D2 is not a fault what that means is delay and 2 refers to CH which means the boiler has gone into standby mode. you need to check that your CH circut is open, there is a filter on the return valve into boiler make sure this is not blocked. If this is blocked the water is just going though the boiler by-pass so then the boiler thinks its up to temp. hope this helps
