I have had my worcester greenstar 30cdi boiler for just over a year now.
Lately we have been hearing a dull juddering,vibrating noise which seems to be coming from the top of the boiler although it is hard to tell as the noise only lasts for around 5 seconds at a time.
The noise happens at night mostly.
I dont know if this is related but there has been water leeking from the pipes supplying the mixer shower.It looks like its leeking from the elbow joints.
Aslo occasinally a small amout of water from the shower head emptys on to the tray.strange?
any help would be much appreciated
