Yes, the water level was decent with these machines but not extremely high. At that time there were machines that used a higher water level. Actually Bosch was known for not so great rinse results, mainly because there was no spin between rinses. These machine only had a final spin.
I always loved machines with a dispenser on top, they seem to do such a better job at flushing the detergent. I have no idea what kind of drying system these machines had.
IIRC the key plate operated machines came with two keys. The one that was not used was stored in a space just behind the control panel.
Right now I can only think of a commercial Miele machine that also used a key plate system, but there were probably others.
