Dishwasher Not Cleaning or Leaking from Sump? Diverter Seal Grommet WPW10195677 – Fix Water Diversion Fast

Poor wash performance, water pooling in the bottom of the tub, or a dishwasher that leaves dishes dirty on one rack but clean on another almost always points to a failed diverter seal grommet. In most Whirlpool, KitchenAid, and Maytag dishwashers, this is caused by a failed diverter seal grommet. When it fails, water bypasses the diverter, spray pressure drops, and cleaning performance collapses — often accompanied by a slow leak at the sump. ⚡ Common failure point in Whirlpool-built dishwashers across multiple brand families. Part WPW10195677 is the genuine OEM replacement that restores proper water diversion, full spray arm pressure, and leak-free sump operation.

❓ Is This the Right Part?

This is the correct fix if ALL of the following are true:

• ✔ Your dishwasher powers on and runs a full cycle without error codes
• ✔ The wash pump motor runs — you can hear it operating during the cycle
• ✔ Water supply is confirmed OK — inlet valve and water pressure are normal
• ✔ Spray arm holes are clear — not clogged with debris or mineral buildup
• ✔ ONLY problem is poor cleaning performance, uneven spray, or a slow sump-area leak

🔧 Common Symptoms

• Dishes not getting clean — especially top rack — most common search: "Whirlpool dishwasher top rack not cleaning"
• Water pooling or standing in the bottom of the dishwasher tub after cycle
• Slow leak visible at the base of the dishwasher near the sump area
• Spray arms spinning weakly or not reaching full rotation
• Dishwasher runs full cycle but dishes come out with food residue
• Visible cracking, deformation, or displacement of the grommet seal in the sump assembly

✔ If these symptoms match, this is the most likely failed component in the system.

✔ In most cases, replacing this diverter seal grommet restores normal wash performance immediately.
