137311900 Frigidaire Washer Pump is an electromechanical drain pump assembly designed to remove water from the washer tub during drain and spin cycles.The component typically consists of a small electric motor coupled to a plastic or metal impeller housed in a pump body, with electrical connectors and mechanical mounting features that allow it to be integrated into a washing machine chassis.
Within the appliance, the pump interfaces directly with the tub, drain hose, pump housing, and the washer’s control and sensing systems.It activates during specific portions of the wash program to create fluid flow from the tub to the household drain, and it is coordinated with the water inlet valves, pressure switch or electronic water-level sensing, and the control board or timer that supplies power. Mechanically and hydraulically, the pump must maintain sufficient flow and pressure to evacuate water quickly while sealing interfaces to prevent leaks; electrically, it must respond to control signals and withstand typical washer supply conditions and load currents.
In this article readers will find a technical overview of the pump’s function and internal construction, guidance on model and connector compatibility, common failure symptoms and diagnostic steps for use by technicians and owners, basic troubleshooting procedures to isolate electrical, mechanical, and hydraulic faults, and practical considerations for safe replacement and reassembly (including mounting, sealing, and post‑installation testing). The information is presented to support accurate fault identification and informed replacement decisions rather than promotional recommendations.

Function and Role of the Washer Pump in Frigidaire Laundry Systems
The 137311900 Frigidaire Washer Pump is an electromechanical drain pump assembly that evacuates wash and rinse water from the tub by converting motor rotation into axial flow through an impeller and discharge port. In operation the washer’s control board energizes the pump during drain and spin cycles; the impeller forces water through the pump housing and out the drain hose while integrated strainers or screens capture larger debris. The assembly typically incorporates a molded mounting flange and electrical connector that mate to the washer’s sump and wiring harness, and many North American Frigidaire machines use a 120 VAC single‑phase motor with thermal overload protection, so installation requires matching the pump’s electrical and mechanical interface to the washer model number to ensure proper sealing and orientation of the discharge outlet.
Failures of this pump fall into two technical categories: mechanical (impeller jam, worn bearings, leaks) and electrical (open windings, shorted motor, intermittent contacts). Technicians troubleshooting a non‑draining washer should inspect the pump housing for foreign objects, verify continuity of the motor windings with a multimeter, and observe whether the pump motor receives voltage during a commanded drain cycle; a bench test with controlled voltage can confirm rotor freedom but should be done safely. When replacing the pump, confirm compatibility with the washer’s model number and connectors, replace any worn gaskets or clamps to prevent leaks, and note that symptoms such as humming without flow, noisy bearings, or water remaining in the tub after a spin cycle typically indicate the pump rather than the control board.
- No drain and humming: likely impeller jam or seized bearings.
- Loud grinding or rumbling: mechanical wear or foreign object contact.
- Intermittent operation: electrical connector/cable fault or motor overheating.
- Leakage at pump housing: failed seal or cracked housing-replace gasket and pump body as needed.

How the 137311900 Frigidaire washer Pump Operates: Internal Components, Motor, and electrical Interface
The 137311900 Frigidaire washer pump is a compact drain pump assembly that converts electrical energy into a centrifugal flow for evacuating wash water. Internally it consists of a molded housing and impeller, a short shaft supported by bearings, sealing elements to prevent water ingress into the motor, and the electric motor stator/rotor assembly. The pump’s hydraulic path directs tub water through the impeller and out the drain hose while preventing backflow with an integrated check or flap in many assemblies. In practice this means common service symptoms – slow draining, a loud grinding or squealing noise, or leakage – often point to a clogged or damaged impeller, worn bearings, or a compromised seal rather than an electronic control fault; technicians routinely find foreign objects (coins, lint, bra-wire) lodged in the impeller during diagnostics and replacement.
