We have one of these which is used to provide hot water for washing etc. It is old (I think that Noah may have thrown it out), but has worked well until now. It currently thinks that the water is flowing when its turned on; sadly the taps are off! This is dangerous as the water just gets hotter and hotter. I guess that somewhere in it is a pressure/flow switch which has stuck open. My only thought on how to deal with this is to pump something like diluted vinegar into it so as to descale it. We are at Chatham and so have quite a build up of scale in the kettle. I have tried Vaillant but all I got was a 50p a minute help line, which after 8 mins had not been answered.
Any thoughts on the best way forward?
