137311900 Frigidaire Washer Pump is a motor-driven drain pump assembly used in Frigidaire residential washing machines. It is a compact electromechanical component that combines a small electric motor, impeller, and housing to move water out of teh tub and into the household drain during drain and spin cycles. The part is typically installed at the base of the washer and connects to the tub and external drain hose via molded ports and clamps.
Inside the appliance the pump’s primary role is to evacuate wash and rinse water from the tub and maintain appropriate flow thru the drain line; this action is essential for completing wash programs and preventing standing water. The pump interfaces with the machine control board and the washer’s cycle logic (receiving power and run commands), while mechanically connecting to the tub, drain hose, and any in-line filters or lint traps. Faults in the pump can affect related systems such as the water level/pressure sensing, door or lid interlocks (if a drain is required before these unlock), and error-detection routines executed by the controller.
In this article readers will find a technical description of the pump’s function and typical construction, guidance on compatibility and identification of the 137311900 unit, common failure symptoms and diagnostic steps, practical troubleshooting checks (electrical, mechanical obstruction, and leakage inspection), and considerations for safe replacement and proper installation.The content is intended to help technicians, engineers, and appliance owners make informed decisions about repair and replacement while minimizing risk to equipment and personnel.

Function and Role of the Washer Drain Pump in Frigidaire Laundry Systems
The 137311900 Frigidaire Washer Pump is the electromechanical drain pump assembly responsible for evacuating wash water from the tub during drain and spin phases. It converts electrical drive input from the control board into rotational motion at the impeller, producing the flow and head necessary to push water through the drain hose and any inline check valve. In normal operation the pump only receives power during targeted cycle states; if the control board supplies voltage and the impeller is free to turn, the pump should deliver measurable flow. The pump assembly includes the impeller housing, inlet/outlet ports sized for factory drain hoses, a wiring connector that mates to the Frigidaire harness, and mechanical mounting points that must align with the washer chassis for a sealed installation.
- Common failure symptoms: no drain, pump hum without rotation, leaks at housing or hose connections, and diagnostic error codes indicating “drain” faults.
- Installation notes: confirm connector pinout and drain-port diameter, secure hose clamps, and ensure the pump gasket is seated to avoid air leaks that can impede siphoning.
- Service checks: listen for motor sound, inspect for foreign-object obstruction, verify continuity at the pump windings, and measure control-board output voltage per the service manual before replacing the unit.
Functionally, the pump acts as both a water mover and a system point that can limit a washer’s cycle progression when it fails; the controller waits for drain completion before advancing to spin or final rinse states. Technicians should cross-reference model compatibility and part numbers in the service manual-mounting geometry, harness connector style, and outlet orientation must match the washer model to avoid installation issues. In practice, replace the pump when the impeller is seized, the motor shows open or shorted windings, or persistent blockages have damaged the housing; otherwise troubleshooting the drain path (hose kinks, standpipe restrictions, and sink/trap conditions) often restores normal operation without pump replacement.
How the 137311900 Frigidaire Washer Pump Works Inside the appliance
The 137311900 frigidaire Washer Pump is the centrifugal drain pump assembly used to move wash water out of the tub during the drain and spin portions of the cycle. Inside the appliance the pump houses a small electric motor coupled to an impeller; when energized, the motor spins the impeller to create flow and discharge through the pump outlet. The pump assembly also includes mounting flanges, a molded housing that seals to the washer chassis, and a set of electrical terminals or a harness that must match the washer’s connector. Technicians should verify both the physical mounting pattern and the electrical connector before replacing the unit to ensure compatibility with a given Frigidaire model.
Functionally, the pump’s behavior is straightforward: it runs when the control board commands a drain and stops when the tub is empty or the cycle advances. Common failure modes include an obstructed impeller,worn motor bearings that cause noise or reduced flow,and cracked housings that lead to external leaks. For troubleshooting, check for continuity across the motor terminals, manually inspect the impeller for debris, and confirm that the control board is supplying voltage during a commanded drain. Practical examples: a washer that stalls on drain with a humming sound usually indicates a seized impeller or jammed shaft; intermittent draining frequently enough points to a failing motor winding or a loose connector.