Electrically,the unit is designed to interface directly with the washer’s control system using a simple two- or three-conductor connector and is switched by the machine’s relay,timer,or triac when a drain phase is commanded. The motor is intended for household mains (typically 120 V AC in North American appliances) and may include thermal protection or a start winding depending on the specific pump batch; always verify voltage and connector pinout against the washer’s wiring diagram before installation. Troubleshooting steps that separate electrical from mechanical failure include measuring applied voltage at the pump terminals during a drain cycle, checking motor winding continuity with an ohmmeter, and manually turning the impeller (with power removed) to verify it rotates freely. If correct line voltage is present under load and the rotor does not turn, replacement of the 137311900 Frigidaire Washer Pump assembly is usually required; if no voltage is present, the fault is upstream in the control or wiring harness.
- Impeller: Centrifugal blade that moves water.
- Motor: Compact mains-driven motor coupled directly to the impeller shaft.
- Seals and bearings: Prevent water ingress and allow free rotation.
- Electrical connector: Two- or three-pin connector matched to the washer harness.
- Mounting/interface: Housing flange and hose outlet that match specific Frigidaire chassis points.

Common failure Symptoms and Diagnostic Indicators of Pump Malfunction
the 137311900 Frigidaire Washer Pump is the electromechanical assembly responsible for evacuating wash and rinse water from the tub to the household drain. technically it consists of a small fractional‑horsepower motor, an impeller enclosed in a molded housing with inlet and outlet passages, and seals/couplings that mate to the washer chassis and drain hose. Proper fitment requires matching the pump’s mounting points, connector pinout, and shaft coupling to the washer model; a correct replacement shares the same mechanical footprint and electrical connector so the control board and drain plumbing interface without modification. In normal operation the motor produces sufficient torque to overcome backpressure and any one‑way valve resistance while the impeller generates flow; degradation shows up as reduced flow, noise, or leakage rather than changes in electronic control outputs.
- No drain or very slow drain - tub remains full after drain cycle ends.
- Humming or buzzing without rotation - motor receives command but the impeller is stuck or bearings seized.
- Excessive noise or grinding – foreign object contacting the impeller or damaged impeller vanes.
- intermittent operation – loose connector, wiring fault, or thermal protection cycling.
- Visible leak – failed seal, cracked housing, or loose hose clamp.
Diagnosing faults combines visual inspection with electrical measurements and functional checks. Verify that the control board issues the drain command and that the pump connector presents the rated supply voltage during that interval; if voltage is present and the pump does not turn, measure motor winding continuity and check for short to ground-an open winding indicates motor failure, a low but non‑infinite resistance with heavy current draw points to mechanical seizure or hydrodynamic jam. If the pump runs but flow is low, remove the inlet housing and inspect for lint, coin, or textile debris and verify the impeller blades are intact and free to rotate; a worn or cracked impeller can reduce flow even when the motor operates normally. For compatibility and repair decisions, compare mounting geometry, electrical connector, and performance behavior rather than relying solely on part number lists.
| Item | Description |
|---|---|
| No drain | control sends drain signal but no water moves - check voltage at pump, then continuity and mechanical blockage. |
| Hums but won’t spin | Voltage present, high current or thermal trips likely; inspect impeller and bearings for seizure or foreign object. |
| Leaks | External water at pump housing or hose connections – replace seals/housing or tighten/replace clamps. |
Replacement Considerations, Model Compatibility, and Installation Procedures for the 137311900 Pump
The 137311900 Frigidaire Washer Pump is a compact drain assembly that combines an impeller, motor, and seal in a single housing; understanding its mechanical behavior helps diagnose failures and select the correct replacement. Inspect the pump housing, mounting tab locations, electrical connector style, and discharge port diameter on the machine before ordering-thes physical attributes determine compatibility more reliably than model name alone. The pump depends on an intact impeller, a reliable shaft seal, and correct motor supply to evacuate tub water; common failure modes are worn seals (leading to leaks), damaged impellers (reduced flow or clog), and motor windings or brushes that fail electrically. For practical verification, technicians should compare the OEM part number, harness pinout, and hose routing to the service manual or a known-good unit rather than relying solely on visual similarity, as some Frigidaire models use an identical pump body but different electrical connectors or check-valve assemblies.
- Disconnect power and water supply before access-verify no voltage at the connector with a meter.
- Drain residual water and remove clamps on the inlet/discharge hoses to prevent spills during removal.
- Label or photograph wiring and hose positions so they can be reinstalled exactly; transfer seals or grommets if required.
