Dishwashers and powdered water softener

firstkimNovember 25, 2009

The folks on the appliance forum don't seem to have an answer, so I thought I'd try here.

The water here is hard as nails and my landlady refuses to install a water softener, but that's another topic...

We have a brand-new Whirlpool dishwasher. I use Cascade powder in it, since a plumber once told me that the gels are a major cause of clogs in dishwasher drains. I also use a rinse aid due to the hard water. But my plastics are still covered with a white scum at the end of the cycle, and it doesn't matter which variation of the cycle choices I use. I've also increased the amount of rinse aid that's released during the rinse cycle. Would it do any harm to add a teaspoon full of Calgon or some similar water softening powder to the wash cycle? Would it help?

BTW - My water heater is set at about 140 degF and I normally use the hi-heat setting as well.

TIA for any help or advice!

Try "Glass Magic." Just follow the instructions on the box.

Look for in the automatic dishwasher detergent aisle of your grocery store. It used to come in a little green box.

My appliance repairman suggested I use the power ball type of (Finish or Electasol, can't remember) dishwasher tablets/packets. I switched from the Cascade I have used for decades, and that white residue is gone. I also use a rinse aid at his suggestion.

I checked. I use Finish powerball at the plumber's suggestion.
