137221600 Frigidaire Washer Drain pump is an electric pump assembly used to evacuate wastewater from a washing machine tub.The component typically consists of a small motor,an integrated impeller and housing,and electrical and plumbing interfaces; it is a centrifugal-style drain pump that attaches to the washer’s drain outlet and connects to the drain hose and wiring harness.
Inside the appliance the drain pump’s role is to move water out of the tub during the drain and spin portions of the wash cycle and to do so under command from the machine’s control system. It interacts mechanically with the tub outlet, drain hose and any lint or debris trap, and electrically with the washer’s control board, relays/triacs and door/lock or water-level interlocks that sequence the pump operation. Proper function of the pump is required to complete drain cycles, allow effective spinning and prevent overfilling or standing water that can trigger fault codes or cause leaks.
In this article readers will find a technical review of the pump’s function and typical construction, guidance on compatibility and how to identify correct replacement units, common failure symptoms and the diagnostic checks a technician can perform (electrical continuity, voltage presence at the connector, and blockage inspection), and practical troubleshooting and replacement considerations such as matching inlet/outlet dimensions, connector pinout, mounting orientation and sealing. The following sections will provide step-by-step diagnostic logic and checklist items to help technicians, engineers and appliance owners evaluate and, when necesary, replace the unit safely and effectively.

Function and Role of the Drain Pump Within Frigidaire Washer Operation
The 137221600 frigidaire Washer Drain Pump is the electromechanical device responsible for removing wash and rinse water from the tub during the drain and spin portions of a cycle. The assembly sits in the washer sump and uses a small centrifugal impeller driven by an electric motor to move water into the drain hose; the pump is commanded by the washer’s control board or drain relay and frequently operates in tandem with the spin motor and water level/pressure sensor. Correct function depends on mechanical fit (mounting flange,hose diameter,and impeller clearance),electrical compatibility (matching connector,coil voltage and polarity),and proper integration with the washer’s drainage path and any one-way check valves to prevent backflow into the tub.
Technically, the pump’s behavior is deterministic: it receives a timed or sensor-triggered run signal, should start instantly and maintain steady flow until the control stops it or the water level reaches the target. Practical diagnostics include verifying that the control is supplying line voltage to the pump during the drain command and checking the motor for continuity or unusual resistance values, inspecting the impeller for debris or damage, and confirming that inlet/outlet hoses and clamps are clear. Noise, intermittent operation, or failure to evacuate water commonly point to obstructions, worn bearings, or electrical faults; replacement with a compatible unit that matches the original mounting, connector type, and voltage rating restores reliable operation.
- Common symptoms of pump issues: no drain, gurgling, excessive vibration/noise, or repeated drain attempts by the control.

How the 137221600 frigidaire Washer Drain Pump works Inside the Appliance
The 137221600 frigidaire Washer Drain Pump is a compact centrifugal pump assembly that evacuates wash and rinse water from the tub through the drain hose. Internally the part combines a small electric motor, an impeller, and a sealed plastic housing; the motor converts electrical energy into rotational torque and the impeller converts torque into fluid flow and pressure. The assembly also incorporates mounting interfaces, inlet/outlet ports and a sealed bearing or bushing system; these elements determine compatibility with a given washer chassis and influence serviceability and expected failure modes.
In operation the pump runs during the washer’s drain and spin sequences under command from the control board or timer and must overcome static head in the drain line to clear the tub within the allotted cycle time.Typical behaviors useful for diagnosis include a humming motor with little or no flow (mechanical blockage or seized bearings), audible free spinning with no water movement (impeller damage), and visible leaks at the housing or hose connections (seal failure). For replacement or troubleshooting, match the pump by physical mounting points, connector type, and hose diameter rather than by brand name alone; practical examples include clearing trapped lint or coins from the pump inlet to restore flow and using a multimeter to confirm the pump receives voltage during a drain command to isolate electrical faults from mechanical faults.
- No drain but motor hums - likely obstruction or seized rotor.
- Intermittent draining – possible intermittent electrical connection or foreign debris.
- Visible leak at pump housing – seal or cracked housing.
- Normal voltage present at connector but no rotation – motor failure.

