Is This the Part You Need?
The W11414076 is the complete base pump and motor assembly — the unit that pressurizes water and forces it through the spray arms at high velocity. It integrates the sump housing, circulation motor, wash impeller, and shaft seal into one assembly. When it fails, the dishwasher fills and drains normally but produces zero wash action. If your dishwasher runs through its full cycle timer but dishes come out exactly as dirty as they went in, this is the part.
✓ Symptoms This Fixes
- Dishwasher fills with water but spray arms don't spin or spray
- Dishes come out dirty after a full cycle
- Complete silence during the wash portion of the cycle (motor dead)
- Loud humming or buzzing without water movement (motor seized or impeller jammed)
- Grinding or rattling noise during the wash cycle
- Weak spray arm pressure — dishes on the top rack not getting clean
- Water leaking from the bottom of the dishwasher (failed shaft seal or cracked sump)
- Dishwasher stops mid-cycle with water in the tub
- Error code related to pump or motor on the control panel

- Key Steps: Disconnect power and shut off water → Remove lower access panel and disconnect drain hose and water line → Pull dishwasher out from under counter → Lay unit on its back for sump access → Disconnect wiring harnesses and sensor plugs from pump assembly → Release sump locking tabs or mounting screws → Remove old assembly → Inspect sump cavity for debris or broken glass before installing new pump → Seat new W11414076 assembly with proper gasket fit → Reconnect harnesses and sensors → Reinstall drain hose, water line, and access panel → Return to upright, slide into place → Restore power and water → Run test cycle and check for leaks
- Safety: Always disconnect power AND shut off water before beginning. Do not over-tighten mounting hardware — cracking the sump housing will require a second replacement. Inspect the sump gasket and replace if worn.

Broken glass, fruit pits, toothpicks, and bone fragments are the leading cause of premature circulation pump failure. Before seating the new assembly, shine a flashlight into the sump cavity and remove every piece of debris you can find. A single shard of glass left behind will destroy the new impeller within weeks. Also inspect the wiring harness for heat or water damage — a damaged harness can cause repeated pump failures even after replacement. If the same pump has failed more than once, check the control board voltage output before condemning the pump again.
