POS dishwasher and Non-POS dishwasher
Well the el cheapo builders' model WP dws are no dream with those big tubes in the middle of each rack so that it's almost impossible to position a mixing or serving bowl or a large pan in the rack and no wash arm under the top rack so if you do put something like a saucepan or bowl in the lower rack, you can't put anything above it in the top rack.
WP is discontinuing production of its only convertible portable, the one with the standard tub and replacing it with the Maytag tall tub convertible portable. The Maytag is not a very deluxe machine. I have no idea of how well it will perform, but I would hope that it would not have to sit in front of the sink and monopolize the faucet for some of the long cycle times I have seen for the new dishwashers.
