Whirlpool Dishwasher Base Pump / Circulation Pump and Motor Assembly W11414076, Replaces W11122133

Genuine Whirlpool dishwasher base-pump, described by distributors as a complete circulation pump and motor assembly. It circulates wash water to the dishwasher spray arms; it is not the drain pump.

Is This the Right Part?

Common Symptoms

• Dishwasher fills but spray arms have little or no water movement
• Dishes remain dirty after a completed cycle
• Humming, buzzing, grinding, or rattling during the wash phase
• No circulation-pump sound during washing
• Weak spray pressure, especially at the upper rack
• Intermittent wash action when the pump operates inconsistently

Check Before Replacing

• Confirm that the dishwasher fills with water and that the problem occurs during the wash phase, not only during draining.
• With power disconnected, inspect the visible pump wiring and connectors for looseness, corrosion, heat damage, or water damage.
• Inspect and clean the dishwasher filters and spray arms before condemning the circulation pump.
• With power disconnected, check the sump and pump inlet area for accessible foreign objects such as broken glass or debris; do not force the impeller.
• If qualified and equipped with the model-specific service information, verify the pump receives the specified supply and perform the service-manual electrical test; do not test live wiring unless trained to do so.
• Check for leaks around the pump/sump area and distinguish this assembly from the separate drain pump.

• Photograph or label wiring and hose connections before disconnecting the original assembly.
• Inspect the sump and pump inlet for debris while the assembly is accessible, using only non-destructive cleaning methods.
• Seat the replacement assembly with its existing sealing surfaces properly aligned and reconnect all wiring and hoses securely; follow the model-specific service instructions for mounting details.
• Restore water and power only after all connections and access panels are secured, then check for leaks and proper spray action during a test cycle. Use a qualified technician if appliance removal, plumbing, or electrical work is outside your experience.
