My Nest thermostat came up with a H72 error yesterday and when I’ve checked it’s to do with no power from the heat link. We have 3 thermostats and only about a month ago the same thing happened with the thermostat that feeds the hot water - I managed to get in touch with customer support and arrange a replacement, the technician who came to replace said this is a common error and the other heat links would probably not last much longer - one month down the line and another heat link has stopped working only now I can’t get in touch with customer support - can someone help please?
