Hi
I have a Vokera 12-48 R.S Mynute Central Heating Boiler at the moment which is behaving a bit strangley! When the Heating comes on the pressure rises gradually up to and beyond 3 bars (which is when I panic and turn it off!) However when I switch it off the pressure drops back down again below 1 bar.
I have recently changed a broken fan but other than that nothing has changed since it used to work.
Any help would be much appreciated.
