You've got yourself an early Bosch washer
From about same period (middle to late 1990's) when Asko, Miele, Bosch and Creda were making inroads into the American laundry market with their "compact" washers and dryers.
Like early Asko units that Bosch washer plugged into the matching dryer IIRC. You then plugged dryer into outlet.... However there is nothing wrong with just plugging washer itself into proper outlet (208v-240v 60hz 15amp)
Unlike later Miele washers (19xx onwards series), these early Bosch, Asko and Creda washers and dryers were all straight 208v-240v machines, no 120v required.
Like Miele washers of same period unit *must* be connected to hot and cold water taps, even if used as cold fill only. You'll need a "Y" connector to split water from a single tap to both hoses if you're going with cold fill.
Keep in mind while the washer is designed to work with hot and cold water, it can run as cold fill, cycle times will be longer as it will take more time to heat the water.
There should be a little wrench (came with kit in new washer) used for tightening nuts and leveling legs. It should be stored behind toe kick panel (use screws to remove).
Big thing about these Bosch washers was their strict warning against using chlorine bleach. Period, full stop, just don't do it. IIRC from old discussions about Bosch washers use of chlorine bleach voided the warranty.
All and all this little Bosch is a pretty sophisticated bit of kit.
Bosch called their wash system of the time "Sensortronic Plus" and it has features like suds sensing, unbalanced load detection, delayed start, end of cycle signal... Machine constantly monitors cycle and will add or subtract time based upon load size, soil levels, any OOB issues and more.

Bosch uses a brush motor in this machine and sooner or later they (the brushes) will need replacing.
