Function and âRole of the 137311900⣠Frigidaire Washerâ Pump in the Washer’s⣠Drain and Recirculation System
The 137311900 Frigidaire Washer⤠Pump â˘is the electromechanical component that handles âboth discharge and, on models equipped for it, recirculation of⤠wash water. Internally it typically âconsists of a small electric motor coupled to a plastic impeller in a volute⢠housing; theâ impeller generates the hydraulic flow that âŁforces âwater out of âthe tub â˘through âthe drain port⤠or â¤redirects water back into⢠the wash chamber when âa recirculation⤠path is engaged by⤠the washer’s valveâ or âdiverter. Control signals from the machine’s controller and inputs from⣠water-level⤠or pressure sensing devices determine whenâ the pump runs;â the pump’s flowâ direction and effectivenessâ depend on how âthe washer’s plumbing and valves route âthe discharge âand⢠recirculation â˘passages rather than⣠on⣠any change⤠to the⢠pump rotation itself.
technically,the pump’s behavior in service is governedâ by â¤hydraulic head,impeller â¤condition,and unrestricted â˘inlet/outlet passages; â¤wornâ bearings,a broken impeller,or â˘foreign-object blockage will reduce flow or stop pumping altogether while â¤electrical faults will produce motor hum⤠or open circuits. Compatibility considerations focus â¤on the pump’s⣠flange/mounting â¤pattern, inlet/outlet âŁdiameters,â and electrical connector pinout – âa replacement⣠must âŁmatch⣠these interfaces â˘to â¤avoid leaks or wiring issues. For practical troubleshooting:⣠verify the strainer â˘or trap âis âclear, inspect hoses for kinks, â¤check forâ continuity at the⣠motor terminalsand confirm the control âboard supplies the expected âvoltage⤠during a âdrain âŁcycle. These checks distinguish â˘between plumbing obstructions, control âŁfaultsand a failed pump assembly so⣠technicians can decide âwhether to clean, ârepairor install aâ direct-fit replacement.
- No drain or slow drain: check the inlet âstrainer and drain hose for⢠blockages â˘or kinks.
- Motor âhums but no flow: inspect impeller forâ debris or â¤mechanical seizure âand test motor winding continuity.
- Intermittent operation: verify connector â¤integrity and control-board drive voltage duringâ cycle.
- Leaksâ around pump housing: examine seals and mounting gasket alignmentâ before replacing âthe assembly.

How the 137311900 Frigidaire Washer âŁPump âWorks Inside the Appliance: motor, Impeller, Seals⤠and electrical Interfaces
The drain âassembly in a top-load Frigidaire reliesâ on a âcompact âwet-end⣠pump where a small â¤electric âmotor directly drives a molded⤠impeller to evacuate water; the 137311900 Frigidaire Washer⢠Pump is⢠a⣠direct-replacement âwet-end designed to âŁreplicate the pump geometry and mounting âinterfaces used in several Frigidaire machines. Inside⢠the unit the⤠motor shaftâ passes through â˘a âsealed bulkhead into the âŁplastic âŁpump housing: the rotating impeller âgenerates axial/centrifugal flow while⣠a⣠combination of âa primary mechanical seal and secondary O-ringâ prevents⣠water âingress into the motor âŁcavity. The impeller and housing profile⢠determine âŁflow⢠rate and⤠head; overtight⣠jams,lint accumulation or broken impellerâ vanes reduce throughput and increaseâ motor load,often producing aâ distinct humâ or rapid thermal cut-out cycles before full â¤failure.
- Motor: small âŁsingle-phase motor âŁthat converts electricalâ input⢠to shaft torque; failure â¤modes includeâ open â˘windings, â˘worn bearings âorâ thermal protectionâ trips.
- Impeller:⣠molded⤠thermoplasticâ vanes âŁthat createâ flow; susceptible to foreignâ object damage and imbalance.
- Seals:â primary mechanical seal âon the shaft and secondary elastomer O-rings to âŁprotect motor â¤internals from âmoisture.
- Electrical⤠interface: factory âŁplug/harness and motor leads connect to the âwasher control board and are used to apply mains voltageâ and feedback â¤for diagnostics.
- common âsymptoms:⤠no drain (open motor or⣠blocked impeller),⤠hum without rotation (mechanical jam or seized âŁbearings)and leaks at the motor-wet-end â˘junction⢠(seal failure).
For practical service, verify⣠compatibility â˘byâ matching mounting tabs,â outlet âorientationand connector type rather than relying solely on⤠partâ number; âwhen replacing the â¤pump technicians should âconfirm that the housing outlet aligns with the drain hose and that â¤the electrical plug âmates with the washer⢠harness. troubleshooting⢠stepsâ include a continuity checkâ across the motor windingsâ and a âlive-voltage check at the harness during â¤the drain âcycle âto distinguish⢠wiring/control faults from motor failures;⣠additionally⤠measure⣠motor current under load-elevated draw â¤withâ littleâ or no flow indicates mechanical binding orâ partial impeller â˘damage. If a seal is leakingâ or theâ shaft is corroded, replace the entire⣠pump assembly because on many⢠models the âŁwet-end âand motor are notâ serviceable separately⤠without specialized parts and tooling.
