Hi, Nest thermostat come up with an error H71. I’ve checked the heat link and it seems to be dead, no light at all. There’s power going to it and my boiler, and there is hot water but no heating. I’ve tried resetting and restarting it, switch off power for few minutes and still nothing. Nest has been installed along with a new boiler just under a year ago. Please advise.

I've got a replacement. You can either call or contact online.

There is micro USB connector under Heatlink cover, try to use mobile charger to connect to that USB port and power Heatlink that might work in the short run while waiting for replacement.

I have a similar problem. Previously working without issue and now nothing. No lights, no response. It has power, but I now have no heating in my house due to premature failure of an expensive piece of technology

Telephone the google support line as per their website. It will still take a lil while but they will check details n arrange replacement via courier

I've contacted Google via Twitter and got quick response, however then been referred to senior management team to review and possible replacement. However, 7 hours since last contact, all quiet and house is getting cold, not ideal with 2 kids .

Hi, not sure how, apart from what was already said above. Remove top cover of the Heatlink, there is micro USB connector under Heatlink cover. I used mobile charger to connect to that USB port and that power the Heatlink while I was waiting for replacement from Google.
