Top removal on a CredaTVR2 dryer?

The belt is broken on this unit, have partly removed front but its obviously locked in on the top with the control fascia panel etc. How can I remove it ? I know the top has to be removed to gain access from above. But I don't want to break off plastic fixings which is so easy to do if things are forced. Like the previous emailler I have also found the inside packed with fluff even around the heater elements, bit worrying!
