Hi, I have one of these too. The W723 was never sold in English speaking countries.
The german manual can be downloaded from: http://www.miele.de/de/haushalt/service/manuals.aspx
The W820 is a similar machine, it's english manual can be downloaded from: http://www.miele.co.uk/Customer/OperatingInstructions.aspx
Hope this helps, Geoff
