137108000 Frigidaire âŁWater Drain⢠Pump andâ Motor⢠Assembly⤠is an electromechanical âdrain pump module used to evacuate⤠wastewater â˘from a household appliance. The assembly typically combines a â˘small AC or DC electricâ motor, an impeller or volute, a âmolded housing⤠with inlet and âoutlet portsandâ mechanical seals or gaskets; together these elements convert âŁelectrical input â˘into hydraulic flow to moveâ standing water out of the appliance chassis â˘and into the buildingâ drain line.
Inside an â¤appliance the â˘unit serves âas the final stage ofâ theâ water-management system, removing wash, rinse or defrost water from the âtub or compartment. It interacts directly⤠with the drain⢠plumbing (hose and trap), the appliance⤠control board (which âsupplies drive voltage and â˘timing)and with sensors⣠that detect water level or flow; â˘it â˘also has mechanicalâ interfaces with mounting brackets and vibration âisolation. From a technician’s standpoint â¤the pump must meet required flow rateâ and head specifications, withstand the appliance’s duty cycle, âŁand maintain electrical⤠and liquid-tight â¤integrity while operating under typical temperature and debris âloads.
Inâ this article readers âwill find a âŁtechnical overview⢠of the pump’s function and⣠construction, âguidance on â¤compatibility andâ identification, âcommon failure symptoms and diagnostic⣠checks, practical troubleshooting stepsâ (electrical and hydraulic âtests)and key considerations âfor removal and replacement such⣠as connector types, mounting orientationand âŁsealing requirements.â The âgoal is to provide⤠technicians, engineers, âŁand⣠appliance â˘owners with⤠the technical context â˘needed to⤠diagnose issues and make â¤informed decisions âabout repair âorâ replacement without⢠prescribing specific brand recommendations.

Function âand⣠Role âof the Drain âŁPump âŁMotor⣠in Frigidaire Dishwashingâ Systems
the 137108000 â¤Frigidaire Water Drain Pump and Motor Assembly is the⤠rotating elementâ responsible âfor evacuating wash⢠and rinse water⢠from the dishwasher sumpâ through theâ drain hose⣠and check valve. the assembly âcombines a compact electric⤠motor, an integrated impellerand the pump housing; âthe motor converts âelectrical âenergyâ into rotational torque that forces water flow. During the drain step the control board applies mains⤠voltage toâ the â˘pump terminals, the impeller⢠generates the pressure differential âŁneeded to overcomeâ hose backpressure and the check valve âprevents residual waterâ from returning to the sump. Mechanical obstruction, a damaged impelleror⤠thermal/overload protection activation are common⤠causesâ of reduced or no flow even when the motor receives voltage.
- Symptoms of âpump issues: humming without flow, intermittentâ draining, visibleâ debris in the â˘filter or inletandâ leakage âat âthe housing or hose connections.
- Diagnostic checks: verify voltage⤠at the pump harness during âthe drain cycle, inspect⤠the impeller and inlet âŁscreen for obstruction, âand âŁconfirm â˘electricalâ continuityâ of the motor windings.
- Installation notes: ensure correct mounting orientation, drain hose routing to prevent siphoningand matching electrical connector/pinout for plug-and-play⣠replacements.
Compatibility for replacement requires matching âthe physical mounting, electrical connectorand hydraulic port locations ratherâ than âjust the part number; many technicians cross-reference â137108000 Frigidaire Water Drain âPump and Motor Assembly⢠with model-specificâ parts lists â¤to confirm fit. In practice, replacingâ the assembly âis typically performed⤠after isolating mechanical â¤blockage and verifying that the control board is commanding the drain function – for âexample, a technician may âobserve 120âŻVACâ (typical north Americanâ mains) âat âtheâ pump during⢠the drainâ command, remove the⤠lower âkickplate to access the pump âfor visual inspectionandâ replace the unit âŁif the impeller or motor shows corrosion,⤠seized â¤bearings, â¤or open windings. Simple â˘verification checks and correct⤠hose/check-valve orientation often restore reliable⢠drainage without âadditional â˘control-board âwork.

