Other way around...
...I think Bosch/Siemens bought in the Balay machines and rebadged them as their basic line. The Bosch machines had model numbers starting with WFB. I loved the slightly later version I had for a while - basic but flexible programming and generally very sturdy in construction.
The wash water level looks higher than it was on later machines, where it sat well below the rim of the drum.
I take it the IRIS system was some kind of water/electricity saving system, in which case the BSH rebadges had it but by another name...something like the "2D Aquaspa" system.
