137311900 Frigidaire Washer Pump is a motor-driven drain pump assembly designed for use in residential washing machines. The component typically consists of a small electric motor coupled to a plastic or metal impeller and a molded pump housing with inlet and outlet ports; in practice it is categorized as a centrifugal drain pump that evacuates wash and rinse water from the tub during the drain and spin portions of the cycle.
Inside the appliance the pump’s primary role is to move wastewater from the tub through the drain hose and into the household plumbing or a laundry standpipe. It functions as part of the washer’s hydraulic and control subsystems,receiving power and run commands from the main control board and working in concert with the tub,drain hose,pressure/water-level sensing,and inlet/drain plumbing. The pump is usually mounted at the lower section of the cabinet and is integral to completing wash cycles, preventing standing waterand protecting against overflows or flooding when operating correctly.
This article will explain the pump’s operating principles and expected electrical/ mechanical characteristics, outline compatibility considerations and how to verify that 137311900 is the correct replacement for a given modeland describe common failure symptoms such as no-drain conditions, unusual noise, leaks, or control error codes. It will also cover diagnostic approaches appropriate for technicians and informed owners (visual inspection, basic electrical checksand obstruction testing)and summarize replacement considerations including sealing interfaces, electrical connectors, mounting orientationand safety precautions to observe during removal and installation.

Function and Role of the Washer Drain Pump Assembly in Frigidaire Laundry Appliances
The drain pump assembly is the mechanical component that removes wash and rinse water from the tub and forces it through the drain hose; the 137311900 Frigidaire Washer Pump is an OEM-style replacement that mounts to the washer’s base and couples an electric motor to a centrifugal impeller. When the machine’s control board calls for a drain or spin phase,it supplies voltage to the pump motor which generates flow and discharge pressure; the pump housing,impeller orientation,and outlet port location determine the achievable head and the hose routing. Manny pump assemblies include an internal thermal protector and a one-way check function or valve in the housing to reduce backflow during spin cycles and to protect the motor from short-duration overloads.
- Symptoms of pump-related faults: slow or no draining, humming without water movement, grinding or rattling noises, and water remaining after cycle completion.
- Compatibility checkpoints: confirm electrical connector/pinout, mounting hole pattern, inlet/outlet orientation, and physical clearance before replacing.
- Common maintenance items: clear foreign objects from the impeller area, inspect and clean the drain hose and lint trapand verify control-board drive voltage during a drain call.
Technicians diagnose pump failures by observing mechanical behavior and verifying electrical inputs: measure for continuity across the pump motor windings, check for the presence of correct supply voltage during a drain commandand inspect the impeller for blockage or damage.Practical replacement decisions hinge on matching the replacement part’s mechanical interface and electrical characteristics to the original unit; swapping in the 137311900 Frigidaire Washer Pump without confirming connector type or mounting orientation can result in fitment issues or improper drainage. In field repairs, common corrective actions include removing trapped debris, replacing a seized impeller or worn motorand confirming proper hose slope and clamp integrity to restore reliable drainage.

How the 137311900 Frigidaire Washer Pump Integrates with the Drain, Motor and Control Systems
The 137311900 Frigidaire Washer Pump is a self-contained pump assembly that combines an impeller and a dedicated pump motor in a single unit and mounts to the washer’s tub or chassis to evacuate wash water through the drain hose. Electrically,the pump interfaces with the washer’s control board via a multi-pin harness so the control board supplies power to the pump motor only during drain and certain spin phases. Mechanically the assembly aligns with the drain outlet and uses OEM mounting tabs and hose fittings to maintain sealing and correct flow direction; mismatched orientation or worn gaskets will reduce flow or allow leaks. In normal operation the control board sequences the tub motor and pump-first the wash basket slows/drains, then the pump runs to clear water; pump run duration and any retry logic are handled by the control firmware based on water-level and flow feedback from sensors or pressure switches.
- Common symptoms indicating pump or integration issues: no water removal with pump power absent, pump hums but no flow (impeller jammed), intermittent draining (wiring or control relay fault), backflow due to missing/check valve failure.
- Service checks: verify harness continuity,observe connector voltage during an active drain cycle,inspect and clear the impeller and inlet screen,and confirm proper hose routing and clamp tightness.
Practical troubleshooting differentiates electrical faults from hydraulic restrictions: a multimeter reading across the pump connector while the control calls for drain confirms whether the control and wiring are delivering power; if voltage is present but the pump dose not turn, the fault is mechanical or in the pump motor windings. Replacement with a compatible 137311900 assembly restores the designed mechanical fit and connector pinout on compatible Frigidaire models, but technicians should confirm model-level compatibility and verify mounting screws, gasket conditionand hose diameter to ensure proper sealing and flow. For preventive service, clear foreign debris from the pump inlet, check the drain hose for kinksand test pump run time against the service manual values to detect slow-performance degradation.