How the 137108000 Frigidaire âWater Drain Pump and Motor Assembly Operates Within the Appliance Plumbing and Electrical Circuit
The 137108000 Frigidaire⢠Water Drain⤠Pump and Motor Assembly â¤is a compact motor-driven impeller unit that evacuates condensate and defrost water from the refrigerator’s âdrain pan through the⢠applianceâ plumbing. Mechanically, âthe assembly mounts to theâ chassis and connects to the drain âhose via a hose barb; electrically, the motor is driven âby the refrigerator’s âcontrol board or⢠a relay so the â˘pump only energizesâ during defrost âor when condensate âcollection reaches a threshold. In operation the âcontrol⢠board provides line power to the pump motor⤠contacts, the impeller converts rotational energy into fluid âflow,â and⢠the outlet hose directs water⤠to a household drain or disposal area. Proper function depends on âŁcorrect mounting orientation, an unobstructed âinlet screen and âhoseand⢠a compatible harness connector⤠that matches the appliance wiring harness.
Technicians diagnose behavior by âŁisolating plumbing â˘and electrical â˘causes: a âdead pump with no motor spin âmay indicate an open winding or lost relay âfeed, while â˘a running motor with âŁno âflow⤠usually signals a clogged hose, frozen âpanor damaged impeller. Compatibility⣠considerations include matchingâ the â˘pump’s mounting flange, connector pinoutand âŁelectrical interface to the refrigerator model; replacing theâ unit withâ the correctâ 137108000 assemblyâ avoids misalignment âthat canâ cause vibration or âleaks. Practical troubleshooting steps frequently enough involve verifying voltage at the pump connector, inspecting the inlet strainer and outlet hose for⢠restrictionsand confirmingâ secure mechanical seals. Common symptoms and â¤features include:
- Symptoms:â humming withoutâ flow,intermittent âoperation,visibleâ leaks at hose connection.
- Features: motor-driven impeller, molded hose barb outlet,⤠mounting bracket âfor chassis attachment.
- Compatibility checks:â matching connector type â˘and mounting orientation toâ the appliance⣠harness⣠and frame.

Common âFailure Symptoms, Measurable⤠Diagnostic Indicatorsand Fault Isolation for the âDrain Pump and Motor
The 137108000â Frigidaire Water Drain Pump and âŁMotor Assembly is an electromechanical â¤unit âŁthat removes water by driving an impeller âthrough a motor âcoupled to the pump housing.â in service it is commanded by the appliance control to run during âdrain cycles;â proper fit requires matching the housing flange,mounting⢠points,and connector pinout to the appliance âharness. The assembly behaves as a âcombined mechanical hydraulic device and low-voltage/line-voltage motor: hydraulicâ problems (blocked â˘discharge hose,collapsed vent,foreign objects) present as restricted flow or stalled impeller,while electrical problems (open windings,worn brushes on universal â¤motors,or failed â¤windings on shaded-pole motors) âŁpresentâ as lack of rotation,excessive noise,orâ abnormalâ current draw. Verify⣠compatibility with the machine byâ comparing connector⤠type and electrical ratings before replacement or bench testing.
Diagnose failures using â˘measurable indicatorsâ and a systematic isolation procedure: check for command voltage at the pumpâ connector âduring a drain âcycle with a multimeter, verifyâ continuity âŁacross the motor windingsand measureâ running current with a clamp ammeter to detect increased⢠load from seized bearings or lodgedâ debris.⢠If voltage is âpresent but the motor does not spin,the fault is in âthe pump (mechanical jam,failed windings or brushes);⢠if⤠no âŁcommand voltage isâ present,trace â¤theâ harness back â¤to âŁthe control âboard â˘and test relays/fuse paths. A practical isolation sequence âis: observe⤠symptom, â¤duplicate it while monitoring âŁconnector voltage,⢠manually clear debris and spin the impeller to check for mechanical freedom, then bench-test the motor â¤withâ the⢠appropriate fused âsupply or substitute a known-good⣠pumpâ to confirm control output. Common, measurable indicators include abnormal amps, âŁopen-circuit ohmsandâ intermittentâ voltage at âthe connector; âŁuse these âto distinguish pump failure from wiring or control-board faults.
