Hi I have the Biasi compact 28s when you switch CH on the boiler fires up for a few seconds then it pops off and displays a rapid flashing light. It does this some times for up to 12 hours repeating the problem every 5 minutes. Also when the CH is off via the timer the boiler just fires up for no reason for up to a minute then switches off. It does the second problem every five minutes for up to 3 hours some times.
I have had 2 plumbers look at it but they both said they don't know what the problem is? One said to change the valve that switches between hw and ch the other said he wants to remove and clean the heat exchanger but it might not be that?
Can any one help or should I just call Biasi?
