The machine is the Hobart design, pump and all, with an Emerson motor. 1/2 HP "gold seal" unit. It's a good dishwasher, for sure, but it has only one rinse, which just isn't always enough. The wash phases of the cycles are very short, maximum of 7 minutes, even in Soak&Scrub. The 23 series introduced the longer main wash...about 20 minutes, which the machine very much needs. Just doesn't do a great job on pots and pans. Does a good job on dishes, glasses and utensils, though.
It's a good dishwasher, and it makes beautiful sounds, but my LG dishwasher cleans circles around it.
But you buy this machine for the nostalgia, the history, the sheer thrill of it all...and if that's what you're looking for, it will definitely give you that!!
