Open the dishwasher door and load the dirty dishes onto the dish racks.
Flip the latch or push the tab on the soap dispenser door, and open the dispenser door. Open the cap on the bottle of gel dishwasher detergent.
Place the top of the dishwasher detergent bottle over the soap dispenser cavity. Squeeze the bottle slightly to fill the dispenser, according to the volume of dishes you are washing. There are several lines or depths in the dispenser cavity. For small loads, fill to the first line; for large loads, fill to the top line.
Close the dispenser door, and push down until it locks into place. The door springs open during the wash cycle. If the door is not latched before starting the dishwasher, the gel will enter the dishwasher prematurely.
Fill the door-less dispenser with gel. This is your dishwasher's pre-wash dispenser, which is usually next to the wash dispenser. The dish detergent mixes with the incoming water immediately.
