Hello all, This forum proved to be very helpful 6 months ago when we were facing issues with our boiler where it showed error F1 and the pressure kept dropping. We contacted Ideal and they came and fixed the boiler where in the heat exchanger had split. This morning however there was no hot water again and we checked the boiler and it is showing F1 error again. Only this time, the pressure has not dropped from the usual 1.2!!! The only thing different in months is we had our hearing on yesterday. We have called Ideal in again but they will be here only on Friday. Anyone have any advice please or experience on what could have gone wrong? Tha ks!
