137311900 Frigidaire Washer Pump is a replacement drain pump assembly used in many Frigidaire residential washing machines; it is indeed a compact, electrically driven pump that evacuates wash and rinse water from the tub and directs it into the household drain. The component typically consists of a small electric motor, an impeller enclosed in a plastic housingand integral mounting and electrical connectors that allow it too be fitted to the washer’s drain port.
Inside the appliance, the pump’s primary role is to remove water from the tub at the end of fill and spin cycles and to clear water from the detergent and pump housings between cycles. It interfaces mechanically with the tub and drain hose and interfaces electrically with the washer control board and cycle timer; it is also functionally linked to level-sensing components (pressure switch or water level sensor) and door/lid safety interlocks that determine when drain operations are permitted. Proper sealing, unobstructed impeller operationand reliable electrical connection are essential for the pump to maintain expected flow rates and to avoid leaks, noiseor motor failure.
This article will describe the pump’s function and typical construction, outline compatibility and fitment considerations for technicians and owners, summarize common failure symptoms (such as: no drain, persistent humming, excessive vibrationor leaks), and provide a structured approach to troubleshooting and diagnosis. It will also cover practical replacement considerations such as mounting orientation, hose and clamp inspection, electrical checks to isolate motor faultsand safety precautions to follow during service.

Function and Role of the Frigidaire Washer Drain Pump in Water Removal and Flow Control
The primary function of the 137311900 Frigidaire Washer Pump is to evacuate wash and rinse water from the tub and force it thru the drain hose to the household plumbing. This component is a sealed motor-and-impeller assembly designed to run on the appliance’s AC supply and to deliver a relatively high volumetric flow at low head for short intervals during the wash cycle. In operation the pump is energised by the washer’s electronic control or timer only during drain or intermittent purge operations; hydraulic design choices such as impeller size, volute geometryand any integrated check valve determine how quickly the tub empties and how the pump responds to partial restrictions or vertical lift in the drain run. Technician observations such as a humming motor with no fluid movement, slow drain, or foreign-object debris caught in the inlet are consistent with worn or obstructed pump components rather than control-system faults in many cases.
The pump also plays a central role in flow control within the machine’s water management system by working in concert with the water-level sensor and the control electronics: the controller energises the pump until sensors report that the target drain level is reached,so pump hydraulic performance (flow vs. head) directly affects cycle timing and spin behavior. Practical compatibility checks for replacement include verifying the electrical connector pinout, mounting flange and seal dimensionsand rotational direction of the impeller; measuring the motor winding resistance with a multimeter and confirming free impeller rotation are fast functional tests before installation.Typical service symptoms, diagnostic checks, and a short technical reference are provided below to aid repair decisions.
- Common symptoms: no drain but motor hums, intermittent draining, audible grinding or rattling, leaks at pump housingor high current draw.
- Basic checks: inspect inlet screen for debris, verify connector voltage during drain command, measure winding resistance, and confirm correct mechanical fitment.

How the 137311900 Frigidaire Washer Pump Operates Inside the Appliance: Mechanical, Electricaland Hydraulic Interaction
The 137311900 Frigidaire Washer Pump is a compact centrifugal drain pump assembly that couples a small electric motor to a molded impeller and housing. Mechanically it mounts to the washer tub and connects to the drain hose; the impeller converts motor torque into fluid flow and pressure required to evacuate the wash tub during drain and spin phases. Electrically the pump receives switched supply from the washer control board (often through a harness and connector) and will run only when the controller energizes the appropriate circuit, so correct connector orientation and matching coil voltage are required for compatibility.In practise, technicians verify fit by matching mounting tabs, hose diameter, and connector pinout rather than relying solely on model numbers, as several Frigidaire model series use similar pump assemblies with slight variations in outlet orientation or harness length.
