Dishwasher Not Washing? Circulation Pump W11462455 – Fix No Spray & No Water Pressure Fast

If your dishwasher fills with water but dishes come out just as dirty as they went in, the circulation pump and motor assembly is the most likely cause. In most Whirlpool, KitchenAid, and Maytag dishwashers, the circulation pump pressurizes water and forces it through the spray arms at high velocity to blast food off dishes. When it fails — due to a seized motor, failed impeller, or burned-out winding — the dishwasher fills and drains normally but produces no spray action whatsoever. ⚡ The single most common cause of a dishwasher that fills but won’t wash in Whirlpool-built units. Part W11462455 is the genuine OEM replacement (and our XPart compatible alternative) that restores full water pressure and cleaning performance immediately.

❓ Is This the Right Part?

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

• ✔ Dishwasher powers on and runs through cycles normally
• ✔ Dishwasher fills with water and drains correctly
• ✔ Door latch confirmed OK — door registers as fully closed
• ✔ ONLY problem is no spray action, weak water pressure, or dishes not getting clean

🔧 Common Symptoms

• Dishwasher fills with water but makes no sound during the wash cycle (motor dead)
• Loud humming or buzzing without water movement (motor seized or impeller jammed)
• Dishes come out dirty after a full cycle — no spray arm pressure
• Grinding, rattling, or burning smell from the bottom of the dishwasher

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

✔ In most cases, replacing this circulation pump restores full spray pressure and cleaning performance immediately.