Common â¤Failure Symptoms and â˘Measurable Diagnostic Indicators for â˘Pump Performance
Theâ 137311900 Frigidaire Washer Pump moves wash water from the tub⤠to the drain â˘using âŁa⤠small âelectric motor and molded impeller assembly. Typical failure modes âinclude â˘impeller blockage âŁor breakage, seized bearings, wornâ seals causing âŁleaking, âand âelectricalâ faults in the âmotor windings or connector.⤠Technicians can correlate â¤observed symptoms with â˘measurable diagnostic âindicators: abnormal⤠current draw (measured with a clamp meter), â¤unexpected⢠electrical⤠resistance across â¤the motorâ leads (measured with anâ ohmmeter), a lack of measurable discharge flowâ at the pump outlet (measured by temporarily routing⤠discharge to a âcontainer), â¤and audible vibration or grinding that indicates mechanical damage. Practical examples: a⤠humming pumpâ that draws higher-than-normalâ current butâ produces no flow frequently enough indicates⣠an internal jam âor âbroken impeller, while normal current with no flow⤠suggests a hydraulic blockage downstream or âa⢠detached impeller.
- No âdrain with motor hum – measure current; elevated â¤amps with stalled⤠shaft⢠indicates mechanical seizure or jam.
- Intermittent operation – check connector continuity and voltage âŁat the pump⤠during a drain cycle⤠to isolate wiring or control-board faults.
- Low flow or â¤slow draining – âperform a simpleâ flow test at the â˘outlet and inspect impellerâ and inlet screen for debris.
- Excessive vibration or noise – inspect⣠bearings/impeller and compareâ motor resistance to vendor specificationsâ to detectâ winding⢠degradation.
| Item | Description |
|---|---|
| Current⣠draw | Use a clampâ meter during a drain cycle;⢠compare to service data⢠or a known-good unit to detectâ overloads or stalls. |
| Flow output | Measure discharge volume⣠per minute â˘or visually confirm flow; low/no flow with normal âŁcurrent⢠points to hydraulic blockage or impellerâ failure. |
| Electrical resistance | Measureâ motor windingâ ohms with an insulatedâ ohmmeter; â˘open âor shorted windings indicate motor failure. |
Diagnosing pump âproblems requires combining electricalâ and hydraulic checks and âunderstanding compatibilityâ constraints of replacement parts. For theâ 137311900 âŁFrigidaire Washer Pump, âŁverify that mounting⣠tabs,â shaft orientation, â˘and electrical connector âmatch the â˘cabinet harness⢠before â˘swapping units; bench-testing a removed pump at line voltage can confirm operation butâ should be performed â˘with⤠proper isolation and safety precautions. When measurements deviate from expected valuesâ – âsuch as, correct line voltageâ present but no continuity or excessive resistance across the motor leads, âor normal electrical parameters but no⤠hydraulic⤠output – âŁreplacement⢠is warranted because those â˘conditions⤠indicate â˘internal mechanical failure orâ motor winding⣠damage rather â˘than⢠a simple â˘wiring or control⣠issue.
Compatibility, Replacement Considerations, Installation Steps and Troubleshootingâ Procedures for the 137311900 Frigidaire âWasher Pump
The 137311900 âFrigidaire âWasherâ Pump is â˘a motor-driven⣠drain âpump assembly âŁthat evacuates wash and rinse âwater throughâ theâ washer’s drain âsystem. â˘Compatibility depends on matching⢠the physical mounting, inlet/outlet hose â¤diametersand the âŁelectrical connector type rather than model yearâ alone; âtechnicians should âverify that the replacement has theâ same âmounting âtabs, blower-style impellerâ orientationand two-â or three-wire⣠harness as âthe original. Functionally the assembly contains a â˘sealed motor and impeller; common failure modes âare mechanical blockage⣠(coins, âfabric debris), impeller breakage, seal or⤠housing leaksand electrical faultsâ in the motor windings orâ thermal protection. When evaluating replacement options,⢠compare OEM⣠part geometry and âŁconnector pinoutâ to avoid âadapting hoses or using nonâcompatible harness adapters thatâ can âcause âŁleaks or improper pump rotation.
Installers⤠should âfollow safe, stepwise procedures⤠and perform electrical and flow diagnostics during commissioning.Common⢠practical steps include⤠isolating mains power and draining residual water, documentingâ hose and â¤wire locations âbefore disassembly, removing hose clamps âandâ fasteners, transferring any inlet screens or gaskets to âŁthe new assembly, â˘and torquingâ mounting hardware â¤to the washer âmanufacturer’s specification toâ maintain seal compression.⤠For troubleshooting:⢠check for voltage at the pump connectorâ during âŁa drainâ command, inspect the impeller area for obstruction if theâ pumpâ hums without pumpingand pressure-test hose â˘jointsâ for⣠leaks after â¤reassembly. Simple checks such asâ clearing the coin trap,⢠testingâ motor⤠continuity against manufacturer values, âand running a short drain âŁcycle will distinguish hydraulic blockages from electrical faults⢠and guide whether â¤a⤠full pump replacement is required.
