My Rainbow E series power switch doesn't work (by 2 users)

To get access you need to remove the plastic side cover panels. To remove these, I found the easiest way was to use a small flat screw driver, leverage it under the pastic in the centre at the 'cord end' and lift carefully. There are two lugs at the top and one at the bottom. The plastic panel will 'bow' a little, but with care, it will pop off. The gold looking vents underneath are just a 'facade'. By removing the side plastic panels they will expose three screws either side. Undo these and the top will half of the cleaner will lift off. Good luck!
