Function and Role⣠of the WD26X10013 GE Dishwasher Motor & Pump Assembly â¤in Water Circulation and Drainage
The WD26X10013 GEâ Dishwasher Motor â& Pump Assembly combines the drive motor and hydraulic components that create circulating wash pressure and move⣠wastewater out of the sump during the drain phase. The assembly’s motor drives an impeller (or a set of⣠impellers in a dual-stage design) âto produce the flow andâ pressure required by the spray arms; â¤an integrated âpump âpath and one-way valves route water to the sprayâ arms for⣠washing and then to the drain when the pump is switchedâ into theâ drain⢠circuit. Proper function depends on correct electrical connection, matching pump orientation and sealing surfaces to âthe dishwasher sumpand an impeller thatâ is free of damage or debris so the unit canâ meet theâ original â˘flow curve and pressure characteristics for the model it â˘serves.
Performance and failure⢠modes areâ largely mechanical or hydraulic: reducedâ spray pressure usually indicates worn or clogged impeller vanes, air leaks in⢠the suctionâ lineor weakened motor torque, while aâ non-draining machine often âpoints to a blocked drain path, failed checkâ valveor âa âseized drain impeller. Technicians should verify thatâ replacement assemblies match the original part’s mounting, connector type, â¤and electrical ratings to avoid⣠mismatched flow or overheating. Routine diagnosis can include a visual inspection of the impeller and inlet⢠screens, a spinning check âŁto âconfirm⤠free rotation, âand a simple current⤠draw test â˘to detect âŁexcessive load on the motorâ beforeâ ordering a replacement.
- Common⣠symptoms: weak spray,â intermittent draining, loud bearing ânoiseor motor humming without â¤water âŁmovement.
- Key checks beforeâ replacement: connector compatibility, â¤sumpâ sealing surfaceand impeller integrity.
- Diagnostic aids: free-spin test, current draw measurementand inspection for debris âor broken âvanes.

How the WD26X10013 â˘GE Dishwasher Motor & Pump Assembly Works: Internal Components, Impeller Dynamicsand Electrical Interfaces
The WD26X10013 GE Dishwasher Motor & â¤Pump Assembly combines⣠anâ electric drive and a centrifugal pump stage in a single compact unit to circulate wash water and evacuate drain water. The motor turns a⤠molded plastic ⣠impeller inside a volute-shaped housing, converting electrical power into hydraulic pressure that feeds the spray arms; the housing âgeometry and â¤impeller vane profile control â˘flow rate and pressure characteristics âŁacross the dishwasher’s â˘operating range.Electrical connection is via the appliance wiring harness and a multi-pin connector to the control board, which supplies mains-level â¤power (typically the appliance’s⤠120 VAC supply) and may monitor âmotor thermal protection or provide a switched â¤ground/neutral through aâ relay or solid-state driver.
- Motor rotor and stator (electrical drive)
- Impeller andâ volute (hydraulic⢠generation)
- Mechanical seal andâ bearing⣠assembly â(water â˘exclusion and rotary âŁsupport)
- Thermal âoverload/feedback and wiring harness (safety and control interface)
| item | Description |
|---|---|
| Impeller / Volute | Creates centrifugalâ flow; susceptible to clogging or vane damage that reduces spray pressure |
| Electrical interface | Multi-pin connector to control board; supplies mainsâ power and may carry thermal feedback |
Impeller dynamics determine performance: âdamaged or clogged vanes lower flow and increase motor load, while air ingestion or restricted inlet can cause cavitation and ânoise.⢠The mechanical seal and bearings⢠isolate the motorâ windings from water; seal failure permitsâ water entry that accelerates bearing wear and winding shorting. For â˘practical diagnosis, verify the â¤connector pins andâ harness continuity, check that âthe impeller rotates freely by handand listenâ for⤠bearing noiseâ or a humming motor that failsâ to develop speed-thes symptoms differentiate hydraulic blockage from⢠electrical⤠faults. âReplace â˘the âassembly only when mounting, connector pinoutand rotational orientation match the original to avoid â˘mismatches that can cause premature âfailure.
common Failure symptoms, Wear patternsand Diagnostic â¤Indicators of the Motor and Pump Assembly
The WD26X10013 GEâ Dishwasher â¤Motor & Pump Assembly combines⤠the wash motor, impeller, pump housingand seals into aâ single serviceable unit that both circulates washâ water and provides drain âforce on âmany GE dishwasher models. Functionally,the motor drives the impeller to generate the pressure and âflow required for spray âarms while⣠the pump housing maintainsâ hydraulicâ paths and contains⣠shaft seals and bearings; failure of any of these subsystems alters the assembly’s behavior. Before replacement, verify mechanical fit, âmounting pointsand that the electrical connector and nominal supply match the original unit; mismatched rotation,â voltageor connectorâ pinout will âcause immediate operational âfaults even â¤if the assembly is physically â¤similar.
