Hello I have a Sime Halstead Trio combi boiler I have recently had problems with my central heating coming on when I turned the taps on so after changing the diaphram and it not fixing it I changed the Diverter valve itself and micro switch.
It has been working fine for a few days now the boiler does nothing when hot taps are turned on, the central heating works, Any ideas much appreciated thanks.
