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 (70°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.
