The 137311900 Frigidaire Washer Pump is a motor-driven drain pump assembly used in Frigidaire residential washing machines; it is indeed the mechanical and electrical component responsible for moving wash and rinse water from the tub to the household drain during the drain and spin portions of a cycle.
As a drain pump, this component houses a small electric motor coupled to an impeller and is mounted to the washer’s chassis with inlet and outlet ports that connect to the tub and drain hose. It interacts directly with the washer’s control board and sensors (wich command pump operation), the tub and drain plumbing (which convey water)and associated mechanical fittings and seals; electrically it typically connects via a harness to receive switched mains power from the controller and must resist debris, lint and residual moisture while maintaining a water-tight interface with the cabinet.
In this article you will find a technical overview of the pump’s function and construction, guidance on verifying compatibility with specific Frigidaire models, common failure symptoms (for example: no drain, weak flow, loud bearings or leaks), basic troubleshooting checks a technician or informed owner can performand practical replacement considerations such as verifying part numbers, inspecting seals and hosesand post-installation testing and safety precautions.

Function and Role of the Drain pump in Frigidaire Washer Water Handling
The 137311900 Frigidaire Washer Pump is the electromechanical component responsible for evacuating wash water from the tub during drain and spin cycles. It uses a compact electric motor coupled to an impeller housed in a molded plastic body; when the motor runs the impeller converts rotational energy into centrifugal flow, drawing water from the tub through the inlet and forcing it out the drain hose. In practical operation the pump must overcome the static head of the drain line and any minor restrictions (lint, small debris) while preventing backflow into the tub. The pump is designed as a direct-fit replacement for Frigidaire washers that specify this part number and interfaces with the washer’s control board and wiring harness, so compatibility with the machine’s voltage and mounting points should be verified before installation.
- Primary function: remove wash and rinse water quickly to allow spin and cycle progression.
- Common symptoms of failure: no audible pump motor sound, humming without flow (impeller jam or electrical fault), persistent leaksor slow draining.
- Design features: impeller-driven flow, molded inlet/outlet ports, electrical connector for the OEM harness; some assemblies include a small integrated check valve or mounting bracket.
From a service perspective, diagnosing the pump focuses on mechanical obstruction, electrical continuityand hydraulic resistance. A clogged inlet, trapped coinor dislodged sock will often produce a rapid rise in motor current and either a stall (humming) or stopped pump; measuring line voltage at the pump connector during a drain command distinguishes control issues from pump faults.Replace the unit when the impeller is damaged, seals are leakingor motor windings show an open/short condition. When selecting the 137311900 Frigidaire Washer Pump as a replacement,confirm the plug type,mounting orientation,and local mains rating (typically 120 VAC for North American models) to ensure correct operation and to avoid repeated failures due to mismatched hardware or installation errors.

How the 137311900 Frigidaire Washer Pump Works Inside the Appliance
The 137311900 Frigidaire Washer Pump is an electrically driven centrifugal drain pump located at the base of the washer that evacuates tub water through the drain hose. Inside the appliance the pump couples a compact motor to a molded impeller inside a volute-style housing; when the washer control board applies voltage the motor spins the impeller, producing flow and pressure sufficient to overcome the drain hose elevation and any in-line resistance. The housing design and one-way geometry limit backflow into the tuband the assembly works together with the water level sensing and control circuitry so that drain cycles stop when the tub reaches the target level or when a control algorithm ends the drain phase.
in practical service terms, the pump’s mechanical fit, outlet orientationand electrical connector must match the washer model for a proper replacementand the same pump assembly can appear across multiple Frigidaire top- and front-load models with minor variations in mounting. Typical failure modes are mechanical (impeller blockage from lint or foreign objects, bearing wear causing noise or seizure) and hydraulic (cracked housing causing leaksor reduced flow from partially blocked inlets); electrical failures such as open windings or poor connector contacts also occur. For troubleshooting, verify control outputs and power to the pump, inspect the drain path and lint traps for restrictionsand confirm that the pump rotor turns freely before replacing the unit to avoid misdiagnosing control-system or plumbing issues.
- Humming without flow: impeller jam or seized bearings.
- No operation: check power at the connector and control board output.
- Slow draining: lint trap, kinked hoseor partial impeller blockage.
- Leaks: inspect pump housing, seals, and hose clamp connections.

