The Dishwasher Rinse Aid Cap is part of the detergent dispenser and releases the appliance’s rinse aid during the cleaning cycle. If the detergent assembly of your dishwasher does not dispense the rinse aid properly, then this cap will need to be replaced. This item measures approximately 1-1/2" D and is blue in color. Installing this part will require no tools, disassembly or repair experience. Helpful Tip: We also recommend using affresh® Dishwasher Cleaner (item W10282479) to help remove limescale and mineral build-up that can be unsightly and affect your dishwasher’s performance. *affresh® brand products are owned and distributed by Whirlpool Corporation..
