137108000 Frigidaire Water Drain Pump and Motor Assembly is an electromechanical drain pump that combines a compact electric motor with an impeller housing to remove wastewater from an appliance’s tub or sump. As a replaceable service part,it is indeed designed to sit inline with the appliance’s drain plumbing and to be driven by the appliance control electronics when a drain cycle is commanded.
Inside an appliance, the drain pump interfaces directly with the wash or rinse tub, the drain hose, and the appliance control board or timer; it also works in conjunction with water-level sensors, door or lid interlocks, and pressure or float switches to ensure proper sequencing of fill and drain operations.Mechanically, the assembly must maintain a seal against the sump to prevent leaks and provide sufficient flow rate and head to overcome vertical lift and hose resistance; electrically, it must accept the appliance’s supply voltage and control signals while offering thermal protection appropriate to the motor design.
This article will provide a technical overview of the 137108000 assembly, covering how the pump functions, typical applications and compatibility considerations, common failure modes and diagnostic symptoms (such as no drain, reduced flow, unusual noise, or leakage), step-by-step troubleshooting checks to isolate electrical versus hydraulic faults, and practical replacement considerations including mounting, sealing, connector matching, and basic test procedures to verify a correct installation. the goal is to give technicians, engineers, and informed appliance owners a clear, practical reference for assessing and replacing this component in service situations.

Function and Role of the Drain Pump and Motor Assembly in Frigidaire Laundry Appliances
The 137108000 Frigidaire Water Drain Pump and Motor Assembly is a combined electric motor and centrifugal impeller mounted in a molded housing that evacuates wash water from the tub during drain and spin cycles. The motor receives a command from the appliance control board and drives the impeller to create the flow needed to push water through the drain hose and out of the machine; the assembly also integrates mounting points and electrical terminals matched to specific Frigidaire washer models for direct replacement. In practice, this assembly is selected for compatibility with the washer’s control signals, harness connector, and physical mounting pattern rather than as a generic pump, so technicians should verify chassis mounting, connector pinout, and any rubber gaskets or brackets when ordering or installing the part.
Common operational behaviors and failure modes are mechanical obstruction of the impeller, electrical faults in the motor windings, or leakage through a cracked housing or failed seal. Troubleshooting typically includes verifying that the control board sends line voltage to the pump during the drain phase, checking continuity across the motor terminals with a multimeter, and inspecting the impeller and inlet for debris that reduces flow.When replacing the unit, ensure proper seating of the gasket and secure electrical connections; after installation, confirm that the pump runs only during drain/spin operations and that there is no unusual vibration or fluid leakage under load.
- Symptoms: no drain, motor hums, intermittent operation, reduced flow, or visible leak at pump housing.
- Inspection steps: check drain hose,clear impeller debris,verify control board output voltage,measure motor continuity.
- Installation notes: match mounting pattern, connector pins, and replace any worn gaskets or retaining clips.

How the 137108000 Frigidaire Water Drain Pump and Motor Assembly Operates: Mechanical, Electrical, and Control Interfaces
The 137108000 Frigidaire Water Drain Pump and Motor Assembly combines a compact motor and molded pump housing to move wash water from the tub to the drain hose.Water is drawn into the volute by a small impeller fixed to the motor shaft; the impeller and housing geometry create the pressure necessary to overcome the static head of the drain line. The motor is a low-inertia, single-phase design intended for intermittent duty and is normally powered directly from the appliance control board. Mechanical failure modes include clogged impeller passages, worn shaft bearings, or ruptured seals that allow leakage into the motor cavity; electrical failure modes present as an open winding, shorted turns, or a thermal protector that has tripped under excess load. in normal operation the pump runs only long enough to evacuate the tub, so thermal protection and intermittent duty ratings are part of the component specification.
Control and electrical interfaces are simple but must match the appliance harness and control strategy: the board typically supplies mains voltage to the pump through a relay or triac and uses the pump state indirectly via water-level sensing rather than direct feedback from the motor. When replacing the assembly, verify connector pinout, mounting orientation, and outlet alignment to ensure proper hose routing and clearance.For practical diagnostics and service, always disconnect power before accessing the pump; common checks include verifying continuity across the motor terminals, applying a controlled supply to confirm impeller rotation, and inspecting the filter and inlet for debris. Typical symptoms, basic troubleshooting steps, and a concise reference for interface details are listed below.
