Hi There - I’m getting error message H71 - but heat link is dead - no lights and unable to reset. Have had no power/electrical/heating issues or work done. The set up has been working fine for the past 2 years and I have no idea what has happened. Power to the boiler is fine - and have hot water.

Hi, my heat link died last night, power to the unit is fine but power from unit has stopped, no lights and the base is showing the no power error

Hi There, Exactly the same issue with my heat link has happened today. No power at all, totally dead. I can get power to the heat link by using the small usb Jack on the front under the main cover and the main thermostat now connects to the heat link
fine, but no signal is being sent to the boiler to activate the heating. Either via the app or pressing the heat link button….
The system is a little over 2 years old so this is very disappointing from Google….

Hi @msmith585
Yes, that’s exactly the same as me, even down to being just outside the warranty period! I also agree about being disappointing for Google because all of their kit I have had has been really good quality and lasted well. But I can only assume there has been a dodgy batch of Heatlinks as there are several cases reported in this forum. However, they’ve recently sent me a new one so that’s good, but it’s taken about 5 weeks and required persistent chasing to get it, so my advice is hang-in there and don’t give up. Other than the Heatlink failure I’ve been really impressed and happy with the Nest system, but just a bit in two minds at the moment. Good luck 🤞

Hello @msmith585
I'll do my best to help you sort this out. Please try the following:
1. Restart the Heat Link:
2. Restart display:
3. Try to connect the thermostat with the Heat Link again.
Let me know how it goes.

Hi DragosC, I have tried all of that and nothing is working. The heat link only gets power when used with the usb Jack. As soon as I remove this it is dead. Also, even with power the wall controller connects to it fine, but the commands are not being sent to the boiler itself.
