A long magnetic screwdriver is very helpful for this step, and almost essential for reassembly.

Remove a screw and toothed lock washer from the rear left of the metal plate.

Remove a screw from the rear right of the metal plate.

Remove a screw from the front right of the metal plate.

Reassembly is easier if you remove the right hand side panel. Release 2 clips along the bottom edge with a spudger then lift.
