WD26X10013 GE Dishwasher Motor & Pump Assembly is an integrated motor-driven pump unit used in GE commercial and residential dishwashers. As a mechanical and electrical subassembly,it combines an electric drive motor,pump housing,impeller and seals into a single replaceable unit that is typically mounted in the dishwasher base or sump to circulate and move water within the appliance.
Inside the dishwasher system the motor and pump provide the hydraulic force that delivers wash and rinse water to the spray arms and directs spent water toward the drain path; it thus directly affects cleaning performance, water pressureand drainage.The assembly interfaces with the appliance control board for power and run-time control,the inlet and drain plumbing for water flow,and ancillary components such as the sump,spray arm assembly,float/level devices and heater (which conditions the water). Mechanical elements such as the impeller, shaft, bearings and seals are critical for maintaining flow and preventing leaks, while the electrical connections and motor windings determine current draw and operational reliability.
This article will describe the assembly’s functional role and internal construction, list common model compatibilities and physical fit considerationsand identify typical failure symptoms (such as loss of circulation, unusual noise, leaksor excessive current draw).It will also outline practical troubleshooting checks a technician can perform-visual inspection, checking for clogs or broken impellers, verifying power and continuity at the connectorand measuring motor behavior under load-and summarize replacement considerations such as correct part number matching, seal and mounting hardware, safety precautionsand when full assembly replacement is preferable to repair.

Function and Role of the Motor and Pump Assembly in GE Dishwashers
The WD26X10013 GE Dishwasher Motor & Pump Assembly is a combined electromechanical unit that provides both the wash circulation and the sump drainage functions in compatible GE dishwashers. The motor drives an impeller inside a molded pump housing to build the pressure required for spray-arm delivery during the wash and rinse portions of the cycleand the same or an integrated pump path evacuates water from the sump during drain commands.Mechanically, the assembly includes the motor rotor and stator, an impeller, a shaft sealand mounting interfaces; electrically, it uses the dishwasher control board to switch power and, in some designs, change direction or engage auxiliary windings for different operational modes. reduced flow, unusual vibrationor leakage are typically traced back to impeller obstruction, worn shaft sealsor bearing deterioration rather than to the control electronics when other subsystems are known good.
For replacement and troubleshooting, match the physical mounting, electrical connectorand port orientation of the WD26X10013 assembly to the machine to ensure proper fit and function; compatibility is determined by model fit lists or OEM cross-reference rather than visual similarity alone. Useful diagnostic checks include verifying motor winding continuity with a multimeter, inspecting the sump and impeller for foreign objectsand confirming that the control board is commanding the motor (voltage present during a run cycle). Typical operational indicators and basic checks include:
- No water circulation or poor cleaning performance – inspect impeller and inlet screen for blockageand verify motor runs when commanded.
- Loud grinding or humming noises – check for debris in the pump housing and for worn bearings or a failing shaft seal.
- Failure to drain or slow draining – confirm drain port clearance and that the pump can spin freely; verify control signals for drain mode.
- Visible leaks around the sump – examine the pump gasket/shaft seal and the mounting flange for cracks or improper seating.

