675806 Whirlpool Dishwasher Pump impeller and Seal kit is a replacement âpump impeller and sealingâ assembly for compatible Whirlpoolâ dishwasher⢠pump housings. The kit typically⤠comprises a molded impeller â¤and one or more sealing elements (shaftâ seals, O-rings orâ gaskets) designed to restore the hydraulic and fluid containment âfunctions of the pump âŁsection. As â¤a mechanical subassembly, it is⢠a wear-item intended to be installed intoâ the pumpâ housing and driven by âthe dishwasher motor or pump shaft.
Within the appliance, this impeller âand â¤seal⢠kit converts rotary motion âŁfrom the pump motor into fluid flow â˘that supplies the sprayâ armsâ or âŁevacuates water â˘from the⤠sump, while the âseals prevent âŁwater âintrusion into the âmotor and gearbox areas. It directly⤠interfaces with the pump housing,â motor shaft, hose connectionsandâ the sump; its performance affects circulation⤠pressure, flow â¤rate⣠and the integrity of⢠the â¤motor bearings âand electrical components â¤by preventing leaks. Proper material compatibility and correct installation areâ essential becuase impeller âgeometry determines⢠flow âcharacteristics⣠and the âshaft seal is the primary âbarrier against water reaching the motor and electronics.
In âŁthis article you will find a technical overview of the 675806 kit’s function and typical construction, guidance on model compatibility and cross-referencing, common failure symptoms to recognize (such as reduced spray pressure, âunusual noise or visible leaks), diagnostic checks and troubleshooting approachesand practical replacement considerations such as inspection of mating surfaces, âŁseal orientation, debris removal âŁand basic âreassembly notes. â˘The⢠goal âŁis to⢠provideâ technicians, engineers and applianceâ owners with the technical context needed to assess pump âissues and perform aâ correct component replacement.

Functional Role of the Dishwasher Pump Impeller and Seal in Water Circulation and Sealing
The âŁ675806 Whirlpool Dishwasher Pump Impeller and Seal Kit replaces the rotating impellerâ and the fluid⤠seal that together control â¤recirculation flow and prevent sump water from enteringâ the motor compartment. The impeller mounts to the pump/motor shaft and converts rotational energy into axial flow that feeds âthe sprayâ arms; â˘its blade profile, balanceand axial clearance determine delivered pressureâ and susceptibility to clogging or cavitation. The ⢠seal â is typically a â˘spring-loaded mechanical face seal âwith a stationary â¤seat in the pump housing and a rotating mating face on the shaft assembly; correct face flatness, spring preloadand installation orientation are critical to maintain⢠a leak-tight barrier under varying temperature and pressure conditions.fit and dimensional compatibility with the pump housing âŁand shaft are â¤what make this kit suitable for specific Whirlpoolâ modelsand matching OEM geometry is necessary to restoreâ original performance after âŁservice.
- Common failure symptoms: âreduced spray pressure, âloud bearing or grinding noises, âŁand water intrusion into the motor cavity.
- Inspection points: impeller blade integrity and balance, axial/runout on the shaftand seal face scoring or rubber component deformation.
- Service tip: âŁreplace both components as a matched set toâ preserve OEM clearances and⣠avoid repeat failure.
Operationalâ behavior under load shows that a damaged impeller lowers âŁflow and can create asymmetric loads that accelerate wear in the pump â˘bearings, âŁwhile a degraded seal allows pressurized wash water to migrate to⣠electrical components and âŁcause corrosion or short circuits.Technicians shoudl visually verify impeller clearance to the housing and confirm the ârotating seal face spins freely âagainst its seat; gently rotating theâ shaft by âhand can reveal roughness or binding. After âinstallation,a brief leak test and a âŁshort âŁcycle run with visual inspection of the âmotor base and hose connections will confirm correct assembly and⢠that the⣠kit has restored expected hydraulic performance.

How the 675806 Whirlpool⢠Dishwasher Pump⣠Impeller and Seal Kit Works Insideâ the Circulation and Drain Assemblies
The 675806 â¤Whirlpool Dishwasher Pump Impeller and⤠Seal Kit replaces the rotating and sealing elements located inside the circulation and drain pump⤠housings. The impeller mounts on the motor shaft and converts motor torque into â¤a pressurized flow that feeds the spray arms or forces water âinto â˘the drain path; theâ seal isolates the motor bearings and armature â˘from sump water, preventing leakage and corrosion. â˘In typical Whirlpool âcirculation assemblies the⤠impeller is a molded plastic, multi-vane component that engages a keyed or splinedâ shaft hub, while the⢠seal is a radial lip âor mechanical-type element seated in the⣠pump volute – together they restore hydraulic performance and moisture protection when installed with correct shaft engagement and â¤clearances.
Hydraulically,â the â˘impeller createsâ a â˘pressure differential between theâ pump inlet and outlet; wear, chippingor clogging of the vanes reduces âŁflow, increases motor current and often causes cavitation or noise. Aâ compromised seal allows⢠water to bypassâ the pump housing and â¤reach the motor or bearings, â˘producing corrosion, âbearing failureand⢠eventual motor seizure. Technicians should inspect for âworn vane edges, scoring on the shaft or hub, âand⣠deformation of the seal lip during âdiagnosis; replacing both⣠parts addresses both loss of flow and leakage⣠rather than âtreating symptoms independently.
