Why does my Vokera boiler losing pressure?
Pressure loss may be caused from a leak in the pressure relief valve, an issue in the expansion vessel, air in your system, or a leak in the heating pipework itself. 99% of the time, a boiler losing pressure is a leak.
How do you reset Vokera?
To reset your Vokera boiler, move the mode selector switch to the ‘OFF/RESET’ position and then move it back to either ‘hot water only’ or ‘heating and hot water’. Should this reboot get your boiler working again then you’ll know because there will be a constant green light.
Why is my vokera combi boiler losing pressure?
I have a Vokera combi boiler that has been losing pressure (over a few hours from 1.5 bar – 0bar). I have released the pressure by bleeding a radiator, and then checked the expansion vessel via valve and it was totally empty. So i topped up the expansion vessel (when system was at 0bar).
What should the pressure be on a vokera?
The pressure increased by 0.3 bar and stayed at 1.8bar during the time it was running. turned heating off and popped out, upon return pressure had resettled at just below 1.5 bar. normally the pressure would have completely or very nearly totally dropped down to 0.5 – 0 bar by now, so fingers crossed all is good. Heat likes this.
How can you tell if your boiler is losing pressure?
The speed at which your boiler loses pressure determines how bad the new leak is. So, if your boiler is losing pressure slowly (i.e. you can’t visibly see the dial going down, but pressure goes down overnight), the leak is small. If you can visibly see the pressure gauge going down, your boiler is losing pressure quickly, and the leak is big.
Why is my vokera expansion vessel losing pressure?
As no water escaping when valve pressed and system pressure rising when you pump air into vessel, then the vessel might be okay. Just be careful to check the Schrader valve isn’t leaking air once air pressure done. (I damp my finger and press it partly over uncapped valve to see if any bubbles happen)

Why is the water pressure on my vokera going up?
The water pressure just increases due to the expansion vessel air side pushing the water side. If you try the valve on the expansion vessel and find no air in it despite having pumped air into it earlier, then the vessel is faulty.
Where does hot water go in a vokera boiler?
Vokera combi boilers direct hot water to the radiators or hot water taps, depending whether you want heating or hot water, through a diverter valve which directs the water in the appropriate direction. The older a boiler gets, the more prone the diverter valve becomes to getting stuck in the wrong position.
Why is my boiler losing pressure but no leak?
Is Your Boiler Losing Pressure But No Leak? Causes of a Pressure Loss in Your Boiler #1 – Pressure Relief Valve on the Boiler is Faulty #2 – Auto Air Vent Leak in Heating System #3 – Leaking Radiators, Towel Rails and Radiator Valves are Leaking #4 – Radiators Are Full of Air #5 – Dodgy Expansion Vessel
