Nest thermostat 3rd gen not starting boiler

Hello, I have 2 3rd gen nest thermostats with heatlinks. Both have been working perfectly for the last 6 1/2 years, but today 1 of the heatlinks is no longer starting the boiler, either by the thermostat or the heatlinks button. The other is still working normally starting the boiler for heating and water. 

I have done a factory reset and it still does not work. I hear a click when it commands heat and when it stops but nothing from the boiler . 

any ideas ?

My Heatlink has just stopped working. No LED or anything. Checked power/fuse and ok. Looked on NEST support page and it says that a small number of people are experiencing problems with gen 3 Heatlink. It’s booked me an appointment for Friday for a free replacement. 2 days without heating and water ahead now 😒
