SOURCE: re-pressure Vaillant Turbomax Plus boiler

two pipes coming into boiler on right hand side have brass block valves with a small round recess. These two valves are linked with a stainless fill hose.

Inside the recess on each valve is a small slot, there is a "key" with the boiler but prob lost with the manual. The advantage of the key is its sized so you wont be poking it in the wrong place!

Using a screwdriver turn both slots throug 90 degrees, you will hear water running through. Sometimes one valve is left open so try a combination until the watert runs.

Keep an eye on the pressure gauge and dont let it get too high, if you have no idea of setting pressure head for about 1bar.

SOURCE: f22 on my vaillant boiler turbo max

Hi Guy's,
The answer is that your system is out of water pressure.
Usually there is a nob on the right under the base of the unit near to the small dial to the right of the front cover.
To enable the system to work correctly the needle on this dial should be in the Grey, about midway position.
Currently with fault F22 this will be lower to below the Grey and on the needle.
To bring the pressure back to the correct position, you need to turn this nob until you hear the water entering the system, KEEP AN EYE ON THE DIAL AND TURN THE WATER OFF AGAIN WITH THIS NOB ONCE THE DIAL IS IN THE CORRECT GREY POSITION AS MENTIONED ABOVE. DO NOT OVER FILL THE SYSTEM. I suggest you check this every six months or so.
Once this is corrected your unit will light up again.
Best of luck. Mike. N.

SOURCE: hi i get fault 28 on my vaillant boiler

F-28 is a common error for my vaillant. I have had this problem serviced at least 10 times (all under warranty). It is an ignition problem and can be connected to a number of things. I have had the starter electrodes cleaned only to later have them replaced(4 times). I just had the "panel" replaced yesterday (looks like a motherboard or electronics panel). This is the second time to have this replaced. All of these things can give you an F-28 error message. I have an atmotech pro and have had ongoing F-28 issues for two years. They are looking at venting/air issues as well to see if this is the problem. douglas

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.

Heating not working and Honeywell Thermostat Heater states that the temperature is 45 degrees celsius.


without seeing it its hard to say, the thermostat controls the boiler and/or diverter valve depending how its been wired, the diverter valve shunts the water to were its needed ie from one circuit to another if you have two therostats there is a conflict somewere, best bet to have an engineer sort the wireing out

Vaillant echoplus 837, leaking diverter valve


Replace valve or if it has the usual diaphragm inside remove valve and replace washer/diaphragm
To prevent water draining from the whole system, turn off the taps on the heating pipes located just below the boiler AND the cold mains inlet

I need to power flash a vaillant boiler. can you please help. water goes hold and cold, sometime the heating stop but the water works and vice versa. i was told by an engineering that it needs power...


Hi

Although not a PC problem, i have had this same issue on my Vaillant Boiler, the problem you are describing is not a power flush problem, you need to clean out your exisiting diverter valve or purchase a new one

The diverter valve is repsonsible for either providing hot water or providing hot water to the central heating, when this valve gets stuck in between the symptoms you have described above occur

I would also not recommned that you do a power flush yourslef as you may end up damaging the boiler and its pump

I have a Vaillant boiler Turbo Max VUW 242/1E, central heating is working but no hot water


Hi,

You have a faulty diverter valve, this is a fiddly job, you need to call in a 'Gas Safe' engineer to diagnose and replace this

I hope this helps

Vaillant boiler - heating OK, but no hot water.


Most likey problem is the diverter valve, not energising fully. This in turn will not move the little plastic lever arm that actuates the microswitch on the side, sending the signal to ignite.

You can buy a diaghram kit from most local plumb centres, you need to replace the diaghram and seals, don't forget the silicon grease to ensure the plunger doesnt stick. Kits less than a tenner.

You should have noticed before it stopped working completely the water had reduced in temperature before the weeks it failed.

To make sure it is a diverter valve fault, depress the microswitch if you can, when the hot water is flowing and hey presto the demand for hot water light should shine.

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,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
