WD26X10013 GE Dishwasher Motor â¤& Pump Assembly is a combined electric drive and hydraulic â˘unit used in many GE dishwasher models; it integrates the electric motor,pump housing,and â¤impeller(s) into a single serviceable module. As a mechanical subsystem⣠the assembly converts electrical âinput âfrom the appliance control into rotational torque âand fluid flow,providing âboth circulation forâ wash spray and,in many designs,the pumping action required for â˘drain⤠functions.
Inside the appliance the motor and pump assembly isâ mounted⤠in the sump area beneath âthe tub and directly interfaces with the spray arms, filters, drain âŁhoseand the dishwasher’s water-management components (float, check valveand anyâ pressureâ or temperature⣠sensors). Electrically it isâ indeed driven by âthe main control board through⣠start/run windings⤠or triac outputs and typically connects via a⤠multi-pin harness; mechanically it couples⢠to impellers, shaft seals and bearings that must maintainâ hydraulic pressure âand a watertightâ seal. Proper operation of this part is critical becuase inadequate â¤circulation pressure â¤or a failed pump will produce poor wash performance, inabilityâ to remove âsoil or drain water,⣠abnormal noisesor âleaks that can lead to secondary component damage or safety shutdowns initiated by the control âŁsystem.
In the following âarticle âŁreaders will find a â¤focused âtechnical overview of WD26X10013: âhow the unit functions,â compatibility and model cross-reference considerations, common failure âsymptoms and diagnostic checks, step-by-step â¤troubleshootingâ methods (electrical continuity and voltage checks, â˘inspection for mechanical obstruction or seal failure)and practical replacement considerations such as requiredâ gaskets, connector orientation, mounting procedures and post-installation testing. The âŁguidance is intended to help technicians,engineers and educated appliance owners make⢠informed service decisions⤠while observing standard safety precautions like â˘isolating power and water before inspection or replacement.

Function and Role of the Motor and Pump Assembly in Dishwashing Performance
WD26X10013 GE Dishwasher Motor & Pump Assembly âis âthe electromechanical⤠module â¤that generates the hydraulic flow and pressure required for spray-arm cleaning âŁand, â¤in many âinstallations, also âprovides the drain pump function. The assembly consists âof an electric motor â¤driving an impeller (or multiple impellers) housed in a âvolute, with shaft seals and bearings that isolate the motor from â˘detergents and water. performance of the assembly âdetermines⤠spray⣠velocity, turbulence, âand the ability to evacuate wash and rinseâ water; lower flow or reducedâ head pressure âfrom a worn impellerâ or failing motor typically shows âup as poorer soil removal and âlonger cycle times. âTheâ unit interfaces directly âwith the dishwasher wiring harness, mounting bracketsandâ the control⣠board, which âsupplies timed âpower pulses orâ continuous line voltage depending on the program stage.
- Reducedâ spray pressure or incompleteâ cleaning
- Loud bearing or grinding noise during operation
- Standing waterâ inâ the âŁtubâ after the â¤drain cycle
- Motor âhum with no rotation (impeller jam or electrical fault)
| Item | Description |
|---|---|
| Primary function | Convert⤠electrical energy to⣠hydraulic flow forâ spray⣠arms and facilitate drain flow where integrated |
| Common failure⢠modes | Impeller wear, shaft seal leaks, âbearing âŁfailure, electrical winding faults |
| Diagnostic checks | Visual inspection for debris, continuity âand insulation checks on windings, current âdraw comparisonand leak inspection |
| Compatibility considerations | Matching mounting âfootprint, electrical connector/harnessand â˘rated⤠voltage/current to the âdishwasher model |
Whenâ evaluating⣠replacement or troubleshooting, verify that the replacement assembly matches âthe originalâ mounting points and connector pinout so the control board and hose interfaces function âwithout modification. Technicians commonly confirm the fault by observing symptoms (no flow,noise,leak),isolating power,inspecting for foreign objects⤠jamming the⢠impeller,and âŁmeasuring â˘motor winding continuity and running current; a rising current draw under load often indicates bearing or⣠hydraulic drag.â In practice, replacing the assembly is⣠typically performed when mechanical wearâ or seal failure is evident, while âintermittent electrical faults may warrant testing the control⤠outputs and harness first to avoid replacing⢠a â¤good pump due to âŁupstream wiring âor relay failures.
