Common Questions About Dishwashers

  • My glasses are coming out spotty, filmy. What's wrong?
    Anwer: For spotting only, use heated drying cycle or a rinse-aid product. For filmy, it could be too much detergent or a water flow restriction (more details below).
  • Do I need to pre-rinse my dishes before putting them into my dishwasher?
    Answer: No rinsing is needed unless your dishes sit for several hours.
  • There's water at the bottom of my dishwasher. Why doesn't it drain completely?
    Answer: All dishwashers leaves a small amount of water at the bottom of the dishwasher to keep the pump and seals moist.
  • What is the correct way to load a dishwasher?
    Answer: Dishes and cookware should have exposed surfaces facing the spray arms. Knives and other cutlery with wooden handles are best washed by hand because detergent, over time, can cause the wood to crack or become brittle. Other cutlery should be loaded with the end that touches food face up for better water circulation.

Dishwasher Tips

  • Keep dishwasher clean. Use Glisten (part no. 19080) for dishwasher cleaner and hard water spot remover. It removes cloudy film and spots from dishes and glassware.
    Using a good cleaner will help with dry time.
  • If gasket cracked, old or leaks out, McCombs sells a replacement door seal.
  • McCombs sells gasket sealant (part no. N80046) that sells for $6.26.
  • Also clean the inside of the dishwasher with a rag to preserve the existing door seal.
  • To help with a rusty rack, there is dishwasher rack paint called rack patch (DWR1WHITE). This dishwasher rack paint dries to surface as it dries overnight. Cost: $4.95.
  • Cleaning your filter will help the longevity of your dishwasher. Clean under your screen. You'll be surprised what you'll find, like bones, hair.
  • Have a look at a step guide showing you how to clean the dishwasher filter.
  • In order to keep your dishwasher filter from being overexposed with food and dirt, a thorough cleaning should be preformed at least once a month.
  • After you have cleaned the filter, mix together ½ cup of baking soda, ½ cup of salt and 1 cup of bleach. Pour this mixture into the bottom of the dishwasher and allow it to sit overnight. In the morning set your dishwasher to run a normal wash without any dishes in it to complete the cleaning process.

    Did You Know?
  • It turns out phosphates were a key cleaning ingredient, particularly in homes with “hard” water that's heavy in calcium deposits.

    Finding the model number
  • Model numbers are usually made up of numbers or a combination of letters and numbers. The dishwasher model number will appear on a laminated sticker or a metal plate.
    Model number can be found in the following places, including on either side of the inside edge of the dishwasher, on inside top edge of dishwasher door, on either side of the inside of door.
