Hi
My mother aged 88 has had A Ferrolli OPTIMAX HE 31 C boiler since 2008 along with new radiators COSTING £6000. The water has never been that hot and they can't seem to get the heating to come on in the morning most days. Heating ould not come on last night or water. After some fiddling water is on, but flashing light says error D1. Ferrolli told us that means a delay and as she did not have it serviced last October the 5 year warranty is no good and she will have to pay an engineer to come out. I do not think there is anything really wrong, just complex boiler.
Any ideas on what to do, manual is so complex.
