ah ha! you don't remove the plastic cover, but "simply" remove the rest of it. I've just pulled an elastic band out of the drain pump and it's taken most of today.
Now then,
Inside
- unscrew all parts of the salt store
- take off the spinning arm
- take off the pipe that takes water to the top spinning arm
- take out the filters
- unscrew the circular bit of plastic that surrounds the filters
- take out the bit of grey plastic above the water entry
Outside
- take off the top (clips at the back)
- take off the side panels and panel beneath the door
- put the dishwasher on it's door and unclip the springs for the door, put the DW upright and unclip the door
- take off the door panel
- disconnect the wires on the door (making a note of where they go for reassembley later)
- remove the door (note rubber strip and the pivot points)
- take out screws on the sides so that you can lift the actual dishwasher away from the fittings beneath.
- voilla! all the workings of the dishwasher are revealed
- hope this helps