Inside the appliance the pump’s mechanical, electricaland hydraulic subsystems interact continuously: the motor provides rotational energy, the impeller imposes a centrifugal pressure head that overcomes static water level and discharge backpressureand the housing and hoses define flow restrictions and leakage paths. Common failure modes illustrate these interactions – a seized impeller or blocked inlet reduces flow despite motor voltage, worn motor bearings or brush wear produces noise and reduced RPM, and a split seal or cracked housing causes leaks even if the motor runs. Replacing the pump typically resolves symptoms such as no drain, weak flow, humming without rotationor visible leakage, but verification with a multimeter, inspection of the discharge hose and check valveand confirmation of control-board output will identify weather the fault is mechanical, electricalor hydraulic before replacement.
- No drain or slow drain: possible impeller clog or hydraulic restriction.
- Humming but no spin: electrical rotor stall, seized bearingsor jammed debris.
- Leaking at pump housing or seals: mechanical seal failure or cracked housing.
- Intermittent operation: wiring harness, connector corrosionor control output issue.

Common failure Symptoms and Diagnostic Tests for Pump Motor, Impeller, and Seals
The 137311900 Frigidaire Washer Pump is a combined motor-and-impeller assembly that evacuates wash water through the drain system while relying on a shaft seal to keep fluids away from the motor windings. In normal operation the motor produces sufficient torque to spin the impeller against hydraulic and debris load; failures typically present as loss of flow, unusual noise, humming without rotationor external leakage where the seal or housing has been compromised. Because the pump is an integrated mechanical and electrical component,compatibility is dictated by mounting points,connector type,and seal orientation rather than cosmetic appearance-replacement units must match these interfaces to ensure proper fit and reliable shaft sealing under load. Practical examples include a trapped sock that reduces flow and increases motor current, or a failed seal that allows water intrusion and progressive winding damage.
Technicians diagnose pump problems through a combination of visual, mechanical and electrical checks.First, visually inspect the housing and impeller for foreign objects and evidence of leaks; manually confirm the impeller rotates freely and without axial play. For electrical verification, disconnect power before accessing wiring, then measure continuity across the motor terminals (shoudl show a closed winding) and insulation to chassis (should be open/no continuity). During a controlled drain cycle measure voltage at the pump connector (nominally ~120 VAC on most U.S. machines) and compare motor current to service data-a hum with low/no rotation typically indicates mechanical binding or a seized impeller, while normal rotation with low flow points to impeller damage or partial blockage.If the pump passes bench electrical tests but leaks or noise persist, replace the assembly to restore reliable sealing and hydraulic performance.
- No drain: inspect for obstructions, confirm voltage at connector, verify continuity of motor windings.
- Humming without spin: check impeller for jams,measure motor current for overload,confirm shaft turns freely by hand.
- Intermittent operation: inspect wiring harness and connectors, test switch/relay operation that supplies the pump.
- External leakage: examine shaft seal and housing for cracks or coolant tracks; replace pump if seal integrity is lost.
- Excessive noise or vibration: look for debris trapped against the impeller, worn bearingsor bent impeller blades.
| Item | Description |
|---|---|
| Continuity test | Closed winding between motor terminals; no continuity between windings and chassis (no short to ground). |
| Voltage check | Measure supply at connector during drain command (nominally ~120 VAC on U.S. models) to isolate control vs. pump failure. |
| Impeller spin | Impeller should rotate smoothly by hand; binding indicates obstruction or bearing failure causing high current draw. |
| Leak inspection | Visual check for coolant/water at the pump seam or shaft; wetness at motor indicates seal failure and likely replacement. |
Replacement Considerations and Step-by-Step Installation for the 137311900 Pump Assembly
The 137311900 Frigidaire Washer Pump is a motor-driven drain pump assembly that moves wash water from the tub to the household drain during drain and spin cycles. It consists of a small electric motor, an impellerand a molded housing with inlet and outlet ports; electrical activation and run time are controlled by the washer’s control board or timer. Technically, compatibility hinges on mechanical mounting, inlet/outlet orientationand the electrical connector type – verify that the pump’s mounting tabs, hose diametersand terminal style match the machine before replacement. Common failure modes include seized bearings, clogged impellers, worn brushes (in brushed motors)and housing leaks; troubleshooting often begins with verifying continuity at the pump terminals and checking for obstruction in the discharge hose or coin trap.
