Welcome to the forum and Eriba ownership.
- To replace the tray would be expensive and not an easy job. Drill a 4mm hole at the end of the crack so it cannot spread, Clean the area thoroughly with methylated spirits, mask of the area and then squirt as much white silicon into the hole so it spreads underneath and fills the hole.
- Unless you can find a direct replacement for the hinges then keep the originals.The timber they are screwed to is poor quality and putting more screw holes in will weaken the surrounding area. I would remove them, clean with a very fine wire wood or scotchbrite and spray with WD40 before replacing them with a dab of pva in the screw holes.
- I would strongly suspect all of the screws on the window fixings are also corroded/tarnished. These can be replaced with 25 x 3.5mm ? stainless from the likes of Toolstation.
- Fridge racks can also be cleaned with scotchbrite. You can replace them but I'm guessing it would not be cheap.
- Your rollers have been damaged by gravel caught in the tyre treads being crushed by the rollers. If they work fine I would leave them. If not, or you are unhappy with them contact a Reich dealer for replacements. It should be a DIY job.
