What a good example of the sort of problems one can get in plumbing.
Pumps can go slow , or perhaps near the right speed but without proper torque available, if the big capacitor gets weak. But how that results in (apparently) air getting into the system, heaven knows!
I once put a new boiler in (WB HF400) which cut out every few days, then less and less often. I visited but never found a cause. Then a builder added a radiator, and it did it again. They called WB, whose man could find nothing wrong, but he changed several parts, including the fan, aps and the pump. It got better immediately. Though the pump seems the most likely culprit, it's damn difficult to prove.
