Baxi 105e no heating

[boringfrog22]

Hi all, have an intermittent problem with my Baxi 105e. When heating gets up to temp and the boiler stops burning it won't come back on. No flashing lights, reset boiler and turned off at the mains and it came back on.

turn off at mains helps...v odd..

no flashing lights...no fault code...unusual too...could be pcb.thermistor.thermostat...but you do usually see flashing lights when internal components go tats up

Thanks @durhamplumber. Not 100% sure but when I closed the front hatch on the Baxi all the red temperature lights went out, I opened the hatch straight away and they were on, could be imagining this. .
House is empty as tenant moved out but going up again today see if it does it again.

all lights going on and off sounds like pcb fa

Thanks again @durhamplumber It has had one PCB in it 16 years lifespan, so not too bad.

they are good boilers and 16year old is worth a new pcb in my opinion.
