137311900 Frigidaire Washer Pumpâ is a âspecific drain pump assembly usedâ in Frigidaire âŁwashing machines; it is an electromechanical component that combines a smallâ electric motor, an impeller âŁand aâ molded housing to move wash and rinse water out of âthe âŁtub and into theâ household drain. As a⤠mechanical subsystem ofâ the appliance,⣠the pump typically â¤mounts⤠to â¤the base or⣠sump area of the washer⤠and âŁprovides the⤠hydraulic â¤flow âand pressureâ required during drain and spin cycles. the component is identified âby â˘its â˘part ânumber to ensure âproperâ fit,⣠electrical characteristics and mounting alignment when⢠servicing or replacing the unit.
Inside the â˘appliance the pumpâ interfaces directlyâ withâ the tub/sump, drain hose and âexternal plumbingand it⢠is controlled âŁindirectly âŁby the âwasher’s main â˘control board and âŁwater-level â˘or pressure sensingâ systems. Whenâ the âcontrollerâ issues a drain command the⣠pump motor receives power through the wiring⢠harness and discharges water throughâ the outlet â˘port; in âaddition, theâ pump can affect otherâ operationalâ subsystems such â˘as spin speed and cycle progression because incomplete drainage will⢠prevent âcertain âcycle âŁtransitions. Theâ pump⤠must also maintain a â¤seal âagainst theâ wet chamber to prevent leaks andâ protect âadjacent electronics and structural components.

Function and Role of âthe â˘Washer âŁDrain Pump in Frigidaire Laundry Appliances
The 137311900â Frigidaireâ Washer Pump is⣠an electric motor-driven âdrain⣠assembly that âremoves wash and rinse â˘water from the â¤tub during drain andâ spin âŁphases. It uses an⣠impeller housed in â¤a molded pump body to convert motor torque into hydraulic⤠flow; when theâ washer’s âcontrol board applies power the impeller forces water through the tub outlet and drain hose.Proper component replacement requires matching the pump’s mechanical mounting, electrical connector pinout, âimpeller orientation âand⣠hydraulic characteristics â(flow rate vs.head) âto the specific Frigidaire model to âmaintain designed drain performance and preventâ overloading the motor orâ creating back-pressure â¤in âŁthe plumbing.
- Common symptoms âof a failing pump:⤠no drain,slow âdrain,loud grinding or buzzing,or external leaks from the âpumpâ housing âŁor seals.
- Basic diagnostics: verify electrical⤠supply to theâ pump⣠during the⢠drain cycle,check⢠motor â˘winding continuity,inspectâ and clear foreign⢠debris from the impeller and filter,and⣠confirm the â˘impeller rotates freely âwhen the motor is unpowered.
- Compatibility âchecks: â¤confirm mountingâ flange, hose diameter, connector âtype and the pump’s hydraulicâ capacity match theâ appliance before âinstallation.