Common Failure Symptoms and Diagnostic Tests for the Washer Pump Assembly
137311900 Frigidaire Washer Pump is a motor-driven drain pump assembly that moves wash water out of the tub through the drain hose and into the household plumbing. The assembly consists of a small electric motor, an impellerand seals/mounting interfaces; failure modes include impeller blockage or breakage, bearing wear that causes binding, seal leakageor electrical failure of the motor windings. Compatibility is determined by the pump’s mounting flange, hose connectionsand connector type-mechanical fit and the electrical connector must match the washer model. Technicians should verify physical fit and connector pinout before replacementand confirm that replacement pumps are specified for the same nominal supply (for many U.S. models this is mains 120 VAC) and have matching hose diameters and mounting boss locations.
- No drain / water remaining in the tub after a drain cycle
- Pump motor hums but impeller does not turn
- unusual grinding or rattling noises during drain
- Visible leakage at pump seals or hose connections
- Machine trips a circuit breaker or control shows error codes related to draining
Diagnosis combines visual inspection, simple mechanical checksand electrical tests. Start by removing the pump to inspect for debris, broken impeller blades, and free rotation by hand-an impeller that spins freely when disconnected but refuses to run under power usually indicates electrical or control faults. Use a multimeter to check continuity across the motor leads; a winding open circuit shows as infinite resistance and indicates a failed motor, whereas low resistance (typically single to low hundreds of ohms depending on motor type) indicates continuity. While operating a drain cycle, measure voltage at the pump connector: for many Frigidaire machines this should be approximately 120 VAC at the commanded drain interval-presence of voltage with no impeller movement implies a mechanical seizure, whereas no voltage points to controls, timersor wiring faults. If the pump hums and draws excessive current, the motor is likely mechanically loaded or the bearings are failing; a current clamp can confirm high current draw under load.
| item | description |
|---|---|
| Continuity test | Multimeter between motor leads: open = failed winding; low ohms = winding intact |
| Supply voltage | Measure at connector during drain command: ~120 VAC (U.S.) expected; no voltage indicates control/wiring fault |
| Mechanical inspection | Remove debris, check impeller spin by hand; seizure or broken blades require pump replacement |
Compatibility, Replacement Considerations, Installation Stepsand Troubleshooting Procedures
Mechanical and electrical compatibility determine whether a replacement will function correctly in a given washer. The 137311900 Frigidaire Washer Pump must match the sump mounting pattern, inlet/outlet hose diametersand the electrical connector and supply voltage used by the machine; mismatches in any of these areas can cause poor fit, leaksor incorrect hydraulic performance. Verify that the pump’s outlet orientation and hose barb size allow the original routing without undue bends or strain, confirm that mounting tabs and screw locations align with the sump or bracketand ensure the replacement motor has the same nominal voltage and control interface (direct mains, triac-driven, or relay-switched) as the original. Aftermarket units sometimes use different impeller geometries or tolerances that change flow rate and backpressure; when exact OEM performance is required, prefer an OEM-number match or an explicit cross-reference rather than assuming physical similarity is sufficient.
Disconnect power and follow safe electrical work practices before starting work. Typical installation steps are: remove access panels, document and label wiring and hose routing, relieve and remove hoses and clamps, unfasten pump mount screws, swap the pump while replacing seals/clampsand reassemble in reverse order while checking sealing surfaces and clamp positions. For troubleshooting, measure supply voltage at the pump connector and motor winding continuity with a multimeter, inspect the impeller and inlet for debris or collapsed hosesand observe motor behavior (silent, humming, intermittent run) to narrow failures to electrical, mechanical obstructionor hydraulic restriction. Practical checks include applying the washer’s drain diagnostic cycle to isolate control-board versus pump failures, bench-measuring motor winding resistance to confirm an open or shorted windingand visually inspecting gaskets and hose clamps for signs of wear or compression that cause leaks; document part numbers and take reference photos to ensure the replacement maintains original routing and sealing integrity.
- Symptoms and quick checks: humming/no spin → check voltage at connector and for blocked impeller; no power → verify control board output and fuses; leaks → inspect gasket, hose IDand clamp seating; intermittent run → check wiring harness and board outputs.
- Installation reminders: label connectors,replace clamps and gaskets,reuse pump mounting hardware only if undamaged,and verify outlet orientation before tightening hose clamps.
