I have a boiler made by "Main" which is playing up and wondered if someone could provide some help. It is 12 years old
- I set the heating to "ON" from my Hive app
- The boiler fires up (Power light and flame light are both lit) and heaters heat up
- After about 45 mins or so the boiler switches off completely (as if there is no power). All the lights go out - Hive still says "ON"
- After about 1.5 - 2 hours the boiler comes back on again and heats for about 45 mins then goes off again
