Function and Role â¤ofâ theâ Frigidaire Washer Drain Pump in Water Removal and Flow Control
The primary⤠function of the 137311900 Frigidaire Washer Pump is to evacuate wash and rinse water⤠from the tub âand force it thru the drain hose to the household plumbing. âThis component is a sealedâ motor-and-impeller â˘assemblyâ designed to run on the appliance’s AC âsupply and to⤠deliver⣠a relatively high volumetric flow atâ low head for short intervals during the wash cycle. âIn operation the pump âis âenergisedâ by the washer’s electronic control or⢠timer only⤠during drain or âintermittentâ purge âoperations; hydraulic design choices such as impeller âŁsize, volute geometryand any integrated check valve determine how quickly the tub âŁemptiesâ and how âthe pump responds to partial restrictions or âŁvertical liftâ in the drain run. Technician observations such as a humming motor with no⢠fluid movement, slow drain, âŁor foreign-object debris caught in the⤠inlet are consistent with worn â˘or obstructed pumpâ components rather than control-system faults in many cases.
The pump also plays a central⤠role in flow controlâ within the machine’s waterâ management system by working in concert with the water-level⢠sensor andâ the control electronics: the â¤controller energises the⤠pump until sensors report that the âŁtarget drainâ level is reached,so pump hydraulic⣠performance (flow vs. head) directly⤠affects â˘cycle timing âŁand spin â¤behavior. âPractical compatibility checks forâ replacement include verifying the electrical connector pinout, âmounting flange and seal dimensionsand rotational direction of the â˘impeller;⣠measuring theâ motor âwinding â˘resistance with a multimeter⢠and confirming free impeller ârotation are fast functionalâ tests before â˘installation.Typical service symptoms, diagnostic checks,â and a short âtechnical reference are provided below âtoâ aid repair decisions.
- Common⤠symptoms:â no drain but motor hums, â˘intermittent draining, audible grinding âor rattling, leaks at pump housingor high current draw.
- Basic checks: inspect⢠inlet screen forâ debris, âverify connector voltage âŁduring drain command, measure winding resistance, â˘and confirm âŁcorrect mechanical fitment.

How âthe 137311900 Frigidaire Washer Pump⣠Operates Inside the Appliance: Mechanical, Electricaland⣠Hydraulic Interaction
The 137311900 Frigidaire Washer Pump is a compact centrifugal⢠drain pump assembly âŁthat âcouples a small electric motor to a â˘molded impeller and housing. Mechanically it mounts â˘to the washerâ tub and⣠connectsâ to the drain hose; the impeller convertsâ motor torque intoâ fluid flow and⣠pressure required to evacuate the âwash tub during âdrain âand spin phases. Electrically the⢠pump receives switched supply â¤from the âwasher control board (often through a harness⤠and connector)⢠and will âŁrun onlyâ when the controller energizes the âappropriate circuit, so correct connector⣠orientation âand matching âcoil voltage are required for⣠compatibility.In practise, techniciansâ verify fit by matching⢠mounting tabs, hose diameter, âŁand âŁconnector pinout ratherâ than relyingâ solely on model numbers, asâ several Frigidaire model series use similar pumpâ assemblies with slight variations in outlet orientation or harness length.
Inside the appliance theâ pump’s mechanical, electricaland hydraulic subsystems interact continuously: the motorâ provides rotational â¤energy, theâ impeller imposes a centrifugal⣠pressure head that overcomes static water âŁlevel and discharge backpressureand the housing and hoses defineâ flow restrictions and⢠leakage paths. âŁCommon failure modes illustrate these interactions – âa seized impeller orâ blocked inletâ reduces flow⢠despite motor⤠voltage, worn motor bearings⤠or âŁbrush wear produces⤠noise and reduced RPM, âŁand a split seal âor cracked housing causes leaks even if theâ motor runs.â Replacing the pump typicallyâ resolves symptoms such âas no drain, weak flow, humming without rotationor visible leakage, butâ verification with a multimeter, inspection ofâ the discharge hose andâ check â˘valveand confirmation ofâ control-board output will identify weather the fault is mechanical, electricalor hydraulic before replacement.
- No drain or slow drain: possible impeller clogâ or⢠hydraulic restriction.
- Humming but no⤠spin: electrical rotor stall,⢠seized bearingsor jammed debris.
- Leaking at pump housing or seals: mechanical seal failure or⢠crackedâ housing.
- Intermittentâ operation: wiring harness, connector corrosionor control output⣠issue.

Common failure Symptoms and Diagnosticâ Tests for Pumpâ Motor, Impeller,â and Seals
The 137311900 Frigidaire⣠Washer Pump is a combined motor-and-impeller assembly that evacuates⢠wash âwater through the â˘drain system â¤while relying on a shaftâ seal to keep fluids awayâ from the motor windings. âIn normal operation the motor⢠produces sufficientâ torque to⤠spin the impeller against hydraulic and debris load; failures typically present as loss of flow, âunusual noise, humming without rotationorâ external leakageâ whereâ the seal or âhousing has been compromised. Because the âŁpump is an integrated mechanical and â˘electrical component,compatibility is dictated by mountingâ points,connector âŁtype,and seal â¤orientation rather than cosmetic â¤appearance-replacement units must match these interfaces â˘to ensure proper⢠fit andâ reliableâ shaft sealing under load. Practical examples include a⣠trapped sock that reduces flow and increases âŁmotor current, âŁor a failed seal âthat allows water intrusion âand âprogressive winding damage.
Technicians diagnose pump problems through a combination of visual, mechanical and electrical checks.First, visually inspect the housing âand âimpeller for foreign objects and evidence â¤of leaks; manually confirm the impeller rotates freely and without⤠axial play. For âelectrical verification, disconnect power before accessing wiring, then measure continuity across the motor terminals (shoudlâ show a closedâ winding) and insulation to chassis (should be open/no continuity). âDuring a controlled drain cycleâ measure voltage at the pump connector (nominally ~120 VAC on most U.S. machines) âŁand compare motor current to service data-a hum â¤with low/no rotation typically indicates mechanical binding or a âseized âimpeller, while normal rotation⢠with low flow points to â¤impeller âdamage⤠or partial blockage.If the pump passes â˘bench electrical tests but leaks or noise âŁpersist, replace the assembly to restore⤠reliable âsealing and hydraulic performance.
- No drain: â˘inspect for obstructions, confirm voltage at connector, verify continuity of motor windings.
- Humming without âspin: check impeller for jams,measure motor â˘current for overload,confirm shaft⤠turns⤠freely by hand.
- Intermittent operation:⣠inspect âwiring harness âand connectors, test switch/relay operation that suppliesâ the âpump.
- External leakage: examine shaft seal and housing for cracks or coolant tracks; replace pump ifâ seal integrity⤠is âlost.
- Excessive⢠noise âor vibration:â look for debris trapped against the impeller, worn bearingsor bentâ impeller blades.
| Item | Description |
|---|---|
| Continuity test | Closed winding between â¤motor terminals; no continuity between â¤windings and chassis (no short to ground). |
| Voltage âŁcheck | Measure supply at connectorâ during drain command (nominallyâ ~120â VAC on âU.S. models)⤠to⤠isolate control vs. â¤pump failure. |
| Impeller spin | Impeller âŁshould rotate âsmoothly by hand; binding indicates obstruction or bearing⢠failure⢠causing high current draw. |
| Leak inspection | Visual check for â˘coolant/water at the pump seam âor shaft; wetness at motor indicates seal failure and likely replacement. |
