I fixed it myself yeeeeeeeees!!!!!
This problem is solved by removing the top of the appliance, 2 torque screws on back.
Disconnect the black hose from the fitting that drops the water into the back of the tray AND REMOVE the blockage!!!!!!!
It might be fluff or a bit of foil, in my case actually both and I had to unblock it several times before the fault stopped repeating itself!!
But we now have a fully functioning tumble dryer and land fill can breathe a sigh of relief!
Very happy Justin, September 2010
