Function and Role of the Washer Drain Pump â˘in Frigidaire⢠Laundry Systems
Theâ 137221600 âFrigidaire âWasherâ Drain Pump is a motor-driven impeller assembly⤠responsible for evacuating wash and rinse water from the â˘tub to the household drain during â¤the⢠washer’s drain âand â˘spin cycles. It converts electrical energy âŁfrom the machine control board into axial flow through a âŁmolded plastic impeller and housing, producing the head and flow required to overcome drain hose elevation and⢠partial restrictions such⢠as trap bends or lint screens.â Mechanically, the pump âis âŁmounted to the washer base or âtub outlet with engineered tabs and seals; electrically it âtypically connects via a multi-pin harness and is designed âto meet the appliance’s nominal voltage and â¤duty-cycle requirements for repeated short-duration operation during a wash â¤program.
In service,the pump’s âbehavior gives clear diagnostic signals: complete failure to evacuate,slowed drainage extending cycle time,a humming motor when the impeller is jammed,or visible leakageâ from the housing orâ shaft⢠seal. Technicians should verify supply voltage at the harness, check forâ foreign objects in the âimpeller and inletand measure motor âŁwinding continuity before replacing the unit. When âordering a replacement, confirmâ the 137221600 Frigidaire â˘Washer â¤Drain Pump matches the â˘washer model’s mounting configuration, connector â¤typeand electrical rating to ensure⣠compatibility and safe⣠operation; mismatched âmechanical fit âor electrical characteristics can produce poorâ drainage or premature failure.
- No drainage or extended drain time âŁ(pump fails to move water).
- audible humming or grinding âindicating a jammed impeller or⣠worn bearings.
- Visible⣠leakage at pump housing or âshaftâ seal indicating a failedâ gasket or crack.
- intermittent⤠operation caused by electrical connector faults or thermal overload trips.

Internal Designâ and⣠Operation of the 137221600 Frigidaire âWasher â˘Drain âPump Inside the Appliance
The 137221600â Frigidaire Washer Drain Pump âŁis anâ electromechanical assembly responsible for⣠evacuating âwash water from the tub during the drain and spin cycles. It consists⣠of a⤠compact motor driving â˘a molded impeller inside a pump housing,and it is indeed designed to integrate with the â˘washer’s drain plumbing âŁand electricalâ harness. In compatible Frigidaire models the pump operates intermittently under control⢠of the âmachine’s main control board; the⢠board supplies line voltage to the pump only during drain âŁevents and may monitor current âdraw to âdetect stalled conditions.â Technicians will commonly encounter this pump when diagnosing slow⤠drains, hum/no-spin symptomsor leak points at the pump housingâ or hose connections.
Internally the pump â¤combines a small âsynchronousâ or shaded-pole⣠AC motor â¤with â¤a molded plastic â¤or composite impeller, a shaft bearing/seal assemblyand an outlet port integrated into the housing. Important functional â˘elements include a âlow-clearance impeller geometry⣠for reliableâ priming, a sealed motor end to resist moisture, âŁand often⢠a thermal overload protector⢠embedded in the windings. Typical failure modes are mechanical blockage⤠ofâ the impeller by lint âor foreign objects, worn âŁseals causing leaksor electrical⢠faults⤠such as an â¤openâ winding; these failures manifest as reduced âflow, continuous humming⢠without pumpingor complete electrical open-circuit.⣠Practical diagnostic checks include âverifying supply voltage at â¤the pump connector, âmeasuring motor winding continuityand visuallyâ inspecting the impeller and strainer; replacement is warranted when the⤠shaft seal leaks or the motor fails electrically.

Diagnostic Indicators and Common Failure âŁModes of the Drain Pump Assembly
The 137221600 Frigidaire Washer Drain Pump âŁis âan electromechanical assembly that removes â˘water from the wash tub by âusing aâ small motor-driven impellerâ and a sealed housing with inlet and outlet connections. In⤠normal â˘operation the motor⢠provides sufficient torque to overcome the washer’s âdrainâ head and common resistance from the drain⣠hose; âmechanical issues âsuch âas damaged impeller âŁblades,⣠foreign-object â¤jams (coins, small articles,⢠compacted lint) or bearing wearâ reduce flow and increase current draw.Compatibilityâ for replacement depends on matching the pump’s mountingâ flange,electrical connector and outlet/hose âdiameter to the washer model-confirm âthe washer’s⣠model number andâ compare the harness and mounting points before installation to ensure correct fit and sealing â˘behavior under load.
