A50
I have attached a crude diagram of the drain system. The drain setup is nearly identical to the Hoovers that you are familiar with. The machine's 1 pump is belt driven from the spinner motor and is attached to a spring loaded arm that acts as a belt tensioner much like a Maytag automatic. There is a diverter valve with front panel control used to select which one to drain.
I assume that the motor that is used is simply not powerful until it gets up to speed, it doesn't handle strain at startup very well and takes a bit to get up to speed. This is my guess for the slip-belt and spring-arm pump housing.
The dual impellers WOULD be better if the tub were larger, but as it stands the tub is just too small. The wash tub is deep but small diameter, if you overload the machine which isn't hard, you get similar tangles as a Hoover. The reversing I think mainly allows for more movement of the clothes in that small space. If the clothes stop moving in one direction, which they sometimes do, it reverses and sucks them back down the other direction. The machine is only 24" wide as the Hoover is 29" and the Servis based units are 32" wide so it's tiny. It doesn't handle large items well like plus size khakis and only one pair of jeans per wash cycle.
This machine is just a different breed in many respects than most European units, I'd say the motors used being the biggest difference, but size and characteristics as well. The lack of spin rinse also deals it a blow on that market. If it were introduced on the market there it would have failed horribly I believe. For the US market, in which this was a much more out of the way niche market it survived on the Maytag name and the size. That's not saying it was a hot seller, but sold enough for Maytag to make them from 1970 to 1982.
I enjoy the A50, even for it's short comings. If you use the matching DE50 like I do, the wash and dry times (roughly 60 minutes per basket) sync up with each other nicely. The pump drains the wash water out in about a minute flat and so it's not that bad for me, I also use conditioner in the rinse so with a deep rinse, spotting is less likely. I think portable was the key and Maytag won that one, it's to my knowledge the smallest domestic twintub made. It's a solid built machine that's long lasting. The size to me makes the slight compromises more reasonable.
