137311900 Frigidaire Washer Pump is a motor-driven drain pump assembly used in residential washing machines. It is indeed a compact electromechanical component consisting of a small electric motor coupled to an impeller housed in a molded pump body; the assembly is designed to lift and expel wash water from the tub to the household drain through attached hoses. As a replaceable service part, the pump typically includes mounting points, inlet and outlet ports, and an electrical connector that integrates with the washer’s wiring harness.
Within the appliance, the pump’s primary role is to remove water at the end of wash and rinse cycles and during certain intermittent operations such as spin or drain commands. It interacts directly with the tub, drain hose, and plumbing, and it is controlled by the washer’s control board or timer and coordinated with the water level/pressure sensing system and door or lid interlocks. Proper pump operation affects cycle timing, water removal efficiency, and overall safety; failures can lead to standing water, drainage errors, or secondary faults in associated sensors and electronics.
In this article readers will find a technical overview of the pump’s function and mechanical/electrical characteristics, guidance on verifying compatibility with specific Frigidaire models, common failure symptoms to recognize (such as, no-drain, humming, grinding, or leaks), stepwise troubleshooting procedures including basic electrical and obstruction checks, and practical replacement considerations such as disconnecting power, draining the tub, securing hose connections, and verifying mounting and electrical connections during reassembly. The information is intended to support informed diagnostics and safe, effective service decisions by technicians, engineers, and appliance owners.

functional Role and Required Specifications of the Washer Drain Pump Assembly
The 137311900 Frigidaire Washer Pump is an integrated drain assembly that removes wash water from the tub by converting motor torque into centrifugal flow through an impeller contained in a sealed housing. In service the assembly must present a clear flow path, intact shaft sealing, and a compatible electrical feed; typical failure modes seen in the field include humming without pump action (impeller jam or seized bearings), slow drain from partial blockage, and external leakage from degraded seals. Understanding the pump as a motor-plus-housing subsystem clarifies why both mechanical fit (mounting tabs, inlet/outlet diameter) and electrical compatibility must be checked before installation.
- Common symptoms: no drain with motor hum, intermittent draining, water leakage at pump body or hoses.
- Compatibility checks: match mounting orientation, hose ID/OD, and connector pinout rather than only matching model numbers.
- Diagnostic steps: inspect impeller for foreign objects,verify free rotation,and test motor continuity before replacement.
- Practical replacement considerations: replace the entire assembly if seals are compromised or if impeller/motor wear is evident to restore reliable performance.
Required specifications for a prosperous replacement include mechanical fit (mount tabs and overall envelope), hydraulic connection size, and electrical rating; always verify electrical rating and connector pinout against the appliance label to prevent damage. For example, a technician should confirm inlet/outlet hose diameters and clearance in the chassis, bench-check motor continuity and free impeller rotation, then perform a wet-cycle verification after installation to confirm expected drain times and absence of leaks. When documenting a repair,record observed symptoms and any debris found in the impeller so future troubleshooting can distinguish between installation errors and recurring pump/system issues.

How the 137311900 Frigidaire Washer Pump Operates Within the Washer Chassis
The 137311900 Frigidaire Washer Pump is a centrifugal drain pump assembly that mounts beneath the tub and converts motor torque into fluid flow to evacuate the wash chamber during drain and spin cycles. The assembly couples a small electric motor to a molded plastic volute and a molded impeller, with the inlet secured to the tub outlet and the outlet routed to the drain hose and check valve. When the washer control closes the pump relay, the motor accelerates the impeller to create a pressure differential that forces water out of the tub; restricted inlet screens, a chipped impeller blade, or a compromised housing seal reduce flow, can cause a low-speed hum, and may lead to motor overheating or premature failure.
Functionally the pump is coordinated with the washer’s control systems and mechanical plumbing: the control board calls for drain only after the lid/door interlock and spin state allow it, and the pressure/level switch confirms the water level before the pump begins prolonged operation. Compatibility for replacement requires matching the mounting flange, inlet/outlet hose diameters, and connector type so the pump seats correctly and the electrical harness mates without modification. For practical troubleshooting, technicians should check for obstructions at the inlet strainer, verify voltage at the pump connector during a drain call, inspect the impeller for damage, and confirm hose clamps and the check valve are installed correctly to preserve priming and prevent air ingestion.
- Activation: energized by control board/timer via pump relay during drain and spin cycles.
- Common symptoms: slow or no drain, humming, leaks at housing or hoses, overheating motor.
- Installation checks: correct flange orientation, secure hose clamps, compatible electrical connector.
- Maintenance points: clear inlet debris, inspect impeller and seal integrity, test for proper drain hose slope and check valve function.

