On the rubber seal at the door, you will find a wire going round the entire circumference of the seal, which holds the seal to the body. Unclip this wire where the two ends meet and the wire will come away from the seal. Unplug the machine and remove the lid. On the inside front area, above the washer door, you will see a strip of metal which is holding the rubber seal to the inside of the drum, (a bit like a large 'Jubilee clip'). Loosen the bolt/screw at the point that the two ends meet, until loose enough for the retaining clamp to fall free and free up the seal.
As you pull the seal away from the drum and the body via the front washer door, NOTE HOW THE SEAL ATTACHES TO THE DRUM AND DOOR LIP, FOR REFITTING.
Refit the new one as above, in reverse.
