Also it's worth remembering WWII basically completely stopped ALL european consumer product innovation for about 20 years.
During the late 1940s and 1950s, Europe was effectively flat broke and rebuilding. So, many households wouldn't have even been able to afford a washing machine.
Hence, it's not supprising that the first front loaders and automatics arrived in the 1950s rather than the 1930s and 40s.
Also, once WWII kicked off almost ALL manufacturing capacity was converted from producing consumer products to producing weapons, military communications systems, radar, etc etc
So, in general, many of the companies that would have been innovating were tied up making military products.
