How to Troubleshoot & Replace Whirlpool AP6014459 / WP99002654 Wash Arm Cap

Found that a lot of the moving parts were plugged and as a result dishes were not getting enough water pressure to clean. Replaced a lot of the moving water flow parts. Site even had how to do videos to help. Dishwasher works great now. Quick, inexpensive solution. 

Replaced pump and filter. 

Easily replaced with a standard socket set. Took about 2 minutes start to finish. 

Lower wash arm broken from knuckleheads misloading the silverware basket arrrrg! Replacement was easy-peasy only requiring the removal of one plastic cap nut to replace the arm. New arm and some stern looks have the dishwasher running again. Very good price and fast shipping on this part from appliancepartspros.com. 

Replaced both parts in about two minutes and tested. Lower wash arm spins now, and no longer hits the bottom rack!!!!! 

Very simple repair. Used some locktite blue to avoid future issues. 

Used part ordered 

Replaced lower wash arm which was not rotating due to build up of wash detergent Replaced docking station which was not sealing properly. 

Found that the lower wash arm was rotating slowly due to Hard Water build up. Prior to replacement ran an empty load using CLR in-order to breakdown the Lime and Calcium build up. Once that was completed and rinsed (several cycles) completely, I was able to install the parts in less than 5mins. and now the Dishwasher is like new, being a 10yr. old unit. Ron
