Function â˘and Role of the Pump Impeller and⢠Seal in Whirlpool Dishwashing Systems
The ⢠675806 Whirlpool Dishwasher⣠Pump Impeller and âSeal Kit â˘supplies the wetâend components that translate motorâ torque âŁinto directedâ wash flow âand that⢠isolate the electric drive from â˘the sump.the impeller is a⢠vaned rotor mounted on the pump â˘shaft; its â˘vane âgeometry, balance, â¤and⣠axial⣠position control flow rate⤠and discharge â˘pressure delivered to the spray âŁarms. The⢠seal assembly⢠provides a fluidâ barrier between â¤the â˘pumped water and the motor/bearing compartment â˘- typically consisting of a rotating element and a stationary âseat or an elastomeric lip â- âŁand must âŁresist detergents, temperature cyclesand particulate abrasion. Confirmâ compatibility âwith⣠the dishwasher modelâ and pump housing by crossâreferencing theâ part number âand pump casting rather then relying solelyâ on⢠visual fit⢠of components.
impeller and seal degradation produce distinctâ operational symptoms⢠that aid⣠diagnosis: impeller damage lowers flow⤠and cleaning performance, while â˘seal âfailure generates â¤leaks and canâ lead to bearing âŁcorrosionâ or electrical faults.⢠Technicians â¤should inspect âthe impeller for chipped or missing vanes,axial or âŁradial play âon the shaft,and⢠the seal âŁfor hardening,abrasive wear,orâ surface scratches on the mating⤠faces. Replacement practice includes cleaning the pump cavity of debris, verifying shaft runout, seating⢠theâ seal concentricallyâ against a clean face,⣠and ensuring the impeller clears the âŁhousing without⣠rubbing; improper seating or⢠residual debris are common causes of â˘premature failure.
- Reduced⣠spray pressure or⢠poor wash â¤results
- Water pooling under the⢠dishwasher or⤠at theâ base of the pump
- Unusual motor âŁnoise,â vibrationor âthermal⤠cutoff âevents
- Visible impeller damage or axial/radial shaft â¤playâ on inspection

How the 675806 Whirlpool Dishwasher pumpâ Impeller and⣠Seal Kit Integrates and Operates Inside the Pump⢠assembly
the 675806 Whirlpool â˘dishwasher Pump Impeller and Seal kit is an OEM-style replacement designedâ to integrate directly into the⤠dishwasherS lower â¤pump assembly by⤠replacing the rotating impeller â¤and the rotating/stationary seal interface. The impeller slips onto the motor shaft (often keyed â˘or retained with aâ snap â¤ring)and⢠the seal assembly nests into âthe pump housing⤠so the polished ceramic or carbon mating face rotates againstâ the stationary seat âtoâ prevent â˘sump leakage. In operation the⢠impeller convertsâ motor torque into fluidâ flow through the wash and drain passages; theâ seal â¤keeps that hydraulicâ path isolated from theâ motor end âof the assembly. Materials and dimensional⤠tolerances⤠matter: the impeller geometry determines flow rate and pressure,⢠while âseal face flatness and elastomerâ boot fit determine⣠leak resistance and⣠serviceâ life under temperature and detergent exposure.
When âintegrating the kit into the pump housing, technicians should verify⢠shaft condition, seating lip integrityand that the impeller clears the âvolute⢠without rubbing; excessive â¤axial or radial shaft play will shorten âŁseal⣠life and reduce pump performance.â Common symptomsâ that indicate âimpellerâ or seal failure include persistent leaks at the base of the pump, low wash pressure with âŁintactâ motor operationand âunusual hydraulicâ noise âŁor cavitation from worn âvanes. Practical service steps include cleaning debris from the housing and cavityâ before installation, ensuring the seal faces are handled â˘only by their edges âand lightly lubricated with water for â˘initial assemblyand confirmingâ retention⢠hardware is⢠properly seated so âŁthe impeller’s axial âposition âmatches the original specification.
- Installation âtip: seat the seal flat and press⣠the âŁimpeller fully onto the shaft until theâ retention⢠feature engages.
- Failure signs: water leakage at⣠motor end, reduced spray arm â˘rotation, â˘or grinding noise fromâ the pump.
- Compatibility âcheck:â matchâ pump housing/model numbers⤠and shaft diameter before installation.
