The 137108000 Frigidaire Water Drain Pump and Motor Assembly is a compact electromechanical module that combines a small electric motor with a centrifugal impeller and pump housing to remove standing water from an appliance. As a replaceable service part, it includes the rotating drive, impeller, sealing interfaces and the electrical connector or pigtail required to integrate with the appliance wiring harness.
Inside an appliance system this assembly performs the active drainage function, moving water from the wash or defrost area into the external drain line. It interfaces directly with the appliance control board or timer (for run commands), the drain hose and plumbing, and any water- or level-sensing devices that determine when a drain cycle is required. Mechanically it must resist debris and brief dry-running conditions while maintaining an effective seal and impeller clearance; electrically it must accept the control signal and provide the torque and flow needed to clear the system without overloading the motor or control circuitry.
This article will explain the assembly’s intended function and typical installation locations (appliances that require active water removal, such as dishwashers, washing machines and some refrigerator defrost systems), describe common compatibility considerations, list typical failure symptoms and diagnostic checks, and outline practical troubleshooting and replacement considerations for technicians and appliance owners. Topics covered include how the pump behaves in the system, common electrical and mechanical failure modes, test points and measurements to verify operation, and what to verify when selecting and installing a replacement unit.

Operational Function and System Role of the Drain Pump and motor Assembly
137108000 frigidaire Water Drain Pump and Motor Assembly provides the mechanical force to remove standing water from the appliance tub by converting electrical energy into rotational motion at the impeller. When the control board issues a drain command, the motor accelerates the impeller to create flow and pressure sufficient to overcome the appliance’s internal plumbing and household trap. the assembly’s sealed motor, impeller geometry, and discharge port determine flow rate, backflow resistance, and tolerance to particulates; proper sealing protects the motor from moisture and ensures reliable operation under repeated wet conditions.
The pump’s role in the system is governed by electrical and mechanical compatibility: correct connector pinout, mounting orientation, discharge hose alignment, and the motor’s rated input must match the appliance’s design to prevent leaks, incorrect flow direction, or electrical faults.Typical operational behavior includes intermittent on/off cycles during drain phases and short run times coordinated with sensors or timers. Common field symptoms that point to a failing pump are humming with no flow, intermittent pumping, visible leakage at seals, or the control board reporting a drain fault; diagnostics include verifying voltage at the pump during a drain cycle, inspecting the impeller and inlet screen for debris, and checking the discharge hose for obstructions or kinks. Replacing a defective unit with a compatible 137108000 part requires verifying physical fit and electrical compatibility rather than relying solely on part number similarity.
- No flow but motor hums - check impeller obstruction and verify voltage at the pump connector.
- Intermittent operation – inspect harness connections and control board drain relay signals.
- Leaks at housing seals – examine mounting gasket and replace pump assembly if seals are compromised.
- Reduced flow – clear inlet screen and discharge hose; confirm impeller condition.

How the 137108000 Frigidaire Water Drain Pump and Motor Assembly Integrates with Plumbing, Electrical, and Control Systems
The 137108000 Frigidaire Water drain Pump and Motor assembly serves as the hydraulic and electromechanical interface that evacuates collected wash and condensate water from the appliance to the household drain. Mechanically it mounts to the appliance chassis and links to the internal sump via a short inlet and a flexible outlet hose; correct hose diameter, outlet orientation, and presence of a check valve determine whether the pump can overcome trap head and standpipe height in a given installation. Flow capacity and generated head are primary behavioral characteristics – insufficient flow or head causes slow draining or retention of water, while incorrect hose routing or damaged gaskets produces leaks and airlocks. In practical repairs or replacements, verify that the pump outlet aligns with the existing drain hose, that any integrated filter or strainer is clear, and that the pump can physically access the drain path used by the original assembly (such as, discharge to a household P-trap or a washing machine standpipe).
Electrically and from a control perspective, the unit is driven by the appliance control system via a switched power circuit (typically a relay or semiconductor switch), and its motor is connected through the appliance wiring harness with a defined connector and grounding point.Verify voltage and connector pinout against the service manual before installation: mismatched voltage,reversed polarity where applicable,or incorrect grounding will prevent operation or create safety hazards. Control logic usually provides simple on/off commands and relies on the appliance’s sensors (float switch, pressure sensor, or current sensing) to terminate pump operation; some systems monitor pump current to detect clogs or stalled impeller conditions. For integration and troubleshooting, check continuity of the motor windings with a multimeter, inspect harness contacts for corrosion, confirm proper chassis mounting and vibration isolation, and run a diagnostic drain cycle to observe pump behavior under load.
