Function and Operational Role of the Frigidaire Drain Pump and Motor Assembly in Water Evacuation
The 137108000 Frigidaire Water Drain Pump and Motor Assembly is the electromechanical module that evacuates wastewater from the appliance by converting electrical energy into hydraulic flow. The assembly combines a small electric motor and a molded impeller/volute so that when the motor is energized during drain cycles the impeller generates pressure and directs fluid through the drain outlet and hose. Physical design features that affect behavior and compatibility include the impeller geometry, inlet/outlet port size and orientation, mounting flange pattern, and the type of electrical connector; these factors determine flow capacity, noise characteristics, and fitment in different Frigidaire chassis variants. In operation the unit runs only during controlled drain intervals or pump-out commands and can be observed pulsing or running continuously depending on the appliance’s programmed drain strategy and sensor feedback (for example, water-level sensors or timers).
From a service perspective the assembly is a field-replaceable component but must match the original part’s mechanical and electrical interfaces to ensure safe operation. Technicians should verify that the pump housing and outlet align with the appliance drain path, that the connector pinout and wire colors correspond to the wiring diagram, and that gaskets or seals are properly seated to avoid leaks. Typical failure modes are impeller blockage, foreign-object jamming, worn motor bearings, and electrical faults such as open windings or intermittent brushes; simple bench checks include visual inspection for debris, manual impeller rotation, and continuity testing of the motor circuit. Practical examples: a dishwasher that hums but does not pump often has a seized impeller or debris in the volute, while intermittent draining can indicate failing brushes or a loose connector.
- Common symptoms: humming without flow, intermittent operation, audible grinding, premature shutoff due to low flow.
- Pre-replacement checks: verify physical fit, inspect hoses for kinks, confirm connector pinout, clear debris from inlet screen.
- Service tips: replace gaskets, test motor continuity, confirm drain hose and air gap are free of obstructions.

Internal Mechanics and Electrical Operation of the 137108000 Frigidaire Water Drain Pump and Motor Assembly
137108000 Frigidaire Water Drain Pump and Motor Assembly combines a compact electric motor and molded impeller inside a sealed plastic volute to move wastewater out of the appliance.The motor is designed for mains-powered, intermittent duty and converts electrical energy in its windings into rotational torque that turns the impeller; mechanical features include a keyed shaft, sealed bearings, and a shaft seal or molded housing lip to keep water away from electrical components. In operation the control board supplies switched line voltage to the pump terminals during the drain cycle, and the fixed-rotation impeller and volute geometry translate torque into a directed flow that clears the drain hose and filter path.
for service and compatibility, technicians should verify that the replacement pump matches the original mounting points, electrical connector type, and discharge orientation to maintain proper flow characteristics and avoid motor overload. Common diagnostics include checking for mains voltage at the pump connector during a drain command, verifying continuity in the motor windings, and inspecting the impeller and inlet for debris or entanglement that causes humming without rotation. Practical failure modes and maintenance considerations are summarized below to aid troubleshooting and selection of a compatible replacement.
- Features: integrated motor-impeller unit, sealed volute, swift-connect electrical terminals.
- Common symptoms: humming with no flow (blocked impeller or seized bearings), no power at connector (control or wiring fault), intermittent operation (thermal or partial winding failure).
- Service tips: clear debris from inlet, measure voltage during drain cycle, compare connector and mounting to OEM unit before replacement.
| Item | Description |
|---|---|
| Motor function | Converts supplied AC mains to rotational torque for the impeller; designed for short duty cycles. |
| Impeller/volute | Molded impeller matched to housing to provide required flow and head for the appliance drain path. |
| Electrical interface | Simple two- or three-terminal connection controlled by the appliance PCB or relay; verify plug type for compatibility. |
| Failure indicators | Humming, no rotation, leaks at housing, or open/shorted windings on continuity check. |
Common Failure Modes and Diagnostic Symptoms for the drain Pump and Motor
The 137108000 Frigidaire Water Drain pump and Motor Assembly combines a compact motor and molded pump housing to eject wash water through the drain line; it converts electrical input into sustained impeller rotation and must match mounting, connector pinout, and rotation direction for direct replacement. Typical failure modes include mechanical blockage of the impeller (foreign objects, lint or hair wrapping), bearing or shaft wear that increases radial play, and electrical faults such as open windings or shorted coils. In many frigidaire machines the assembly is service-replaceable as a unit, so technicians should verify connector type, housing orientation, and clearance before assuming compatibility with other pump assemblies that may look similar but use different electrical ratings or mounting lugs.
- No spin, no hum: open winding or disconnected power; verify continuity and harness voltage.
- Humming without rotation: seized bearings or jammed impeller causing high current draw and thermal stress on the motor.
- Slow or intermittent spin: partial obstruction, worn brushes (if applicable), or slipping due to degraded bearings.
