Function and â˘Role â˘of the Washer âDrain Pump in Frigidaire laundry Systems
The 137311900 Frigidaire Washer Pump is an electromechanical drain âpump assembly that evacuates wash water from theâ tub to the household drain. The pump uses a âsmall motor to drive â˘a molded impeller that⤠forces water â¤through the drain hose;⣠the washer’s main control board âsupplies power to the pump only⣠during drain and certain diagnostic cycles. In ânormalâ operation the âŁpump âwill run âfor âdefined drain intervals,⣠stop when the water âlevel sensor indicates empty or when the control logic completes⣠a drain stepand is designed with thermal âprotection and âmolded â˘mounts â˘to withstand⣠vibration and âintermittentâ runs typical of âlaundry cycles.
- Water fails to evacuate or slow draining
- Pump hums âbut impeller does not turn (possible jam)
- Continuous running or intermittent runs without completing drain
- Visible leakage at pump housing or â˘hose connections
| Item | Description |
|---|---|
| Electrical supply | Nominal 120 VAC on standardâ US models; driven by⢠washer control board âduring drain |
| Mount/connector | Snap-in â˘or bracket mount with⣠two-pin â¤power connector; verify harness âcompatibility⢠before replacement |
| Mechanicalâ features | Molded plastic impeller⢠and sealed⤠housing; designed to âpass small debris but susceptible to jamming by coins,⤠buttonsand âŁfibrous lint |
For service, inspect the â˘pump â¤impeller for obstructions and verify voltage is present at âthe â˘pump terminals during âŁa drain command; âŁif supply voltage appears andâ the impeller is free⤠but the motor does not turn, replacement of the assembly is appropriate. When fitting a replacement⣠suchâ as the 137311900 Frigidaireâ Washerâ Pump, â˘confirm matching mounting points, connector⢠type,â and âŁdrain⤠hose orientation; also check adjacent components (drain hose, tub outlet, â˘and water level sensing) because â˘restrictions or control faultsâ can mimic pump failure. Practical field checks include âspinning the impeller by hand to confirm freedom of movement, checking for leaks at â¤the gasketand monitoring current draw or control board output to isolate electrical⣠versus mechanical faults.
How the 137311900 Frigidaire â˘Washer Pump Works Inside the âAppliance: Motor, â˘impellerand Seal Dynamics
The 137311900 Frigidaire⤠Washer Pump uses a compact â¤singleâspeed electric motor âdirectly coupled to âa âmolded centrifugal impeller to evacuate wash water through â˘the drain path. The motor⢠produces rotational torque at a fixed speed,and theâ impeller⢠converts that rotationâ into radial flow; this arrangement yields reliable flow rates for standard drain cycles while âkeeping the assembly compact and serviceable.A mechanical shaft seal and rubber elastomericâ components isolate the motor windings from⢠the pumped water-this âseal interface â¤is â˘the primary water-retention element and is designed to âtolerate the typical particulate load âfound âin householdâ laundry applications. The pump isâ supplied as an OEM replacement for matching Frigidaire models and is engineered to mate with the factory housing, â¤drain⣠hoseand âelectrical connector patterns used onâ those machines.
The operational â˘behavior becomes apparent during diagnostics: âŁa worn or clogged ⣠impeller âreduces⤠flowâ and causes âthe motor to drawâ higher âcurrent and hum, while a compromised seal typically presents as external âleaks, corrosion on⤠the motor bodyor âsudden â¤motor failure after water intrusion. Practical troubleshooting steps for technicians include checking for trapped debris at the impeller inlet,measuring⣠motor resistance and current during a⣠drain cycle,and âverifying free impeller rotation by hand withâ power removed. â¤Common field symptoms and inspection checkpoints include:
- Humming â¤without flow – suggests jammed impeller or high⤠current draw.
- Slow or âincomplete drainage – indicates partial blockage or impeller wear.
- Visible leaks or rust at the pump âbody⢠– points â¤to seal failure.
- Intermittent operation – may be electrical⤠connector or motor winding⢠issues.
| Item | Description |
|---|---|
| motor | Compact singleâspeed electric motor, directâcoupled to impeller for drain cycles. |
| Impeller | Molded centrifugal vanes (typically plastic)⤠that produceâ radial⤠flow; sensitive to lint andâ debris. |
| Seal | Mechanical elastomer/faceâ seal at the shaft to prevent waterâ ingress â˘into motor cavity. |
Commonâ Failure Symptoms â˘and Performanceâ Indicators of the Pump Assembly
The 137311900 Frigidaire Washer Pump is the drain assembly âresponsible for evacuating wash water at âthe end of fill and during spin cycles; it combines â˘a⤠small motor, impeller andâ housing tailored to the â¤washer’s plumbing and electrical interface. Functionally, the pump must provide a sudden high-flow discharge â¤while resisting brief dry-run and debrisâ exposure. Common mechanical and electrical âbehaviors that indicate degradation include increased rotational friction (bearing âŁor âdebris contact), loss⢠of⣠hydraulic performance⤠(wornâ or â¤broken impeller vanes), water ingress intoâ the motor housing (failed seals)and intermittent electrical faults âdue âŁto winding damage or connector corrosion. These failure modes â¤change measurable outputs – reduced flow rate, elevated motorâ currentor abnormal acoustic signatures – and can also present as symptoms that mimic control board or door-interlock faults on compatible Frigidaire models.
- Slow or incomplete drain resulting â˘in standing water or â¤failed spin.
- Loud grinding, rattlingor â˘high-pitched whine during the drain cycle.
- Humming⣠motor with no water movement (motor energized but impeller stalled).
- Visible leakage at the pump housing or electrical connector.
- Tripped circuit protection or blown fuses â¤correlated to pump activation.
Technically useful diagnostics include visual inspection for âforeign objects in the pump trap, measuring continuity and insulation resistance of⢠the pump motor windingsand verifying⣠that the â˘correct supply voltage is present atâ theâ pump connectorâ during the drain phase. If voltage â˘isâ presentâ and the impeller does not rotate â¤freely,â the fault is mechanical (jammed debris,â seized bearings or broken impeller) or the motor has internal⤠damage; if no voltage is supplied, the⤠issue is upstream âŁ(control,â door/lid switch, harness). Use a clamp meter to compare inrush andâ running current against the service specification for the washer⤠model; abnormallyâ highâ running current⢠with slow rotation indicates mechanical binding, while an open winding or zero currentâ indicates electrical failure. Confirm compatibility âand âfitment of replacement pumps against⢠the appliance model number before⣠installation,and clear evidence such asâ persistentâ leaks or insulation failure generally warrants pump replacement rather than repair.
| Item | Description |
|---|---|
| Slow drain | Partial â˘clog, worn impelleror restriction in discharge hose âŁreducingâ flow rate |
| Humming without flow | Motor energized but âimpeller âstalled due to jam, seized bearings, â˘or broken coupling |
| Leakage | Damaged housing seal or⤠cracks permitting water ingress and potential â¤electrical damage |
