I have a Worcester 28i combi which is run by a Drayton Lifestyle LP111. The timeswitch is in the off position and hot water is readily available when you turn the tap on. My problem is that when i press the select button to change the timeswitch to timed, once or on the timeswitch then starts clicking and the display faintly flashes at the same time and the central heating doesn't come on. The boiler basically trys to fire up but then cuts out after about 20-30secs. I've replaced the timeswitch with an exact model type but the same happens again.
Please help.
