Main Eco 30 Combi boiler no heating

Hi All

I have a Main Eco 30, it is a Combi boiler and central heating doesn’t work (hot water works normally). It worked fine last season. It is fitted with a wireless thermostat, and it looks for me that it receives the signal… but then all happens is some clicking noises and pump tries to power up- but no success. Can someone help me?


Hi Tim

It looks like you have a problem with either the diverter valve or the thermostat itself. For replacing diverter valve you will need to call a local gas safe person. It’s not one of do-it-yourself tasks.