- No drain or long⢠drain cycles: pump does not âŁrun or spins without âproducing flow (broken impeller orâ internal⣠clog).
- Humming or high current draw: motor⤠energized but impeller⣠stalled â¤or bearings seized.
- Intermittent operation: âwiring harness corrosion or intermittent motor contact.
- Loud grinding or rattling: debris contacting impeller or damaged bearings.
- visible leaks â˘at the housing or seals: failed pump â¤seal or⣠crackedâ housing.
| Item | Description |
|---|---|
| impeller free-spin | should rotate freely by hand; resistance or binding indicates âjammed debris or bearing failure. |
| Motor continuity | Test with a â¤multimeter for continuity⤠across windings; an open circuit indicatesâ a âfailed motor winding. |
Diagnostics combine visual⤠inspection with⣠electrical tests: disconnect mains power, remove the pump âand check the inlet for âtrapped debris,⢠manually rotate the impeller to confirm free motionand inspect the housing for cracks or worn seals. For electrical verification, use a âŁmultimeter to check for continuity and âŁreasonable â¤resistance across the motor â˘leads (absence of continuity or aâ short to ground indicatesâ replacement); a qualified technician â˘can apply the manufacturerâspecified supply voltage on⢠a bench⤠toâ confirm âmechanical pumping under controlled conditions.practical examples: a washer that hums butâ does ânot evacuate typically has a jammed impeller or collapsed hose, while a pump that âruns but produces no flow often has stripped impeller blades or âa disconnected outlet hose-addressing the specific mode (mechanical obstruction versus â¤electrical failure) determines whether cleaning, seal replacementor a full 137221600 Frigidaire Washer Drain Pump replacement is required.
Compatibility, Replacement⤠Requirements,⣠and Installation Procedures with Troubleshooting for Affected Frigidaire Models
The â 137221600 Frigidaire Washer Drain âPump âŁis the electromechanical component that evacuates wash water from the tub to the⢠household drain. Functionally it is a small âsingleâspeed pump with an impeller and a twoâwire power connection; compatibility depends onâ physical mounting, âinlet/outlet hose diameterand electrical connector âtypeâ rather than⢠model âŁyear alone. Technicians should verify the washer model and compare theâ pump⢠mounting ear spacing, hose barb sizeand⤠connector pin geometry against the⢠replacement⣠unit or âOEMâ parts diagram; aâ pump that⤠matches âŁelectricalâ and mechanical â¤interfaces⤠will typicallyâ installâ without âmodification. Confirm the pump housing seals and the retaining grommet are⤠included or replaced to prevent leaksâ after installation.
Replacement and installation require safe isolation of electrical power,⤠draining residual⣠water,⤠and careful âdisconnection of the inlet/outlet hoses and⣠wiring harness. Install the new pump in the same orientation, secure mounting tabs,â reconnect âhoses with clamps sized to⢠the pump barband restore power only after the assembly is dry; run a short â˘drain cycle⤠to⤠confirm flow and absenceâ of leaks. If theâ washer â¤failsâ to drain, check these items first: fuse/circuit, wiring continuityâ to the pump, presence of 120 VAC at theâ connector during a drain cycle,⣠and whether theâ impeller is âobstructed by debris. Common troubleshooting symptoms and checks are summarized below.
- Humsâ but no water movement: inspect⤠impeller for jammed debris; verify supply voltage to the pump âŁduring drain âcommand.
- No continuity on multimeter:â replace âpump motor windings are open.

Q&A
What is⢠the⢠frigidaire washer drain pump part 137221600 and what does it do?
The 137221600 is the OEM âdrain pump assembly used on a numberâ of âFrigidaire / Electrolux âtopâ âŁand frontâload âwashers. Its âŁjob is to remove wash/rinse water from the tub by pumping it out through⣠the drainâ hose⤠into your household drainâ during the drain and spin portions âŁof the cycle.The assembly typically includesâ the âpump motor and⣠impeller and attaches to the⤠washer’s drain hose and plumbing.