Replacement requires basic hand tools and attention to wiring and sealing details. before beginning, disconnect power and shut off the water supply, then drain residual water from the tub to limit spillage. Remove the access panel,document the hose and wiring configuration with a photo or labels,remove hose clamps and electrical connector,and unfasten the pump mounting screws. When installing the new pump, transfer or replace any gaskets, position the unit so inlet/outlet orientation matches the original, secure the mounting hardware evenly, reconnect hoses with new or inspected clampsand restore power for a short drain test while checking for leaks and abnormal noise. Practical tips: replace brittle hoses or clamps, avoid overtightening clamps on plastic fittingsand run a diagnostic drain/spin to confirm both electrical operation and hydraulic sealing.
- Power off and water off; drain tub before disconnecting hoses.
- Label or photograph electrical connectors and hoses for correct reinstallation.
- Remove mounting screws and clamps; extract the old pump and inspect gaskets.
- Install new pump, transfer gasket, reconnect hoses and terminals, then secure clamps.
- Restore power and run a short drain cycle; check for leaks and listen for abnormal vibration.

Q&A
What is the Frigidaire part 137311900?
The 137311900 is the OEM drain pump assembly used on certain Frigidaire (and some Kenmore/White-Westinghouse) top-load and front-load washing machines. It is indeed responsible for pumping the wash water out of the tub and into the household drain during drain and spin cycles. Always confirm compatibility with your washer model number before purchasing.
What are the common symptoms of a failing 137311900 washer pump?
Typical signs include: washer won’t drain or spins with water still in the tub, a loud grinding or humming noise during drain, intermittent draining, visible leaks from the pump area, or machine error codes related to drainage. Some symptoms can also be caused by clogged hoses or blocked pump impellers by debris or small items.
How can I test the 137311900 pump to see if it’s defective?
First disconnect power to the washer. Remove the pump electrical connector and use a multimeter to check for continuity across the pump motor terminals – an open circuit indicates a failed motor. You can also check for obvious mechanical blockage by inspecting the impeller and housings for debris. If the motor gets power during a drain cycle but doesn’t run, the pump is likely bad.
Can the 137311900 pump be repaired or should it be replaced?
Minor issues like debris-jammed impellers or torn hoses/clamps can often be fixed without replacing the pump. Though, if the motor has burned out, bearings are noisy/worn, seals are leakingor electrical components fail, replacement is the recommended solution. As drain pumps are relatively inexpensive and critical to operation, most technicians replace rather than rebuild them.
How do I replace the 137311900 pump safely?
Unplug the washer and turn off the water supply. Access the pump by removing the appropriate access panel (front/bottom or back depending on model). Note hose and wiring locations, then disconnect the drain hoses (expect some residual water), release hose clampsand unplug the electrical connector. Remove mounting screws or clips and remove the old pump, then install the new unit in reverse order. Tighten clamps, reconnect wiring, restore powerand run a short drain cycle to check for leaks and proper operation.If unsure, hire a qualified appliance technician.
Do I need any special tools or parts to install the 137311900?
Basic hand tools (screwdrivers, pliers, nut drivers) and possibly a putty knife to release clips are usually sufficient.You’ll need replacement hose clamps if the originals are damaged. It’s a good idea to have a towel or small tray to catch water. No special electrical tools are required beyond a multimeter if you plan to test continuity.
Why does the new pump still not drain after installation?
If a new pump doesn’t drain, check for kinks or clogs in the drain hose or household drain, verify the pump electrical connector is fully seated, and confirm the pump is getting voltage during the drain cycle (use a multimeter carefully).Also verify the washer’s control board or timer is calling for the pump - a control fault or failed pressure switch can prevent the pump from running even if the pump is good.
Is there anything I should know about buying a replacement 137311900 pump?
Buy a pump that specifically lists compatibility with your washer model – OEM parts ensure fit and performance. Aftermarket pumps can be acceptable but verify fit, connector type, and mounting points. Check the seller’s return policy and warranty. Keep the old pump until you confirm the new one works, so you can compare connectors and hoses if needed.
