Hi can anybody help,i have a vaillant combi boiler and i cannot turn the heating off on the radiators can anbody help cheers!


If you they won't go off when your timer is off. There's a possibility it's clock keeping it on although its turned off, which is fairly rare. However depending in which model of Vaillant you have, if your boiler has a hot water pre-heat on it. Some models which have this the diverter was prone for sticking thus leaving the port for the radiators open when in hot water mode.

check to see the time clock is set with the clock symbol. there are three settings on analog clocks I , O and clock the I setting is constant running, the O setting is off and the clock setting is timer.

Clock on comi boiler


it may be the preheat setting on the boiler for the hot water circuit. do the radiators get hot when the boiler fires up with the time clock off ? if not then there is nothing to worry about if it is only on for a short time.

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.
