Can you post the model number or product number of the appliance please?
It should be on a label in the door recess.
If posting the product number, prefix it with A so it's not crossed out when posted.
OK Fred,there is a silver strip on the oven upright with the following info on it:
AEG E 1000-2-M PNC 940 316 789 TYP 90 AEB 07 AA S No. 43122725
Hope this helps.
I've uploaded 2 pages from the user manual for you.
They show how to remove the door and take the glass out for cleaning.
Click here for the instructions.
You must download and save them, you can't read them online.
Hope this helps
Let me know how it goes or if you need more help
