Function âand Operational Role â¤of âŁthe â¤Washer Drain Pump Assembly
The primary mechanical ârole of the washer drain pump assembly⣠is⤠to⢠evacuateâ wash and rinse water from âŁthe tub and deliver itâ through the⣠drain hose âand plumbing under⤠command of⣠the machine âcontrol. theâ 137311900 Frigidaire Washer Pump is a âcompact motor-and-impeller unit âthat mounts beneath⤠the tub â˘and is energized during drain âŁand⢠spin cycles to âŁdevelopâ the âŁpressure â¤and flow required to overcome static lift and downstream restrictions.â Proper operation depends on secure hose connections,correct âelectrical matingâ to the control board,and âŁcorrectâ mounting orientation to minimize air ingestion âand vibration that reduce âŁhydraulic efficiency.
Understanding operational behaviour and â˘compatibility âŁhelpsâ diagnose failures andâ select the correct replacement. Technicians âverify applied voltage at the âŁpump during âa drain command, inspect the impeller and inlet for foreign objects, âŁand check for bearing noise or motor hum â˘that indicate mechanical obstruction or electrical distress. When replacing, match the â137311900 part to the washer model number,⢠confirm connector pinout andâ hose diameters, â¤and â¤ensure mounting tabs⤠align so the â˘pump â¤does not stress⤠hoses or the⤠control wiring; common field symptoms â¤include no drainage âŁwith no motor sound, continuous humming with⤠no flow, âintermittent operationand visible leakage âat â¤hose⢠or housing interfaces.
- Common symptoms: no drain, motorâ humming, slowâ drainage, leaks.
- Basic checks: verify control voltage atâ pump,⤠remove debris from inlet, inspect impeller âand âseals.
- Compatibility checks: confirm connector type, hose diameter, mounting orientation and modelâ fit.

Howâ the 137311900 Frigidaire Washer Pump Integrates with the Drive and Drain Systems
the⤠137311900 Frigidaire Washer Pump âis the⢠centrifugal component responsible for evacuating â¤tub water and linking â˘thatâ hydraulic âfunction âto the machine’s mechanicalâ drive and control âsystems. Mechanically, the pump â˘mounts âto âthe lower tub or chassis and âaccepts inlet⤠flow â¤from⢠theâ tub outlet; it is indeed driven by â˘the washer’s â˘main motorâ eitherâ through a molded coupling â˘orâ an integrated drive shaft⤠depending on the model.⤠Electrical integration is via the washer’s control â¤harness and cycle controller, which energizes the pump onyl during drain⤠and âspin sequences; proper integration requires matching the⣠pump’sâ mountingâ flange, inlet/outlet hose diametersand electricalâ connector to the existing assemblyâ so the impeller and seal orientation provide the expected flow and backflow âresistance within the drain plumbing.
Operational behavior⤠shows the pump âoperating in â˘coordination with âthe â¤driveâ system and water-level⣠sensingâ components: the controller enables the motor and pump in the correct sequenceand level switches or⢠pressure âsensors confirm⣠the â˘tub is empty⢠before spin speed is increased. In service or replacement situations,technicians should verify mechanical alignment,that âthe impeller spins⣠freely,and that the⤠drain hose⣠and lint âŁtrap are⢠clear;â failure modesâ that âindicate⢠integration problems include a humming⣠pump motor with no⢠flow (blocked impeller or failed coupling),intermittent draining (electrical or âcontrol-signal fault),and leaks atâ the mounting gasket. Practical integration checkpoints include:
- Mounting interface and gasket seating to prevent leaks and preserve alignment
- Electrical harness compatibility â¤and control⢠signal sequencing â¤for drain/spin cycles
- Drive coupling or shaft engagement ensuring the pump turns⤠when commanded
- Hose âdiameter and clampâ integrity to âprevent⤠backflow and âmaintain âflow rate
- Interactionâ with level sensors and lid/door interlocks â˘to prevent unsafe operation
| Item | Description |
|---|---|
| Mounting interface | Flange and âgasket that align pump⤠to tub outlet and âchassis mounting points |
| Drive coupling | Mechanical link (molded couplingâ or shaft) transmitting motor⣠rotation to the impeller |
| Electrical âconnector | control harness âconnection providing power and on/off sequencing⣠fromâ the washer controller |
Common âFailure Symptoms: Noise, Slow Drain, Leaksand Electrical Faults
The 137311900 Frigidaire Washer âPump is the centrifugal pump assembly that evacuates wash and â˘rinse water from the âŁtub; it couples âa â¤small⤠electric motor âtoâ an⤠impeller housed in a molded plasticâ body with inlet and outlet ports, â˘sealsand mounting lugs. Typical failure modes manifest⢠as audible âŁmechanical⢠noise (grinding, clacking,⤠or squeal), âŁreduced flow rate during the drain cycle, visibleâ leakage from the pump housing or shaft sealand electrical faults such as no-run or âintermittent operation. Proper replacement requires matching the pump’sâ mounting footprint, electrical connector type and polarity, â¤and impeller âŁorientation so that torque andâ flow characteristics âremain compatible with⤠the â˘washer’s plumbing andâ control sequence.
- Loud grinding âor rattling – usually aâ foreign object âat the âŁimpeller or damaged impeller âvanes; inspectâ the pump inlet⢠and â¤trap.
- Humming with â¤no rotation⤠– âoften indicates a seized rotor,failed start winding,or a jammed impeller.
- Slow drain – partial restriction in âthe â¤pump inlet, hoseor internal erosion/reduced impeller efficiency.
- Visible âleaks – degraded shaft seal, cracked⢠housing, âor improperly seated hose clamps.
- Intermittent⤠electrical faults or tripped breakers – shorted⢠windings,⢠internal moisture intrusionorâ control/cable âŁfaults.
Diagnosing âthese⢠symptoms begins⣠with a safe mechanical inspection: disconnect power, âŁremove the drain hose and check⣠for debrisand⢠visually inspect the pump⢠housing⣠and hose connections â¤for cracks or loose âclamps. for electrical troubleshooting, measure â˘lineâ voltage at the connector and perform a continuity/resistance check of the motor windings; a very low or open winding âŁreading indicates motor failure, âwhile a normal winding resistance with no rotation suggests mechanical seizure.â Practical examples: a humming soundâ with normal line voltageâ and high⤠current draw âŁpoints to a⤠locked rotor; a normal-sounding motor withâ slow drainage points to partial blockage in â˘the drain âŁpathâ rather than an âelectrical fault. âDocument mounting and connector detailsâ before replacing âthe pump âto ensure the replacement part provides equivalent âŁflow â¤andâ electrical characteristics.
