Potterton PUMA 80 - pilot keeps cutting out when C.H. on

Postby tomcubi » Sat Aug 14, 2010 11:38 pm

I hope you can help with a few tips. I wouldn't like to replace this Potterton PUMA 80 which is probably 10 years old, as we'll have to renew the whole system in 6 months, but the pilot keeps cutting out.
It happens when the central heating turns on. Today I ran the hot water several times and the pilot never cut out, but suddenly this evening some steam started to come out from the air vent 5 mins after the central heating turned on.
I'd be very grateful for any advice you can give me on this.

sounds like it's over heating, possibly the pump is wearing out or the system has poor circulation
