Boiler problems

[fus]

I have a Baxi Combi instant 105E.

I have a problem where the lights on the front display go out and I get no hot water for a little while, then after a while they come back on and everything is ok. I have recently had the "board" replaced but still the symptoms persist. Any ideas ???

Ps, due to an original problem (water going hot and cold) I have had the diverter valve motor replaced as well as the diaphragm inside the diverter valve. Not sure if this has any relevance but it just seems that the boiler is generally unwell !

Thanks

Sounds like it is overheating and the overheat thermostat kicking in.
Did one similar and it was the thermistors. Replacing board was
probably a waste of time. Take a look at what happens to the temperature when running hot water or heating does it start getting too
hot.