- Primary features: impeller restores flow and â¤pressure; seal prevents water ingress to motor/bearings.
- Common symptoms indicating replacement: decreased spray âstrength, dishwasher failing to drain, unusual pump noiseor visible oil/corrosion at the⢠motor end.
- Installation notes: ensure correct shaft orientation and full seating of the seal in the volute to⢠maintain â˘clearance and⣠avoid premature wear.
| Item | description |
|---|---|
| Impeller | Molded multi-vane rotor that mounts to the â˘motor shaft to â¤generate flow; damaged⣠vanes reduce hydraulic efficiency. |
| Seal | radial sealing element that prevents sump water from contacting motor components; failure leads to bearing corrosion and leaks. |
Common Failure Symptoms and⣠Diagnostic Tests for Impeller and Seal Wear
When a dishwasher⤠exhibits âreduced⢠circulation, âextended drain times, loud grindingor⤠visible leaks, wear of the pump impeller and shaft seal are frequent root causes.The â 675806 Whirlpool Dishwasher Pump Impellerâ and⢠Seal Kit replaces the ârotating impellerâ and the⤠elastomeric shaft seal that together maintain hydraulic âŁflow⣠and prevent wash water from entering the⤠motor chamber. Mechanically, worn impeller vanes reduce volumetric flow and pressure head, producing poor spray distribution and residual soil; a compromised seal allows water intoâ the motor cavity, leading to increased âcurrent draw, corrosion of bearingsand eventual⣠motor failure. Inspecting⤠the assembly after removal typicallyâ reveals chipped⣠or rounded vane tips, axial or radial play on⢠the impeller shaft,â or a flattened/hardened seal lip-each symptom correlates â˘to distinct performance losses and compatibility considerationsâ with the pump housing and⤠motor shaft â¤finish.
- Persistent loud motor noise or grinding duringâ drain/pump operation
- Slow⤠or incompleteâ drain cyclesâ and âŁweak sprayâ performance
- Visible water around the motor housing âor staining/corrosion inside âthe cavity
- Intermittent pump âstalling or⣠elevated current draw under load
- Physical evidence:⢠chipped vanes, âŁshaft wobbleor torn/hardened seal lips
| Item | description |
|---|---|
| Amp/current measurement | Use a clamp meter⢠on the pump lead; a⤠important increase versus⢠nominal indicates binding, worn bearings, â¤or seal drag. |
| Visual and manual spin test | With the pump removed, rotate the impeller manually-roughness, grindingor axial play indicate wear beyondâ acceptable tolerances. |
| Leak/pressure test | Run a short wash and inspect the motor cavity for⢠ingress; âstanding moisture or active dripping â¤indicates seal failure. |
Diagnostic procedure combines â¤simple functional checks and targeted disassembly: time a standardâ drain cycle â¤and compare against a âŁknown-good reference, measure pump current â˘under normal load, âand perform a hands-on inspectionâ of theâ impeller and seal â˘after removing the pumpâ housing. For example, a measurable increase in amp draw concurrent with reduced flow and visible impeller damage usually justifies replacement of both the impeller and the seal⣠as a set to restore â˘hydraulic performance and re-establish the OEM shaft-to-hub tolerances. Replacing the seal without addressing impeller wear (or vice versa)⣠often results in repeat service, so ârecord testâ values (cycle time, currentand observed play) to confirmâ the repair resolved the original diagnosticâ readings.
Compatibility, Replacement Procedures and Installation Considerations for the 675806 Kit
The 675806 whirlpool Dishwasher Pump Impeller and Seal kit replaces the rotating and sealing components that transfer wash water from the âpump to the spray arms andâ isolate theâ motor from the sump water. The impeller âconverts motor torque into fluid flow while âthe mechanical seal prevents water from entering the motor cavity; together they determine flow rate, pressure⣠headandâ leak resistance. Compatibility depends on pump housing geometry, shaft profile (smooth, D-flator keyed), impeller diameter âŁand trimand seal face âdimensions. verifyâ the kit against the pump assembly number stamped on the housingâ or the dishwasher model’s parts list, as visually similar impellers and seals⤠will not perform properly if the âshaft fit âŁor housing countersink â˘differs by a few⤠millimeters.
Replacement requires âattention to seal faceâ condition, shaft integrityand correct seating during âassembly. Removeâ deposits and corrosion from the â˘shaft and⤠bore before installing new seals; âany scoring or⤠out-of-round condition can cause immediate âfailure. â¤Fit the seal with its matingâ face dry⤠and press itâ squarely into the bore,then slide the impeller onto the shaft until it seats; do not overtighten the impeller-impeller âretentionâ is usually achieved by an interference fitâ or small snap feature rather than high torque. after reassembly, run a short wash cycle to verify there areâ no leaks, excessive vibration, âor unusual noiseâ which indicate misalignment or a damagedâ bearing; replace âtheâ pump â¤housing or motor if the âshaft shows axialâ play or rough rotation.
- Verify modelâ and â˘pump housing numbers before âordering⣠or âinstalling parts.
- Inspect shaft for scoring; â¤dress or replace if⤠out of round.
- Clean bore and lubricate elastomeric O-rings with silicone grease only.
- Seat seals⢠squarely; âavoid contamination of seal âŁfaces.
- Perform leak and vibration test after reassembly.
