    Vaillant EcoTec Pro 28: F.22 warning (low pressure), but no filling loop

    Yeah, I've bled 3 of my radiators for a bit, will turn the boiler back on in an hour and then bleed some more if it's still too high, thanks again :)

    Vaillant EcoTec Pro 28: F.22 warning (low pressure), but no filling loop

    Amazing, it works now, thank you!!! It did shoot up to 3.1 bar within 15 seconds, so I will turn the boiler off for a bit to lower the pressure.

    Vaillant EcoTec Pro 28: F.22 warning (low pressure), but no filling loop

    That was the trick, thanks :) Found this hidden behind some loo roll :P Should I turn both taps?

    Vaillant EcoTec Pro 28: F.22 warning (low pressure), but no filling loop

    Popped over to hers, it's a Vaillant boiler as well... but she has the filling loop right underneath :( Would I be able to borrow her filling loop and valves and use them on my boiler if all else fails? I had a rummage around with my hand as I couldn't see that well; just felt three pipes...

    Vaillant EcoTec Pro 28: F.22 warning (low pressure), but no filling loop

    Top: Middle (this is the top shelf of the cupboard below): Bottom (bottom shelf of cupboard below): Left of bottom: I only moved in a year ago, but I will speak with a neighbour who said her boiler was installed around the same time as mine by the same people.

    Vaillant EcoTec Pro 28: F.22 warning (low pressure), but no filling loop

    I did look for one in the airing cupboard by the shower, but that is empty save for a switch for an immersion heater which doesn't work :/ Can't see any piping leading out from the bathroom, either.

    Vaillant EcoTec Pro 28: F.22 warning (low pressure), but no filling loop

    Nothing stands out to me here: If I bought an appropriate filling pipe could I attach it to just underneath the boiler?:

    Vaillant EcoTec Pro 28: F.22 warning (low pressure), but no filling loop

    I had a look in the cut out but I can't see anything :/ I tried tor remove the shelf to get a better look but the piping is in the way. I think that goes to the washing machine? Also had a look in the cupboards above the washing machine but no piping there:

    Vaillant EcoTec Pro 28: F.22 warning (low pressure), but no filling loop

    I took this video to give an idea of the layout: It looks like one goes outside, and three look like they may be behind the boards of the cupboards below?

    Vaillant EcoTec Pro 28: F.22 warning (low pressure), but no filling loop

    Thanks, here are photos from the cupboard underneath the boiler: Sorry I am not sure which of these would be the cold water inlet pipe?

    Vaillant EcoTec Pro 28: F.22 warning (low pressure), but no filling loop

    That's all the piping I see to the right :shrug: Cheers, that does make sense, the washing machine is to the left of that blue valve so I think you are right. From what I've seen online I should be looking for at least one valve connected to a braided hose, but I don't see a braided hose anywhere.

    Vaillant EcoTec Pro 28: F.22 warning (low pressure), but no filling loop

    Was away for a week and came home to F.22 error code on my Vaillant EcoTec Pro 28, with a pressure reading of 0.4 bar. I understand that once the pressure is below 0.5 bar it will turn off. Videos I watched recommended turning the valves on the filling loop, but it seems mine doesn't have one? I...
