137108000 Frigidaire Water Drain Pump and Motor Assembly is a combined electromechanical component used to evacuate wastewater from an appliance chassis. The assembly typically comprises a small electric motor that drives a molded impeller within a plastic pump housing, together forming a self-contained drain pump module that mounts to the washer or dishwasher tub and connects to the drain hose and wiring harness.
Inside the appliance, the drain pump is responsible for removing water during drain and spin cycles and for maintaining expected fluid flow through the appliance’s plumbing. It is indeed commanded by the machine’s control board or timer and works in series with the tub, drain hose and any inlet/outlet filters, traps or check valves; the assembly also interfaces electrically with the appliance wiring and, indirectly, with sensors such as level/pressure switches and door/lid interlocks that govern cycle progression. Proper operation of the pump is essential to complete cycles, prevent standing water, and avoid overflow or damage to other components.
This article will explain how the 137108000 assembly functions, how to verify model compatibility and part substitution, typical failure symptoms (for exmaple no-drain, slow-drain, excessive noise or leakage), and practical troubleshooting steps technicians and owners can apply. It will cover basic electrical and mechanical diagnostic checks, common causes of failure (obstructions, impeller damage, motor windings or bearing issues, and seal leaks), and replacement considerations such as correct orientation, gasket/seal condition, harness connections, and post-installation testing. Safety precautions, recommended tools for diagnosis, and tips for confirming fitment across appliance models will also be addressed.

Function and Role of the Drain Pump and Motor in Frigidaire Appliances
The 137108000 Frigidaire Water Drain Pump and Motor Assembly converts electrical control signals into rotational torque to drive an impeller that forces wastewater out of the appliance sump and through the drain hose. The motor is typically an AC or DC shaded-pole/brush motor depending on model, directly coupled to a molded plastic impeller; the control board energizes the motor when the machine’s drain cycle is initiated or a water-level/flood sensor requests evacuation. Proper operation depends on free impeller rotation, an unobstructed outlet path (trap and hose), correct electrical supply and secure connector pins; mechanical fit and inlet/outlet dimensions determine compatibility with specific Frigidaire chassis and pump cavities.
Technically, failures usually fall into electrical faults (open winding, poor connector contacts), mechanical blockage (debris jamming the impeller), or hydraulic issues (clogged hoses, incorrect hose routing or check-valve failure). Typical diagnostic steps include confirming control-board drive voltage at the pump connector, measuring motor winding resistance for continuity, and verifying impulse-free rotation of the impeller by hand after power is removed.Replacement requires matching the assembly’s mounting footprint, connector type and rated voltage; installing the wrong orientation or connector can prevent sealing and cause leaks or insufficient flow. For safety, isolate mains power before testing or removal and follow model-specific service instructions when confirming compatibility or performing a replacement.
- Common symptoms: pump hums but does not drain, no motor response, persistent error codes for drainage, visible leaks from pump housing, or intermittent operation.
- Basic checks: inspect and clear inlet filter, verify drain hose routing and height, measure connector voltage during a drain cycle, and check motor winding continuity.

How the 137108000 Frigidaire Water Drain Pump and Motor Assembly works Inside the Appliance
The 137108000 Frigidaire Water Drain Pump and Motor Assembly is a compact electromechanical unit that evacuates wash and rinse water from the appliance sump during drain cycles. the part consists of an electric motor directly coupled to a molded impeller inside a volute-shaped housing; when the control board applies voltage the motor produces torque that accelerates the impeller, converting rotational energy into fluid flow and pressure to push water through the outlet and drain hose. The housing commonly includes mounting bosses, an integrated debris screen or trap, and a keyed electrical connector so the assembly can be replaced as a single unit; technicians should confirm compatibility by matching the part number, connector pinout, and mounting orientation to the appliance service parts list before installation.
during normal operation the control board energizes the pump for the duration of the drain command, and the pump will run until commanded off or until the system detects low water level.Typical failure modes are mechanical obstruction of the impeller, bearing wear that produces noise or reduced flow, and electrical faults such as open windings or a tripped thermal protector. Practical diagnostic steps include measuring supply voltage at the pump connector during a drain cycle, checking motor winding continuity with a multimeter, removing and inspecting the impeller chamber for debris, and confirming the drain hose and check valve are free of kinks or blockages. When replacing the assembly, ensure hose clamps and seals are correctly seated and that the pump orientation matches the original to prevent air locks and improper drainage.
