Function and Role of the⤠Washer Drainâ Pump in Extraction andâ Drain⢠Control
The 137311900 Frigidaire Washerâ Pump performs the âprimary hydromechanical task of evacuating wash âand rinse water⢠from the tub and â˘maintaining controlled â˘flow during the extraction phase. Whenâ the washer enters a drain or spin cycle the pump is driven by its âmotor assembly âŁto create sufficient flow through the drain hose⢠soâ the âŁcontrol â˘board can monitor tub conditions and âŁallow high-speedâ spin without residual water causing imbalance.â The⣠pump housing⤠guides flow past⢠theâ impeller and into the âoutlet;â integratedâ features such as a molded⢠volute,⤠trap chamberor aâ simple check valve⢠help âŁprevent backflow and reduce âthe âŁchance of residual water remaining in the tub between cycles.
Technically,the pump⣠behaves as a flow device coupled â¤to the machine control:⢠it runs untilâ the âpressure or âwater level signals that â¤the tub is empty or until a timed drain â˘interval⢠completes. Compatibility considerations for replacement âŁinclude mounting flange âgeometry, electrical connector pinoutand the pump’s hydraulic âorientation relative to theâ tub and drain hoseâ – a mismatched âorientation can reduce âflow rate or create⤠air â˘pockets that impair extraction.â Typical field symptoms âthat indicate⤠the pump needs inspection or replacement âinclude reduced⣠orâ no â¤water â¤discharge, a loud grinding⤠orâ humming noise âduring operation, visible leaks at the housing,â and⤠intermittent âoperation caused by electrical âfaults or â¤clogged debris.Practical troubleshooting often involves checking â˘the outlet âhose for obstructions,â verifying supply â˘voltage at theâ pump connectorand⢠inspecting â¤the impeller for âdamage or foreign objects.
- No âdischarge orâ slow drain
- Humming motor with no impeller⢠movement
- Leaking at housing⤠seams âor â˘seals
- Intermittent âŁoperation or thermal cutoff trips

How âthe 137311900 Frigidaire Washer Pump Operates Within the â¤Washer’s Drainage and âControl System
The 137311900 âFrigidaire âWasher⤠Pump âŁsits at the âlow point â˘of the washer tub and evacuates wash â¤and rinseâ water through the drain hose during⢠the⣠washer’s âŁdrain cycle. â¤The pump is a compact electric unit with â˘an impeller-driven⤠chamber;⤠the washer’s main⣠control board⤠energizes the pump âŁvia a relay â˘or triac to apply line powerâ for â¤the duration of the drain command. â˘In normal operation the pump must âseal to â˘the tub outlet,tolerate small debris,and âmaintain sufficient head to push water through theâ home’sâ plumbing âtrap; failures that allow âair leaks,impellerâ damage,or motorâ brush wear will reduce flow or cause complete⤠loss of drainage. Such âŁas, a pump that humsâ without moving water often indicates an âŁobstructed impeller or a⢠downstream restriction such as a kinked âhose, whereas a pump that does not energize at all suggests âa âŁcontrol or wiring fault rather than a hydraulic problem.
Technicians⤠and appliance owners should âtreat the 137311900 â˘Frigidaire Washer Pumpâ as â¤both an electrical load⤠and a hydraulic â¤component: verify â˘the control board sends the expected âŁdrive signal before replacing the pump,⣠and confirm âphysical compatibility of mounting tabs, inlet/outlet diametersand electrical connector types whenâ sourcing replacements. Common practical diagnostics include â˘listening for motor noise during a âdrain command, checking for resistance/continuity across the pump motor leadsand visually inspecting the⢠impeller housingâ for debris or cracks. Field replacement examples: â˘if the âpump⢠spins when bench powered but fails to clear standing water in the machine, inspect the drain hose and trap; if the pump receives no voltage, trace the â˘wiring âŁand test the control relay or lid/door interlocks that âcan inhibit âthe drain⤠command.
- Primary function: âevacuates tub water during drain and pump-outâ phases.
- Control interface: driven by washer control âŁboard via relay/drive circuit.
- Typical â˘failure modes: impeller clogging,⣠motor brushâ wear, cracked housingor electrical connector faults.
- Diagnostic⢠cues: humming with no âŁflow,⢠intermittent âŁoperation, leaks âŁat pump housing â˘or⤠couplings.

Common Failure Modes and Diagnostic Symptoms of Frigidaire Washer Pumps
The 137311900 Frigidaire Washer Pump is âthe drain assembly that evacuates wash â¤water from the tub; it combines a â˘smallâ electric â¤motor, âan⢠injectedâmolded pump housing,⣠an âŁimpeller and shaft âseals. Common mechanical âfailure modes include impeller blockage or entanglementâ with fabric and debris, shaft/bearing wearâ that âcauses âthe rotor to sieze or run eccentricallyand seal failure that produces external âŁleakage and shorted windings. Electrical âŁfailures present as⣠open or shorted motor windings, intermittent connector âfaultsor broken leads; because⤠mounting flanges and electrical harnessesâ can vary between⢠model series,â technicians shouldâ verify connector pinout,â mounting orientation and â¤seal type before â˘assuming interchangeability⤠with other Frigidaire pumps.
Diagnosingâ pump âfaults âfocuses onâ separating â˘mechanical from electrical causes:⢠visuallyâ inspect⢠and manually rotate the âimpeller âto detect binding or â¤foreign objects, listen for a steadyâ motor hum â˘versus an irregular knocking or grindingand âmeasure âcontinuity across the motor âand the presence of driveâ voltage⤠at the pump connector âduring theâ drain cycle. â˘Such as, if the control âsuppliesâ lineâ voltage⤠to the pump⤠but the impeller does not turn, âthe âfailure is usually mechanicalâ (blocked impeller, seized bearings or⤠broken shaft);â if⤠there is no drive voltage, investigate⤠the âcontrol board, lid/door switch⣠and wiring⤠harness. Routine practical checks include clearing the â˘trap/tub sealâ area,⢠inspecting hoses for â˘kinksâ and verifying that replacement pumps match the electrical connector⣠and mounting geometry for the specific Frigidaire âmodel.
- No â¤drainâ and no noise: likely open winding, faulty connector,â or no control output-check âcontinuityâ and⤠control voltage.
- Hums but â¤won’tâ pump: impeller jammed,seized bearings,or collapsed impeller-inspect and rotateâ impeller manually.
- Intermittent âoperation: â loose connector, intermittentâ wiring breakor failing motor brushes/electronics-wobble connectors and backprobe âduring âcycle.
- Water leaking at⣠pump: ruptured â˘housing or failed shaft seal-replace pump assembly to ârestore pressure integrity.
