Question about Heating & Cooling
SOURCE: Vaillant combi boiler problem
when the tap is turned on and the water light on the boiler doesn't this means the diverter valve is not operating it could be down to low water pressure in the house this can be checked at the cold tap in the kitchen. if there is plenty of pressure then it could be the diagphram in the diverter valve is worn or split. the diagphram is only a few pounds but it depends on the engineer you get as to how much money he wants to fit it.
the egg timer symbol (or two pyramids together) is an ignition indicator turn off and on again to see if it will fire with the tap running. reset the boiler with the lower right hand control knob.
