Hi i have hot water on my glow worm 30 cxi, but when the central heating starts up , it runs for about 20 seconds then stops, there is no fault signals and the pressure is fine, any ideas thanks paul

are you sure the roomstat is turned up? The display should show temp in deg c when in htg mode and pressure in bar in hw mode.
 
So the clock is set to on, the roomstat is turned up? A quick test to check if it's the boiler or the external controls is to link out the roomstat 24v connection on the back of the fold down fascia. If your heating then works I'd be checking any clock/roomstat and wiring. If it doesn't I'd be looking at the diverter valve motor and cartridge.
