The problem I have with my tumble dryer it shuts down with the tank full indicator on. When you open the door to remove the tank, the tank is empty. I removed the back cover to reveal a water collection chamber which was full, I decanted this water away. Put the mains back on and the machine started. The problem appears to be when the tank pushed in it does not unseat the tank valve to allow the water from the collection chamber to flow into the tank. Is there a drswing showing how the all assembles along with a part number for the small "O" ring for the tank valve as one I have is stretched and does not seat properly in the retaining groove slotted in the tank valve.
