675806 Whirlpool Dishwasher Pump Impeller and seal Kit is a âservice replacementâ assembly consisting of the âŁrotating impeller â˘element and the associated shaft seal(s)⣠and sealing âhardware used â¤in a dishwasher â¤pump. The impeller is the â˘driven hydraulic component that imparts kinetic energy to water inside the pumpâ housing, â˘while the⤠seal kit components isolate â˘the motor shaft and bearings from the wetted pump cavity to prevent leakage and contamination. âTogether these parts form the⣠basic wet-end service itemsâ for a centrifugal pump used in⢠domestic âdishwashing appliances.
Within⣠the appliance the⢠impeller â˘and seal interact directly with the pump housing, drive motor, and the⤠dishwasherâs water distribution⤠and sump systems.â The impeller controls flowâ rate and pressure delivered to spray â¤arms and circulation passages, â˘affecting spray pattern, soil⢠suspension andâ drainage; the seals prevent water âfrom entering âthe motor and bearing area, which would or else lead to electrical faults,⢠bearing failure, or corrosion.The âcomponent â˘therefore interfaces mechanically with the motor coupling and âŁpump mounting points and hydraulically with inlet and discharge â˘ports, making correct fit andâ sealing critical to reliable operation.
This article will describe the functional role of the 675806 impeller and⢠seal kit, outline âcompatibility considerations for identifying the correct pump assembly, list common failure symptoms (such as âreduced flow, abnormal noise, â¤vibration, and leakage), and provide practical troubleshooting steps to isolate⤠impellerâ versus motor or housing faults. It will also cover replacement considerations including⤠requiredâ disassembly sequence,inspection â¤of mating surfaces,seal⣠installation techniques,torque âand alignment notes,and post-repair verification procedures to help technicians,engineers,and âinformed appliance owners complete a⢠safe andâ effectiveâ service.

Function and Role of the Pumpâ Impeller and Seal Assembly in Dishwasher Hydraulics
The pump impeller converts â¤motor â˘torque âŁinto fluid flow inside the dishwasher sump, while the seal assembly isolates the motor and bearings from wash water. The 675806 Whirlpool Dishwasher Pump Impeller and seal Kit contains â¤the rotating impeller and the⤠radial face/lip seal components designed⣠to match the pump-housing geometryâ and shaft splines used in compatible â˘Whirlpool designs. The âimpeller’s vane shape and clearance to the diffuser govern delivered flow rate and pressure head; damage, material erosion from â¤abrasive debris, or distortion from heat reduces â¤volumetric efficiency and can cause cavitation, reduced spray pressure, and increased⣠motor âŁcurrent. The seal assembly prevents pressurized wash⣠water fromâ reaching the motor and âbearing surfaces; failure of the seal leads to âŁlubricant loss, corrosion of metal parts, and electrical faults in the motor housing.
- Reduced spray pressureâ or uneven dishwasher⣠cleaning â˘(worn or damaged⤠impeller).
- Visible water âŁor residue around the pump base after âŁa cycle (seal leakage).
- Unusual â¤pump noise or grinding (impeller⣠contact or foreign âobject damage).
- Elevated motor current draw or overheating âŁ(hydraulic restriction or leaking seal causing⣠bearing damage).
Technically, compatibility depends onâ matching shaft â˘spline profile, impeller outer diameter/clearance, and seal seat geometry; replacing only the impeller âwithout a compatible seal âŁcan leave aâ small⢠misalignment that accelerates wear. In practice, inspect the pump housing for scored âfaces, verifyâ the impeller spins freely on the shaft with correct⣠axial play, and check⢠the seal mating surface for flatness and burrs before installation. Correct installation⤠restores designed hydraulicâ performance, prevents⤠seal extrusion under pressure, and maintains motor loadâ within rated values-common repair scenarios include restoring cleaning âŁperformance after clogging-induced impeller damage or stopping progressive motor damage⢠by replacing a leaking seal.

How the 675806 Whirlpool âDishwasher Pump âImpeller and Seal Kit Works Inside the Appliance
The 675806â Whirlpool Dishwasher Pump Impeller and Seal Kit contains the rotating impeller and the sealing components that reside inside the dishwasher pump housing âŁand couple to the â¤motor âŁshaft. The impeller â¤converts motor â¤torque into a controlled water flow that feeds â¤theâ spray arms â˘(or, in some assemblies, assists âwith drain flow), and it’s blade geometry, clearance to the volute, and balance determine delivered flow rate and pressure. The⣠accompanying seal assembly-typically a dynamic rotary âŁseal with â¤a molded elastomeric element and a hard sealing âface-isolates the pump cavity âfrom the motor endâ bell to âprevent water ingress and⢠to maintain proper lubrication and cooling of the motor â¤bearings. Compatibility⤠depends âŁon the pump housing and motor shaft dimensions,⢠so technicians should âverify âŁthe dishwasher model and pump âassembly before installation to ensure correct fit and correct shaft orientation â¤for the impeller.
Inside operation relies on close mechanical tolerances: axial â˘and radial clearance between⤠the impeller and⣠housing control hydraulic efficiency, while the seal relies on aâ flat, clean sealing face and â¤correct spring preload to prevent leakage under pressure and â¤thermal cycling. Commonâ failure modes are abrasive wear⣠of the impeller vanes, plastic deformation â¤from cavitation â¤or foreign objects, and seal âface abrasion or lip hardeningâ leading toâ slow â¤leaks and eventual âmotor⤠contamination. Replacing bothâ components as a⢠kit restores hydraulic performance and sealing integrity âwhen the pump housing and motor âŁshaft are not scored or excessively worn; typical⣠service practice includes cleaning the housing, inspecting the shaft for pitting, and âverifying⤠that the impeller ârotatesâ freely with minimal radial play after installation.
- primary functions: restore water circulation pressure and prevent motor âcontamination from leaks.
- Symptoms of⢠failure: reduced spray pressure, water⣠pooling under âŁthe dishwasher, unusual⣠pump noise, â˘or âmotor overheating.
- Service notes: replaceâ both impeller and seal together,⢠inspect housing/shaft, and ensure correct seating and torque during âassembly.

