how can I stop my Whirlpool Duet (GHW9100LW1) from leaking?

get the doorseal and a pair of clamps.
Undo the fixing (spring, twisted wire or plastic locking band) which attaches the seal to the outside shell and detach doorseal from outer machine shell. Power off, drag machine out onto the floor, remove top cover. Push drum towards the rear of machine and look down to where the doorseal attaches to the drum - you should seen another clamping band. Unscrew or otherwise remove this inner drum clamping band break it if necessary. Pull the doorseal away. Fitting the new seal is a bit like fitting a bicycle tyre on a new rim but on a bigger scale. Start at the bottom and work your way evenly up both sides, using levers if necessary. Lever the seal over the top rim. Ensure it is located correctly and refit both outer and inner clamping devices. If seal should be obstructed by concrete weights the front panel and the concrete weight will have to be removed before seal can be detached.
