Check to see if your pressure relief valve is partially open. This is about all it could be unless you are losing flame under the boiler vessel.

Combi boiler will not fire up on heating or hot water. pressure gauge reads approx 2.1 bar red light lit on panel


Hello
The water pressure should be 15 to 12 psi.If your at 2.1 there is a problem with your auto fill valve.

Which means the boiler is shut down on low water.

The auto fill valve is connected to your incoming cold water from the home,shut it off and check the screen inside for dirt or rust,you may need to have another one installed.

Hi i have a combi boiler that the pressure is falling and combi turning off. I filled the pressure back up at 5pm last night and when i got up at 6am this morning it was back off with no pressure any...


when the heating is on does the pressure rise? if it goes up you will need to recharge the expantion vessle and you mite need to change the prv.

Repressurise Potterton Performa 24 boiler


hope this is helpful. On my potterton 24 combi boiler it is the valve that sits the lowest, with a slight indent in the black tap. if you turn this for a short period you will hear a hiss and the pressure will quickly build to the desired pressure, when you can them turn the tap back off.

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.

My aristion DIA 20-24 combi boiler keeps tripping the over heat thermostat button located under the main control panel maybe 5 times a day seems to be getting more frequent


hi,

just check your water supply of your aristion DIA 20-24 combi boiler if is in constant pressure. not properly circulated water supply can cause overheating.

and manuals can help us also in proper checking. at the link below please check this out if you don't have.

Vokera option combi boiler seems to increase in pressure until it opens the safety vave ,only when heating is on !


check to see if the expansion tank is completely full of water or isolated from the rest for the system. If full it needs replacing, if isolated (valve turned off to it) then turn it on. When a hot water heating system cannot allow for expansion then the pressure will increase when running until the saftey opens.

I have a Baxi Combi boiler and want to add new TRVs to the radiators. Do I need to drain the system or can just turn off all the radiators and hope not much water escapes. How do I add new inhibitor...


You will need to isolate the boiler from the radiators because there is an auto feed valve that will continue to allow water into the system if the pressure in the boiler drops. There should be some valves off of the boiler that will allow you to do this.

I want to take a sink unit out. This means I have to turn off the cold water mains and hot water. I have a Worcester combi boiler and am not sure how to turn off the direct hot water . Can you help


Under the sink itself there should be shut-offs. To turn off the water to your boiler, first turn the power off to it at the breaker box. Then on the boiler itself, there will be some valves. One of the valves will be located in the copper line that comes from your water meter. Turn that one off. If you want to turn off the water to the whole house, right next to the water meter there should be a valve. Turn it off and open all faucets to ensure the water is off. Reverse this procedure when establishing water pressure again.
