Savings ... E'lux is is cutting local brands/badges
Just the same happened on the other side of the Channel : if you check arthurmartin.fr there is E'lux France.
4 the same reason they started double-branding : AEG-Electrolux, Zanussi-Electrolux, REX-Electrolux. I bet by ten yrs we'll have Electrolux only
This also happened in the 90ies when Whirlpool bought Philips whitegoods : first Philips-Whirlpool, then Whirlpool only (and a quality drop-down...)
It is also a parts matter. In the past an AEG dishwasher or washer was totally different from a Zanussi one.
I.E Zannies DW had a big round filter (also similar to US Frigidaires). Now they have the square, "AEG style" filter.
Elux seem to keep in life those brands who have a local strong tradition (i.e. Zanker.de , Zoppas.it , Frigidaire in the US) while other brands disappeared (i.e. here CASTOR and TRIPLEX)