How the WD26X10013 GE Dishwasher Motor & Pump Assembly Integrates with the Sump, Impellerand Control Electronics
The WD26X10013 GE Dishwasher Motor & Pump Assembly couples directly to the dishwasher sump and drives the impeller via a splined shaft and mating pump housing.The motor provides the rotational energy while the pump volute and impeller convert that rotation into the hydraulic flow required for spray arm circulation and sump evacuation; correct mechanical fit-shaft length,impeller seating,and gasket compression-determines seal integrity and prevents air ingestion that would reduce flow. Physically, the assembly includes the stator/rotor motor, the pump housing that bolts to the sumpand a seal interface; direct-fit replacements preserve the original geometry that the sump and spray system where designed around, so mismatched components can cause leaks, rubbing noisesor insufficient water pressure at the spray arms.
Control electronics supply mains power to the motor through relays or power devices on the dishwasher control board and typically do not provide closed-loop speed control, so faults appear as no-run, intermittent runor overheated motor rather than variable-speed symptoms.Technicians should check motor winding continuity, the thermal overload deviceand the harness connector to the control board during diagnosisand inspect the impeller and sump for foreign object obstruction or erosion. Replacing the assembly with the correct part restores the intended hydraulic characteristics and electrical compatibility; during installation, verify gasket seating, correct torque on sump fastenersand that the electrical connector is fully engaged before running diagnostic cycles.
- Mechanical interface: shaft spline, pump housing alignmentand gasket seating
- Hydraulic behavior: impeller vane geometry determines flow/pressure to spray arms
- Electrical interface: harness pinout, thermal overloadand relay/power output from control board
- Common service checks: continuity, visual debris inspectionand leak tests after installation
| Item | Description |
|---|---|
| Sump interface | Mounting boss, gasket compressionand fastener alignment to prevent leaks and seal the pump cavity |
| Impeller fit | Splined or keyed coupling to the motor shaft; vane profile controls flow rate and pressure |
| Control interface | Two- or three-wire harness to the control board; includes thermal cutoff/overload and mains connection |
Common Failure Symptoms and Diagnostic Indicators of Motor/Pump Malfunctions
The WD26X10013 GE Dishwasher Motor & Pump Assembly performs two coordinated functions: it converts incoming electrical energy into rotational motion and transfers that motion into hydraulic pressure to circulate and drain wash water. Failures typically arise from electrical faults (open windings, shorted windings, thermal cutoff activation), mechanical wear (worn bearings, seized shaftor broken impeller fins)or hydraulic blockages (clogged sump, check valveor discharge hose). These failure modes produce measurable changes in appliance behavior – no water circulation, weak spray, intermittent operation, unusual grinding or rattling noisesor visible leaks around the pump gasket – which help differentiate motor/pump faults from unrelated issues such as detergent dispenser or spray arm problems.
Technicians diagnose the assembly by combining visual/mechanical inspection with electrical tests and operational checks. Useful indicators include audible humming with no impeller rotation (locked rotor or seized bearings), a burnt-insulation odor (winding failure), lack of line voltage at the motor connector when the pump should be running (control board or wiring fault)and continuity results showing an open or shorted winding. Practical troubleshooting steps include powering down and manually spinning the impeller to check for free rotation, measuring AC supply at the motor connector during a pump command (nominally 120 VAC in North American systems)and checking winding resistance and insulation-to-ground with a multimeter. Replacing the pump assembly is appropriate when electrical tests indicate open/shorted windings, when the shaft has radial play beyond service limitsor when hydraulic damage prevents reliable sealing or rotation.
- Humming without rotation – check for seized shaft, blockageor thermal protector trip.
- Noisy grinding or rattling - inspect bearings, impeller finsand foreign debris in the sump.
- Intermittent runs or blown fuses – test wiring harness, connector pins, and motor insulation.
- Poor wash or slow drain – confirm impeller integrity and check valves,and clear discharge path.
- Burnt smell or visible smoke – remove power and replace motor windings or assembly; do not reuse.
| Item | Description |
|---|---|
| Motor electrical check | Measure AC voltage at the motor connector when the pump is commanded (typically 120 VAC in North America); absence of voltage indicates control/wiring fault. |
| Winding continuity | Use an ohmmeter: an open circuit indicates a failed winding; a near-zero reading or continuity to chassis indicates a short/insulation failure. |
| Mechanical inspection | Manually spin the impeller and check for axial/radial play; seized or excessively loose shafts require pump replacement. |
Compatibility across GE Models, Replacement Considerations, and Step-by-Step Installation and Testing Procedures
The WD26X10013 GE Dishwasher Motor & Pump Assembly combines the recirculation motor and drain pump into a single serviceable unit that supplies wash pressure and evacuates sump water. The assembly’s hydraulic performance depends on impeller geometry, motor speed, and housing clearances; mismatches in any of these (for example, a different impeller orientation or a rotor with altered shaft length) will change flow rate and can degrade cleaning or draining. Compatibility is determined by mechanical mounting points, hose diametersand the electrical harness pinout rather than by model year alone. When replacing the unit, technicians should compare the OEM part number, mounting-tab locationsand the connector arrangement on the existing unit; adapters or different gaskets are sometimes required between revisions of GE frames and tubs and using the wrong variant can cause improper sealing or premature motor wear.
Replacement and testing focus on preserving seals and verifying hydraulic and electrical behavior before returning the dishwasher to service. Start with proper isolation and draining, then remove the sump cover and unfasten the motor-pump assembly while noting hose routing and wire colour coding; transfer any required gaskets and clamps to the new unit to maintain sealing integrity. After reassembly, perform a leak and function test by running a short wash or diagnostic drain/recirculation cycle, observing for correct flow, abnormal noiseand leakage, and measuring motor current to confirm the motor is not overloaded.Practical checks include verifying that the drain path clears at the proper pump speed and that spray arm rotation and water distribution match factory behavior; if performance differs, re-check impeller orientation and electrical connections.
- Disconnect power and water supply,and remove standing water from the tub and sump.
- document hose locations, clamp typesand harness pinouts before removal.
- Remove access panels, unfasten mounting screwsand detach the motor-pump assembly.
- Transfer gaskets/clamps or replace with OEM equivalents; install new unit and torque fasteners evenly.
- reconnect the wiring harness, restore water and powerand run a short wash or diagnostic cycle.
- Inspect for leaks, verify spray arm rotation and drain operationand measure motor current under load.

Q&A
What is the WD26X10013 and what functions does it perform in a GE dishwasher?
The WD26X10013 is a motor and pump assembly used in many GE dishwashers. It typically contains the circulating (wash) motor and pump that force water through the spray arms and, in some designs, the drain impeller. Its primary functions are to circulate water during wash/rinse cycles and to move water out of the tub during drain phases (on models where the assembly includes the drain pump).
How can I tell if the WD26X10013 has failed and needs replacement?
Common symptoms of a failing motor/pump assembly include: loud grinding or screeching noises during operation, dishwasher not filling or not spraying water properly, water remaining in the tub after a drain cycleand a burning electrical smell.You may also see error codes on the dishwasher control panel related to circulation or draining. Before replacing, check for clogs in the sump/filters and visible debris in the impeller that could be causing the issue.
Can I test the WD26X10013 motor and pump myself? If so, how?
Yes, basic checks are possible. First, disconnect power to the dishwasher.Inspect the pump area for debris and manually spin the impeller to see if it is seized. Using a multimeter, you can check for continuity across the motor windings – a healthy motor typically shows low resistance (continuity); an open circuit (infinite resistance) indicates a broken winding. Do not apply mains voltage unless you are qualified; bench-testing with 120 VAC is hazardous and should be done only by trained technicians following safety procedures.