- Humming or⣠motor not âturning – possible jammed impeller, seized bearingsor failed start capacitor/start circuit.
- Reduced⤠spray pressure or poor cleaning â- impeller erosion, partial blockage in the inlet or spray armsor internalâ leak past⤠worn seals.
- Grinding or metallic noise – bearing wear or debris âcontacting the impeller or housing.
- Water leaking at the pump junction – â¤cracked housing, degraded shaft seal,⢠or loose clamp/fastener.
- Intermittent operation or tripped breaker – electrical short in windings, degraded insulationor wiring/connectors with poor contact.
Diagnostic indicators are âbest confirmed byâ simple, measurable checks:⤠manually rotate⤠the motor shaft to detect roughness, inspect theâ impeller for nicks or material loss, pressurize the inlet to observe âleak pathsand measure motor winding resistance and â˘insulationâ with âa multimeter. â˘Practicalâ examples: a dishwasher âthat hums â˘but dose ânot pump frequently enough â¤has a mechanically seized impeller orâ a failed start circuit,whereas steady low â¤flow with normal motor sound âŁmore commonly indicates impeller wear or partial blockage.â Document observationsâ (noise character,flow rate,presence of leaks) to selectâ betweenâ seal/housing repair âŁand full assembly replacement.
| Item | Description |
|---|---|
| Humming without rotation | Impeller jamâ or failed start circuit;â check shaft for free rotation and test start components andâ winding continuity. |
| Low flow/poor cleaning | Impeller wear, debris in inlet⢠or spray arms,⤠or internal bypass; inspect â˘and measure flow after cleaning inlet screen. |
| External leak | shaft seal failure or cracked â¤pump housing; inspect âfor⣠visible cracks, replace seals or housing/assembly as required. |
Compatibility, Replacement Considerations, installation Stepsand Troubleshooting Procedures
The WD26X10013 GE âDishwasherâ Motor & Pump Assembly integrates the drive motor, impellerand sealing components into â¤a single unit that both circulates wash⣠water and provides drain pumping. Compatibility depends on âŁelectrical characteristics (household mains, connector â¤pinoutand control-signal arrangement), mechanical mounting (bolt pattern, flange â˘orientation, âand hose connections)and hydraulic âŁgeometry (impeller size and volute shape that determine flow and pressure).â Technicians should verify connector types, shaft orientation,â and âŁmounting dimensions against the âŁexisting part or⣠service manual; even âŁvisually similar assemblies can have âdifferent impeller clearances orâ seal arrangements that affect flow âŁrate and leak resistance. OEM WD26X10013⢠replacements âpreserve the original âimpeller geometry and seal locations, while non-OEM options may⤠require additional checks for fit and performance⣠before installation.
- Common failure symptoms: no â¤circulation,poor spray coverage,no drain,loud bearing noise,humming âmotor,or visible leaks.
- Pre-replacement âŁchecks: confirm voltage at the motor terminals, inspectâ screens and â˘hoses for clogs, verify control board outputs,â and measure motor winding continuityâ with an ohmmeter.
- quick installation â˘checklist: disconnect power â¤and â¤water,remove lower rack and access â¤panel,note wire/hose routing,detach clamps and mounting screws,install new gaskets and align mounting flange before torquing⢠fasteners.
During installation, âensure gaskets and hose clamps are replaced âŁor re-used only ifâ serviceableand hand-fit hoses to âavoid â˘twisting the pump housing; unevenâ torque on mounting screws âcan distort the pump â˘seal surface and cause â¤leaks. For troubleshooting, measure DC or AC voltage at theâ motor while a cycle is âŁcommanded,⣠listen for âfree rotation by hand to assess bearing conditionand compare winding⣠resistance to manufacturer specifications; a âhummingâ motor with correct supply voltage and open impeller clearance usually indicates⣠a â¤mechanical âŁblockage or seized bearings rather than an âelectrical control âŁfault. Replace the entire âŁassembly⣠if seals,bearings,or the impeller are damaged,since individual âinternal repair on this unit is typically not practical in âŁthe field.
| Item | Description |
|---|---|
| Electrical supply | Household mains (e.g., â˘120 VACâ in North America) via âŁdishwasher control relay – verify line at motor terminals during runâ command |

Q&A
What is the WD26X10013 and what does it do in my GE dishwasher?
