Whirlpool WPW10195601 Spray Arm OEM Part

Initially thought it might be the door seal or float relay switch, so I replaced both with no fix. Then I noticed that one of the arms of the lower sprayer was separating along the seam, water must have been spraying out the side right at the bottom of the door. Tested first by putting a few rubber bands really tight which appeared to decrease the leak significantly. So I replaced the lower spray arm and the leak is gone. Something to consider if your dishwasher leaks, as I had not seen this specific cause/solution mentioned elsewhere during my internet searches.

Replaced the spray arm assembly. I found out BY ACCIDENT that this was the problem. I accidentally loosened the spray arm while checking the filters. The next load of dishes washed without any leaks, but after the load completed I noticed that the spray arm had fallen off. I read somewhere else that a cracked sprayer could cause this leaking condition as the water is sprayed in areas where it shouldn't be sprayed and there isn't any protection. Sure enough, close inspection of the spray arm revealed that the plastic was separating at the seam on the sides. Once the arm arrived (in a few days) it was a 5-minute replacement. Can be replaced easily by hand, without any tools.

I ordered a new Spray Arm and installed it myself in minutes.

Replaced the door gasket.and the spray arm.

Simple replacement
