Function and role of the Washer Pump: Hydraulic,Electrical,and Control Responsibilities
The 137311900 Frigidaire washer Pump is⣠an integrated motor-and-impeller assembly that handles the hydraulic task of removing â¤wash and rinse water⤠from the tub and maintaining correct⣠flow during drain and spin phases. The pump’s volute and impeller generate the âŁpressure required to âovercome discharge hose head and any in-line check valves; the housing often incorporates a molded inlet/outlet,mounting flange,and a⣠one-way âvalve to prevent backflow into âŁthe tub during spin. Electrically, the âunit contains a small singleâphase motor with internal thermal protection and a rotor/stator arrangement; the washer’s âmain control board supplies mains-level power to the pump only âduring the programmed drain or recirculation stepsâ and may monitor âpump current as a crude feedback signalâ indicating a jam or load condition. Typical operational behaviors⢠technicians â¤observe are âa clean â¤start with steady motor⣠tone, reduced flow âor noise when the impeller is obstructedand an increased current draw if bearings or the impeller binding develop mechanical resistance.
- primary responsibilities: move water from tub to drain, break suction during spinand prevent backflow.
- Electrical interface: powered by the washer controller with on/off mains voltage; may show current surgeâ when stalled.
- Common symptoms of malfunction: no drain, humming without rotation, intermittent drainingor leaks at the pump housing.
- Compatibility considerations: mounting flange, hose diameters, electrical connector typeand presence âof anâ integrated check âvalve.
Forâ practical diagnosis and replacement, verify that âthe control board is â¤commanding the pumpâ (measure for mains voltage at âthe pump connector during the drain cycle) before condemningâ the pump; if voltage is present and the motor does ânot turn, inspect the âimpeller for debris and⤠check rotor freedom by hand, âthen measure winding⣠continuity âŁto âthe motor terminals. When replacing the pump, confirm mechanical fit (flange and hose orientation), connector pinoutandâ that any included gaskets or âcheck valves match the appliance’s requirements-bench testing âŁa suspected unit with the correct supply voltage is useful but must be performed with safety precautions. The âtable below summarizes key technical⢠references useful⤠during service and procurement.

How the 137311900⤠Frigidaire Washer Pump âWorks Inside the Appliance
The 137311900 Frigidaire Washer Pump is a compact â˘electromechanical drain assembly that convertsâ electrical â¤power into⤠rotational motion to âexpel⢠wash water from the tub through â˘the drain hose. Internally, a â¤small electricâ motor drives a molded impeller âŁinside a sealed plastic housing; water entering from the tub is accelerated by the impeller âvanes âand directed out the discharge port. The pump is energized by the washer control board during drain and spin âcyclesand may include a simple thermal protection or brush-type motor construction depending on the model. Flow behavior depends on impeller integrity, inlet/outlet clearancesand any âintegrated check-valve âŁor trap â¤geometry that prevents â¤backflow into the tub during spin extraction.
For service and compatibility considerations, the pump is a direct-fit assembly on specific Frigidaire chassis and⣠shoudl be matched to the machine’s mounting points, hose diametersand⢠electrical connector style. Typical field diagnostics include verifying the control⤠sends voltage to the pump during a âdrain command (measure voltage at the pump terminals), checking for continuity across the motor windings,⣠and inspecting⢠the impeller âcavity⣠for lint, coins, âor sock material that can jam or abrade the impeller. Practical failure modes are mechanical⢠seizure (foreign object or bearing wear),electrical open windings or intermittent brushes,and housing cracks that cause leaks; replacing the pump assembly is commonly faster than in-place motor repair for these units.
- No âdrain or slow drain: possible impeller â˘damage, clogs,â or electrical failure
- Humming without water flow: motor energized but impeller jammed
- Leaking at housing seam or port:â cracked pump body or â¤failed seal
- Fitment⢠checks: verify mounting⣠tabs, hose IDand connector pinout before replacement
| Item | Description |

