I bought new valves as the chap in the shop told me that was the problem, it wasn't!! How do i check if the pressure chamber is working properly?

On the machine there is a diaphram valve which controls the fill hight of the water, this could be blocked, in hard water areas this often happens and causes the machine to continue to fill.

Unblock the valve either by dissconecting the small black/clear tube clean chamber and lightly blow up the tube, you should be able to hear two small clicks. Once you hear the two small clicks you know that the diaphram is working.

So the chamber should be cleaned out of limescale and rinsed re-fit and all should be well.
