pump is running aps sw fan is running boiler cuuting out try unscrewing the thermistor which is sat above the safety stat ( on a baxi) and remove it from the pipe but still have it connected and see what happens.........

turn off boiler and replace thermistor whats the big deal all you need is a 13mm spanner and half a brain!!!
On the 80 eco you dont even have to drain the boiler down!!!

Hi thanks for all the replies ive ordered a flame electrode would the thermister cut out that quick when cold and is it the one directly under the overheat stat and I would have to drain the system as its screwed in
thanks

[snb]
