Nest heat link faulty

[nlevett]

Hi. 
The heat link box has suddenly stopped working; no light on it or anything now. We’ve no longer got hot water or heating and the thermostat has the h71 error code. 
It was purchased and installed in Dec 2020 and has worked fine until then. 
Any help on how to get this fixed please?

Thanks.

Hi @nlevett. I'm sorry to hear you're experiencing this issue, but we'll sort this out together. Let's start with a few questions:

- What type of Nest thermostat do you have?
- Did the issue happen during installation or after installation? Was it installed by a Nest Pro or by a regular installer?
- 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?
- Have you tried any troubleshooting steps before contacting us?
- How many thermostats do you have?