Diagnostic Indicators and Common Failure Symptoms of the Pump Assembly
The 137311900 Frigidaire Washer Pump is the electro-mechanical subassembly that evacuates wash water from the tub by converting motor torque into impeller-driven flow. Internally it pairs a compact motor with a molded impeller and sealed housing; mechanical failures (blocked or damaged impeller, worn shaft/seal) reduce flow or cause leaks, while electrical faults (open windings, intermittent brushes or connector faults) prevent the motor from turning. Technicians typically confirm function by verifying that the impeller spins freely when the drive is turned by hand,inspecting the inlet/drain passages for foreign objects,and checking wiring continuity and connector integrity before replacing the entire pump assembly or control components for compatibility reasons with the chassis and drain plumbing of the specific frigidaire model.
Common diagnostic indicators are distinct and reproducible during the drain cycle: a humming motor with no flow usually indicates an obstruction or a broken impeller, a fully silent pump with no continuity typically indicates an electrical open, and visible leaking around the housing points to seal or crack failure. Practical troubleshooting steps include clearing the pump inlet and trap of debris (coins, lint, small clothing items), verifying the drain hose and check valve are not collapsed or kinked, testing motor leads with a multimeter for continuity and intermittent resistance changes, and observing pump behavior under load to distinguish a control/timing issue from a pump failure.
- No drain or very slow drain
- Humming noise without water movement
- Grinding or rattling noises (foreign object in impeller)
- water leaking from pump housing or seals
- Intermittent operation or no electrical continuity

Troubleshooting procedures and Diagnostic Tests for Pump Faults
The 137311900 Frigidaire Washer Pump is an electromechanical drain pump that moves wash water out of the tub via an impeller coupled to a small motor. Common faults include an impeller jam from foreign objects, internal seal or bearing wear that allows water intrusion, and electrical failures such as open windings or intermittent connections. Compatibility for replacement depends on mounting flange, electrical connector, and hose positions; a correct physical and electrical match is required for reliable operation. Technicians should visually inspect for debris, check the pump housing for hairline cracks or leaks, and verify that the impeller rotates freely by hand before applying power to avoid further damage to the motor or control electronics.
- Symptom: No drain; check hose blockage, pump inlet/outlet and drain trap before assuming pump failure.
- Symptom: Humming without rotation; test for seized impeller or failed motor windings.
- Electrical test: measure continuity across pump motor terminals and check for expected voltage at the harness during a drain cycle.
- Mechanical test: disconnect power, remove pump and attempt manual rotation; inspect for foreign objects and shaft play.
- Isolation test: apply rated supply to the pump off the machine (or use bench adapter) to confirm motor runs independently of the washer control board.
| Item | Description |
|---|---|
| Motor resistance (approx.) | 15-40 Ω measured across motor terminals (cold); values outside this range suggest winding damage or shorting. |
| expected control voltage | Model-dependent; many US washers drive the pump with mains-level AC during drain – confirm with the washer’s wiring diagram before testing. |
| Common failure modes | Impeller obstruction, bearing/seal wear, open/shorted windings, and connector corrosion. |
Diagnostic workflow: start with simple non-destructive checks (hose and trap clearance, manual impeller rotation), then confirm electrical integrity using a multimeter and verify that the control sends power to the pump during a drain command.If the harness shows correct voltage but the pump does not run or exhibits high current draw and noise, the pump motor has likely failed and should be replaced. If the pump shows open or shorted windings, or if leaks are present at the housing, replace the unit; if there is no voltage at the harness, trace the circuit back to timers, relays, or electronic control boards and inspect connectors and door/lid switches that interlock drainage operation.
