I have a Worcester greenstar 24i junior combi boiler and the timer is not switching off. If the boiler/heating is on and then goes to timer, it remains on but when the the 'off' time is reached, for the heating to swich off- it doesn't. what to do?
I have exactly the same problem. I have HW, no problems. The timer keeps time, it just won't click on or off so only CH when on constant. I'd appreciate any help please.
