KitchenAid.
Stay with the 18-20 series machines. The older models are one arm bandits with no wash arm under the upper rack. KDS-18 is the most coveted model for its high use of water per fill, upper constant rinse spinner that washes and rinses the tops of dishes on the upper rack, and a true NSF 180F sanitizing final rinse cycle. Between Whirlpool, Hobart, and Ebay, you can still get most parts for these machines. |

They're Good Machines but you must sacrify space for upper rack results.
They are truly a "Hurricane in a Box" provided they are loaded properly. Loading, Loading and Loading. It's all about racking the dishes properly. Bottom Racks (One armed Wonders or Bandits) Strictly for flat products like plates all sizes and other things like cutting boards. Now, You can put bowled shaped items in the lower rack, but you cannot put something above that item in the upper rack as there will be no wash action because of blockage of spray. They're fun and Noisey with a Snappin' Drain Valve. Hope you find a Great Kitchen. |

KA DWs from the 15 series-the 23 models, any WP from about 1970 on the 1984-1989 Power-Clean models being the best performing. Early 1980s GE machines with the filter and multi-orbit lower wash arm. And many MTs from the 1970s on through about 1989.
The KA Suberba DWs 15-18 with the 180 degree sani-rinse do not qualify for NSF recognition as the dishes never get close to 180 degrees, these KA DWs only heat a gallon or so of water in the sump to approximately 180 degrees and then quickly douse the dishes with the hot water, the hot water drops in temperature instantly. |

As John said these were NOT NSF certified machines. A commercial Dishmachine must provide a guaranteed dish surface temp minimum of 160F for 15 seconds to be certified. This reqires the wash water to be 150F and a constant flow of 180F rinse water for 10 seconds for stationary rack machines. It is 160F wash and 180F rinse for short conveyor machines. For the large multi tank dishmachines temps are 150F wash, 160F power rinse, 180F final rinse. As the KA Superba did not have a target temp for the first rinse there was no way to ensure dish surface temp in the sani rinse. That said I do belive a final rinse heated to 180F would greatly improve final results and reduce bacteria counts drastically. However this would not meet NSF protocal. WK78 |

I haven't been to the Oakland ReStore in over a year, but it shares space with St. Vincent de Paul. The "not" habitat store is apparently part of St. Vincent de Paul. It's across the lot from the ReStore up front near the street. The ReStore was waaay overpriced on appliances when I was last in there. SVDP, on the other hand, was far more reasonable. |

Lol, looks like I at least get an NSF wash out of the 18. With the combination of an incoming water temp of 155F and the 700w heater applied during the wash, I get a final temp of 164F by the time the drain valve kicks in to drain the main wash water. I insulated the entire dishwasher opening as well as the dishwasher itself before installing the 18, so that probably helps keep the temps up. Only complaint is the dishwasher is too quiet now. I miss the testosterone laden Hobart roar :(
When I was running several loads with the 18 in the garage after a seal and impeller replacement, I took temps all over the cabinet with my infrared temper gun during the 180F sani cycle. I was getting 187 on the bottom of the tub, 182.8 on the sides, and 181 on the top of the tub. The water in the sump was at 188F when the thermo was satisfied. I never did quickly open the door and shoot any dishes right when the drain valve kicked in. I'll have to do that next time I use the Sani cycle. |
