I have had my vaillant for 5 years. It was serviced after first year and again this year .
For the past month i have had to top pressure up at least once a week. This last week i have done it daily.
After i had it serviced last week, the engineer said i must have a leak beneath ground level.
After he left i didnt need to top the pressure up for aporox 4 days.
Since then its been daily again.
There is no evidence of leakage anywhere in property.
I have topped the expansion vessal up to 0.9 bar.
Pressure still dropping.
Now when i top pressure up the reading increases from 0.3 bar to 1.2 bar in approx 5 seconds.
I am wondering if this problem is sensor related ??
Can anyone please help ?