Common Failure Symptoms,Wear Patterns,and Diagnostic Tests for Impeller and Seal Faults
The 675806 Whirlpool Dishwasher Pump Impeller and Sealâ Kit replaces the rotating impeller and sealingâ elements that establish hydraulic flow and prevent â¤water ingress âinto the⤠pump motor âand bearings. The âimpeller converts motor torque into â˘fluid motion; proper vane geometry and radial âclearance determine delivered⣠flow and pressure. Seals (an elastomeric Oâring and⤠a mating mechanical faceâ in⢠many designs) maintainâ a water-tight barrierâ at the shaft âinterface. When clearances grow, vanes chip, or â¤seal⢠faces score,⢠the pump shows measurable loss of throughput, increased axial play, âand elevated â˘bearing or motor â¤stress, soâ technicians commonly â¤replace both the impeller and seal together to restore original⢠clearances and âprevent secondary motor damage.
Common failure âsymptoms and wear patterns⣠are predictable and can âbe â¤validated with a few targeted diagnostic checks: visual âinspection ofâ the impeller âŁfor chipped or missing fins, âinspection of â˘seal faces for scoring or extrusion, and measurement of shaft axial/radial play. âŁPractical bench and in-situ tests include a dye-leak test â¤to confirm⣠seal leakage into the motor cavity, a timed-flow⢠test (collect â¤known volume⢠while the pump runs to quantify flow rate), â˘andâ a motor-current draw check with âŁa clamp meter-elevated current under no-load conditions indicates âhydraulic⤠binding orâ failing bearings. Typical symptoms to watch⢠for â¤are listed â¤below, followed by⢠a concise reference for quickâ troubleshooting.
- Reduced wash pressure or long cycle drainâ timesâ – often caused by erodedâ impeller vanes or âclogged â˘intake.
- audible âŁgrinding, cavitation, or high-frequency vibration – â˘indicates damaged fins âor foreign object âcontact.
- Visible âŁwater in the motor cavity or oil/burn⢠smell â-⢠consistent with seal face â¤failure and water ingress.
- Intermittent⢠pump stop/fuse trips or elevated motor current – suggests shaft âbinding, bearing wear, or trappedâ debris.
| Item | Description |
|---|---|
| Impeller wear | Broken âŁor eroded⣠vanesâ reduce volumetric flow and cause cavitation/noise; inspect for missing material and balance issues. |
| Seal failure | Scored or hardened seal faces allow leakage into motor âcavity and accelerate bearing corrosion and electrical faults. |
| Diagnosticâ tests | Dye-leak test, timed flow measurement, shaft play⢠check, âand⣠clampâmeter âmotor current readings provide quantitative âconfirmation. |
Replacement considerations, Model Compatibility, and Installation Procedures
The 675806 Whirlpool Dishwasher Pump Impeller and Seal Kit replaces the rotating impeller â˘and the stationary shaft sealâ inside the wash pump assembly; together these components control water circulation and maintain â¤the pressure differential between the motor/magnet assembly and â¤the wetted pump âcavity. âThe âimpeller transfers torque âinto water flow â¤and âŁwillâ produce reduced flow or⣠cavitation symptoms when worn, while a⤠degraded seal allows leakage into the motor cavity and typically causes oiling, motor overheating, âŁor electrical faults. For⣠compatibility,match âthe kit to the pump housing geometry,impeller hub â¤diameter,and seal bore rather than relying solely on model years: â¤many Whirlpool-built pumps share âcommon layouts,but variations in mounting flange,secondary retention clips,and motor shaft interface require⤠inspection of the pump moduleâ or OEM part number before âŁordering.
Installation requires basic appliance service skills and attention to âseal orientation âand debris management. Power â˘must be â¤disconnected and water drained, âthan âŁremove the lower âŁassembly and⤠access the pump housing; note impeller rotation and any spacer or shimâ locations before disassembly.Clean the pump cavity and inspect the motorâ shaft and â˘bearing⣠surfaces for wear – replacingâ the impeller and seal on a scored shaft will â˘not stop leaks. After installing the new âimpeller and lipâ seal (seal lipâ toward âthe wet side),reassemble retaining â¤clips and gaskets,run a âcontrolled test â˘cycle andâ observe for leaks and expectedâ flow patterns; if flow⤠is weak but no leaks are present,verify impeller clearance âŁand that â˘the sump inlet screens are free âŁof obstructions.
- Quick checks before ordering: confirm pump housing shape,impeller hub diameter,and seal bore dimensions.
- Common symptoms indicating âŁreplacement: reduced spray â˘pressure, grinding noises âfrom pump,â or oil/dispersion near the motor area.
- Post-install verification: leak test at rest and during⤠a short wash cycle; inspect motor currentâ for abnormal draw.
