I believe this was the series when Hobart began to trouble on this Model with repairs. I think this was the first machine that would dump a portion of the wash water before the Fresh Water Rinse.
The WM series was far more dependable than this as they were like a 15 series KA machine. SS Wash Chamber and the HydroSweep. Mechanical Times and I belive a 4 minute Cycle.
In my 5 years here, I've never seen any WMs for sale on CL or FleaBay.
