Ariston 23 mffi

Hi all,

have had this combi boiler in place for 9 years and i know its old but cannot afford new installation. In the last 12 months i have had replaced professionally
Fan
Flow Switch
PCB
PRV
Pump
Divertor Valve
Temp sensors and a power flush for luck

We still have a problem, Hot water works in both economy and C when CH is totally turned off by built in timer. Central heating will work when first turned on and all rads heat up, after approx 15 - 30 mins but sometimes longer and the CH is in demand again it does not fire and the reset light appears, doesnt matter how many times you extinquish the reset light neither CH or HW will work. we have to leave it for anywhere up to an hour before it all comes back on for the same problem to happen again.

Any advice would be welcome..

Get a heating engineer instead of parts would be my advice. Look after several customers with this boiler- NEVER had to change parts like your guy is doing

My guess is a £20 part and ten min job! Sounds like your boiler is either overheating or thinks it is which is why it take a hour before it works again
