David,

The fact that you're getting a little burst of domestic hot water suggests that the boiler is capable of circulating hot primary loop water through the heat exchanger, but doesn't necessarily do so when it needs to.

What seems to be lacking is a recognition that domestic hot water is now being drawn off, and that the boiler needs to fire up and divert the primary flow through the heat exchanger.

A good place to start might be the flow switch (usually in the bottom of the boiler, where the cold water supply comes in) or the electrical connections to it.

Have you topped the system up with water? The pressure gauge should be showing an operating pressure of 1.5 Bar in the green section.

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.

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.

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.

Thermo Compact Vaillant Boiler


the thermocompact is a non-condensing model, and should be o.k to fix, you do not need a cylinder as is a combi model and would provide hot water on demand!

Hi,i have a vaillant turbomax combi boiler,the radiator side is working well but when running hot tap the boiler kicks in for about 5 seconds ,hot water starts to flow then boiler cuts out,water runs cold...


Which turbomax, as there a two different models. The more modern one, with the brass CPL diverter valve, located at the front left of the boiler, was very prone sticking & jamming, this would restrict flow through the hot water circuit in the boiler, and cause cycling. Vaillant actually modified the diverter. You can identify, if it is the old type, as there is a very small hole in the middle of the diverter on the old ones, probable no more than 1mm-2mm wide. The modfied one, is much bigger approx 5mm wide. If old type, replace as this usally sorts the problem

My parents have a Vaillant Ecotec 831 boiler. Has continually broken down ever since it was fitted nearly 2 years ago. The guy who fitted it keeps coming out and it works for a few days then packs in...


Get vaillant to look at it. It could be installation fault. Their advise is impartial and they can advise if boiler can be repaired.
