A property I am working on to rent out has one of these boiler in and has been working fine. Today I went to the property and turn boiler on and even thought there was a demand for heat and hot water the boiler just does nothing. No C or anything on the boiler. I tried resetting it and also turning on and off but n joy. I kept hold of reset and error Hb comes up. I phones ideal they said this is normally the reset button stuck but its not. I am thinking the board had just gone on this boiler. Can anyone help out on what it could be before I give ideal £310 ?
Thanks
