Vaillant Ecotec Pro 30

[Ian245]

The boiler is displaying the error code F2.2, which is low pressure, currently at 0.4 bar. Last week when this happened I managed to increase the pressure to 1.5 bar by using the two taps located under the boiler.

Today when I tried to increase the pressure nothing happens when I turn the two taps. Can anyone throw some light on the problem. I have checked the house and there are no obvious signs of a leak. We are currently without hot water and central heating.

Many thanks

Ian

The plastic taps are notorious for breaking, unscrew the plastic handle and turn the valve using a small spanner.

Why are you losing pressure needing you to fill up a week later.
Keep eye on pressure gauge when boiler is up making sure it’s not going up to 3 bar