- Check the replacement for identical mounting holes, pump outlet orientation, and connector type; adaptors are sometimes necessary.
- After installation, run a drain/spin cycle to check for proper flow, abnormal noise, and absence of leaks.
During installation, secure fasteners to the manufacturer’s torque or snugness recommendations to avoid distorting the plastic pump housing and to maintain proper seal compression; overtightened clamps can split the outlet, while under-tightened clamps can cause leaks and air ingestion that reduce prime. Technicians should also verify electrical operation by measuring supply voltage at the pump connector during a drain command and checking motor current against typical service values-excessive current suggests a binding impeller or bearing failure, while no current indicates a control or wiring fault upstream. If the washer incorporates a lint trap or check valve in the discharge path, inspect and clean those components before declaring the pump defective, since restricted flow upstream can mimic pump motor problems.

Q&A
What is the Frigidaire part 137311900?
Part 137311900 is a washer drain pump assembly sold as an OEM replacement for certain Frigidaire/Electrolux top‑load washing machines. It is the motorized pump that removes wash water from the tub and sends it out through the drain hose. Always confirm compatibility by matching your washer’s model number to the part number or using the manufacturer’s parts lookup.
What common symptoms indicate the pump (137311900) is failing?
Common signs include the washer not draining, standing water in the tub, unusual grinding or humming noises during the drain cycle, water leaking from the pump area, and recurring drain error codes on the machine. Some of these symptoms can also be caused by clogs or faulty drain valves, so verify the pump before replacing it.
How can I check whether the pump is clogged or simply failed?
first, disconnect power and inspect the pump inlet and discharge hose for debris (coins, lint, small clothing items). remove any visible obstructions. If the pump spins freely by hand and there are no blockages but it still won’t pump water, the motor might potentially be electrically failed. For further diagnosis you can check for continuity across the pump motor terminals with a multimeter (unplugged). If there is no continuity or the resistance is far outside the manufacturer’s spec, the motor is likely bad.
Can I test the pump electrically and is it safe to do so at home?
You can perform basic electrical checks: with the washer unplugged, measure continuity across the pump motor terminals. A working motor normally shows a low but finite resistance (varies by model). To verify the pump receives power during the drain cycle requires live-voltage checks and should be done only by someone comfortable and qualified to work with mains voltage-use proper PPE and follow safety procedures. If you are unsure, hire a qualified appliance technician.
Does replacing part 137311900 require special tools or skills?
Replacement typically requires basic hand tools (screwdrivers, pliers) and access to the washer’s back or front panel depending on model. The job involves disconnecting power, shutting off water (if applicable), removing the access panel, disconnecting electrical connectors and hoses, and swapping the pump. While many DIYers with mechanical experience can perform this, if you are uncomfortable with electrical connections or working inside appliances, have a technician do the replacement.
How long does a pump like 137311900 usually last, and can I prevent future failures?
Service life varies with usage and load conditions; many pumps last 5-10 years. Preventive measures include emptying pockets before washing, using appropriate load sizes, cleaning the washer’s filter/trap regularly (if present), and keeping the drain hose free of kinks. Addressing small leaks or unusual noises early can also prevent more severe failures.
Are there aftermarket alternatives, and how do I choose between OEM and aftermarket pumps?
Yes-there are aftermarket pumps that fit the same models. OEM pumps provide a direct manufacturer-specified replacement and typically ensure fit and performance; aftermarket pumps can be less expensive but quality varies.Choose a reputable supplier with good reviews and a warranty, confirm connector/hose compatibility, and check return policy in case of fitment issues.
What should I know about warranty, installation cost, and disposal of the old pump?
New pumps generally come with a limited warranty (commonly 90 days to one year-check the seller). If you hire a technician, labour charges vary by region; many shops provide a flat service fee plus parts. Dispose of the old pump according to local regulations for electronic and metal waste-many parts are recyclable. If the pump leaked oil or fluid, handle it as potentially contaminated and follow local hazardous-waste guidance.
The Conclusion
The 137311900 Frigidaire washer pump is an essential component that manages water movement during wash and drain cycles.
