No, only in German.
Yes, the drain works fine.

I can confirm that, after contacting Bosch support, this is their reply. I think it's a real shame that this isn't indicated on the article!

The model that you have purchased WQB245B40/03 is a model for German production. This means that you cannot change the language in the system.

However, we can suggest that you order a legend (this is a sticker that you can apply around the programme selector to have it in French).
The right-hand side of your screen will unfortunately always be in German.

If you wish to order the legend, the article number is (10029052)
You can order it either via our online site or via our spare parts service.

We hope we have answered your request.

Best regards
Sincerely
