My Potterton stopped producing hot water completely earlier on. Hot water is now coming from the taps, but only if the taps are full on. If I turn the taps down a bit, to approx half, the water runs cold and the burner light on the boiler goes out.
Does anyone have any ideas. The pressure is OK, and the flue or condesate drain aren't blocked.
Thanks.
