How to bleed a vokera syntesi combination boiler

I have identified the filling inlet valve and know I have to turn it 180 degrees to do the bleed process. However, when i do this, nothing happens. As it is so long since I have done this, I have forgotten the process. From vague memory, I thought I had to turn something else as well. Also, does the boiler have to be off or on for the bleed process to take place. The boiler is only a year old and is due for its first service.  My pressure is and half, below 1. I am not seeing any error messages coming up but I think the water is not as hot as it should be for the settings on the boiler which alerted me to the problem in the first place. Being a Saturday, the help line for this company are closed of course!  many thanks! PC

I think you mean your boiler needs pressurising firstly connect hose hand tight open the non return valve normally teed into a 22mm pipe then flick the valve lever on the cold supply quick little bursts till you reach your required pressure best of luck

Why the hot water temperature couldn't reach the set temperature (130 degree) in Amtrol WHS80Z indirect water heater?


I have a couple of thoughts. You may have air in the boiler water circuit at the loop that feeds the tank. You'll have to find the vent in the loop to get it out. Second, the automatic valve that opens for hot water may not be opening fully. Have you felt both the boiler water lines that go in and out of the tank? If the water going in is hot and the line out is very cold you have very little boiler water going through the loop. Make sure the isolation valves on the loop are open. Is your boiler full of water? If the boiler loop lines are hot going in and coming out, the tank is full of rust or debris and no water can get to the fins on the internal tubing to pick up heat. If that's the case there is no repair and its time to get a new tank. Hope this helps good luck.

Vokera aav leaking


Robert, i'm sorry to say but the AAV's are machined parts and the seal should not have been broken by removing the cap. The floats are set perfectly and you would have been easier replacing the whole vent. You could have isolated all the pipes under the boiler and just drained the boiler down by releasing any pressure by the pressure release valve. You may need to buy another AAV and start again.

How do i refill ny worcester junior 24i combi boiler? as i cannot get the pilot light to light


Two types dependent on age
Early - in the mains water inlet pipe there should be a service valve/tap which when turned on will refill [it is close to or part of the fill loop - a metal braided flexible pipe
Later - underneath there is a hole for a plastic tap [supplied with boiler] to be inserted [usually just right of center] Insert and turn 90 degrees then close to it another small knob or 2nd tap which when turned [same action as a basin tap] will refill. If the first tap is not inserted properly water will drip out past its seals
For both Refill to about 1.5 - 2 bar and turn off
For the later as above but also remove the 1st tap

Low pressure on recently serviced Vokera 14/48se.


Identify the cold feed to the boiler, then look for a tap/service valve which when turned lets water into the boiler via a fill loop to pressurise it. 1-1.5 bar is ok

I have a VOKERA 24 boiler the Linea range which was working fine until i notes the pressure was a little under 1.5 Barr. I topped it up the pressure with the filling loop every thing was fine. The next day...


Water logged expansion tank ( ruptured diaphram in tank) or wrong size tank. This caused the excessive pressure in the system causing the relief valve to open. Also, air in the system causing flow to stop, Both conditions will cause boiler go out on safety.
