How much detergent should I use in my Kenmore dishwasher?
The amount of detergent to use depends on your water hardness, which is measured in grains per gallon. The detergent dispenser has one main wash cup and a separate cup for pre-wash; consult your water hardness level to determine the proper amount for your specific water conditions.