- symptoms and rapid checks: humming with no discharge (impeller jam), no power at connector (control/wiring issue), intermittent operation (thermal cutout or loose connection), noisy operation (bearing or foreign object).

Common Failure Symptoms and Diagnostic Indicators for the Drain Pump and motor
The 137108000 Frigidaire Water Drain Pump and Motor Assembly is a compact electromechanical unit that removes liquid from the tub by converting electrical energy into torque at a molded-plastic impeller. In normal operation the motor receives a timed drain command from the control board, spins the impeller smoothly, and maintains sufficient flow to clear the drain hose and trap; compatibility depends on matching the part number, connector pinout, and mounting flange to the appliance model. Typical failure behavior includes failure to start, intermittent operation, unusual noise, or leakage; these symptoms often arise from electrical faults (open windings, connector corrosion), mechanical obstruction (foreign objects or collapsed hoses), or bearing/seal degradation that increases drag on the motor shaft. For example, a machine that completes wash agitation but leaves water in the tub commonly indicates either a clogged discharge path or a pump/motor that is not receiving drive voltage or has an open circuit in the windings.
- No spin or hummmng: check for voltage at the pump during a drain cycle and test continuity across the motor leads; an open circuit indicates a failed motor.
- Intermittent draining: inspect hose and impeller for debris, and verify connector integrity and control board relay output.
- Loud grinding or rattling: remove the pump and inspect the impeller/bearing for foreign objects or wear.
- Leakage or oil at the base: seal failure typically requires replacement of the assembly rather than repair.
| Item | Description |
|---|---|
| Visual check | Inspect hoses, inlet screens, and impeller for obstructions or damage. |
| Electrical test | Measure continuity across motor terminals and verify control-board output voltage during drain. |
Diagnostic indicators that point to motor failure versus system-level issues include a consistent absence of drive voltage (control or wiring fault) versus a present voltage with no mechanical response (motor or mechanical blockage). Measured continuity through the motor windings should show low but finite resistance; a true open circuit or very high resistance indicates a burned winding or disconnected lead. Under powered operation, a meaningful increase in motor current, audible grinding, or a burnt-odor are reliable indicators of mechanical seizure or internal electrical failure and justify replacement of the pump assembly. When replacing the unit, verify the 137108000 Frigidaire Water Drain Pump and Motor Assembly matches the appliance model, connector type, and hose orientation to ensure proper fit and restore reliable drainage.
Compatibility Matrix: Supported Frigidaire Models and Electrical/Mechanical Interface Specifications
The 137108000 Frigidaire Water drain Pump and motor Assembly is characterized in the compatibility matrix by its electrical ratings, connector type, and mechanical mounting features so technicians can determine fit and function across Frigidaire model families. The pump’s role is to evacuate wash or condensate water through an impeller-driven housing; compatibility depends on matching the pump’s electrical supply and control signals, the harness/terminal style, the physical mounting footprint, and the hose/inlet diameter to the appliance. service parts lists that include this assembly commonly pair the part number with specific model numbers and notes about adapters, grommets, or harness conversions required for a direct replacement.
A practical compatibility check includes verifying the motor nameplate or wiring diagram for rated voltage and current, confirming that the harness pinout matches the appliance control board, and measuring mounting hole spacing and outlet barb size for hose fitment. Typical mechanical and electrical interface considerations that affect interchangeability include the pump’s mounting flange geometry, the inlet/outlet orientation and diameter, the connector style (sealed plug, blade terminals, or wire leads), and the motor’s thermal protection or direction-of-rotation requirements; replace a pump only when these parameters match or when a documented adapter is available. Examples: if a washer uses a two-pin quick-disconnect and the replacement has pigtail leads, a compatible harness adapter or re-termination is necessary; if mounting holes differ by more than a few millimeters, a bracket or OEM adapter is required.
