Hi,
Im having trouble with my Modena 80e boiler, it has been tempramental for a while.
Problem is, When cold the boiler operates normally both CH and DHW. It will run for around 10-15 minutes then cuts out. Resetting brings the boiler back on but for around 5-10 seconds.
I have replaced the venturis in the fan, cleaned the fan and flue thouroughly.
On one occasion I turned on the DHW prior to resetting, the boiler remained on for as long as I needed Hot water. After turning off the Hot Water the heating came on perfectly for around 10 minutes then cut out again.
I have swapped plugs on the two thermistors just in case one was faulty, this made no difference.
I have flexed the PCB (safely!), no difference.
Any ideas would be greatly appreciated.
Thanks
Darryl.
