137311900 frigidaire Washer Pump is a replacement drain pump assembly designed for use in household washing machines. The component is an electric motor-driven pump with an integrated impeller and housing that mounts to the washer cabinet and connects to the tub drain outlet. As a field-serviceable part it typically includes the pump body, mounting flange, inlet/outlet ports and electrical connector or lead wires, and is intended to restore the mechanical and hydraulic function of the appliance’s drain path when the original pump fails.
Inside the appliance the pump’s primary role is to evacuate wash and rinse water from the tub during drain and spin cycles; it is part of the machine’s fluid-handling subsystem and interfaces directly with the tub outlet, drain hose, and external plumbing. It also interacts with the machine’s control system and sensors - the control board supplies power and timing, and water-level or pressure sensors determine when the pump is commanded to run. As it occupies both the hydraulic and electrical domains of the washer,common failure modes include impeller blockage or breakage,seal or bearing wear leading to leaks or noise,and electrical faults such as motor winding failure or connector issues.
In this article readers will find a technical overview of the pump’s function and construction, guidance on compatibility and how to confirm that 137311900 is the correct replacement for a given Frigidaire model, typical symptoms that indicate pump failure (for example, no drain, slow drain, loud noise, leaks, or relevant error codes), and high-level troubleshooting checks to distinguish hydraulic blockages from electrical defects. The article will also cover practical replacement considerations such as verifying connector and mounting orientation, inspecting and replacing seals or clamps, and post-replacement checks to confirm proper installation and leak-free operation.

Functional Role and Performance Specifications of the Washer Drain pump Assembly
The primary function of the 137311900 Frigidaire Washer Pump is to evacuate wash and rinse water from the tub during drain and spin cycles while resisting backflow from the household drain. The assembly combines a small induction motor,a molded plastic impeller and a sealed pump housing; the control board or timer applies mains voltage to the pump only during the drain phase,and the pump must develop enough flow and head to clear the drain hose and any in-line filter or trap. Compatibility-wise the unit is a direct-replacement style module for specific Frigidaire models, using standard spade terminals and a three-point mounting flange; proper replacement requires matching the electrical connector orientation, hose diameters and the sealing interface to avoid leaks or reduced flow performance after installation.
Performance is defined by electrical input,hydraulic output,and mechanical reliability: typical drive voltage for this series is nominal mains (120 V AC in U.S. market models),steady-state current in the low ampere range,and sufficient volumetric flow to empty a residential washer within a single drain interval. Common failure modes include impeller blockage from debris,bearing/seal wear causing noise or leakage,and electrical winding open-circuit or short. Troubleshooting uses a multimeter to verify continuity and applied voltage at the pump terminals during a drain cycle, inspection of the pump housing and inlet for foreign objects, and a manual spin test of the impeller to confirm free rotation; replacement is recommended when hydraulic output is reduced or electrical faults are present, and reinstallation must ensure secure hose clamps and a watertight seal at the pump-to-tub interface.
- Observable symptoms: no drain, slow drain, humming without rotation, water leakage at pump seals.
- Mechanical features: molded impeller, sealed motor housing, quick-disconnect spade terminals.
- Installation notes: match hose diameter and mounting boss orientation; tighten clamps to manufacturer torque to prevent leaks.

