Combination oven (Waingroves DE5)

Panasonic combination oven. (They cost £560 new) Microwave, convection, grille, steam. The front layer of the multi layer front door has broken away because the tiny plastic bosses the retaining screws screwed into have broken away. I like using it so I bought a new one but since learned that the door is easy to repair if you are DIY minded and look it up on you tube.
