Ongoing problem with CH

[huesey1974]

Hi,
I have a problem with my myson apollo boiler, the problem is that when i turn on the heating at the programmer it turns on, however later on if i turn it off the boiler keeps going.I have to turn it off at the mains to stop it.The hot water works fine.Also if i turn the CH on whilst cold and give it a few minutes then turn it off it goes off, it seems to only stop working while at heat.I have replaced the 3 way valve CH pump nad also roomstat plus programmer but with no luck.Any ideas

Cheers

would have been cheaper to call someone in than to change all those unnecessary parts.

e-bay = buttons, plus they are thirteen years old so always good to replace these things now and again.Also cheers for your input it really helps.