- No drainâ but motor relayâ outputs voltage – indicates pump/mechanical fault (jam âorâ open winding).
- Humming⣠sound with no rotation – suggests seizedâ impeller, bearing failureor ârotorâ shorting causing high current.
- Intermittent operation âor⣠resets – possible thermal cutoff, intermittent connectororâ control-board âfault.
- Leakage or water⤠in â˘motor⢠area – mechanical â¤seal failure or⤠cracked housing requiring replacement.
| Item | Description |
|---|---|
| Connector voltage | Measured during drain⤠command; presence confirms⤠control output âand shifts â¤isolation to the pump âŁitself. |
| Motor winding continuity | Low âohms expected; open or very high resistance âindicates winding failure.⣠Use manufacturerâ specs when⢠available. |
Compatibility,⣠Replacement Considerations, Stepwise⣠Installation Checklistand PostâReplacement âŁTroubleshooting
The âŁ137108000 Frigidaire water Drainâ Pump â¤andâ Motor Assembly must be evaluated for electrical, mechanicalandâ hydraulic⢠compatibility before replacement. Confirm the replacement matches the original part number orâ that published OEM crossâreferences are exact; pay particular attention âto the⢠pump housing geometry, mounting hole⤠pattern, inlet/outlet âdiametersand harness⣠connector pinout. Verify the⣠motor’s nominal â˘voltage and expectedâ current âŁdraw⣠match â˘the appliance⣠wiring (commonly 120 VAC in North âŁAmerica for many household units) andâ ensure the impeller orientation and⤠shaft coupling are the same so that flow direction and âtorque characteristics remain âunchanged. Physical⣠fit does ânotâ guarantee functional⢠compatibility-differences in impeller design or motor speed can cause underâdrain performance or increased noise even when the â˘assembly âŁbolts in place.
Use a methodical, documented replacement procedure and postâreplacement tests to âavoid⢠installation⢠errors and to diagnose remaining issues. ⣠Disconnect power and water â˘before starting, label harnesses, retain and inspect gaskets and clampsand check âhoses and filtersâ for blockages priorâ to installing the⤠new unit. After reassembly, run a shortâ cycle while observing âfor leaks, abnormal vibration, âunusual noises,â or intermittent operation; if problems appear, measure line â¤voltageâ at the pump connector, âcheckâ motor winding continuity âŁwith an âohmmeterand verify the impeller can rotate freely âby hand. Typical troubleshooting indicators include aâ humming motor (impeller jam or failed start circuit), no rotation with correct voltage⤠(mechanical seizure or open winding), âŁand lowâ flow with âcorrectâ rotation (restricted hose orâ mismatchedâ pump curve).
- Installation checklist: power off,document wiring,removeâ old âpump,inspect hoses/seals,install new pump with correct orientation,secure clamps,restore power/test cycle.

Q&A
What⤠doesâ the 137108000 âFrigidaire Water âDrain Pump and Motor Assembly do?
This assembly is the â˘drain pump and â˘motor used on many Frigidaire (and some Kenmore/White-Westinghouse) washing machines. It removes the wash water from the tub and pushes itâ out throughâ the drain hose during the drain and spin cycles.â The part includes the motor, impeller and pump housing as a single replaceable âŁunit.
What⣠are the common symptoms that this drain pump is â¤failing?
Common symptoms include: washer doesâ not drain â˘or drains very âslowly; the pump makes unusual noisesâ (grinding, rattling⢠or loud humming); visible leaking from the pump housing âor âaround âhose connections; âor the washer stops⣠mid-cycle on drain with an error code. Humming without water âflowâ frequently enough means â¤the motor isâ getting power but the â¤impeller isâ jammedâ or damaged.
how âcan I test the⣠137108000 pump to⢠determine if it âisâ bad?