- Plumbing: outlet hose size, trap/standpipe head, check valve and strainer alignment
- Electrical: verified line voltage, connector pinout, grounding and harness condition
- Control: on/off switching method (relay/triac), sensor inputs that stop the pump, diagnostic current monitoring
- Mechanical: mounting points, vibration isolation, and sealing to prevent leaks
- Troubleshooting checks: impeller blockage, coil continuity, and flow/head verification
| Item | Description |
|---|---|
| Hose connection | Matches appliance outlet; verify diameter and clamp force to prevent leaks or air ingress |
| Electrical interface | Appliance-specific harness connector and ground; confirm voltage and pin assignments |
| Control signal | Typically a switched supply from the control board (relay or solid-state); pump responds to on/off commands |
| Mounting | Chassis brackets or grommets provide mechanical support and vibration isolation; ensure seal at sump |
Common Failure Modes and Observable Symptoms of Pump and Motor Malfunction
The 137108000 Frigidaire Water Drain Pump and Motor Assembly evacuates wash water by combining a small AC motor with an impeller-driven pump housing; common mechanical failure modes include impeller blockage from debris, fractured or worn impeller vanes, shaft or bearing wear, and cracked pump housings or seals that allow leaks. Electrical failure modes include open or shorted motor windings, a tripped or failed thermal protector, degraded brushes or commutator wear (in brushed motors), and intermittent connector or harness faults. For example,a trapped coin can lock the impeller so the motor hums while drawing high current until the thermal cutoff trips,whereas bearing failure typically generates grinding noise and increased vibration before the assembly seizes.
Technicians should combine simple mechanical inspection with electrical checks to isolate root causes and confirm compatibility before replacing the unit: manually rotate the impeller to verify free movement and inspect the discharge port for obstructions; measure continuity across the motor terminals and check for proper mains voltage at the connector during a drain cycle; and visually compare mounting tabs, hose outlet orientation, and plug style to ensure a replacement matches the appliance. Replace the assembly if the housing is cracked, the impeller is damaged beyond repair, or electrical tests show an open circuit or short in the motor windings; if symptoms are intermittent, focus on connector integrity and insulation breakdown as likely culprits.
- No drain / standing water: impeller blockage, broken impeller, or open motor circuit.
- Humming without spin: jammed impeller, seized shaft, or failed start circuit/thermal protector.
- Grinding or rattling noise: bearing wear or foreign debris contacting the impeller.
- Intermittent operation: loose connector, damaged harness, or partial winding failure.
- Visible leak: cracked housing, failed seal, or improperly seated hose clamp.
| Item | Description |
|---|---|
| No drain | Inspect discharge hose and impeller chamber for blockage; verify motor continuity and apply voltage briefly with caution to check rotation. |
| Motor hums | Check for mechanical jam, test thermal protector for continuity, and measure winding resistance for opens/shorts. |
| Leaks | Examine housing for cracks, check seal surfaces and hose clamp seating; replace pump if housing is compromised. |
Field Diagnostics, Troubleshooting Procedures, and Replacement Considerations for Service Technicians
The 137108000 Frigidaire Water Drain Pump and Motor Assembly is an integrated impeller and motor unit that evacuates wash water through the drain hose by converting electrical input into rotational torque on a molded impeller. Mechanically, the assembly consists of a motor shaft, impeller, sealed housing, and mounting flanges that match specific Frigidaire chassis locations; electrically it interfaces to the appliance control via a keyed connector and is driven by the washer’s pump output circuit. Typical failure modes include impeller blockage, bearing wear, seal leaks, and open or shorted motor windings; these produce measurable symptoms (no flow, humming, unusual noise, or leakage) that should guide diagnosis rather than assumption that the entire appliance control is at fault.
