detergent choice
It seems like everytime I stray from the "good stuff" i.e. Cascade or Electra-sol, performance suffers in my '88 WP. It seems to be more evident on cooked wheat products like grits, pasta,, hot cereal. Even when I use the water heating option, which legthens the cycle, I still find stuck-on stuff on the pan, bowls, or flatware that were in contact with those types of food. This doesn't seem to happen with any of the Cascade or Electra-sol formulas. I gave Smart & Final a chance, and they failed. Haven't tried Wal-mart yet with this DW (worked fine with the KM machine), since it's not convenient to where I live.
