Sometimes we have hot water, sometimes we don't! ferroli 80e boiler?

I have the same boiler as yours and it is complete rubbish. Problem after problem. The issue of the boiler needing to be reset all the time was cured by a boiler repair man - he adjusted some hot water sensor, didn't need to replace anything so just the cost of the call out. The best advice I could give you would be to take out boiler cover with someone. It will easily be cheaper than replacing everything every couple of months as I have done over the past couple of years. I could have replaced this boiler several times over for the cost of all the repairs.
