hi - you need to remove both side panels by removing a ciouple of screws iether side and manipulating the panel out. Then you can release the springs holing the hinges in plcae and withdraw them with the door friom the frnt.
The plastic bits are a litle fiddly but just copy the old ones. IUse the new hinges and plastics to give a more secure door. The plastics once assembled slide intpo the door front and stay in place using a screw. Then you are ready to put it all back together in reverse order
Good Luck
