Tilted tub front load washers
The big American style machines have some tilt often times but less than they used to less than the original duets and the Maytag Neptune's because they tangled so badly.
In reality, a front load washer should not have any tilt to it. No combo ever had a tilted tub And as pointed out, I don't think any 24 inch machines have a tilted tub where you need maximum capacity and you don't want tangling you don't want tilted tub.
I don't think I've ever seen a true commercial front load washer with a tilted tub ever either. It just doesn't make any sense from a performance standpoint.
No clothes dryer has ever been built with a tilted tub because the performance would be terrible. Can you imagine trying to dry things of everything is balling up in the back?