What are the commonâ symptoms that indicate the 137221600 drain pump is failing?
Typical failure symptoms include: washerâ won’t âdrain âor âdrains⢠vrey⢠slowly, standing water âin the tub after the cycle, loud grinding or â˘rattling noises during drain, an intermittent⢠drain⤠whereâ sometimes â¤it effectively âworks and sometimes notand visible leaks coming from the pump area. Some⢠failures are caused by foreign objects blocking the impeller rather than motor âfailure,so check for âdebris â¤first.
How âdo â˘I diagnose whetherâ theâ pump⣠(137221600) is bad or if âŁthe problem is âelsewhere?
Start with âŁmechanical checks: unplugâ the washer,⢠drain residual water, remove the âpump access panel and⤠inspect the impeller and inlet/outlet for debris (coins, small â¤items, lint). check â˘hoses for clogs or kinks. Electrically, with the washer âunplugged remove the pump connector and check for âcontinuity across⣠the motor terminals with a multimeter – a functional motor will show low resistance (not infinite). âDuring a drain⢠cycle you can measure if the pump âŁis receiving supply voltage (typically 120 VAC on U.S. models) – if it has supply voltage but does not run, the pump motor is likely bad. If it has noâ voltage, the fault couldâ be in âŁtheâ timer/control, â˘door/lid switch, pressure switchor wiring.
Can I runâ the pumpâ directly to test it,and if⢠so how? Is it safe?
you can benchâtest a pump by applying the correct supply voltage,butâ this should only be done by someone experienced with⢠mains voltage. For most âU.S. washers the pump is driven âby â120 VAC – confirm with theâ service manual or by measuring at the connector before⣠applying power. If you decide to benchâtest, remove the pump from the washer, secure it so â¤it won’t⤠move,â and briefly apply voltage while keeping hands and tools clear⢠of the impeller. A safer alternative is to energize the pump whileâ it’s still⤠connected in the machine and run â¤a⣠diagnostic or drain cycle âso protective interlocks remain⢠engaged. Always unplug the âappliance before any disassembly and follow electrical â¤safety procedures.
Howâ do I replace âŁthe 137221600 drain pump? What tools âand steps areâ required?
Replacement is âŁa moderate DIY job. Typical steps: unplug⢠the washer, shut off âŁwater, drain any remaining âŁwater, removeâ the lower access panel (or tilt washer per⣠model instructions), locate the âpump, disconnect the electrical connector(s), remove â¤the â¤clamps âand disconnect the inlet/outlet hoses (have towels and a shallow pan ready), unbolt or unclip the pump assembly, swap â¤the old pump for the new one (transfer any mounting brackets or grommets if needed), reconnect hoses with new or tight clamps, reconnect electrical plug, âreassemble panels and test with a short drain cycle.⣠Common tools: â˘screwdrivers, pliers for clamp removal, socket âŁset, towels. Follow the model’s service manual for specifics and safety steps.
Will replacing the pump always fix a noâdrain problem? What else should I âŁcheck?
No – a failed pump is a common cause â¤but not the only causeâ of noâdrain issues.Check âŁfor clogged drain hoses, clogged or faulty pump filters/coinâ traps, a malfunctioning lid/door âŁlock or pressure switch, blocked drain âline/household trapand control/timer problems. If the pumpâ hums but doesn’t â˘move water, inspect for debrisâ jammedâ in⤠the impeller. If the pump is gettingâ voltage andâ is not running,⣠replacing it is appropriate; if⤠it’s not getting⤠voltage, diagnose the control or safety interlocks.
How do I âknow if the pump is leaking and should I replace it or can it⢠be repaired?
A leaking â˘pump usually indicates a failed shaft seal or cracked housing; small⤠external leaks âmight potentially â¤be from loose hose clamps or â¤damaged hoses. Inspect âhose⢠connectionsâ and clamps first. If the leak⣠is from the pump body or motor shaft seal, replacement of âthe pump assembly is recommended – individual seal â¤repairs are âŁgenerally not costâeffective for â¤mostâ owners. Ensure hose⢠clamps areâ tight and hose endsâ are in âgood âcondition before replacing the pump.