| Service check | Listen for motor sound, inspect impeller for debris, check for applied voltage during drain cycle, and verify hose and sump clearances. |
Common Failure Symptoms and Diagnostic Indicators for the Washer Drain Pump
The 137221600 Frigidaire Washer Drain Pump serves to evacuate wash water from the tub through the drain hose and is a common service-replaceable component in Frigidaire laundry machines. Typical failure modes include electrical faults in the pump motor, mechanical blockage of the impeller, and housing leaks; each produces distinct diagnostic indicators. For example, a pump that hums but does not turn often indicates a seized impeller or worn motor brushes, while a pump that is electrically open on a continuity check points to burned windings. Technicians should observe both the electrical behavior during a drain cycle (voltage present at the pump connector) and the mechanical condition (impeller free-spinning, absence of foreign objects) to differentiate between control-system faults and a failing pump assembly.
- No water evacuation / clothes remain wet after spin - possible pump failure, clogged drain hose, or control/timer issue.
- Audible humming or grinding during drain – frequently enough impeller jammed by debris or bearings/brushes worn.
- Intermittent operation – may indicate intermittent wiring, poor connector contact, or thermal intermittency in the pump motor.
- Visible leak beneath washer or around pump housing – cracked housing or failed seal.
- Tripped breaker or blown fuse when pump runs - shorted motor windings or mechanical seizure causing overload.
| Item | Description |
|---|---|
| Continuity test | Continuity through pump motor indicates intact windings; an open circuit indicates winding failure and replacement. |
| Voltage at connector | 120 VAC (or model-specific supply) present during drain cycle indicates pump should be driven; absence points to control or wiring fault. |
| Mechanical inspection | Free-spinning impeller and clear inlet = electrical or control fault; seized or obstructed impeller = mechanical fault. |
Compatibility and practical repair decisions depend on observed symptoms and simple tests: if the pump shows proper supply voltage and continuity but fails to move water, inspect and clear the drain hose and pump inlet for debris before replacing the 137221600 Frigidaire Washer Drain Pump; if the pump draws excessive current, makes metal-on-metal noise, or shows an open winding, replacement is the likely remedy. Common field checks include measuring harness voltage during a drain command, performing a resistance check across the motor terminals, and visually confirming connector integrity and hose fitment; documenting these findings helps determine weather the issue is the pump itself, the control board, or an installation/hose problem. Strong service practice includes photographing wiring and hose routing before removal and verifying that replacement pumps match the original mounting points and electrical connectors.
Replacement Considerations and step-by-Step Installation Procedures
The 137221600 Frigidaire Washer Drain Pump is an electromechanical assembly that evacuates wash water from the tub through the drain hose; it consists of a small shaded‑pole or permanent‑split capacitor motor, an impeller molded into a plastic housing, and sealing interfaces where the pump meets the washer cabinet and hoses.Common failure behaviors include the pump motor humming without spinning (impeller jam or burned motor windings), visible leakage at the housing seams or gaskets (seal failure), and intermittent operation caused by corroded electrical connectors. When assessing replacement compatibility, verify the pump’s outlet orientation, mounting tab spacing, connector pin configuration, and hose inner diameter – a visually identical housing can still differ in connector type or flow orientation so compare the old unit directly or consult the washer’s parts diagram before ordering or fitting the new pump.
Follow a controlled replacement sequence and basic electrical checks to ensure reliable installation: disconnect power and close the water supply, remove the access panel, and drain residual water into a bucket before loosening hose clamps to avoid spills.After detaching the hoses and electrical plug, remove mounting fasteners, inspect and remove any debris or foreign objects from the pump inlet, and measure motor winding continuity with a multimeter; a very high or open reading indicates a failed motor.Transfer any required grommets or seals to the new unit, orient the outlet to match the original routing, torque the mounting screws to factory values, reconnect hoses with new clamps if corroded, restore wiring with clean contacts, and run a short drain cycle to verify proper flow and absence of leaks.
- Safety first: Disconnect power and place towels/bucket to catch water.
- Compare physical dimensions,connector pins,and outlet orientation before final installation.
