I'm currently having problems with my nest 3rd gen thermostat.
My issues are;
Nest does not tell the boiler to switch on hot water for my tank system. On the app and the nest itself is orange indicating that the water is heating up. But when i go to the boiler it does not fire up.
I can hear clicking on the nest heat link however nothing happens.
My second issue is. When i switch on for central heating. The boiler fires up, as it should. However when the desired temperature is reacher the nest doesnt tell my boiler to switch off. This leads to the boiler constantly heating up my home. Which i do not require. On the app and the nest it shows that the heating has stopped, however this is not the case.
I can hear clicking noises near the heat link.
Please help