First,always unplug âthe washer before any checks. Visually inspect the impeller area âfor debris, coins or lint. Remove the pump and check for mechanicalâ obstruction. With âthe pump disconnected, use â˘a multimeter to âcheck for continuity between the motor terminals-an open âcircuit usuallyâ indicates a failed âŁmotor. Also check that there is noâ continuity between any motor terminal and the metalâ housing (that would indicate an internalâ shortâ to ground). During a âdrain⢠cycle (with⤠power applied and safe procedure), you canâ measure whetherâ the pump receives line voltage â˘(in North âAmerica typically ~120 VAC) to determine whether the control board is commanding the pump.
Can I clean orâ repairâ the pumpor do I need âto replace the whole 137108000 assembly?
Minor issues such as smallâ blockages (coins, hair,⢠lint) or entangled threads can frequently enough be cleared and the pump will resume normal operation. However,if the impeller⢠or housing is cracked,theâ motor bearings â˘are seized,or the âmotor â˘windings are burned,replacement of the entire âŁassembly is the â¤recommended and practicalâ repair. âThe â137108000 is sold as a complete pump/motor⢠assembly â¤for â¤reliable replacement.
Is⢠theâ 137108000 an OEM part and will it fit my âwasher model?
137108000 is an OEM Frigidaire part number used in many frigidaire âand related-brand washers, â¤but compatibility âdepends⣠on the specific washer model. â¤Always verify fit byâ checking⤠your âwasher’s âŁmodel number against âthe part’s⤠compatibility list (available from Frigidaire,parts suppliers,or the â¤product listing). If you’re⣠unsure,â provide the⣠washer model âŁnumber to the parts supplier or technician to confirm compatibility.
What⤠tools and â˘safety steps areâ needed to âreplace the drain âpump â¤assembly?
Basic tools⣠typically include a⢠screwdriver or nut driver set,⢠pliersand possibly a âsocket set.â Safety âsteps:â unplug theâ washer andâ shut off water supply; have towels and a shallow container for residual water; labelâ or⢠photograph âŁwiring/hose â˘locations before disconnecting; relieve âpressure fromâ the âŁdrain â¤hose to avoid spills. âRemoval âusually requires âaccessing the pump â˘from⣠the front âŁor rear â¤panel, disconnecting the drain hoses and wiring harnessand âunbolting or unclipping⣠the pumpâ assembly. Reinstall the new pump in the⢠same orientation and verify all electrical and hose connections are secure before testing.
My pump âhums but does notâ pump⣠– should I replace it⤠or check âsomething else⤠first?
A humming motor that does ânot pump is âŁcommonly caused⤠by a seized⤠or jammed â˘impeller (foreign object âor debris) or damaged impeller blades.â First⢠power â¤down and check the pump for obstructions and free the impeller if possible. âŁIf the impeller spins freely by hand âŁand âthe âmotor still hums without âturning under power, theâ motor may have internal failure and the âassembly should be replaced. Also verify the pump is receiving voltage during the drain âcycle; if âit âis not⤠receiving voltage, the problem may be a control board, âŁtimer or â˘wiring fault rather than the pump itself.
Where can I buy the 137108000 pumpâ and is â¤there a warranty â¤or⤠aftermarket option?
You â¤can â¤buy the 137108000 from âŁFrigidaire âauthorized parts dealers, online â¤appliance parts retailersand some brick-and-mortar appliance⢠parts⢠stores. OEM⤠parts typically carry a manufacturer⤠or seller warranty (duration varies âŁby seller). âŁAftermarket equivalents are available âand may be⢠less expensive, but fit, quality⢠and warranty vary-choose a reputable supplierâ and verify return/warranty terms. âAlways check that the part matches your washer model before purchasing.