- Test motor continuity prior to full reassembly; replace gaskets/clamps as needed.

Q&A
What is the Frigidaire part 137221600 and which machines use it?
137221600 is a replacement drain pump assembly used on a range of Frigidaire / Electrolux family washing machines. It is the electric pump that removes wash and rinse water from the tub and pushes it into the drain hose. Compatibility varies by model year and region-always confirm fit by checking the washer’s model number and the parts list or seller cross-reference before buying. The part number is stamped on the pump body; matching that to your washer’s parts diagram ensures a correct replacement.
What are the common symptoms that indicate the drain pump (137221600) is bad?
Common symptoms include: washer does not drain or drains very slowly, water left in the tub at end of cycle, pump makes a loud grinding or buzzing noise, pump hums but impeller does not spin, or visible leaks from the pump housing/hose connections. Error codes related to draining on machines with electronic control panels can also point to pump failure or blockage.
How can I safely test whether the pump is faulty?
Start with basic checks: unplug the washer and remove standing water, then inspect the pump inlet and hoses for clogs or foreign objects. With the washer still unplugged you can manually spin the pump impeller (if accessible) to see if it is indeed seized. For electrical testing, use a multimeter to check for continuity across the pump motor terminals-no continuity frequently enough means an open motor. If you are experienced and the service manual indicates the pump is powered by line voltage, you can briefly energize the pump with the correct voltage to see if it runs, but only after confirming wiring and with all safety precautions (power off before connecting/removing test leads). If unsure, have a qualified technician do the electrical testing-never work on live circuits without proper training.
How do I remove and replace the 137221600 drain pump?
Basic replacement steps (generalized; consult your model’s service manual): 1) Disconnect power and shut off water. 2) Drain any remaining water (use a bucket or towels) and access the pump by removing the appropriate access panel (front or rear). 3) Note or photograph wiring connections, then disconnect the electrical connector(s). 4) Loosen hose clamps and detach inlet/outlet hoses; be prepared for residual water. 5) Remove mounting screws or clips and take out the old pump.6) Install the new pump in the same orientation, tighten mounting hardware, reconnect hoses and clamps, reconnect the wiring exactly as before, replace panel, restore power, and run a drain/spin test. Replace any worn hose clamps and check for leaks during the test cycle.
My washer hums but doesn’t pump – is it the pump or a clog?
A humming sound with little or no draining can be either a seized motor or an obstructed impeller/hose. First check for debris in the pump inlet or the filter trap (if present) and clear any obstruction. If the impeller turns freely by hand and hoses are clear but the pump still only hums when energized,the motor windings or internal bearings are likely failing and the pump should be replaced.
Can foreign objects damage the 137221600 pump and how do I prevent that?
Yes. Coins, buttons, hairpins, small clothing items, and grit can jam or damage the pump impeller and wear the seals. Prevention steps: empty pockets before washing, use mesh laundry bags for small items, and periodically check and clean any lint or debris traps the washer may have. If a foreign object is suspected, remove the pump and inspect the impeller and housing; replace the pump if the impeller or motor is damaged.
What electrical specifications or tests should a technician use for the pump?
Electrical details (voltage, current, resistance) can vary by model and pump version-refer to the washer’s wiring diagram or the pump label. Typical drain pumps on residential washers are driven by AC line voltage through the machine’s control system. A technician should measure for continuity across the motor terminals (motor windings should not be open or shorted to the housing) and compare resistance to the manufacturer’s service specification. Also verify that control board outputs and wiring deliver the correct voltage to the pump during a drain cycle before replacing the control or pump. If you don’t have the service manual, consult a parts supplier or tech sheet for exact specs.
Where should I buy a replacement 137221600 and are there aftermarket alternatives?
You can buy the OEM 137221600 pump from Frigidaire authorized parts dealers, major appliance parts retailers, or reputable online marketplaces. Aftermarket pumps are frequently enough available and might potentially be less expensive, but ensure they are listed as compatible with your exact washer model and meet OEM fit and performance standards. Check seller return policies and warranty (OEM parts typically carry the manufacturer’s warranty). Always verify the part number and appearance against the original before installation.