How the WD26X10013 GE Dishwasher Motor & Pump Assembly Works Inside âthe Appliance
The WD26X10013 GE Dishwasherâ Motor & Pump⢠Assembly is an integrated⤠unit that âcombines an âelectric drive motor with⤠a pump housing and impeller geometry to move and evacuate wash water inside compatible GE dishwashers. Electrically, the motor receives singleâphase AC power from the control board and converts it into⢠rotational torque; mechanically, that torque is transmitted to an impeller that pressurizes⢠the circulation chamber and routes flow to the spray arms.The assembly also contains shaft seals and bearing surfacesâ to isolate the motor windings from the wet sump; correctâ orientation,mounting brackets,and matching electrical connectors are â˘required for âŁdirect replacement âin assigned appliance models to â¤maintain â˘hydraulic performanceâ and âprevent⤠leaks.
During a wash cycle the control board energizes the motor so â¤the pump can develop pressureâ and flow ârequiredâ for soil removaland during drain the pump or an internal drain path redirects water out throughâ the discharge. Typical operational behaviors include a steady torque under load,automatic⤠thermal âprotection âŁif â¤stalled or overloaded,and sensitivity â¤to hydraulic blockages-foreign debris or collapsed hoses reduce flow and increase motorâ load. Technicians evaluate the⣠unit by checking motor winding continuity, measuringâ current draw under load, inspecting the â¤impeller for damage or obstructionsand verifying seal integrity; examples of practical faults are noisy⢠bearings â(mechanical wear), leakage pastâ the shaft seal (water ingress), weak spray patterns (worn âŁimpeller or air intrusion)and âfailure to drain (jammed drain vane or misrouted discharge).
- Commonâ symptoms: loud grindingâ or whining, reduced spray pressure,â leakage at sump, noâ drain actionor motor not starting.
- Compatibility⢠considerations: confirm part number, connector âŁtypeandâ mounting points before replacement.
- Troubleshooting steps: inspect impeller/sumpâ visually, check continuity and⢠ampâ drawand verify dischargeâ path is clear.
| Item | Description |
|---|---|
| Motor and Impeller | Single assembly that converts electrical input into âpressurized flow to supply spray arms and evacuate water. |
| seals and Bearings | Shaft âsealâ prevents motor âcontamination; bearings support rotation âand are common wear âpoints that cause noise and failure. |
| Mounting & Electricalâ Interface | OEM âmounting brackets andâ connector configuration determine fit â¤and compatibility with specific GE⢠dishwasher models. |
Common Failure Symptoms and Diagnostic⢠Indicators for the Motor â¤& Pumpâ Assembly
The WD26X10013 GE Dishwasher Motor & Pump Assembly is an integrated ârotor, impeller(s)and pumpâ housing that⤠provides â¤the primary wash circulation and⤠pumping functions inside compatible âGE dishwashers.â mechanically it âmounts to the sump and connects⢠to the appliance wiring through a âmultiâpin⣠connector; â˘electrically the motor âis driven from the dishwasher’s supply circuits and controlâ relays. Typical failure â˘modes includeâ worn bearings or âa⣠seizedâ rotor, impeller damage or debris jamming the pump path, shaft âseal deterioration that allows water intrusion into windings, âand âwinding⣠opens or shorts. âThese faults manifest differently depending on whether the circulation or drain side is â¤affectedâ because the⢠assembly can drive â˘seperate flow paths or coupled impellers in the same unit.
- No water circulation âduring the wash cycle while the control⣠appearsâ to be operating.
- Humming or buzzing from the motor with noâ shaft rotation.
- Reduced spray pressure or âuneven cleaning indicating a partially âobstructed impeller.
- Excessive noise or grindingâ suggesting bearing failure or foreign objects in the pump.
- Visible leaks fromâ the pump housing or electrical connector âand intermittent operation.
- Dishwasher fills but fails âto drainor drains but doesâ not circulate-helps isolate which impeller is âaffected.
| Item | Description |
|---|---|
| Supply voltage | Verify line voltage at theâ motorâ connector during the expected cycle (control âmust âŁcall for motor). No voltage points to control/timer or⣠wiring fault. |
| Winding continuity | Measure motor winding resistance⢠with⤠an ohmmeter; an open winding indicates âelectrical failure, very low resistance or short âto chassis indicates a shorted winding. |
| Mechanical inspection | Rotateâ the impellerâ by hand⣠(with power disconnected) to check for free rotation and debris; resistance or⢠binding⢠indicatesâ mechanical seizure. |
For diagnostics start byâ confirming the control issues a run â˘signal âand then use a multimeter to verifyâ the presence and stability of the âdrive voltage at the assembly; â˘if no 120 VAC (or expected line voltage) is⣠present at the connector,troubleshoot the control board,relay,or wiring before replacing the pump. If⤠voltage is present but the motor only hums or â¤has no rotation, perform a resistance and insulation âcheck on the windings and⢠inspect the impeller and housing for blockages or damage-bearing noise or âa rough manual rotation generally means the unit ârequiresâ replacement. use symptom patterns to⤠narrow the fault: drain-only symptoms indicate the drain impeller âorâ path, circulation-only symptoms indicate the wash impeller orâ motor driveand â˘visible moisture around the âelectrical connector or unusually low insulationâ resistance suggests water intrusion â¤and imminent âelectrical failure.
