On the lip of the door seal, on the outside of the machine you should be able to see a thin wire running the full circumference of the seal.
At one point the two ends of the wire retainer are held in place by a clip. This clip is easily released and the ring of wire will come away from the seal.
TURN OFF THE POWER AND UNPLUG before you take off the top of the machine. Once the lid is off, look down the front where you will see the rubber seal and where it meets and fits on the drum.
You will note another retaining wire, this time held in place by a sturdy nut or screw, (which works like a "jubilee clip"). Use either a screwdriver, or small socket, (depending on retainer connection), and turn the head anti-clockwise. This will loosen the wire and free the seal for removal by simply pulling it slowly off its position, out from the door area.
NOTE: please pay careful attention to the way the seal is fitted to the door area and drum, e.g. the way the seal connects to the lip on the outer face, etc. as you pull it away, so as you can fit the new one in the same manner and not get confused.
Once you have taken care to note the proper way that the seal connects, just reverse the above procedure.
Oh! DON'T overtighten the inner retaining wire by turning the nut/screw too much in case you cut into the new seal. If it took three or four turns of the screw/bolt to loosen, just use same amount of turns when reassembling.
Good Luck.
