Hard Water contains minerals that can cause a film or deposit on the dishwasher tub and dishes. You may first notice this as "cloudy" glasses� To confirm if the film is due to hard water, soak a glass for approximately 5 minutes in undiluted white vinegar. Rinse and dry. If the film is removed, it is due to hard water (if not removed, see Soft Water). To correct: 1. Adjust the detergent amount to the degree of water hardness. (See pg. 6) 2. Check the water temperature. (See pg. 6) 3. Use a rinse aid to improve the sheeting action of the water. (See pg. 7) To remove film from the dishwasher: (To' one of the following.) 1. A damp cloth and mild scouring powder. 2. A half-cup white vinegar in a Normal cycle with
detergent in the MAIN WASH cup only.
Soft Water can promote etching if too much detergent is used, items are prerinsed or the water temperature is too high. Etching is a permanent pitting or eroding of the surface of the glassware. The beginning stages can be identified by a "rainbow" effect-- shades of blue, purple, brown or pink when the glass is held at an angle to the light. In advanced stages the surface appears frosted, spotted or cloudy. Etching can happen in any dishwasher and there is no relationship to the cost or quality of the glass. To prevent: 1. Adjust the detergent amount to water hardness. (See pg. 6) 2. Adjust the water temperature. (See pg. 6) 3. Do not prerinse. This aggravates etching.
Rust
Minerals
(iron and manganese) can turn dishes or the tub interior a brown, red or black color.
To remove:
To preyer/t:
1. Drain your home's water heater once a year to flush away any mineral deposits� 2. Check with a water treatment company like Culligan or Kinetico to see if a filter is needed in the home.
(Do not use this method on metal items�) 1. Use a rust removing compound like RoVer Rust Remover* (available from an authorized Maytag Parts Retailer by using Part No. 57961). Do not use RoVer with dishwashing detergent. 2. Fill both detergent cups with RoVer� Complete a Normal wash cycle. Follow with a short wash cycle using dishwasher detergent. 3. The only permanent solution is to install special filters which can remove iron and manganese from the water.
