My sister and brother-in-law had one of those BOL WPs--in a house on a golf course that was advertised as "luxury", mind you. It did a fine job if you didn't ask too much of it. We joked about it's Hit-or-Miss (TM) wash action and SewerGrate (TM) filtration. Hers was the "top" of the bottom-of-the-line, so it had the thrid level wash, which was a 1 quart-sized cylinder mounted to the middle of the top rack that redirected the center jet from the tower to splash around at the tops of things in the upper rack (that were shorter than it). Because of that, and for other strange design reasons, it seemed to hold 3/4 of what most machines would hold. She always ran it on Pots/Pans amd got by.
Yay for Builder's Best
