Open the oven door fully. On the top of each hinge is a locking catch to fix the hinges in the open position and remove the door from your oven.
Lift the locking catch as shown in the direction of the arrow. Grasp the door by the sides and lift upwards to remove it from the appliance. You can now clean the door. To re assemble, offer the door up with the hinges into the slots on each side. Lower the door down and push the locking catches on both sides back to release the hinges. Carefully close the door and ensure it is lined up and shuts perfectly. If it is out of alignment re lock the hinges with the catches, lift the door off and then re fit it again.
