What is the problem you are having with the washer?
Ok what you need to do is remove the door seal from the front of the washer so remove the outer clamp and then you can remove the seal from the front panel.
Now you need to attach the door seal to the tank. Look in the door seal and in the middle part you will the small draining holes. These need to be at the bottom in the 6 oclock position.
Then lip the door seal onto the drum and feed it all the way round.
Once you have the seal on then you need strech the bigger clamp onto the door seal.
Then you can reattach the seal to the front cabinet and refit the clamp.
No ive found a clip on Youtube on how to fit the seal. Now they remove the control panel to get better access so that you to you if you do it as i dont remove that.

Have a look at that and the above what i have said will make sense for you.
Just wondering how you got on with the washer as the question is still open?
Did you manage to get the door seal on?
