How do I use the Precision Dispense drawer?

Open the dispenser drawer and add laundry products as needed. You can add a Precision Dispense cartridge with liquid HE detergent (up to 18.5 oz for up to 36 loads), powdered HE detergent in the single-load compartment, liquid fabric softener, or liquid chlorine bleach. Then slowly close the dispenser drawer completely and make sure it is completely closed.