The â˘WD26X10013 is âthe circulation motor and pump âassembly (sometimes calledâ the sump/motor âassembly)â used in many GE-brand â˘dishwashers. Its â¤primary job isâ to draw water from the tub and force it through the spray arms â¤to wash the âdishes. It does not generally include the drain pump (if your model has a separate drain pump).
What common âsymptoms â˘indicate the WD26X10013 is â˘failing?
Common signs include little or no water movement duringâ the wash cycle, loud grindingâ or whiningâ coming from the sump area, the dishwasher humming but not spraying, leaks âaround the base/sump, visible damage or corrosion to the pump housingor dishwasher error codes related to circulation. Some failures can also cause the unit to trip breakers or display motor fault codes.
How can I diagnose weather the pump/motor⣠assembly is the problem?
Start with simple â¤checks: remove and inspect the filter andâ spray arms for clogs, checkâ for foreignâ objects in the â˘sump/impellerand verify the circulation pump housing is not âcrackedâ or leaking.⢠With the dishwasher powered off and unplugged, use a â¤multimeter to check for continuity across the motor windings (you should see a low resistance reading,⤠not open circuit).â Also check for âa short to ground. During a running cycle you can measure for proper âsupplyâ voltage at the motor terminals (usually 120 â¤VAC on many GE âmodels)â – onlyâ if you are comfortable and take proper⢠safety precautions. if the motor⢠receives correctâ voltage â¤but does⤠not run,or if the motor⤠shows⤠an open winding or⢠short to âground,the â¤WD26X10013 likely needs replacement.
Can the WD26X10013 be repaired or should it be replaced as an assembly?
In most cases the WD26X10013 is replaced as a â˘complete motor/pump assembly. While some technicians can replace seals or impellers⢠in âcertain designs, many modern dishwasher âsump assemblies are not economical or practical to rebuild because seals and bearings are not easily serviceable. Replacing the entire assembly is â¤usually the recommended and reliable solution.
Whatâ are theâ basic steps andâ safety precautionsâ for replacing the WD26X10013?
Basic⤠steps: disconnect power and water to theâ dishwasher, remove the⤠kickplate⤠or toe panel, drain â˘remaining water, disconnect electrical connectors and water âŁhoses attachedâ to the⣠sump, remove mounting screws or clips that secure the tub/sump âassembly, swap out âthe old assembly for the new unit, reattach⢠hoses and âwiringand âtest for leaks and proper operation. safety precautions: always disconnect⤠power at the breaker (do ânot relyâ on the dishwasher’s plug âŁonly),â turn off the â¤water supply, label connectors or take photos before disassembly to ensure correct â¤reassemblyand use proper tools. If you are not experienced with appliance repair or working with mains voltage, obtain âŁservice from a qualified technician.
Will I need any othre parts or gaskets when replacing this âassembly?
Oftenâ the replacementâ assembly includes âthe main sump gasket and some internal seals, but you should verify âwhat the new part includes âbefore installation. It’s common practise toâ replace any visible O-rings, clamps,⢠or hose washers while you’re servicing the unit.Ifâ the dishwasher model uses a separateâ mounting bracket, spring â˘clipsor inlet/drain hoses that show wear, replace those as well to prevent future âleaks.
How do I test the motor windings with a â¤multimeterand what readings indicate a bad motor?
With power disconnected and the motor disconnected from the â¤harness, set a multimeter to the âohms⤠(Ί)â range. Measure between the motor winding terminals; you should see continuity and a⢠relatively low âresistanceâ (ohms value varies by motor design but âshould notâ be infinite). âŁAlso check each winding terminal âto the motor chassis⢠for a high resistance (ideally âopen/infinite);â a low resistance toâ ground indicates âan internal⤠short. An open⤠circuit (infinite resistance) between winding terminals⣠shows a⢠burned/open winding and â¤the motor is bad. Ifâ you are unsure âabout â˘readings,consult theâ appliance service manual or a technician for the specific expected values for your model.
Will replacing the⤠WD26X10013 fix leaks coming from⤠under the dishwasher?
Frequently enough leaks from the baseâ caused by a cracked sump housing, failed pump sealsor damaged gaskets are resolved by âreplacing the pump/motor assembly. However, confirm the leak source before ordering parts – leaks can alsoâ come from door seals, water inlet valves,â hose connectionsor the âdetergent dispenser. âAfter installing the new assembly, run⤠a few cycles and inspect carefully for any remaining leaks to ensureâ the root cause has been addressed.
