How much detergent should I use?

The amount of detergent depends on water hardness measured in grains per gallon. For soft water (0-3 grains), use 2 teaspoons for Pots Pans and Heavy Wash cycles. For medium hard water (4-8 grains), use 5 teaspoons. For hard water (9-12 grains), use 8 teaspoons. For very hard water (over 12 grains), fill cups completely and a water softener is recommended. Always use fresh automatic dishwashing detergent as other detergents cause oversudsing.