- Disconnectâ power: De-energize the washer âŁbefore any removal or âdiagnostics.
- No drain – check drain hose â¤routing, inlet screen, âand pump inlet for clogging.
- Pump hums but no flowâ – inspect impeller for jamming or broken âblades;⣠verify presence⤠of commanded voltage.
- Leaking at pump – inspect gasket, clamp seating, â¤and replace deteriorated seals or housings.
- Intermittent⣠operation – test harness âŁcontinuity and connector⢠corrosion before replacing âthe pump.

Q&A
What is Frigidaire part 137311900?
Part 137311900 isâ the drain pump assembly âŁusedâ on⣠a number of Frigidaire/Electroluxâ (and some rebranded) washing âmachine models. It⢠contains â˘the motor and impeller that remove water from theâ tub during âthe drain cycle. To be⣠sure it is the correct partâ for your machine, checkâ the washer âŁmodel âŁnumber and the OEM parts list or an â¤authorized parts reseller.
What are the âcommon symptoms â¤of aâ failing⢠137311900 â¤pump?
common signs include: washer won’t drain or takes much longer to drain,â water remaining âin the tub after theâ cycle, loud grinding or rattling noises during drain, a⤠humming sound without flow âŁ(motor tryingâ toâ run), leaks near the pump areaor â˘washer giving a drain-related â¤error code. âThese symptoms can also be caused âby clogs or hoses, âso inspect those first.
How⢠can I test the pump to see âif it’s bad?
First unplug the âwasher and âshut off water.â Inspect⤠and remove⢠any visible⣠debris⢠from the pumpâ inlet and hose. Manually â˘spin the impeller-if it’s stuck or binds, that’s a problem. For electrical testing, disconnect the âpump wiring and use âa multimeter to check for⣠continuity across the pump âmotor leadsâ (a few ohms âto tens â¤of⣠ohmsâ is âtypical for a good motor; an open â˘circuit indicates a failed winding). Youâ can also, with proper safety precautions,⢠measure whether the control is sending voltage to the pump during a drain⣠cycle-if voltage is present and the pump âdoesn’t run, the pump â¤is bad.
How âdo I⢠replace the â137311900 pump?
General steps:⣠unplugâ the washer⣠and turn off water. âDrain remaining water using the âdrain âhose or⢠by âsiphoning. âAccess theâ pumpâ (locationâ depends on âmodel-frontâ or⤠back panel removal might potentially be required).â Disconnect the electrical connector(s) and remove the inlet/outlet hoses (have towels ready). Unbolt or unclip the pump assembly and remove â˘it. âInstall⤠the new pump in theâ reverse⢠order, making sure hose clamps are tight⣠and âelectrical⤠connectors âare secure. Test â˘by â˘running⢠a â¤drain/spin cycle. Always follow your âmodel’s service manual and observe electricalâ andâ water-safety â¤precautions.
Can I repair⣠the⣠pump,â or⤠do I have to replace the â˘whole assembly?
Often the mostâ practical fix is to replace the entire pump assembly. Minor issues like âdebris âblockage, â¤a bent impelleror a loose hose â˘clamp can be repaired. However, when âtheâ motor windings, â¤bearingsor internal seals haveâ failed, rebuilding â¤the â¤pump is âusually not cost-effective⣠or âconvenientâ compared with âinstalling âa new OEM or high-quality aftermarket assembly.
Why does theâ pump hum but â¤not pump âwater?
A⤠humming motor â˘usually means the âpump â˘is receivingâ power but the impeller is jammed⣠or the motor⢠has seized/failed. Check for foreign objects in the pump inlet or impeller housing,⤠inspect the impeller for⤠damage,⣠and ensure the shaft turns⤠freely. If the â˘impeller and shaft are free but the pump still hums andâ doesn’t move water,⢠the motor is likely âŁfailing⣠and the pump â¤should be replaced.
Will replacing the pump stop a leak under the âwasher?
Possibly. âIf the⣠leak is âŁfrom theâ pump housing or the pump’s seals, âreplacing the pumpâ will usually âstop the leak. However, leaks can also come from looseâ hose clamps, cracked hoses, tub-to-pumpâ bootor âa cracked tub/housing. Inspect hoses, clampsand âthe⤠surrounding area to confirm the âŁpump is the source before spending on a replacement.
how much does part âŁ137311900â cost âand where should âI buyâ it?
Prices âŁvary⤠depending on supplier and whether it’s OEM or aftermarket; expect a typical range from roughly $30 to $120. Buy from reputable sources: frigidaire/Electrolux authorized parts dealers, âmajor appliance-parts websites, â˘or local appliance parts stores. Verify compatibility with your washer model number and checkâ the return policy⢠and warranty before purchasing.
