Hi, When I operate my AEG 57700, water accumulates above the door. I took the dryer apart and found that the plastic white wheel is broken on my machine. That is, the white plastic shaft does not connect to the spinning metal shaft. What is that white plastic wheel called and what is it's purpose? Should it be connected to the metal shaft? Could the fact that it is broken be causing the condensation, or am I more realistically looking at a pump replacement? Thanks
