Boiler wont turn off

[stressederic]

Hi Thanks for reading the post

I have Glowworm flexi com SX condensing Boiler

With Mains pressured Hot water system (mega flow)

This morning when I got up I tried to switch the heating off Via the Timer..

Nothing Happened... The Heating and Hot water are on continuous,

The only way I can stop the Heating and hot water is to turn the mains switch off at the boiler.

Is this a valve problem? Have tried manually to move the valve on the Heating but nothing happens.

There seems to be 2 diverter valves 1 for Heating 1 for hot water


Your Help would be greatly appreciated

It could be that one of the valves' switches has stuck ON. Only way to be sure would be to disconnect and check for continuity, or live signals.

Not being electrically minded I think I may need to call someone one in.

I thought it might be a case of just replacing the valve (which Is within my capability)
