Have a problem with my ikon 23t combi boiler. When you turn on the boiler it comes on, the heating and you get got water but the boiler runs 100% all the time and can't be set to summer mode and can't be left on the timer. In fact once you turn it on at the wall it's on!!! Once up to heat the boiler fires up for a few seconds then shuts off. The house gets too hot so have to turn the boiler off, then on again etc!! I'm 100% convinced its an electrical problem but no idea what. Any ideas would be gratefully appreciated.
if of any help maybe your boiler manual is listed here ..
They are a Glowworm product and from past experience i had 2 homes with their boilers in and both were conastant hassle, in the end replaced them with Vailliant's , but i know its a dear fix, but Glowworm are the cheaper end of the market the gas engineer told me.
