Hi, would appreciate some help on this one please 
The above boiler has been installed for 7/8 years now and has been regularly serviced but it has just started playing up.
We noticed that the shower was running luke warm so I checked out the pressure on the boiler and it had dropped to 0.5 bar so filled up the system. Unfortunately, this didn't fix the problem and upon further investigation it was the hot water to all of the taps and not just the shower
The next day it had risen to 3.0, then dropped back down again the following day.
If anyone has any ideas on how to fix this I would appreciate your help.
Thans in advance