Common âFailure Symptoms and Measurable Diagnostic Indicators
The 137311900 Frigidaire Washer Pump is a compact, motor-driven⢠centrifugal pump that evacuates âwashâ and rinse⣠water from the tub through the drain hose. It is indeed typically a⢠direct-replacement assembly that includes the impeller,motor,and â˘sealing âinterface; compatibility depends on mounting flange âgeometry,electrical connector type,and shaft orientation,so technicians should confirm â¤part fitment against the washer’s model and the OEM service manual before installation. Functionally, failures arise from three primary mechanical/electrical causes: hydraulic⤠blockage âŁ(foreign objects or lint limiting impeller motion), mechanical wear (bearing orâ impeller degradation producing vibrationâ or contact)and âŁmotor/electrical faults (open windings, shorted turnsor connector/cable faults). observing pump behavior â¤during a drain cycle-start delay, persistent humming, irregularâ flowor visible⢠leak-helps⤠isolate whether the problem âis hydraulic, mechanicalor electrical in nature.
- Failure to drain⤠or very slow draining
- Hummingâ with â˘no impeller rotation
- Intermittent operation or tripping the circuit
- Visible leakage or⤠oil/contamination at the seal
| Item | Description |
|---|---|
| No drain / reducedâ flow | Measure harness voltage during drain; inspect and clear impeller and inlet; perform â¤a bucket âflow test⢠to quantify liters per minute. |
| Humming / no rotation | Check motor winding continuity andâ insulation with a multimeter; measure running current for elevatedâ draw indicative of jam or bearing seizure. |
| leakage / contamination | Visually inspect the seal⤠area and mounting gasket; â˘replace the pump assembly âŁif seals⣠are breached or if bearings are contaminated by fluid. |
To produce⤠reliable diagnostics,⣠record measurable indicators and compare them to the machine’s service specifications: supply voltage at the pump connector during âthe⤠drain command, steady-state running current, motor⢠winding resistance and insulation⢠resistanceand volumetric flow over a timed interval.For example, if â˘mains voltage is present at the connector âbut theâ motor draws near-zero current and produces only a faint⤠hum, the likely issues are an internal winding openâ or a broken rotor coupling-confirm by measuring winding âresistance and testing â¤for rotor freedom â¤by hand. Conversely,⤠high current with little or⢠no rotation usually indicates mechanical seizure or âŁa foreign âobject; in that case a visual impeller inspection and manual rotation â¤test are faster and more conclusive than replacing parts without measurement.
Compatibility, âReplacement Considerationsand Step-by-Step Installation Guidelines
Theâ 137311900 frigidaire âWasher Pump is an electrically driven drain pump that evacuates wash and rinse âwater from the tub using a âmolded impeller âŁand a sealed motor assembly. âIn service, failure modes are typically mechanical (impeller âŁdamage, âŁforeign-object blockage), electrical âŁ(winding open or shorted, worn brushes ifâ applicable)or hydraulic (collapsed or mismatched discharge hose,⣠failed check valve). Compatibility depends on three physical interfaces: âŁthe mounting flange and tab pattern,the electricalâ connectorâ pinout and voltage,and the discharge hose diameter and orientation. â˘Before replacing, verify that the replacement pump matches the â˘washer model’s âmounting â˘geometry and connectorâ type ârather than relying⢠solely on part-number âlists, as some aftermarketâ pumps alter connector orientation or âinclude integrated valvesâ that change hose routing and clearance â¤requirements.
| item | Description |
|---|---|
| Voltage | Typically 120 VAC âŁ(verify service label) |
| Mounting | Flange/tabs specific to Frigidaire models |
| Connector | 2-3 pin sealed harness (confirm pinout) |
| Hose size | Standard 5/8″-3/4″ discharge hose (measure⤠existing hose) |
Replacement âand installation actions should prioritize safety and preservation of seals.First, â disconnect power, then drain any residual water intoâ a bucket andâ disconnect the âwasher â¤from water sources.â Access âis usually via the front panel or lower access panel; take note of hose routing, mounting tab orientationand the position of âany spring clamps or worm clamps. Typical âŁinstallation sequence: remove electrical â˘connector and discharge hose, unfasten mounting clips, transfer any ârubber grommet or gasket â¤to the new âpump if serviceable (prefer replacing gaskets), fit âthe pump into the housing âensuring correct impeller orientation and tab engagement, reinstall âclampsâ and connector, then restore⤠power and run a short drain cycle to confirm proper operation and absence of leaks. If the âpump does ânot run or is noisy after installation, check harnessâ continuity, verify correct voltage at the connector, âand inspect for impeller contact with the housing or foreign-object debris.
Q&A
What is Frigidaire part 137311900 and which washers does it âfit?

Fit varies by⣠model year⢠and configuration – always verify fit by â¤comparing the washer’s model number⢠(from the tag on the â˘cabinet or behind the lid) with the part crossâreference from frigidaire or your parts supplier before ordering.
What are common symptoms â¤that âthe 137311900 â¤pump is failing?
typical signs include the washer not draining â˘or very slow draining,water remaining in the tub after the cycle,the pump motor humming⢠but not spinning,unusually loud grinding â¤or rattling noises during drain,and visible leaks around the pumpâ or its hose connections. Some control boards may also display a drain⤠or communication error code.
How can I â¤check whether the pump is⢠the cause â¤of a noâdrain problem?
First disconnect⤠power and remove standing water (use a bucket/towels). Inspect and remove clogs from the pump inlet, hose and trap. With power off, check âfor free rotation of the impeller by hand andâ inspect for debris. Use a multimeter to check pump motor⢠windings for continuity (compare to service manual spec) -⤠no continuity usually means a âbad motor. To confirmâ electrically, âwith the washer âpowered and in drain mode, âcarefully verify⤠the pump receives âline voltage at âits connector (only if you are experienced and pleasant testing live circuits). If âthe â¤pump gets voltage â¤but does not run, the pump⣠is faulty; if it âŁgets no voltage, â˘troubleshoot the timer, control board, lid switch or drain solenoid first.
Canâ I repair the pump or should I replace it?
If âthe problem is a clog or small foreign object you can usually clear and reuse the pump. If the motor is burned, bearings are noisy/worn, the impeller is damagedor there is an internal âŁleak,â replacement is⤠the appropriate and costâeffective fix. The pumpâ assembliesâ are generally âŁsold as complete units and are inexpensive compared⤠with the labor and uncertainty âof motor repair.
How do I remove and â˘replaceâ the 137311900 pump (basic procedure)?
General steps: unplug⢠the washer and turn â˘off water.â Drain any remaining water from⢠the tub and hoses. Access the pump by removing the lowerâ front or back access panel (depends on model).
