NOTE: It is normal for cover to open partially when dispensing detergent. The cover will open fully when the door is opened.

How much detergent to use

The amount of detergent to use depends on the hardness of your water. If too little is used, dishes won’t be clean. However, if too much is used in soft water, glassware will begin to etch.

l HARD-RII one or both sections to slightly below the top of the section (3 table- spoons) if water hardness is 8 or more grains per gallon, or 136 or more parts per million. Leave enough space in the cov- ered section to allow cover to close.

. MEDIUM-Fill one or both sections to the top of the second step (2 tablespoons) if water hardness is 5 to 7 grains per gallon, or 86 to 119 parts per million.

l SOFT-Fill one or both sections to the top of the first step (1 tablespoon) if water hardness is 0 to 4 grains per gallon, or 0 to 68 parts per million.

Find out your water’s hardness by asking your local water department, water softener company or county extension agent.

Using the rinse agent dispenser

Rinse agent dispenser

Keep the rinse agent dispenser filled with a liquid rinse agent. A rinse agent greatly improves the drying of dishes by helping water flow off them during the last rinse. A rinse agent also keeps water from forming droplets and drying as spots.

Release of a small amount of rinse agent into the rinse water is automatic in the final rinse of each cycle. For best drying results, check the dispenser periodically to see if it needs refilling.

To check dispenser

Remove dispenser cap. If dispenser is empty, an “E”will be clearly visible inside the dispenser.
