For a couple of months now the CH side of the boiler has been leaking water. It would leak for a couple of days and stop. Very intermittent, but very annoying when we get water dripping everywhere (so the system would depressure quite significantly). I have isolated the behaviour to a valve on top of the boiler which the installation book tells me is the 'Automatic Air Vent'. I do not know why it is doing this. I have tried to find someone who can investigate and repair this make of boiler though without any success. I live in Reading, Berkshire , and if anyone has any suggestions I would be very grateful!!!
 
Its a long time since I worked on one of these but I am pretty sure the AAV is outside the boiler case , until you have time to get it changed you can turn it off , it will have a small plastic/brass cap , simply turn this off , only goes a turn or so .
