COMMENTS
l Best cleaning for heavily soiled items l Removes oils, perspiration, greasy
soils, and stains
l Prevents graying or yellowing
l Best for lightly soiled to moderately soiled items
l Safe for most fabric finishes
l Less fading and dye bleeding l Reduces wrinkling
l Best for very lightly soiled items l Saves hot water
l Best rinse water temperature
The washer features cold rinses for all wash temperatures. In addition, on some models, warm rinses are available with hot washes. Warm rinse water provides better water extrac- tion than cold rinse water, but may increase wrinkling when line drying. In cold climates, warm rinse water also provides a more comfortable temperature for handling the wash load.
Checking hot water temperature
Your hot water should be 54°C (130°F) or above. If you do not know your hot water temperature, you can check it easily. You may need to raise the temperature of your water heater. To check your hot water:
1.Fill a pan with the hottest water available from the faucet that fills your washer. NOTE: If you do not have a faucet at your washer site, collect the water from the faucet closest to your washer.
2.Place a candy thermometer or cooking thermometer in the water to check the temperature.
NOTE: In wash water temperatures colder than 21 “C(7O”F), detergents do not dissolve well. Also, soils may be difficult to remove, and some fabrics may retain wear wrinkles and may have increased pilling.
Water hardness
Many poor washing results can be traced to the hardness of the wash water. To check your water hardness:
l City water - ask the city water company.
l Well water - ask the local water authority.
Ask for the mineral content in grains/gallon or parts/million. If your water is more than 8 grains/gallon or more than 153 parts/ million, you should consider:
l Installing a water softener. l Using more detergent.
l Using a packaged water conditioner. l Not using soap.
