Open the GE dishwasher door and allow it to lay open, flat.
Locate the “Rinse Aid” compartment.
Unscrew the cover for the compartment by turning it counterclockwise with your hand.
Pour the rinse aid into the compartment until you see the marker reads “Full.” If your GE model does not have a marker, keep an eye on the rinse aid as you are pouring it, and do not allow it to overflow. If it overflows, wipe up the spill immediately.
Screw the cover back on the compartment by turning it clockwise with your hand.
