: i have a 5 year old ferroli optima 901.
: the boiler will supply hot water one day and the next day nothing,
: the heating system seems to be working ok.
: it is a very intermitant fault does any body have /had a similar expierience.any answers would be appreciated????
check the filter in the flow switch also the restricter! low flow rate will cause the boiler not to fire properly.
