H72 Heat Link no lights

[Perag]

Like a few other posts I've seen on here, heatlink is dead, thermostat shows H72 error code.

I have read the other links and carried out procedures as advised but no luck

Does anything happen if you press its button for 30 seconds? Nothing

In some cases the boiler will have an additional isolation switch which can turn off the power to both the Heat Link and the boiler. Can you try switching that off/on again to see if anything changes? Done – no change

Make sure the breakers are on or the fuse board hasn't tripped. Reset everything – No Change

Moreover, to have a better view over each of your cases, please help us with some answers:

How often do you experience the issue? Once

How long has your thermostat been installed for? Just over a year

What colour is the Heat Link LED? No Lights

What is showing on the Nest thermostat display? H72

Have you had any power cuts recently? No

Have you had any work done on your electrical or heating systems recently? No

How many zones are present in the setup? One

Is there power present to your boiler? Yes

Hi George, thanks, I was able to contact via phone.  Have an engineer booked, but for Monday.  Gonna be a cold weekend for us.  I was happy with the service on the phone.  Not pleased that it is ok to leave is without heat/hw until Monday.

I'm glad to hear that you managed to get in touch with our colleagues. I'm sorry you couldn't book the installer earlier, I understand the situation and I know it's not easy to be without heat, especially during this period.

Hi there, @Perag. I'm just following up on the previous message. All good? Do you still need our help? Keep us posted.

No thanks.  Engineer turned up this morning and fitted a new heat link. So far everything is up and running again and the house is warming up and the water is heating up.