- Symptoms: no spin with humming (mechanical jam or failed bearings), no continuity (open winding), intermittent operation (thermal protector or loose connection), leak at housing (seal failure).
- Electrical checks: measure line-to-line continuity, verify control board drive at the connector when drain cycle is commanded, and test operation with a lab power source if safe to do so.
- Mechanical checks: remove debris from inlet, inspect impeller for damage, confirm mounting gaskets and hose clamps are secure and aligned.

Common Failure Symptoms, Root Causes, and Diagnostic Procedures for Drain Pump and Motor Malfunctions
The 137108000 Frigidaire Water Drain Pump and Motor Assembly provides the mechanical action that evacuates water from the appliance’s tub or sump; it is a replaceable electromechanical module that must match the appliance harness and mounting for proper fit and operation. Typical malfunction behavior includes the pump running without moving water, intermittent operation, loud bearing or grinding noise, or complete electrical failure.Compatibility should be verified against the appliance model number and wiring harness-physically similar pumps can have different voltage or connector pinouts,so confirming plug type and rated voltage prevents misdiagnosis and damage. For example, a pump that hums but does not pump is frequently enough obstructed by debris trapped in the impeller, while a pump that never energizes might potentially be fine mechanically but not receiving control voltage from the main board or timer.
- Noisy operation (bearing wear or foreign object contact)
- No water flow despite motor hum (impeller jam or leak in discharge hose)
- No electrical continuity or open winding (electrical failure)
- Pump runs continuously or not at all (control signal or board issue)
Diagnostic procedures prioritize isolating electrical faults from mechanical ones: first confirm the appliance issues the drain command and measure the voltage at the pump connector during the active drain period; a proper command should show the rated supply (often mains-derived) at the connector. Test the motor windings with a multimeter for continuity and insulation to ground-an open winding or a short to ground indicates replacement. Bench-testing the pump by applying the rated voltage with the assembly removed can verify rotation and noise under load; inspect the impeller and volute for foreign objects, collapsed hoses, or pinched discharge lines that can mimic electrical failure.If the pump motor shows correct winding resistance and receives correct control voltage but still fails under bench test, bearing failure or internal hydraulic damage is highly likely; in that case replace the 137108000 Frigidaire Water Drain pump and Motor Assembly and verify post-replacement that the control board supplies the expected signals and that hoses are clear.
| Item | Description |
|---|---|
| Continuity | Motor windings should show low ohms; open = replace |
| Control Voltage | Measured at connector during drain cycle; matches appliance spec |
| Impeller Freedom | Impeller should spin freely; obstruction or seized bearings require replacement |
Compatibility, Replacement considerations, and Step-by-Step Installation Guidelines for the 137108000 Frigidaire water Drain Pump and Motor Assembly
The 137108000 Frigidaire Water Drain Pump and motor Assembly is the combined impeller housing and electric motor that evacuates wash water from the tub and route it out through the drain hose. In operation the impeller creates a low-pressure flow path; the motor provides rotational torque and is usually thermally protected.Failure modes are typically mechanical (clogged or broken impeller, foreign object jamming, worn bearings) or electrical (open windings, intermittent connector/circuit faults). Confirm compatibility by matching the part number, mounting flange orientation, electrical connector type, and hose diameter to the appliance before ordering; two pumps with similar external shapes can have different electrical pinouts or mounting offsets, which will affect fit and function in tight chassis environments.
- Safety first: disconnect power and water supply before inspecting or replacing the pump.
- Verify part number and compare harness connector, mounting holes, and hose barb diameter against the existing unit.
- Check continuity of the motor windings and rotate the impeller by hand to confirm free movement.
