Great Dishwasher
The tub is porclean over steel and the inner door panel is molded plastic, an excellent combination.
The center tower is not much of a problem, unlike the the center towers in GE, MTRR, some WCI and several other DWs it is very slim and does not move so you can even have items wedged against it and not interfere with its operation. This upper rack wash system will out wash any top rack in any DW ever, even tall glasses in the corners of the top rack get clean, unlike other overall excellent DWs like early 80s GEs, MTRR, and Kitchen DWs.
I hate to use the term, but if I was close this DW would be gone, but I already have one, John L.
