Hi our 2008 sime 102 has a fault. when, say, filling a bath, the boiler works normally i.e. divert valve operates micro switch, fan & pump starts, pilot lights and crosslights main burner. hot water flows.
after about a minute the boiler shuts the main burner off, whilst micro switch, pilot, pump and fan are still on. water runs cold then after 20 seconds the main burner relights. this cycles until water is shut off. about 4 years ago i replaced the diaphragm. It has had a weep for some time from the valve, so i fitted a new assembly which has cured the leak, but not the DHW fault.
Help?
Thanks
