My Amana front load only has a couple of inches in the bottom during the wash. More water doesn't mean cleaner clothes. In the old top loaders the tub had lots of water, but it was just a fluid medium to allow the clothes to roll over so they could all have an opportunity to be rubbed by the fins and each other. Clothes need three things to be washed. A chemical action-detergent,A thermal action- warm or hot water,and a mechanical action- in this case the tumbling action of the drum which allows the clothes to rub each other. You just need enough water to dissolve the detergent and make a sloppy soapy slurry for the clothes.
