TANKS, BUDDY
So these higher end KM models allowed you to use only one drain hose when in the off position like the GE Save/Return switch. Only familiar with the MOL's which simply featured the Suds setting on the main dial--no cool extra switches to play with--Darn!
Having the OFF button would save on the clangs of the Suds valve when not in use, but that signature clang is all part of the magic. Wonder if Roberto will use the Suds-Return if for nothing else than the sheer fun of it.
Now, how 'bout that Visimatic off/on switch. ;'DDD
