I did it eventually. I might add I am a 52 yr old woman living alone and feeling very proud of myself.
For anyone else who has the same model...ensure machine is unplugged. Remove retaining clip around seal on door, slip seal from door.
Take off top, there are 2 screws on back for this. Remove soap drawer, unscrew 4 screws. Loosen screw holding control knob and slip knob off. Unscrew one screw keeping panel on. Remove panel, taking care with wires.
Remove front panel by unscrewing 3 screws on top and bottom, swinging panel carefully to the right.
Seal on drum will be visible now and retaining ring easily reached. Unscrew screw and slip ring off. Ease rubber gasket from drum.
Fit new seal over drum. I simply reversed all instructions and it works a treat. Saved me a fortune Phil !! :)
