Function â˘and Role of the Washer Drain pumpâ Assembly in Water âExtraction and Drainage
Theâ pump assembly converts electrical energy into â˘hydraulic flow by driving an impeller inside a sealed housing to evacuateâ wash and rinse water from the tub and deliverâ it âto the household drain.The 137311900 Frigidaire âWasherâ Pump integrates a small⢠AC âmotor, impeller, â˘and inlet/outlet â˘passages; its⣠operation is⤠synchronized with the âwasher controller so the pump runs during drain âand spin phases and stops once the waterâ level has dropped âŁbelow theâ pressureâ switchâ or âsensor threshold. Technically, the assembly must provide â˘sufficient⢠flow and head⢠to overcome the drain hose elevation and⢠any air gap,⤠tolerate particulate loads that pass through the tub,â and maintain electrical insulation and thermal protection for the motor in a damp environment.
- Primary behaviors: motor-drivenâ impeller flow, intermittentâ runtime controlled by âwater-level sensorsand âpossible reverse-flow âprevention via hose routing or integrated check⤠features.
- Common âsymptoms âŁof failure: standing water after drain cycle,⢠humming or grinding noises from the pump, â¤reducedâ flow ârate,⣠or visible leaks at â˘the housingâ or hose connections.
For serviceability and compatibility, technicians should verify mounting points, â˘hose barbâ sizesand electrical â¤connector type before installing a replacement pump; many pumps share form factors but differ in connectorâ orientation or⢠gasket interfaces.â Troubleshooting typically involves measuring line voltage at the pump â˘connector, checking motor âwinding continuity with an âohmmeter, inspecting and âclearing debris from the impeller and trap, âand confirming that the drain hoseâ is free of⣠kinks and installed with an âanti-siphon⣠loop. Replace the pump if the motor â˘draws abnormally â¤high current, if the⣠impeller is eroded orâ brokenor if the housingâ exhibits cracks âthat cause⢠leaks; after installation, run a drain test to confirm â¤correct flowâ and⢠absence of air âŁleaks.

How the 137311900 Frigidaire Washer pump⣠Works inside the Appliance: â¤Motor, âImpellerand valve â˘Integration
The 137311900â Frigidaire Washer Pump is a compact pump assembly that combines a sealed electric âmotor, a âmolded centrifugal â¤impeller,â and aâ molded valve or valve seat within a single housing to manageâ drain and ârecirculation flows. Theâ electric drive is a lowâvoltage (line powered) sealed⤠motor â˘designed for intermittent duty; it mounts directly to theâ pump housing⣠so torque is delivered to⣠the impeller with minimalâ coupling⤠losses. The impeller is typically a molded plastic centrifugal⣠type⣠that acceleratesâ water into the discharge port,while the molded valve geometry âŁand mating hose connections control flow direction andâ reduce backflow into the⤠tub. Proper mechanical fit – âmatching mounting tabs, electrical âconnector typeand hose⢠diameter – is required for direct âcompatibility with Frigidaire âwasher âmodels â˘that specify this part number.
In âŁpractice, the assembly’s âŁbehavior is diagnostic: a humming motor with⤠no flow usually indicates an impeller jammed by âŁdebrisâ or a â˘seized â¤bearing, âŁwhile no âhumâ and no flowâ points to an electrical âŁopen or failed motor. Leaks around the housing or at the outlet⤠suggest seal or âhousing damage rather than an electrical⢠fault. Technicians shouldâ inspect the impeller forâ foreign⣠objects,verify hose and â˘filter cleanliness,and confirm connector pin continuity before âreplacing âthe whole unit; when⤠replacing,confirm the pump orientation and hose routing match âŁthe original to preserve check-valve function and avoid siphoning. Forâ bench âchecks, âconfirm âthe⢠impeller turns freelyâ by hand and⢠compare â¤mounting/electrical details against the service sheet for the âspecific washer âmodel.
- Common symptoms: âhumming⢠without drainage, intermittent âŁdraining, leakage at housing or hoseand unusual ânoise from the washer âduring âdrain.
- Quick âchecks: manual impeller rotation,visual inspection for âforeign debris,continuity check at the âpump connector,and verification of hose âŁand clamp condition.
- Compatibility checks: confirm electrical connector type, mounting flange shape, âand discharge hose diameter before âordering or installing the pump.
| Item | Description |
|---|---|
| Motor | Sealed, singleâspeed electric motor mounted to â˘the pump housing; drives the impeller and is designed for intermittent duty with specific connector and mounting features. |
| Impeller | Molded centrifugal impeller that âmoves âwater from the tub to the discharge; susceptible to jamming by âsmall items andâ lint buildup. |
| Valve⢠/ Seat | Molded passage or integrated valve element that reduces backflow and helps route discharge; requires⤠correct hose⣠routing and orientation to function as intended. |
Common Failure âSymptoms and âObservable⣠Electrical/Mechanical Faults of the pump
The 137311900 Frigidaire Washerâ Pump is responsible for evacuatingâ wash water from the âŁtub during âŁdrain⢠and spin cyclesand common failure symptomsâ are usually evident at the point⣠of use. Typical behaviors⤠that⣠indicate a failing pumpâ include failure to drain,greatly reduced flowâ rate,loud grinding âor rattling noises âduring operation,and visible leakage at the pump housing⢠or hose âconnections.Compatibility with the washer’s control⤠and harness means â¤that the pump âshould receive line âvoltage when the control calls⢠for drain; if the control is commanding but the pump âshows no activity, the fault will be either electrical⤠(wiring, switchor⢠motor winding) or mechanical (impeller damage,â foreign objector⤠seized shaft).
Electrical faults present⣠as âopen â¤windings, short-to-ground conditions, intermittent âŁcontacts,â or⣠thermal âŁprotection â˘trips and âare diagnosed⣠with a multimeter: check for supply âŁvoltage atâ theâ pump harness during a drain command and verify motor âwinding continuity and insulation to chassis. mechanical faults are visible⢠on inspection – brokenâ or eroded impeller vanes, trapped debris in the inlet, corroded housingsor worn bearings will cause noise, reduced pumping efficiencyorâ rotor seizure. For example, a pump âthat hums⤠but does not rotate⤠often has âŁa jammed impeller or collapsed drainâ hose; if âthe multimeter showsâ properâ supply but infinite⤠winding resistance, theâ motor winding is open and the pump requires replacement rather than repair.
- No drain â˘or slow drain: pump not ârunning, clogged inletor collapsed/blocked drain hose.
- Humming âwith no water movement: âŁjammed impeller,⢠seized shaft, âŁor foreign object lodged in âthe âpump.
- Loud grinding or rattling: â˘damaged impeller, loose debrisor failed bearings.
- Leak at housing or â˘hose: cracked housing, failed seal, âor loose hose/clamp.
- Tripping breaker or burning smell: shorted winding, motor overheatingor⢠internal electrical⢠fault.
| Item | Description |
|---|---|
| Supply check | Measure voltageâ at pumpâ connector âduring drain command; presence of line voltage⤠isolates the fault âto the pump or wiring. |
| Motorâ continuity | Low but⣠finite resistance between motor leads indicates intact winding; infinite resistance indicates openâ winding. |
| Mechanical inspection | Remove suction cover to⤠inspect impeller, shaftâ playand foreign debris; check forâ cracks in housing⤠or evidence of⢠water ingress atâ motor. |
