Glow worm Compact 100e problem

[Goldwinger]

When I turn the boiler on, the hot water demand light illuminates even though there are no taps open? As this model puts water before heating, I can't get the heating to work. Very cold, need help please!!!!

Sure it is the demand light and not the selector light ,maybe on hot water mode only,if so change so light in lower section