- Typical symptoms: no drain, slow drain, loud humming/grinding during drain, visible leaks at the pump housing.
- compatibility checks: match part number, mounting tabs, outlet hose diameter, and electrical connector type.
- Field tests: manual impeller spin, continuity test across motor leads, and applying controlled mains voltage for a bench test if safe and permitted.

Common Failure Symptoms and Diagnostic Indicators (electrical, mechanical, and hydraulic)
The 137311900 Frigidaire Washer Pump is a motor-driven drain pump assembly that evacuates wash water; failures present differently depending on whether the fault is electrical, mechanical, or hydraulic. Electrical failures commonly show as no operation during the drain cycle despite control commands – a technician will verify voltage at the pump connector, continuity of the motor windings, and abnormal current draw with a clamp metre. Mechanical issues usually manifest as loud grinding,rubbing noises,or a pump that spins but produces little flow; these indicate worn bearings,a damaged shaft or impeller,or foreign-object jamming. Hydraulic symptoms include slow or partial draining, water remaining in the tub, or intermittent draining caused by clogged hoses, filters, or discharge paths; compatibility between pump discharge orientation and the washer’s plumbing can also affect perceived performance after replacement, so match mounting, connector pinout, and voltage rating when selecting a replacement pump.
- No drain but pump clicks or relay engages – frequently enough an electrical open winding or failed motor capacitor; measure voltage and continuity.
- Loud grinding or vibration – typically mechanical wear or foreign debris in the impeller housing; inspect and spin the impeller by hand.
- intermittent operation – can be a loose connector,thermal protection cycling,or intermittent control signal; probe during a drain cycle to isolate source.
- Water remains after pump runs - indicates hydraulic restriction such as kinked hose, clogged lint trap, or blocked pump inlet.
| Item | Description |
|---|---|
| No power at connector | Control board or wiring fault; verify command voltage during drain cycle before replacing pump. |
| Continuity short/open | Motor winding failure; replace pump assembly when windings show open circuit or short to ground. |
| High current draw | Mechanical binding or seized bearings; inspect impeller and housing, replace if binding persists after cleaning. |
| Normal motor operation but no flow | broken impeller, internal hydraulic leak, or external blockage; remove and inspect the hydrodynamic parts and hoses. |
To distinguish root causes in the field, run the washer through a drain cycle while measuring voltage at the pump plug and observing current draw: presence of correct voltage with no motor rotation implicates the pump motor or internal mechanical seizure, whereas absence of voltage points to control or wiring faults.physically inspect the discharge hose, pump inlet screen, and sump area for debris first, then remove the pump to check impeller freedom and shaft play; tangible examples include coins or textile clips lodged in the impeller cavity that produce a grinding noise and reduced flow. Replace the pump when electrical tests show winding faults, when bearings or impeller damage are observed, or when hydraulic wear cannot be cleared – ensure the replacement matches the washer’s mounting, connector arrangement, and electrical rating for reliable operation.
replacement Considerations and Installation Procedures for the Pump Assembly
The 137311900 Frigidaire Washer Pump is a centrifugal drain pump assembly that removes wash water from the tub and feeds it into the household drain. Technically, the assembly combines a small AC motor, an impeller, and a molded housing with inlet and outlet ports; its normal behavior is a rapid, high-flow discharge during drain and spin cycles. Failure modes include impeller obstruction from foreign objects, bearing or motor winding failure (open or short), and leaking seals or cracked housings that reduce suction. when selecting a replacement, match the pump housing flange, mounting tab locations, hose diameter, and electrical connector style to the machine – physical fit and connector compatibility are as important as the OEM part number to ensure correct alignment and reliable sealing against leaks.
Proper installation begins with basic safety and ends with a functional drain-test: disconnect power and water and remove standing liquid before loosening hoses. Support the pump during removal to prevent strain on the hoses and wiring, note harness pin positions or photograph them before unplugging, and inspect the inlet screen and impeller for debris before fitting the new unit. Reuse of old clamps, grommets, or seals is a common source of post-repair leaks, so replace these if damaged; after securing the pump and reconnecting wiring and hoses, run a short drain/spin cycle while checking for leaks, abnormal vibration, or persistent humming (which indicates electrical or mechanical faults). For checklist-style guidance, verify the following items during replacement:
- Visual match of mounting tabs, inlet/outlet orientation, and connector type to the original pump.
