Mack H Longmont , CO February 03, 2019 Appliance: Bosch Dishwasher SHX99A15UC/19 Bosch Dishwasher Shx99a15uc/19: Rinse agent dispenser leaking don't need separate gasket though. How to replace Dispenser Gasket. Our 15 year old Bosch dishwasher started leaking Rinse Agent on silverware, leaving a sticky residue. The root cause is the wear on the little rubber seal on the rinse agent valve over time. The whole assembly is easy to replace, once the door skin is removed with just a little fighting with the metal clips as others have stated. My main reason for this review, however, is it was unclear to me if the dispenser gasket came with the dispenser or not. I erred on the side of caution and did order a gasket separately - which was unnecessary. The gasket comes with the dispenser. Hopefully some of you can avoid ordering an unnecessary spare gasket. Appliance Parts Pros did a great job - correct part came quickly with no hassles of any kind. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
