Heatlink h71 error. Dead unit?

Ianto99 — Sun, 27 Mar 2022 12:39:04 GMT

Heatlink not working. Installed Dec 20.

worked fine last night.

nest showing error h71 this morning.

Heatlink no lights, no response to prolonged press etc.

presumably a dead unit that can be replaced under warranty? Preferably before it gets cold later this week please!

Exactly the same has just happened to mine today too. I've gone through all the trouble-shooting steps suggested and still unresponsive, dead heatlink. As this controls not just my heating but my hot water, I can't shower or anything until it's replaced, does anyone know how to arrange that? Thanks

Thanks for letting us know @Ianto99 , @sbirks23

Could you tell me please when did the situation start occurring first and when was the thermostat installed?

Also, please answer to the following questions:

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?
If yes, how long was the power off for? (Be specific.)
Could you tell us please if you've checked on the breaker switch and fuse box?
Any blown fuse in there? Have you tried to turn the breaker switch off and on again? Any difference?
