No water pressure at boiler (Fault F22 Vailant EcoTec 618)
Discussion
Hi chaps,
Issue at work with no hot water. This is since the storm of last night. Apparently the staff who arrived this morning stated that the computers showed evidence of a power cut).
The boiler (Vailant Ecotec plus 618) is registering no pressure with the associated fault code F22.
Done a bit of googling where it suggests turning on the water pressure to refill. Unfortunately the boiler does not have the grey levers as per this video: https://www.youtube.com/watch?v=6ZwPQFF6Nvk
It does seem to have a filling loop (?) (mentioned in other links I've found).
The set up is as below:
Turning the blue level makes no difference (no rush of water) and neither does the 'hex' bolt on the opposing side.
The 'valves' under the boiler are both in the 'on' position (and always have been).
Any ideas? TIA

I would pop the front off and check the pressure valve on the inside, just to check it's not a fault with the actual sensor and the pressure is actually correct.
caveat: I would do this on my home boiler and accept the risks but strictly it's part of the internal workings of the boiler and should only be done by someone Gas Safe, may be of concern in a commercial environment.

The fill valves shouldn't always be "open".
Have you tried turning them? Turn one 90deg. Then turn the other slowly and you should hear the boiler fill. There'll be a gauge under the flip down front cover...watch this and don't overfill it. Once done, turn the taps off again.
If you don't hear any water flow I guess there could be a problem with your supply. Are you getting cold water?

Thanks to those who replied.
We are getting cold water.
It's certainly an unusual situation and wonder if the storm has tripped something we're missing.
Regardless, plumber is coming on Monday so I'll try and observe what the solution is.
Thanks again chaps.

Yes I tried turning them with no improvement in matters. I found them in this 'open' setting so I can only assume they've always been like this.Have you tried turning them? Turn one 90deg.

IANAP but you have to open both valves.
In the pic the blue one is open but the iso valve is closed - you open it by turning a screwdriver so the slot is lengthways to the pipe (ie a 1/4 turn)
Tried that also. Again, didn't seem to do anything.In the pic the blue one is open but the iso valve is closed - you open it by turning a screwdriver so the slot is lengthways to the pipe (ie a 1/4 turn)

Is there a mechanical pressure gauge?
Yes at the front. Was reading zero.essayer said:
If it's a 618 plus it will be inside the front case.
Both filling valves shouldn't be left on, it'll be over pressure if it is and dripping out the overflow
Interesting, that's how I found it so I have to assume it has been like that since the last time it was attended to (unless someone was fiddling it before I had a look at it).Both filling valves shouldn't be left on, it'll be over pressure if it is and dripping out the overflow
To update the thread, the plumber came out on Monday.
Stated that the blue 'valve cover' was broken and fitted a new one. I could tell it was broken and opened the valve 'manually' with a screw driver (though that didn't seem to fix things). I suppose he has the magic touch (or actually knows what he's doing!).
Seems to work fine now. The inlet/outlet valves under the boiler are still in the on position.
