Candy CDC266 how to get inside?

Hi there!

We have a Candy CDC266 condenser tumble dryer that when running is really noisy but only going in a certain direction. I’ve been reading the forums and want to have a look inside and see if I can grease a few things, tension pulleys and possibly replace if needed. However I have just spent the best part of 2 hours trying to get to them with no luck at all.
I have taken the 3 screws off the back of the lid and that slid off ok but then I’m lost. All that’s there is the great big drum with the belt round it and the front panel. I’ve taken out pretty much every screw I can see from front, back and bottom but still can’t seem to see how the panels come off??
Does anyone know how to disassemble one of these please? It would be much appreciated!
