right on the money!
Sudsmaster and Appnut, you are both right on the money with the old HOKA dishwashers. There was never a heating element in the tank until the KDS15 series and only on the Superbas as they had the 180 Degree Sani Cycle. The UM based(Hobart Commercial Undercounter) 10-14's had no supplemental heater at all. Some of the 16 series Imperials had a lower wattage element which boosted the water temperatures, but no Sani Cycle with the Superbas, coming with the 1400 watt element.
I will stand to be corrected, but I beleieve the 17 series had the water purge at the beginning of the cycle but not in between the cycle segments. Some say the 18 does too, but there is a longer circulation of the water than in the purges we heve gotten used to. I know for sure the 21's had them between all phases and I used to remove the flow washer in the valve on ours so it was like getting a full rinse in between each segment as well as a guarantee of a fill water charge as well. Talk about really cleaning!
Hobart continued this design philosophy even up to the 18 series with the Custom models missing the element altogether. True, we were still setting our water heaters up higher then so I guess they figured it wasnt always needed.
Personally, I have never bought into the notion of setting my water heater at 120 degrees since it would require the dishwasher to run longer to heat its own water and when a person showers, they would draw more of the heated water than if they had to mix cold water to temper the hotter water. I never did any scientific analysis and I am sure engineers have done so, but it seems more of us were able to shower consecutively when the tank was set higher, thus the less hot water more cold water scenario.
Once Hobart went to the 19 and up series, almost all of their machines had elements to heat the water in one form or another.
What was so interesting was that all the same European models of the american units, whether domestic or commercial were fitted with water heaters and in the case of the commercial units, could be optioned to have built in 180 Degree water boosters under the machines like nearly all the commercial units today. Ocne again showing that the European designs were always light years ahead of our machines.
