Nest heat link not responding

[Swhoward1990]

Hi,

thermostat and heat link were working perfectly until today.

Heatlink now has solid yellow light and H71 error on thermostat. won’t go into manual mode and won’t respond to pressing 20 seconds for hard reset.

Any ideas??

Hi @Swhoward1990, thanks for reaching out. I'm sorry to hear you're experiencing this issue, but we'll sort this out together. Let's start with a few questions:

Did the issue happen during installation or after installation? Was it installed by a Nest Pro or by a regular installer?
Does the boiler activate when calling for heat by pressing the Heat Link's button to activate Manual Mode?
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?
