Oké miele during war-time
produced untill halfway 1940'ties the 'normal' products like washer, mangles, but also stairs and even bikes... Then they where forced to change to war-time products like small stoves to steam food for the animals,manly potatoes (untill 1941), and handchariots for the military and civilmarket, but also pieces for planes (due to their know-how in wood and metalconstructions).
Besides all that, what is the shortest program on your miele dishwasher? Mine is Normal 50°C = 70 min but everything is spotless!
