Those were wonderful machines
Bauknecht was always a strong player in the German market - not the same exalted quality (and price) and Miele, but always far easier to use and with more useful features than the Bosch, Siemens, Constructa group.
In quality, they were somewhere between AEG and Siemens. Which is still 1000X better than anything built nowadays.
I've taken a lot of shit for saying it, but it's true none the less: Whirlpool killed this wonderful brand's reputation. The Bauknecht of today is, sadly, nothing at all like what you have there.
By the by, replacement parts for many components can be sourced at regular German parts houses or using industry standard components - Bauknecht used a lot of AEG and Siemens parts, thank goodness.
