Whirlpool Dishwasher Circulation Pump Motor W11510029 — Restore Wash Circulation and Spray Pressure
W11510029 is a genuine Whirlpool dishwasher circulation pump motor used on select WDF331PAH-series dishwashers. It replaces discontinued OEM number W10854709.
The motor-pump circulates wash water from the sump through the spray arms. A defective or obstructed pump may cause weak spray pressure, poor cleaning, humming or no water circulation during the wash portion of the cycle.
Similar symptoms can also result from blocked filters or spray arms, wiring, the electronic control, low water level or another component. Standing water after the cycle normally requires separate drain-system diagnosis.
Confirm the complete dishwasher model before ordering. Disconnect electrical power and shut off the water supply before service.
❓ Is This the Right Part?
Inspect the pump and related components before ordering. This part may be correct if:
- ✔ Your dishwasher is a Whirlpool WDF331PAH-series model
- ✔ Your model number appears in the confirmed compatible list below
- ✔ The dishwasher powers on and the control panel responds normally
- ✔ Water fills the tub correctly at the start of the cycle
- ✔ The circulation pump has been confirmed as the fault — not the filters, spray arms, wiring, control, or drain system

🔧 Common Symptoms
- Dishwasher runs a full cycle but dishes come out dirty or greasy
- No water spraying from the spray arms during the wash cycle
- Humming or buzzing sound during the wash cycle with no water movement
- Water sits in the bottom of the tub and does not circulate
- Weak spray pressure or poor cleaning despite a full water fill
A failed or obstructed circulation pump is one possible cause and should be confirmed through model-specific diagnosis. The listed symptoms do not independently confirm pump failure — blocked filters, spray arms, wiring, the electronic control or low water level can produce identical results.
📦 Part Details
- Part Number: W11510029 (Genuine OEM — Current)
- Verified Old Number: W10854709
- Type: Dishwasher wash/circulation motor-pump — moves water from the sump through the spray arms during the wash cycle (not the drain pump)
- Brand: Whirlpool
A completely blocked sump filter causes identical symptoms to a failed circulation pump — no water movement, dirty dishes, humming motor. Before ordering, pull the lower spray arm and sump cover and inspect the filter for debris, broken glass, or a foreign object. If the filter is clear and the pump still won’t circulate water, the motor is the likely fault. Clearing a blocked filter takes 5 minutes and costs nothing — always check it first.
⚙️ Installation
Skill Level: Moderate. Disconnect electrical power and shut off the water supply before beginning. Remove the lower rack, spray arm, and sump cover to access the motor-pump assembly. Disconnect the wire harness and water connections, remove the old pump, and install W11510029 in reverse order. Follow the model-specific service diagram for your unit. Restore power and water, then run a short cycle to confirm normal operation.

💡 Pro Tip
A completely blocked sump filter causes identical symptoms to a failed motor pump — no water circulation, dirty dishes, humming motor. Before ordering, pull the lower spray arm and sump cover and inspect the filter for broken glass, food debris, or a foreign object. If the filter is clear and the pump still won’t circulate water, the motor is genuinely failed. Clearing a blocked filter takes 5 minutes and costs nothing — always check it first.