|---|---|
| Electrical interface | Multi-pin harness to control board; control provides power during drain/spin phases-verify voltage at connector for diagnostics |
| Mechanical interface | Mounting tabs, inlet/outlet hose fittings and gaskets that align with tub/drain; orientation affects flow and sealing |
| Functional role | Evacuates wash water to drain; coordinated by control logic with basket motor and water-level sensors |
Common Failure Symptoms and Diagnostic Tests for Mechanical, Electrical and Flow Issues
The 137311900 Frigidaire Washer Pump is a motor-driven drain pump assembly that evacuates tub water through the drain hose and provides brief agitation of flow during certain cycles. Failures typically manifest as hydraulic (clogged impeller or housing), mechanical (worn bearings, seized impeller)or electrical (open windings, failed start capacitor/thermal cutout, or damaged connector) faults; compatibility during replacement depends on matching the pump housing orientation, mounting tabsand electrical connector type to the washer model. For practical troubleshooting,verify whether the symptom is isolated to the pump or mimicked by a blocked hose or pump inlet screen – a model-specific replacement like the 137311900 fits only when those mechanical and connector characteristics match the machine chassis and control signals.
- No drain or very slow drain – check for debris in the impeller and inlet,then confirm motor winding continuity with a multimeter; if windings read open,replace the pump.
- Humming or noisy operation – manually spin the impeller; a seized or rough bearing indicates mechanical replacement, while a free-turning impeller with hum suggests control or voltage issues.
- Intermittent operation – probe for drive voltage at the pump connector during a drain command (measure only with safe test procedures); presence of voltage with no motor response points to a failed motor, absence of voltage implicates the control or wiring).
- Water leaking at the pump body – inspect seals and housing for cracks and verify correct seating of the pump on the tub; replace the assembly if the housing is cracked or seals are compromised.
Diagnose in a logical order: isolate hydraulic restrictions first,confirm the impeller turns freely,perform a continuity check of the motor windings,and then verify that the control board supplies the correct drive signal during drain cycles. Use a clamp meter or voltage probe at the pump connector to determine whether faults are electrical (no drive), mechanical (no-turn or binding under power)or external (blockage, kinked hoseor foreign object in the pump). Such as, if the impeller spins freely by hand and windings show continuity but no voltage is present during a drain command, the likely fault is the control board or harness rather than the pump itself; conversely, applied voltage with no rotation or with a grinding noise typically requires pump replacement.

|---|---|
| Impeller free-spin | Manual spin test to detect seized bearings or debris-induced binding. |
| Winding continuity | Multimeter check for open or shorted motor windings; open indicates motor failure. |
Compatibility, replacement Considerations and Step-by-Step Installation Procedures
The 137311900 Frigidaire Washer Pump serves as the drained-water expulsion device that transfers wash and rinse water from the tub to the household drain. It is indeed an electromechanical centrifugal pump whose compatibility with a given Frigidaire model depends on mechanical mounting points, inlet/outlet hose diametersand the appliance’s line-voltage and connector standards (commonly 120 VAC in North American units). Replacement considerations include matching the pump housing flange and screw pattern, rotor/impeller clearanceand electrical connector style; installing a pump with different shaft orientation or mismatched hose fittings can create leaks, strain on the motoror improper sealing. Technicians should cross-reference model numbers and verify that the replacement pump provides equivalent flow and clearance to avoid interference with the tub or drain hose routing.
- Verify washer model number and OEM cross-reference before purchase.
- Disconnect power and isolate water supply; remove residual water from the tub using a manual siphon or low pan.
- Document wiring and hose locations (photo or labels) before disassembly.
- Inspect electrical connector type and measure continuity of the old pump motor to confirm failure.