How the 137311900 frigidaire Washer Pump Works Inside the appliance: Motor, impeller, and Electrical Interfaces
The 137311900 Frigidaire Washer Pump combines a compact electric drive and a molded impeller in a sealed plastic housing to evacuate wash and rinse water from the tub. The drive is a small, single‑phase motor designed for intermittent duty and direct coupling to the impeller; the impeller itself is a centrifugal type with backward‑curved vanes that shed lint and small soft debris while moving water through the discharge port. The assembly relies on a close clearances design so partial blockages or entangled fabric can restrict flow and increase motor load, producing characteristic humming or tripping symptoms under load.
Electrical interface and mechanical compatibility determine whether this pump functions correctly in a given machine: typical North American installations use 120 VAC supply with two motor terminals plus a chassis ground, and the pump often includes an over‑temperature protector or thermal cut‑out in series with the motor winding. Technicians should verify connector pinout, mounting flange alignment, and discharge hose orientation before installation; common diagnostic checks include measuring winding continuity, applying controlled power to verify free rotation of the impeller, and checking for voltage at the harness during a drain cycle. Inservice behaviors such as slow draining with the motor running,a loud bearing noise,or a motor that does not energize despite correct voltage each point toward specific faults (partial blockage,mechanical wear,or open winding/failed protector respectively).
- Simple diagnostic checks: verify voltage at the pump during drain; check impeller for debris or damage; measure motor winding resistance.
- Common failure modes: blocked impeller, worn bearings, failed thermal protector, or broken electrical connector.
- Compatibility factors: match voltage, connector type, and mounting orientation when replacing the unit.

Common Failure Symptoms and Diagnostic Indicators for Pump Operation and Drainage Faults
The 137311900 Frigidaire Washer Pump is the centrifugal drain assembly that evacuates wash and rinse water from the tub during the drain and spin portions of the cycle. It mounts to the washer cabinet and interfaces with inlet and outlet hoses, a housing seal, and the machine’s electrical harness; proper replacement requires matching the pump flange and connector orientation to the cabinet and hose routing. Typical mechanical failure modes include impeller damage or blockage (lint, coins, fabric fibers), bearing or motor wear that produces excessive noise or reduced flow, and seal or housing cracks that produce leaks. Understanding the pump’s physical interfaces and expected behavior-free-spinning impeller when powered-off, rapid water displacement when powered-on-helps distinguish pump faults from hoses, traps, or control-board issues.
Technically useful diagnostic indicators include electrical, mechanical, and flow checks: verify presence of control voltage at the pump connector during the drain command, confirm continuity of the motor windings, and inspect for obstructed discharge or foreign objects at the impeller. Practical examples: a humming motor with no water movement commonly indicates an obstructed or broken impeller; no hum and no applied voltage points to a control or timer fault; leaks at the pump body or mounting suggest seal or housing failure and require replacement. Field technicians should document symptoms,isolate the pump from hoses during bench testing where feasible,and compare observed behavior against these indicators before replacing additional components.
- No drainage/standing water in the tub
- Motor hums but little or no water is pumped
- Unusual grinding, rattling, or loud operation
- Visible leaks at pump housing or seals
- Intermittent operation or failure only on certain cycles

Compatibility, Replacement Considerations, and Step‑by‑Step Installation for the 137311900 Frigidaire Washer Pump
The 137311900 Frigidaire washer Pump is a centrifugal drain pump assembly that evacuates wash water from the tub through a molded housing and impeller driven by a small electric motor. In normal operation the pump runs only during drain and some spin cycles; common functional symptoms of failure include no drainage, reduced flow, a loud humming or grinding noise, or leakage at the housing or hose connections. Compatibility is resolute by physical mounting points, inlet/outlet hose diameters, the electrical harness connector and the motor voltage; confirm these features against the washer’s parts diagram or the label on the old pump before ordering a replacement.
When replacing the pump,prioritize matching mechanical fit and electrical interface rather than relying solely on a part number-many pumps share similar shapes but differ in tab placement,gasket type,or connector pinout. Typical replacement work requires removing panels, draining residual water, disconnecting hoses and the harness, replacing the pump and its gasket, and testing for leaks and proper drain timing; verify the pump impeller turns freely before reassembly and inspect the drain hose and trap for obstructions that can mask a pump problem.
- Disconnect power: cut mains power before any access or water removal.
- Drain remaining water from the tub (use a bucket and lower the drain hose if accessible).
- Remove access panel(s) and locate the pump; support the pump when undoing hoses and fasteners.
- Disconnect the electrical harness and remove mounting screws or clips; replace the pump and gasket, reattach hoses and connector.
- Restore power, run a short drain test, and check for correct flow, noise, and leaks.