Field diagnostics focus on isolating mechanical obstruction from electrical faults and confirming compatibility before replacement. start with a visual inspection for foreign objects and damaged seals, then verify presence of supply voltage at the pump connector during a drain cycle and measure coil resistance with a multimeter to detect open or shorted windings. If the motor receives correct voltage but does not spin and is not obstructed, bench testing the motor with an appropriate low-voltage or gated supply can confirm rotor condition; if bearings are noisy or the housing leaks, replace the assembly and ensure the replacement matches mounting tabs, connector pinout, and gasket orientation. Practical considerations: route the drain hose to avoid kinks, torque mounting hardware to prevent misalignment, and test a completed repair with a full drain cycle to confirm leak-free operation and correct flow rate.
- no drain but motor hums: check impeller for debris and measure motor coil continuity.
- intermittent operation: inspect wiring harness and connector for corrosion or loose pins.
- Loud grinding noise: suspect worn bearings or foreign object-replace assembly if impeller/motor housing is damaged.
- Leak at housing seam: replace pump and gasket and confirm proper seating of mounting flange.

Q&A
What appliances use the Frigidaire drain pump assembly part 137108000, and how do I confirm compatibility with my washer?
Part 137108000 is the drain pump and motor assembly used on a range of Frigidaire/Electrolux family washers. Compatibility varies by model and production date. The safest method is to check your washer’s model number (usually on a tag inside the door/frame or at the back) and cross‑reference that model with the part number on the manufacturer’s parts list or a reputable parts supplier. Do not rely on visual similarity alone – confirm the part number, electrical connector, mounting points and hose diameters match your machine.
What are the common signs that the drain pump (137108000) is failing or needs replacement?
common symptoms include: washer won’t drain or takes much longer to drain, error codes related to drainage, humming or grinding noises during the drain cycle, water leaking from the pump area, and visible debris or a seized impeller. If the pump runs but no water moves, it might potentially be clogged, the impeller may be broken, or the pump is not building suction and should be tested or replaced.
How can I test the pump motor safely to determine if it’s bad?
Always unplug the washer before doing any work. Visually inspect the impeller area for debris and check the impeller spins freely by hand. Use a multimeter to check the motor windings for continuity (open circuit indicates a failed motor). Because testing with live voltage is hazardous and can damage electronics, only a qualified technician should apply mains voltage directly to the pump for a bench test. Also check for continuity of the wiring harness and the drain circuit from the control board if you suspect an electrical control issue.
can I clear a clogged pump instead of replacing the 137108000 assembly?
Often yes – many drain problems are caused by lint, small clothing items, coins or hair jamming the impeller or pump inlet. After unplugging the washer, remove the access panel or filter and clear any debris, then test the impeller for free rotation. If the housing or impeller is damaged, leaking, or the motor windings are open, replacement of the entire pump assembly is recommended.
What is involved in replacing the 137108000 drain pump assembly? Do I need special tools?
Basic replacement steps: disconnect power,access the pump (rear or front lower access panel depending on model),disconnect the drain hoses and electrical connector,remove mounting fasteners,replace the assembly,reattach hoses and connectors,and run a test drain cycle.Tools typically needed are screwdrivers, pliers (for hose clamps), and possibly a nut driver or socket set. Take pictures during disassembly to help with reassembly. If you are not cozy working with appliance wiring or lifting the washer, hire a technician.
Why is the new pump making a loud noise or vibrating after installation?
Excessive noise can come from several sources: the pump may be hitting other components because of incorrect mounting, foreign objects trapped in the impeller, worn bearings (on a used or defective unit), mismatched/misaligned hoses, or an incompatible aftermarket part with a different motor speed.Verify the pump is mounted securely,the impeller is clear,and the part is the correct OEM or compatible replacement. If noise persists, replace the pump or consult a technician.
Can I replace the OEM 137108000 with an aftermarket pump, and will there be differences to watch for?
Aftermarket pumps can be a cost-effective option, but ensure the replacement matches the OEM in electrical specifications, connector type, mounting points, hose diameters and rotation direction. Lower‑quality pumps may have shorter lifespans,different noise characteristics,or fitment issues. When possible, choose a reputable supplier and verify a return policy or warranty.
how long does a drain pump like the 137108000 typically last, and is there a warranty?
Lifespan depends on use, water quality and maintenance; many drain pumps last 5-10 years under normal household use. heavy use, frequent foreign-object blockages, or power surges can shorten life. Warranty coverage varies by seller and whether the part is OEM or aftermarket – check the vendor’s warranty terms before purchase. If the washer is still under manufacturer warranty, contact the manufacturer or authorized service for covered repairs.
