Replace it.

Welcome aboard, sorry to disappoint but I have never seen any microwave display with a variable backlight.

The seal on the microwave door glass is compromised and allowing moisture and perhaps the microwaves, to enter between the windows inner and outer.
There is a great potential for leakage here.
I would not continue to operate this oven until I have it fixed.

This can be due to wrong choice or fault in the power supply ,main board or the magnetron.
You should try with a preset selection and if the microwave works then the fault relates to correcting the power to time settings.
Check out with microwave cooking tips.

I would suspect a bad door switch or door switch mount, or possibly a bad electrolytic capacitor on the control circuit board.

Beyond that, I could only speculate, since I don't have experience or information on AEG products.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Then you can detach the keypad connector (as per attached photo) then remove the control panel screws.

Be careful not to crack the glass display when handling it, or it's a goner.

Then you can use a soft cloth (not a paper towel) and a mild cleaner (not ammonia-based) to clean the front surface of the VFD display glass and the rear side of the clear bezel (display window) that's attached to the keypad.

Direct spraying of cleaners on the keypad and steam from the cooktop can damage the controls.

I always recommend that you spray non-ammonia cleaner on a soft cloth (not a paper towel which can scratch) and gently wipe the keypad.

The motor opening some air valve is probably stuck. See "AEG “micromat_combi 635” halts with error E14. What to do?" at http://appliancewiz.com/questions/47/aeg-micromatcombi-635-halts-with-error-e14-what-to-do for some images and instructions.

The first thing to try is a "hard reset". Unplug it from the power line for a few minutes, plug it back in, set the clock, then try again.

Otherwise, your best bet is to contact AEG customer service here:
http://www.aeg-electrolux.co.uk/node137.asp

I'd bet that customer service will not know the meaning of the code (if it's not in your owner's manual) and they will steer you to a service center.

The service center will probably not tell you what the code means, preferring instead to repair it for you.

Good luck.
