Diplomat fan oven APL3301 door problems

Hello,

I’ve searched the threads and don’t think I can find this specific problem.
Somehow, don’t ask, I’ve managed to remove the door off my diplomat fan oven APL3301.

I can’t get it back on correctly. I’ve managed to get it partially on, but it doesn’t sit correctly.
Any ideas about the correct procedure for re-attaching the door.
I’ve check the manual and there is no mention of removing the door or re-attaching.

Thanks in advance
Ronnie
