Does anyone recall if either of the consumer testing organizations tested the Preway Gas dishsmasher? I know that it used a spark plug to ignite the gas. Heating the wash water to 160F before the washing begins sounds not so good for proteins and starches. Seems like a prewash or a wash that is heated to 160F would be better, but I guess the combustion tube had to be covered with water during the heating, maybe. Maybe it could have washed for a few minutes and stopped to heat the water to 160F.
