Hi all. Daughter's boiler again thanks for help last year.
New problem - hot water works fine, but when calls for heat boiler starts and runs for a few seconds then stops. No error messages.
My thought is that pump is inop, so boiler starts up but then switches off when the small amount of water in the heat exchanger reaches temperature but doesn't circulate.
Would be grateful for any other ideas before I plan who to get to fix it (expensive with D&G if it is just a new pump).