Replacement Considerations and StepâbyâStep Installation Procedures
the WD26X10013 GE âDishwasher Motor & Pump â¤Assembly performs two linked⤠functions: the âelectric motor providesâ rotational torque while the pump section converts that rotation into fluid flow to circulate wash water and to⣠evacuate drain water. Functionally,the assembly’s hydraulic performance depends on impeller integrity,clear inlet/outlet passages,and a âŁproperly seated lip seal; electrical behavior depends on correct supply voltage,secure wiring,and unobstructed rotor rotation. Compatibility checks prior to replacement should include verifying the part number against the âappliance model,⢠confirming the physical mounting pattern and connector typeand â¤inspecting the seal/gasket interface and impeller orientation so the replacement matches âthe original flow⣠direction and mounting depth. In practice, âa technician â¤often sees low spray pressure from a degradedâ impeller, âŁa humming motor with no flow indicating a seized pump or obstructed impelleror intermittent operation⤠caused by a damaged wiring harness or thermal protector-these symptoms guide whether the entire WD26X10013 assembly âorâ just peripheral components need attention.
- Disconnect power and turn off the waterâ supply before⣠servicing;â confirm with a meter that the lineâ is de-energized.
- Drain standing⤠water from⤠the tub and remove â˘the lower accessâ panel to expose the pump housing and âmotor terminals.
- Document and label wiring connectionsâ or take photos, then disconnect â˘harnesses and remove mounting fasteners securing the assembly to the tub.
- Carefully âseparate⣠the pump from the tub flange, taking note of gaskets and spacer orientation; replace any compressed or damaged seals.
- Inspect the âimpeller and inlet screen for debris, reinstall the new WD26X10013 with identical âŁorientationand hand-start fasteners to ensure correct alignment â˘before torquing.
- Reconnect wiring ensuring tight, corrosion-free contacts and restore any retaining clips or strain reliefs; rotate the impeller by hand to check for âfree movement.
- Restore âpower and run a short diagnostic⢠or rinse cycle while⣠observing for leaks, unusual noise, âŁcorrect water flowand proper drain function.
- If â¤noise or poor flow persists, âre-check electrical supply, âmotor run capacitor⤠if fittedand â˘verify âexhaust/drain lines are clear before furtherâ teardown.
for reliable service, replace âcompressible seals and any associated mounting hardware rather thanâ reusing stretched components; reusing⤠a compromised gasket commonly causes âpost-repair leaks.â after installation, measure operating current and compare toâ the nameplate range and observe startup behavior: âa slow spin or excessive inrush can indicate internal mechanical drag âor incorrect supply. If the dishwasher shares a common junction with â˘other appliances, confirm âthe circuitâ capacity andâ that the branch circuitâ protections match manufacturer âspecifications. Document part orientation and torque notes for future⢠maintenance to reduce repeat âvisits.

|---|---|
| Electrical rating | Verify voltage and nameplate current⣠on the originalâ assembly; most âŁunits are⢠120 VAC in North American models-confirm before installation. |
| Sealing and mounting | Replace lip seals/gaskets and ensure the pump flange seats flush; â¤misalignment causes leaks and reduced hydraulic performance. |
Q&A
What is âthe WD26X10013 motor & pump assembly and what does it do in my â¤GE dishwasher?
The WD26X10013 â˘is the â¤dishwasher motor and pump assembly⣠(also called⢠theâ sump⤠or circulation âŁassembly) âused on many GE/Hotpoint dishwashers. âIt contains the electric motor â˘and the âŁpump âŁhousing/impeller that circulates wash â˘water to the spray⢠arms â˘and,â on some models, also worksâ with the âdrain path. Its job is toâ move water through the wash system so dishes are sprayed, rinsed and âdrained properly.
What are common symptoms that the WD26X10013 is failing?
Typical symptoms include:â no water circulation (dishes remain dryâ or are not cleaned), strongâ humming with no water movement, loud grinding or grinding-and-squealing noises coming from âthe⢠bottomâ of the⢠tub, washing but not draining (if drain function⤠is integrated), errorâ codes related to â˘water⢠circulation on the control paneland âvisible âleaks from the âsump âŁarea. Debris/jammed impeller can cause similarâ symptoms, soâ inspection is needed âbefore replacement.
How can I test the WD26X10013 motor & pump assembly before replacing it?
