no LED on heatlink and H71 error on app

paulmackellar — Tue, 24 Jan 2023 01:00:05 GMT

I'm getting no LED showing on my heatlink and error H71.

In the app I'm seeing this is a common issue and to visit BOXT to get in resolved, however I'm from the Isle of Man which doesn't seem to be covered by my post code.

Any idea how to proceed?

Hi there, Paul! I'm sorry to hear about this, but I'm here to help. We'll have to do some troubleshooting and if the issue doesn't get remedied we'll send you out a new Heat Link. Could you please answer the following set of questions, and try the troubleshooting steps?

What type of Nest Thermostat do you have?
Are you seeing any wiring report or code on the thermostat and/or the app?
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 zones are present in your setup? Meaning how many thermostats do you have.
Were there any power outages lately?

Check if the breaker switches are set to on.
Turn the breaker switches off and on.
Turn on manual mode by pressing once on the button of the Heat Link.
