Heatlink not working again

[Onetwo96]

Ive had my heatlink  replaced 3 times now , pretty much at the same point in the year , when the heating has been off for a few months as soon as you want to fire up the boiler and heat your home , the nest thermostat will not work . The issue seems to be that the thermostat says its heating , the heatlink says its heating but the boiler is saying no . I’ve had an engineer from Boxt sent by google twice and each time they replaced it and said the neat heat link has a known fault and has malfunctioned . I’ve now tried to get a replacement again but the person I contacted was absolute useless kept saying if the green light is on then the heatlink is working  fine and can’t be replaced totally contradicting an engineer , can someone from google please contact me to resolve this

First of all if you want someone from Google, you need to go to the Google customer services, as this is a community forum to help users.

For you to have 3 Heat Links faulty in that amount of time is very very odd.

However, do you have any lights on the Heat Link? Assuming you have one green light, what happens when you press the Heat Link button in the centre, anymore lights show? Does the boiler fire up?
