Conventional vented system, the pump isn't running. I've removed the vent plug and cleaned the debris out - shaft was turning freely. There is power at the pump and I've tried tapping it with a hammer.
The only other possibility other than replacing the pump, is that the capacitor has died. The system has been noisy on start up occasionally over the last couple of weeks with hammering and boiling over into the header tank, although the pump usually started. The pump is a grundfos UPS 50-15x18. Any thoughts gratefully received. Thanks