| Part | 137311900 Frigidaire washer Pump⤠– motor âand impeller âdrain assembly |
| function | Evacuates tub water during drain and spin âŁcycles by convertingâ motorâ rotation into â¤flow |
| Installation note | Verify electrical connector, mechanical fitand hydraulic capacity âfor the â¤specific washer model |
In service situations, technicians should isolate the pump electrically and mechanically before testing:⢠measure voltage⣠at⢠the connector â˘with the appliance â¤in a âdrain program, thenâ check motor continuity with â˘aâ multimeter and inspect theâ housing for trappedâ garments or hard debris. âA humming â¤motor âwithâ no âimpeller movement âŁtypically indicates a âseized rotor or jammed⤠foreign object; noisy bearings or persistentâ leaks warrant replacement rather than repair. Forâ appliance owners,â simple preventive maintenance-clearing the pump access âfilter and ensuring â˘drainâ hoses are â˘free of kinks-reduces âtheâ likelihood of premature â¤pump failure and helps maintain reliable operation.
How âthe â137311900 frigidaire Washer âPump âWorks: Motor, Impeller,â and drainageâ Circuit
The 137311900 frigidaire Washer â¤Pump âis a compact, sealed singleâphase electric motor assemblyâ that drivesâ aâ molded centrifugal impeller to âŁevacuate wash⤠water from the âtub through the discharge hose. The pump mounts to the washer base with a⤠direct âmechanical interface⢠and⤠a molded inlet that aligns⣠with â˘theâ tub drain; electrical power â¤is supplied from the âwasher control board via a âŁdrain⣠relay or triac so⣠the pump⢠runs only during drain and spin cycles. Internally the motor shaft âcarries a small plasticâ impeller inside a âvolute housing; a shaft seal âand integrated strainer protect the motor âfrom bulk âŁdebris and moisture. Correct⣠fitment requires matching the mechanical flange, electrical connector, âŁand discharge orientation supplied onâ compatible Frigidaire models, so the â¤137311900 unit is â¤used were OEM dimensional and electrical â¤specifications are required for reliable⤠installation.
Functional behavior â˘and⣠commonâ failure modes are straightforward to diagnose: the motor should spin freely and produce a steady flow out the âŁdischarge; ârestricted flow, reduced speedor complete failure âŁmost âfrequently⤠enough results âfrom impellerâ damage, debrisâ jams in the â¤voluteor âloss âof the startâ circuit in the motor. A⣠humming⤠motor with no â¤rotation â˘frequentlyâ indicates a seized impeller orâ a failed start winding while visible damage to vanes causes âŁcavitation â¤and poor drainage.⤠Technicians typically verify â¤continuity âand winding â¤resistance, inspect⢠the volute for foreign objects,â andâ confirm that â¤the control board is supplying mainsâ voltage during the⤠drain â¤command (e.g., ~120 V AC in North American machines)⤠before replacing â¤the pump. â˘Replacing the assembly restores correct hydraulic performance when the motor and impeller areâ the root âcause; âif symptoms âpersist, check â¤downstream hoses, clampsand check valves for â¤restriction or backflow.
- Key behaviors: â¤intermittent ârun âŁonly â¤during drain cycles, direct âmotor drive toâ centrifugal impeller, protected by⤠strainer and shaft â˘seal.
- Symptoms of failure: no⢠drain, slow drain, humming, loud âŁgrinding,â or leaking at pump housing.
- Practical â˘test: âmeasure windings, âŁvisually âinspect volute, confirm control voltage⢠before bench powering.

Common Failure Symptoms and Measurement-based â˘Diagnostics for Pump Faults
The drain pump on many â˘Frigidaire washers âis a⢠small centrifugal motor-impeller assembly that evacuates tub⢠water through âa âmolded housing; replacement units such as⤠the 137311900 âFrigidaire Washer Pump share the same electrical connector and mounting footprint used across several Frigidaire âtop-load models, â˘but verify harness type and mounting tabsâ before installing. Failure modes⤠are primarilyâ mechanical (blocked or broken impeller, worn bearings, sealâ failure) âor⤠electrical (openâ windings, short to ground, â¤or âloss of⢠drive voltage). Mechanical faultsâ typically âpresentâ as â˘reducedâ flow or grinding noises, while electricalâ faults produce no-spin or a constant hum; compatibility checks⢠should include âŁconnector pinout, mounting orientationand âŁdrain hose alignment to avoid⣠improper â˘installation that can mimic pumpâ failure.
Use measurement-based diagnostics âŁto separate mechanical from electrical causes:⤠confirm the controllerâ is commanding the pump â˘(measure expected drive âvoltage at âŁthe âpump connector during⢠a drain âŁcycle), then check the motor windings with a multimeter for continuity and insulation. A âworking pump will â¤show a low-resistanceâ winding and⤠no continuity â˘between windingâ and chassis ground; a completely open â¤winding indicatesâ a burned âmotor, while â¤a short-to-ground âŁindicates insulation âŁfailure. If voltage is present but the rotor⣠does not turn âŁand the â˘winding resistance is within ârange, âŁinspect the impeller and pump housing for âdebris or seized bearings. If the pumpâ draws excessive current when powered, that suggests mechanical bindingâ or âinternal friction â¤rather than an â¤electronic control âfault.
- No⤠drain or slow drain
- Continuous humming with âno ârotation
- Loud grinding, rattlingor vibration
- Water leakage from pump area or connector
- tripping the⢠household circuit or trippingâ washerâ motor protector
| Item | Description |
|---|---|
| Continuity | Low resistance âacross pumpâ motor leads âindicatesâ intactâ windings; open = failed winding. |
| Resistance | Typical⤠static winding resistance is approximately 10-50â Ί (varies by motor); consult âmodel â˘service data⢠for exactâ spec. |
| Applied voltage | Measureâ at connector⢠during drain⢠command; âtypically nearâ mains voltageâ (commonly ~120⤠VAC in North America). |
| Insulation | No âŁcontinuity between â¤winding and chassis ground; any continuity indicatesâ leakage and requires â¤replacement. |
| Current draw | Normal running current isâ modest; aâ marked increase âon⣠start or during â¤run implies mechanical binding⢠or defective bearings. |
Compatibility, Replacement Considerationsand step-by-Step Installation for the Pump
