Valliant ecoTEC Plus 824 / F22 Error

[FP125]

Hi - first time poster.

This seems a friendly and helpful forum, hoping someone out there can help me out and point me in the right direction.

First of all I am a complete noob at all and I have a feeling I will make a complete pigs ear of something without double checking what I am doing first.

The problem:

Noticed the water was not staying hot for long - checked the boiler and the F22 code was flashing, and the bar reading was flashing between 0.4 / 0.5

I tried bleeding the radiators (seen my Dad do this) did'nt hear any air coming out, just a little trickle of water. I did all the radiators throughout the house.

I checked the boiler itself, the pipes coming out of it / connections. Nothing appeared o be damp or wet (it's in the airing cupboard with linen - they were all dry)

I have seen the YouTube clip below - is this safe to follow? My taps underneath do not turn (presuming they need to be unscrewed??) and not clear which ones you turn - both? Whats the difference between each one? How long for, etc?

Just worried if this is a short term fix - does the problem mean there could be a leak in my radiators somewhere and I am not looking for the root cause - or is just simply the fix as seen below?

Many thanks in advance

yes that is how you do it but stop when it is about 1.5 Bar showing on the digital display, any time you bleed your radiators you will have to do this

You just need to repressurise the boiler!

Bleeding rads is not needed and will lower the pressure even more!

If you cannot do it yourself then get a capable plumber!

Any reason why this happened or just something that you need to do every now and again?

Its normal for systems to need to be topped up a little every few months.

If you decide to bleed rads when its not needed then that reduces the pressure even more!