- Verify rated voltage and current on the motor label against the appliance wiring diagram.
- Match harness connector type and pinout before installation.
- Confirm inlet/outlet diameters and mounting-hole spacing for mechanical fit.
- Check pump flow direction and duty cycle against the appliance’s expected operation.
| Item | Description |
|---|---|
| Electrical Interface | Rated voltage/frequency and current are on the motor label; common household installations use 120 V/60 Hz control outputs-confirm pinout and any required neutral/ground connections. |
| Mechanical Interface | Mounting flange pattern, inlet/outlet barb diameter, and housing orientation determine physical compatibility; measure against the old assembly or service diagram. |
| Compatibility Notes | Some models require grommet or bracket adapters, harness conversions, or minor clearance adjustments; consult the model-specific service bulletin or parts cross-reference before replacing. |
Replacement Considerations, Safety Precautions, and step-by-Step Installation Notes
The 137108000 Frigidaire Water Drain Pump and Motor Assembly is an integrated pump/motor unit that evacuates wash water from the tub by driving a small centrifugal impeller. technically,the assembly combines an electric motor,impeller,and sealed housing so that mechanical wear,hydraulic restrictions,or electrical faults can produce distinct symptoms: a dead pump (open or shorted winding),a humming motor with no rotation (mechanical seizure or blocked impeller),or external leakage at seals or hose connections. When evaluating compatibility, match the electrical rating and connector style stamped on the label, confirm mounting-hole alignment and gasket diameter, and verify that the replacement unit’s impeller orientation and drain outlet align with the appliance’s hose routing to avoid cavitation or air locks during operation.
- Disconnect power and unplug the appliance before beginning any work.
- Isolate and capture residual water by running a manual drain or placing towels and a shallow pan beneath the pump area.
- Document wire positions or photograph the harness before disconnecting to ensure correct reconnection.
- Inspect the impeller for debris and verify motor winding continuity with a multimeter before full reassembly.
- After installation,run a short drain cycle and inspect for leaks and unusual noise; re-torque fasteners if vibration loosens them.
During replacement, use a methodical, torque-light approach: remove the access panel, relieve any trapped pressure, detach inlet/outlet hoses at the clamps, and unbolt the pump while supporting it to avoid stressing the wiring harness. Before powering up, confirm the motor winding resistance is within manufacturer tolerances (compare to the old part or service data), seat any rubber grommets or seals evenly to prevent leaks, and secure the harness with the original clips to prevent chafing. Practical examples include clearing small coin debris from the impeller recess before installation and routing the drain hose without high loops that can trap water; these details reduce the chance of repeat failure and ensure reliable operation on the first test cycle.
| Item | Description |
|---|---|
| Operating voltage | Verify on the unit label (typically 120 V AC for North American models). |
| Connector type | Match the OEM harness pin count and locking tab to avoid splicing or adapter use. |
| Symptoms | No pump/noise/leak: motor open/short, seized impeller, or seal/gasket failure. |
Troubleshooting Procedures and Diagnostic Tests for Pump and Motor Fault Isolation
The 137108000 Frigidaire Water Drain Pump and Motor Assembly is a self-contained pump that converts electrical input into rotational torque at the impeller to evacuate standing water.In service the assembly behaves as a small centrifugal pump: flow falls with increased discharge restriction and the motor current rises under mechanical load. replacement compatibility depends on physical mounting, connector pinout, and rated voltage/current, so match the housing footprint and electrical connector when swapping parts. For field technicians, inspection of the pump housing, impeller clearance, and mounting seal often explains intermittent drainage faults more reliably than bench testing alone.
- Symptom checks: no drain, weak flow, humming without rotation, rattling noise, or visible leaks.
- Quick functional tests: manually spin the impeller to check for seizure; verify supply voltage at the connector; check for continuity of the motor windings with an ohmmeter.
