The side panels don't come off.
Open the door and take off the seal retaining ring, you'll need to dig this out of the seal.
Peel the seal off the front panel.
Take the screws out of the door lock.
Take out the dispenser and remove the screws revealed.
Take the panel under the door off.
Take the screws revealed out.
Push the front panel down and lift it off.
If it's still held in place you'll need to take the facia panel off to get to a hidden screw.
Reassembly is the reverse of the strip down.
To refit the door lock, reach in through the port hole and fit into place, screw it in then fit the seal.
Hope this helps
Let me know how it goes.