- Impeller spins freely by hand and inlet screen is clear of debris before installation.
- Wiring harness pins are correctly seated and secured; test continuity if motor failure is suspected.
- new clamps/grommets are used where rubber parts show wear to prevent leaks.
- After reassembly, perform a drain test and inspect for leaks and abnormal noise.

Q&A
What is part 137311900 for a Frigidaire washer?
137311900 is the replacement drain (wash) pump assembly used on a range of Frigidaire washers. It contains the pump housing, impeller and motor and is what evacuates water from the tub during the drain/spin portions of the cycle. To be certain it fits your machine, compare the part number to the parts list for your washer model (the model tag is usually on the door frame or rear panel) or check with an authorized parts vendor.
What symptoms indicate the 137311900 pump is failing?
Common symptoms are: washer won’t drain or leaves water in the tub; long or stuck drain cycles; audible humming or grinding from the bottom/front of the machine during drain; leaking from the pump area; and drain-related error codes on the washer display. Some problems may also be caused by clogged hoses or a blocked pump housing rather than a motor failure.
How can I safely test whether the pump is bad?
Start by unplugging the washer and checking the pump inlet/outlet and the trap for debris (coins, hair, small objects). Manually inspect the impeller for free spin. With the washer powered on and set to a drain cycle you can check for voltage at the pump connector – on U.S. models this is typically ~120 VAC - but this step should only be done by someone pleasant working with live electrical circuits. If voltage is present during the drain cycle and the pump does not run, the pump motor is defective. If there is no voltage, diagnose control board, timer, or wiring.You can also check the motor for electrical continuity with a multimeter; an open circuit indicates a failed motor windings.
What are the general steps to replace the 137311900 pump?
Typical replacement steps: 1) Unplug the washer and turn off water. 2) Drain as much water as possible (use the emergency drain or a bucket).3) Access the pump (lower kick panel, front panel or rear panel depending on model). 4) Take pictures or mark hose positions, then loosen hose clamps and remove inlet/outlet hoses. 5) Disconnect the electrical connector(s) and remove mounting screws/clips holding the pump. 6) Install the new pump in the same orientation, reconnect electrical connector and hoses, secure clamps, and reassemble panels. Test with a short drain cycle to confirm operation and check for leaks. Always follow model-specific instructions and safety precautions.
Can the pump be cleaned or repaired instead of replaced?
Often the pump can be cleared of debris (small coins, fabric, lint) without replacement if the motor runs and the impeller is intact. However, motor failures, worn bearings, or broken impeller blades usually require replacing the entire pump assembly. The motor itself is typically not serviceable, and disassembling sealed motor housings is not recommended.
Why is the pump noisy even if it still drains?
Noise while draining can come from several sources: objects striking the impeller, worn bearings in the pump motor, a cracked or damaged impeller, loose mounting hardware causing vibration, or cavitation from restricted water flow. If noise is accompanied by reduced flow or overheating smells, replacement is recommended.
Is it better to buy the OEM 137311900 or an aftermarket pump?
OEM parts (frigidaire-branded or manufacturer-authorized) ensure correct fit, mounting points and performance. Many reputable aftermarket pumps are equivalent and can be less expensive, but quality and warranty vary. If you choose aftermarket, verify electrical specifications, hose connection sizes, mounting orientation and that it’s listed as compatible with your washer model.
Where can I buy part 137311900 and does it come with a warranty?
You can purchase the pump through Frigidaire/Electrolux parts websites, authorized appliance parts stores, major online retailers, or local repair shops.Warranties vary by seller and manufacturer-some vendors offer limited warranties (commonly 90 days to one year). Keep your receipt and verify the return/warranty policy before purchase.If the washer is still under manufacturer warranty, contact Frigidaire service first.
