This washer looks exactly like the ones I saw in ships. Well, at least this is what I tried to describe in the other thread.
As I previously mentioned, this type of machines do not spin clothes, they just fill with hot or warm water, wash and then gravity drain all liquid, no spin, and proceed to fill with warm or cold water again for the first rinse and repeat for a number of rinses (according to the selected cycle).
You would then transfer dripping wet clothes to an extractor.
Some of the machines were totally automatic, others were partially automatic, others were completely manually controlled.
