AEG 8000 tumble dryer - service/diagnostic mode

[gsf600y]

Anyone know how to get an AEG 8000 TR819P4B heat pump tumble dryer into service/diagnostic mode?

If it turn on, and press START+SILENT, it shows me an error code (E32), but I believe there is a diagnostic mode for testing the various functions out.

I've tried pressing and hold those same buttons and other during turn on, after turn on, etc, etc, but can't find the magic combination.

Thanks

the adverts are a bit of a pain but it gets there eventually.

Thanks for that link. I'd already found that example, and quite a few others, but try as I might, no joy. My buttons are slightly different to the video, but I've tried:
- all sorts of combinations of START+another button (including delay start in the example video)
- all sorts of timings of pressing those two buttons
- releasing ON/OFF and not releasing ON/OFF

Now, turning on normally, then holding START+SILENT does show me a single error code, but I gather there is a service mode that lets you scroll through individual functions and test them, and that's what I'm after.
