how do you take the lid off an AEG 1261 sensortronic?

undo 2 screws at the back as you have already done.with the flat of your hand hit the front edge of the top BACKWARDS then lift off.needs a good firm hit don't be frightened.
its easy to tell if the belt has come off.if it has spin the drum and it will spin freely for a long while,if the belt is connected it will stop quickly.Lay machine on it's BACK ONLY and you will see the motor and the belt from underneath.Whilst your there remove the motor brushes and check that the carbon bit is 10mm or longer otherwise they are worn out and need replacing as this will stop the motor working
