Vailliant EcoTec Pro 28 error message

[Chuckles1066]

Hello,

We could only get luke warm water out of the taps this morning (central heating is fine), the LCD was flashing "0,7 bar", I assume this is related?

What does the error indicate?

Many thanks for reading. (I've looked in the manual but it just gives a list of codes beginning with F).

Water pressure in system needs topping up, this is done via a filling loop (internal or external). MI's will explain how.

If pressure drops again soon after, then further investigations will be required.

So it's not mains pressure related?

And can it be sporadic? Only my wife drew some water lunchtime and the temperature was fine and now the "0,7 bar" flashing message has gone?

No, not mains related.

System pressure should be @1.4bar when cold... Yours is half that.
