Heatlink is dead, no lights, h71

[Alx80]

Had the nest thermostat for a couple of years, worked fine. Got home from work today to a cold house, base says it can't connect to the heatlink, boiler & heatlink both on the same power, boiler is on, heatlink has no lights. 

Tried reconnecting with base unit

Tried turning heatlink power off for a few minutes

Seems like its dead to me.

How did you get on? I have the same issue - cold house and H71 issue on the thermostat. I have no lights on the heat link, so I think the unit may have failed.

Hello everyone,

Thanks for reaching out. I'll do my best to get this sorted for you as soon as possible.

Here are some helpful troubleshooting steps:

Press the button on the Heat Link and check if you have any lights on it
Check if the circuit breakers and the switches are set to on
Turn them off and then back on
Press on the button again and check for LEDs

Could you also help me with some answers to these questions?

How long has your thermostat been installed for?
Did the issue happen during the installation?
Is there any error on the Nest thermostat display?
Have you had any power cuts recently?
Have you had any work done on your electrical or heating systems recently?
If yes, was the power properly restored at the fuse board after work was done?
How many zones ( thermostats ) are present in the setup?

Thanks Cristian, kind of you to reach out and help.  The unit is 18 months old and as it turns out- the Heatlink unit has failed, fortunately it is within warranty.  I had my electrician check it out and he confirmed it.  I rang Google who were brilliant and they are sending me a replacement unit - within 24 hours.  There havent been any power cuts recently or previous error messages, so it is all a little strange.  However, a new unit is on its way and Google have been brilliant.  Thanks again

Hey @MikeTheBroker. I'm glad to hear that. If anything comes up, I'm only a message away.

It was dead, but still in warranty so they sent a new one within 48 hours & they paid for the Installation. Decent customer service, softened the blow a little of having no heat for 3 days in the middle of winter.