- Mechanical checks: remove debris from the inlet/outlet and inspect for broken or clogged impeller vanes and bearing wear.
| Item | Description |
|---|---|
| Function | Electrically driven centrifugal pump to evacuate water from the appliance sump. |
| Electrical interface | Two- or three-pin connector; verify pinout and rated supply on the pump label before applying power. |
| Common failure modes | Impeller obstruction, bearing wear, open/shorted windings, connector corrosion. |
Begin diagnostics with a safety-first approach: Disconnect power before testing and then perform a visual inspection. With power removed,check for mechanical binding by rotating the impeller; if it binds,disassemble the sump or hose path and remove trapped debris. With the harness accessible, restore power briefly to measure voltage at the pump connector while commanding a drain cycle; if correct voltage is present but the motor does not run, measure winding continuity and insulation to chassis for opens or shorts. Use a clamp ammeter during a run attempt to compare running current against the expected draw (noted on the pump housing or service sheet); elevated current with low rotation indicates mechanical overload or bearing failure, while an open winding indicates electrical failure and necessitates replacement of the assembly.
Q&A
What is the 137108000 Frigidaire Water Drain Pump and Motor Assembly used for?
The 137108000 is a replacement drain pump and motor assembly used to remove water from Frigidaire appliances that use a separate electric drain pump (common in many dishwashers and some washer models). It contains the electric motor, impeller housing and the discharge port/check valve. If your appliance model lists this part number, it replaces a failed or damaged factory drain pump.
How do I know if the drain pump is the cause when my appliance won’t drain?
Common symptoms of a failing drain pump include no draining at all, very slow draining, loud grinding or rumbling noises during the drain cycle, or water leaking from the pump housing. To isolate the pump, confirm the appliance completes fill and wash cycles, check the drain hose and sink disposal for clogs, and then inspect the pump for debris or foreign objects. If the pump motor does not run when it should, or if it runs but does not move water, the pump assembly is likely defective.
Can I clean or repair the 137108000 pump, or must I replace the entire assembly?
Most modern drain pump assemblies are not serviceable beyond removing debris from the impeller area. If the impeller is jammed by small objects (glass, food, string), you may be able to clear the blockage and restore function. However, if the motor windings are burned, bearings are noisy/worn, or the housing is cracked, replacement of the entire assembly is the recommended and typical repair.
How do I test the pump motor to see if it is electrically good?
First disconnect power to the appliance.Remove the electrical connector from the pump and use a multimeter to check for continuity across the motor terminals-continuity indicates the winding is intact; an open circuit indicates a failed motor. You can also check for short-to-ground by measuring resistance from each motor terminal to the pump housing (should be very high/OL). Exact resistance values vary by model, so continuity testing is the safe basic check. Only apply mains power to the pump directly for a functional test if you are qualified and take all safety precautions.
How do I replace the 137108000 drain pump and motor assembly?
Turn off and disconnect power and water to the appliance. Access the pump by removing the lower access panel (dishwasher) or front/bottom panels (washer). Disconnect the drain hose and any mounting clips or screws holding the pump, and unplug the electrical connector(s). Remove the old assembly and install the new one in the same orientation, reconnect hoses with proper clamps, plug in electrical connectors, and secure mounting fasteners. Restore power and run a test cycle to check for leaks and correct operation. If unsure,consult the appliance service manual or a qualified technician.
Do I need to match the part number exactly,or will similar drain pumps fit?
Always confirm compatibility with your appliance model number and the appliance parts diagram. some pumps are interchangeable between models, but differences in mounting tabs, hose sizes, electrical connectors, or discharge orientation can prevent a proper fit. Using the exact part number (137108000) or an OEM-approved replacement is the safest choice for correct fit and function.
is it safe to run the appliance if the pump is noisy or leaking until I get a replacement?
no. Running an appliance with a noisy or leaking pump risks further damage and water leaks that can cause electrical hazards, cabinet/wall damage, or mold. if the pump is badly noisy, intermittently running, or leaking, shut off power and water and arrange for repair or replacement promptly.
How much does a replacement 137108000 pump typically cost and is there a warranty?
Retail prices vary depending on supplier and whether the part is OEM or aftermarket; typical ranges are roughly $50 to $150. installation costs vary if you hire a technician. Many manufacturers and parts suppliers offer limited warranties (often 90 days to one year) on replacement parts-check the seller and Frigidaire warranty terms for the exact coverage before purchase.
