Hi Suze, Thank you for your question. Unfortunately it looks like the cap is not sold separately from the whole dispenser. I hope that helps. Good luck with your repair.

Hi Linda, Thank you for your inquiry. The detergent dispenser is designed to release detergent into the dishwasher tub during the wash cycles and will typically have two compartments, an unsealed compartment for prewash and a sealed compartment for the main wash cycle. Verify that the dispenser is not simply clogged with caked on detergent and give it a good cleaning if necessary. Also check to make sure that the cover for the dispenser will open easily and is not damaged or broken. Check the release mechanism for worn or defective parts and replace if necessary. The rinse aid dispenser is designed to release rinse aid into the tub during the rinse cycle. Verify that the dispenser is full and is not clogged with detergent and verify that the cap is adjusted properly. The dispensers may be operated by either a mechanical devise or by a bi-metal release or wax motor devise. The rinse aid cap could be the reason why your dishwasher is not releasing rinse aid. The rinse aid dispensing cap is located on the inner door panel of your dishwasher. The rinse aid cap could be loose and may just need to be refitted, but could also be warped or damaged from the heat of the water in the dishwasher. Remove the cap from the door and inspect it for signs of melting or warping and replace if need be. If your dishwasher is not dispensing detergent, the spring and hinge pin on the dispenser door could be the problem. The dispenser door is spring loaded, and is held in the closed position by a catch. Check that the spring and pin are not bent or broken and replace if required. If the catch is not releasing the door, then you should inspect the timer, the bi-metal release or the wax motor. I hope this helps. Thank you and have a great day!

Hi Jeff, Thank you for your question. The cap is not sold separately and is only sold with the detergent dispenser. I hope this helps. Thank you and have a great day!

Remove the cap from the door and inspect it for signs of melting or warping. Also, if the water is not hot enough, this can cause the dishwasher not to clean the dishes properly. Turn the hot water tap on at the sink before starting the dishwasher and let it run for awhile. Once it is hot enough, start the dishwasher. I hope this helps. Thank you and have a great day!