| Item | Description |
|---|---|
| Impeller | injection-molded thermoplastic⤠vaned rotor⣠that converts motor torque â¤into flow; profile affects flow and backpressure. |
| Seal | Rotating ceramic â˘or⤠carbon face âwithâ elastomeric â¤boot; provides rotating/stationary seal at the âshaft/housing interface. |
| Fit note | OEM-style replacement for âcertain Whirlpool-series pump housings-verify pump⣠model and â˘shaft diameter prior⤠to ordering. |
Commonâ Failure Symptoms and Diagnostic Tests â¤for Impeller âWearâ and Seal Leakage
The primaryâ signs that â¤require replacement of the rotating⢠components are a progressive loss of circulating⣠flow, unusual âmechanical noiseor visibleâ water escape at âŁthe â˘pump housing; the 675806 âŁWhirlpool âŁDishwasher Pump Impeller and â˘Sealâ Kit addresses both the⤠hydraulic and sealing elements that⤠commonly fail. âŁImpeller wear âŁmanifests â˘as eroded or chipped vane tips andâ increased clearance between â¤the impeller and diffuser, which⤠reducesâ delivered â˘flow â˘andâ can cause cavitation or turbulenceâ that shortens âmotor life. Seal failureâ typically presentsâ as âslow external leakage into⢠the lowerâ pump cavity or â˘sudden wash-water contamination of the motor compartment; confirm compatibility â¤with the âŁappliance by matching the pump housing âpart number⣠and service manual⢠fitment notes before ordering âreplacements or attempting installation.
Diagnose âŁwith a combination âŁof visual inspection andâ simple functional tests: inspect impeller âvanes and the elastomeric seals for radial tears, hardeningor extrusion; check for excessive play at theâ impeller⤠shaft (compare⤠to service manual⢠tolerances); run the pump under controlled conditions while monitoring flow and motor current âfor deviations from nominal.Common, easily observed symptomsâ include:
- Reduced spray andâ poor cleaningâ performance⢠during âthe wash cycle
- Loud grinding, hard bearingsor intermittent vibrationâ from the⢠lower assembly
- Visible water or staining beneathâ the pump⤠area âafter a cycle
- Motor overheating orâ tripping due to âhydraulic âŁbinding
| Item | Description |
|---|---|
| Visual â¤inspection | Look for eroded vane edges,⢠plastic⣠debris,⢠seal âcracks or â˘compression âset. |
| Flow/current⢠test | Reduced flow âŁcombined with elevated motor current indicates impeller âdegradation or partial blockage. |
| Dye/leak test | Introduce a âsmall coloredâ dye to â˘the sump and run pump; dye observed⢠outside⢠the âpump housing confirmsâ seal⣠leakage. |
Compatibility, Replacement Considerations, Installation Stepsand Troubleshooting Procedures for Affected Whirlpool Models
The 675806 Whirlpool⢠Dishwasher Pump âImpeller⢠and Seal Kit replaces the rotating impeller and⤠itsâ elastomeric sealing surface âinside the dishwasher wash â¤pump; â˘the impeller moves wash water through the spray âarms while⤠the seal prevents water from⣠entering the motor âand bearing â˘cavity. Functionally, âthe impeller⢠is a âmolded plastic component shaped toâ maintain â˘flow âand⤠pressure⢠at the specified pump speedand the seal provides⤠an axial barrier against âpressurized wash⢠water. Confirm⢠compatibility by â˘matching âthe pump⢠housing âinterface and shaftâ style on⢠the existingâ assembly-measurement of impeller âdiameterâ and inspection âŁof the motor shaft engagementâ (flat, keyed,⢠or splined) is the practical way technicians verify fit before⢠installing âthe kit on affected Whirlpool-family units.
- Common symptoms indicating kit replacement: reduced sprayâ strength,visible leaks⤠under âthe dishwasher,noisy or vibrating pump,and impellerâ damage âvisible after disassembly.
- Pre-replacement checks: inspect âŁinlet screenâ for debris, verify âpump housing integrity for cracks or⤠erosionand compare part numbers or⢠physical⤠dimensions.
- When troubleshooting after installation:⤠verify impeller seating and axial alignment, check for shaft⢠wobbleâ indicating bearing failureand â¤confirm âseal compression against a clean mating â¤surface.
For â˘replacement and troubleshooting, first disconnect power and⤠drainâ the tub; remove the âkick âŁplate and extractâ the âpump/sump assembly to gain âaccess to the impellerâ and⤠seal. Clean the mating surfaces and remove debris â˘before seatingâ the new â˘elastomeric seal flushâ in the housing, then slide the impeller âonto⤠the motor shaft â¤until fully engaged-note orientation and any keying âŁfeatures so blade faces match original installation.⤠After reassembly, run a short diagnostic cycle⢠withâ the dishwasher empty toâ observe âflow patterns and check for⢠leaks; persistent leaks after correct installation âgenerally indicate âa⢠damaged â˘pump housing or distorted seal seatâ and will require housing replacement.If circulation isâ poorâ despite a âvisually intact impeller,inspect âthe⤠pump inlet,motor bearings for â¤axial/radial play,and the driveâ coupling-these âŁare â¤common causes âŁof continued performance â¤issues â¤that âthe impeller/seal kit alone will not resolve.
| Item | Description |
|---|---|
| Impeller | Molded polymer impeller âsized⤠for the pump housing to restore designed flow and pressure. |
| Seal | Elastomeric axial⤠seal that mates to âthe â¤pump housingâ to prevent wash water ingress âto the motor area. |
| Retention hardware | Small â˘parts or rings ârequired to secureâ the â˘impeller in some pump designs; verify âŁpresence beforeâ reassembly. |