- Inspect for debris in the housing, damaged seals, or cracked impeller vanes that justify replacement rather than service.
| Item | Description |
|---|---|
| Electrical | Verify voltage and connector type on the appliance label; many North American units use 120 V AC but confirm before installation. |
| Mounting | Match flange orientation, screw pattern, and hose barb location to ensure proper fit and clearances. |
| Common symptoms | Slow or no draining, unusual noise during drain, water remaining after spin, or visible leaks at the pump housing. |
typical installation follows a controlled sequence: remove the access panel, lower or drain residual water into a bucket, detach the inlet/outlet hoses and electrical harness, and unfasten the pump mounting screws. Transfer any gaskets or mounting brackets to the replacement unit if they are serviceable, position the pump so the hose alignment and wiring harness reach naturally without strain, and secure the pump to the chassis with the original fasteners tightened to a snug torque to avoid distortion. After reconnecting hoses and the harness, perform a short diagnostic or drain cycle while observing for leaks, abnormal vibration, or motor noise; if leakage or binding occurs, recheck clamps, sealing surfaces, and impeller clearance before returning the appliance to service.
Q&A
What are the common symptoms that the 137108000 Frigidaire water drain pump and motor assembly is failing?
Typical signs include: the appliance won’t drain or is very slow to drain; standing water in the tub or dishwasher; a loud humming or grinding noise during the drain cycle; water leaking from the pump area; or the appliance showing a drain-related error code. Humming with no water movement frequently enough indicates a jammed impeller or a seized motor.
How can I confirm the 137108000 drain pump is the problem?
First unplug the appliance and turn off water if applicable. Visually inspect the pump inlet/outlet and hoses for clogs (coins, debris, lint). Try to manually rotate the impeller (if accessible) to see if it’s seized. Use a multimeter on the motor terminals (set to continuity/ohms) – an open circuit (infinite resistance) typically means a failed winding; continuity to chassis/ground indicates an internal short. If the motor gets power during the drain cycle but doesn’t run, the pump assembly is likely faulty.
Does the 137108000 assembly include the motor, impeller, and seals or do I need extra parts?
The 137108000 is sold as a pump and motor assembly, which generally includes the motor, pump housing and impeller. Mounting brackets, rubber grommets, hose clamps or additional seals may or may not be included depending on the supplier. Always check the product listing and your appliance parts diagram to confirm what’s in the box and whether you’ll need replacement clamps or gaskets.
Is the pump easy to replace and what tools are required?
Replacement difficulty is moderate. Basic hand tools (screwdrivers, pliers, nut drivers) are usually sufficient. You’ll typically remove an access panel, disconnect hoses and wiring, unbolt the old pump and install the new unit. Allow 30-60 minutes for someone agreeable with appliance repair. Always unplug the appliance and, where applicable, shut off water supply before starting. If you’re not comfortable with electrical hookups or accessing internal components,hire a qualified technician.
Will installing a new 137108000 pump fix all drain problems?
If the pump is defective (electrically failed, seized, or damaged), replacing it usually resolves drain failures. However, drainage problems can also be caused by blocked drain hoses, kinked plumbing, a faulty control board, or clogged filters/traps. Diagnose for obstructions and verify control/valve function before replacing the pump when possible.
How do I test the electrical side of the pump safely?
Always disconnect power first. With the pump accessible,remove the connector and use a multimeter to check resistance across the motor terminals – an open circuit suggests a failed motor. Also check for continuity between the motor housing and ground; any continuity can indicate a short to ground. If you must test while powered, only do so if you are trained and take proper precautions (risk of shock). For most owners, it’s safer to have a technician perform live tests.
How long should a 137108000 drain pump last and what shortens it’s life?
typical service life varies widely by usage and conditions but is often several years (commonly 5-10 years). Factors that shorten life include frequent debris entering the pump (coins,hair,grease),hard water mineral buildup,electrical surges,and repeated short drain cycles. Regular cleaning of filters, traps and inlet screens helps prolong pump life.
Where should I buy a replacement 137108000 and does it come with a warranty?
Buy from authorized Frigidaire parts dealers, reputable appliance parts retailers, or the manufacturer’s parts website to ensure you get a genuine replacement. Some trusted aftermarket suppliers also sell compatible units – verify fit and compatibility with your exact model number before purchase. Warranty coverage varies by seller and part (commonly limited manufacturer or seller warranties); check the warranty terms and return policy before buying.
