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 or your appliance’s current dispenser cap is broken or lost, you can easily replace it with this item. This part measures approximately 1-1/2" D and is blue in color. Note that if your original cap was larger in diameter than this item, you will need to replace the entire dispenser assembly. Installing this part will require no disassembly or repair experience. Remember to unplug the dishwasher or shut off the house circuit breaker for the appliance before installing this part. 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.
