Function and Operational Role of the Washer âPump in Water Removal and Recirculation
The 137311900 Frigidaire Washer âPump is⣠the pump assembly used to âremove âwash and rinse water â¤from the tub and⣠to⣠support limited recirculation functions within the washer. It consists of a smallâ electric motor coupled to a molded impeller and housing with inlet(s) for tub drainage and an outletâ for the discharge hose; the washer’s control board or timer supplies âvoltage to the pump motor during drain and selected recirculation intervals. âŁHydraulic⢠characteristics of the impeller and housing⤠determine flow rate and tolerance to backpressure, so correct mechanical⢠fit â¤(mounting tabs, port orientation) and matching electrical connector are required for reliable replacement and compatibility with specific Frigidaire models.
In operation the âpump runs during drainâ and certain wash/rinse cycles âto move water from the tub to the household⣠drain or to recirculate water through the washer’sâ rinse/soak paths. Typical failure modes areâ mechanical obstruction⣠(coins, lint, fabric debris), worn bearings or impeller damage causing reduced flow⤠or ânoiseand electrical faults âin the motor windings or connector that⣠prevent startup. Troubleshooting usually involves confirming the control sends voltage during the drainâ command, inspecting the inlet/discharge hoses and â¤pump inlet for blockages,â checking motor continuityand verifying that checkâ valves and drain routing are âcorrect. Practical technician checks and preventive âŁmaintenance âŁ- clearing debris from the pump housing and⢠ensuring the discharge hose is free of kinks â¤- often ârestore proper â¤function without full replacement.
- No or slow drain duringâ spin or drainâ cycles
- Humming motor with littleâ or no water movement (impeller jammed)
- Loud mechanical noise indicatingâ bearing or⢠impeller damage
- Leaks at pump housing or hose connections

How âthe 137311900â Frigidaire Washer⣠Pump Works: Motor Assembly, Impeller Dynamicsand Electrical Interfaces
The 137311900 Frigidaire âWasher Pump is⤠an integrated motor-and-impeller assembly that âevacuates wash water by â˘converting electrical energy into â¤centrifugal fluid⢠flow. The motor section contains the stator, rotor/armature and shaft, â˘along with bearings and a shaft seal thatâ prevents tub water from entering the windings. The impeller is âŁmolded to the pump shaft so rotational speed⤠directly controls flow rateâ and head; any lock-upâ of the impeller from debris or â˘a âdamaged bearing will reduce flow and â˘increase motor current. Common mechanical failure âŁmodes are clogged impeller vanes, â¤worn â˘bearings âthat cause excessive axial or radial âplayand a degraded⣠shaft seal that leads â˘to leaks; these behaviors are useful diagnostic clues when assessing a failing unit in the field.
The pump interfaces â¤electrically âthrough a simpleâ harness-typically a twoâterminal power connection with a chassis ground-while âsome washerâ control systems include thermal protection or current-sensingâ circuits to detect stalls. When⣠troubleshooting, confirm that the control sends line voltage to âthe âpump⤠during the drain step, measure âŁwindingâ resistance â¤forâ an open or shorted motor, âand check runningâ current againstâ manufacturer rangesâ to detect bearing drag.For replacement or retrofit, verify connector type, âmounting orientation and the pump’s rated voltageâ to⢠ensure compatibility; mismatched voltage or reversed plumbing can â¤prevent proper drainage or overload the motor, so always match electrical and⢠hydraulic characteristics before⢠installation.
- Symptoms: âhumming âŁwithout flow, intermittent operation, excessive ânoise, leakageor high â˘amp draw.
- Common checks: voltage at âconnector during drain,â continuity â¤ofâ motor windings, visual âŁinspection for⤠debrisand shaft âplay.

Commonâ Failure Symptoms and Diagnostic Tests forâ Pump Blockage, Seal Failureand Motor Faults
The â¤137311900 Frigidaire Washer Pump is âthe electromechanical component that evacuates wash⤠and rinse water⤠from âthe tub through the drain system. â¤Functionally it combines a small âAC motor and an impeller inside a molded housing with âa mechanical seal between the â˘wetâ and dryâ sections; when âŁthe impeller is obstructed by foreign objects or the seal has failed, the pump will exhibit characteristic behaviors such as reduced flow, external leakage,⣠orâ unusual noise. Compatibility is primarily with â˘specified âŁFrigidaire âwasher models thatâ use âthe same mounting⢠flange, hoseâ diameters, âŁand electrical connector; when replacing the⤠part, confirm the housing⣠orientation and connector pinout to ensure correct â˘fit â˘and rotation direction for effective drainage.
Diagnosing â¤blockage, seal failureand motor faults relies on a sequence of visual,⤠mechanicaland electrical checks. Startâ with âa visual inspection â˘and removal of inlet/outlet hoses to confirm foreign â˘objects (coins, buttons, lint) and test that the impeller rotates freely by hand; a humming motor with no rotation usually indicates an internal jam âor seized bearings. Electrical tests include measuring supply voltage at the pump connector during aâ drain cycle, checking motor âcoil continuity and cold resistance âwith a multimeterand recording running current with a clamp âmeter to detect bearing â¤drag or winding shorts. Practical examples:⤠a coin âlodgedâ between the impeller and housing will cause a humming sound and zero flow;â aâ split elastomeric seal typically producesâ aâ steady drip at the pump seam and â¤can permit water to reach the motor,changing resistance readings; overheated âwindings often yield open orâ very low resistance and a burnt odor.
- Washer won’t⤠drain⤠but pump hums:â likely impeller â˘blockage or seized bearing â- remove⤠hoses and inspect pump housing for debris.
- Visible leak at pump seam or â˘around âhose: probable seal failure – inspect âŁfor water intrusion on motor and replace pump assembly âif motor contamination â¤is present.
- Pump silent and no rotation: check 120âŻVAC at connector during drain command; ifâ voltage present, â˘suspect motor failure.
- High running current orâ grinding noise: bearing wear or rotor contact – measure current under load and compareâ to expected range.
- Intermittent operation: check connector âterminals andâ wiring for corrosion or loose connections before âŁreplacing the pump motor.
| Item | Description |
|---|---|
| Supply voltage | Typically 120âŻVAC at the pump connector during⢠drain cycle⢠(verify per model). |
| Typical â¤running current | Approximately 0.6-1.5âŻA under normal âload; âconsiderablyâ higher indicates âmechanical⢠drag. |
| Approximate coil resistance | Cold resistance often in the tens â˘of ohms⤠range; an open circuit suggests winding failure. |
| Connector / mounting | Model-specific spade or âplug connector âand flange âmounting-confirm âŁpinout and rotation before installation. |
