Leaking Sump on Whirlpool ADG 7960

Hi there
I previously asked for help on the flashing lights on my Whirlppol ADG7960.
Have eventually managed to decipher how to get at the tray at the bottom of the machine and lo and behold as predicted it was full of water!!!
Managed to dry the machine out enough to get it going and water is pouring out of what looks like the sump thing – it’s directly underneath where the filters fit on the inside of the machine. When I had a look inside the machine where the filters fit, at the 6o’clock position there is a piece of the sump assembly which is moveable and looks out of position to me!! Is there anywhere I can get a diagram from that will help me make a decision as to whether this bit of the machine is faulty or whether I’m barking up the wrong tree.
Thanks ever so much for your help.
