Nest thermostat lost power

[Pompey79]

Hi, 

I have lost power to one of my Nest thermostats. I have 2 heating zones, typically it's the one that controls the hot water that has failed. 

The heatlink has no lights on it, I have tried the normal turn of the power and restart to no avail. I have checked the power to the heatlink, it has a 240v supply so appears to be a failure of the heatlink. 

It's just over 2 years old and appears to be a common issue. Any ideas how I go about getting a new one? 

Thanks

Thanks for letting us know  @Pompey79

Could you tell me please when did the situation start occurring first and when was the thermostat installed?

Also, please answer the following questions:

Are there any lights on the Heat Link? Does the boiler activate when calling for heat by pressing the Heat Link's button to activate Manual Mode?
Are you seeing any wiring report or error on the thermostat and/or the app?
Have you had any recent power cuts in your area? If yes, has the power been restored?
Have you recently had service or maintenance on your electrical, plumbing, or heating system?
If yes, how long was the power off for? (Be specific.)

Could you tell us please if you've checked on the breaker switch and fuse box?
Any blown fuse in there? Have you tried to turn the breaker switch off and on again? Any difference?
