Dishwasher Not Cleaning Properly? Diverter Motor W10537869 – Fix Poor Water Distribution Fast

If your Whirlpool or KitchenAid dishwasher is leaving dishes dirty, not spraying water to all racks, or running a full cycle with no cleaning results — the diverter motor is the most common cause. In most Whirlpool-built dishwashers, the diverter motor controls which spray arm zone receives water pressure during each wash phase. When it fails, water is routed to only one zone — or none at all — leaving dishes on entire racks completely unwashed. ⚡ Common failure point in Whirlpool, KitchenAid, and Amana dishwashers built on the same platform. Part W10537869 is the genuine OEM replacement that restores proper water distribution across all spray zones, bringing your dishwasher back to full cleaning performance.

❓ Is This the Right Part?

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

• ✔ Dishwasher powers on and runs a full cycle normally
• ✔ Water fills the tub correctly
• ✔ Drain pump works — water exits at end of cycle
• ✔ ONLY problem is dishes on one or more racks coming out dirty or unsprayed

🔧 Common Symptoms

• Top rack dishes come out dirty while bottom rack is clean (or vice versa)
• Dishwasher runs full cycle but dishes are not being sprayed with water
• Visible water in tub but no spray arm rotation on one level
• Grinding or clicking noise from the bottom of the tub during wash cycle

✔ If these symptoms match, the diverter motor is the most likely failed component in the wash system.

✔ In most cases, replacing this diverter motor restores normal spray arm operation and full cleaning performance immediately.