- Excessive noise or grinding: foreign debris contacting the impeller or failed bearings/shaft misalignment.
- Leakage at housing: cracked pump housing or failed seal allowing water ingress to motor area and electrical contacts.
| item | Description |
|---|---|
| High inrush/high running current | Indicative of mechanical seizure, bearing failure, or blocked impeller; measure current against spec. |
Diagnostic workflow should start with non-invasive checks: confirm supply voltage at the pump connector, inspect the impeller chamber for obstructions, and attempt to rotate the impeller by hand to assess bearing looseness or binding. Use a multimeter to measure coil resistance and an insulation check to ground; an open coil or low insulation resistance indicates an electrical failure and usually requires replacement of the assembly. For example, a washer that hums and trips the board will commonly show normal line voltage at the connector but elevated current and a motor that cannot be freely turned, pointing to mechanical seizure rather than control-board failure. When replacing, match the 137108000 Frigidaire Water Drain Pump and Motor Assembly connector pinout, mounting orientation, and rated voltage to avoid mismatched installation and repeat failures.
Replacement Considerations, Model Compatibility Verification, and Installation Procedure
The 137108000 Frigidaire Water Drain Pump and Motor Assembly performs the mechanical work of evacuating wash water from the tub and forcing it through the drain hose; its motor drives an impeller that must remain free of obstructions and sealed from the wet chamber. Typical functional failures are mechanical (jammed or eroded impeller, worn bearings, cracked plastic housing), hydraulic (incorrect hose ID, improper orientation, or backflow), and electrical (open windings or bad connectors). Verify compatibility by comparing the pump’s electrical rating, connector pinout, mounting footprint, and hose interface to the appliance service data and the removed unit – differences in flange orientation, rotation, or connector arrangement can lead to incorrect installation or immediate failure when powered.
- Compare part numbers and appliance model cross-reference before purchase.
- Confirm electrical specification and connector pinout against service manual.
- Measure hose inner diameter and check clamp type for a leak-free fit.
- Check mounting bolt pattern and clearance to avoid stress on the pump housing.
- Inspect for required gaskets, brackets, or spacer pieces to transfer from old pump.
| Item | Description |
|---|---|
| Electrical rating | Match pump voltage and frequency to the appliance wiring and circuit protection. |
| Connector | Verify pin count, keyed orientation, and secure seating of the harness plug. |
| Mounting footprint | bolt pattern and flange orientation must align to avoid stress and leaks. |
| Hose interface | Inner diameter and clamp type must provide a sealed path with correct slope. |
Installation requires isolation of power, removal of access panels, and draining residual water into a pan before disconnecting hoses and the electrical harness to prevent short circuits or contamination; retain any gaskets or brackets from the old unit for fit verification. Fit the replacement so the pump body and impeller orientation match the original, secure mounting fasteners evenly to avoid distorting the plastic housing, reconnect the harness and hoses with new clamps if necessary, then run a controlled drain or drain-only cycle while observing for smooth motor sound, adequate flow, correct direction of discharge, and absence of leaks; if the motor hums without moving water, check for impeller obstruction and verify motor continuity with a multimeter rather than applying power repeatedly.
Q&A
What is the 137108000 Frigidaire Water Drain Pump and Motor Assembly and what does it do?
The 137108000 assembly is a replacement drain pump and motor used in certain Frigidaire appliances. Its job is to move wastewater out of the appliance (washing machine, dishwasher, or similar) through the drain hose and into the household drain system. The motor spins an impeller inside the housing; the impeller produces the flow needed to evacuate water.
What are common symptoms that this drain pump is failing?
Common signs include: appliance does not drain or drains very slowly; persistent standing water after a cycle; unusual noises during drain (loud grinding, clanking, or a high-pitched hum); error codes related to drain or pump; visible leaks from the pump housing or hose connections; or the motor hums but the impeller does not spin. These symptoms can also be caused by blockages or control/wiring problems, so confirm diagnosis before replacing the pump.
How can I test the pump to confirm it needs replacement?
Basic tests: (1) Safety first – unplug the appliance and turn off water. Inspect the pump for visible debris and try to turn the impeller by hand (it should turn freely). (2) Electrical test – with the appliance unplugged, check motor winding continuity with a multimeter; you should see continuity (a low to moderate resistance), not an open circuit; also check for short to ground. (3) Operational voltage test – with extreme caution (appliance powered and in drain cycle), check that the pump is receiving the expected supply voltage (typically 120 VAC in North America) at the pump connector; if voltage is present but the motor does not run, the pump is bad. If no voltage is present,the issue may be a control board,timer,or switch. If you are not agreeable working with live voltage, have a trained technician perform this test.
How do I no if this part is compatible with my Frigidaire appliance?
Confirm compatibility by comparing the appliance model number (usually on a label inside the door or on the cabinet) with the part cross-reference list from Frigidaire or an authorized parts dealer. Also compare the part number stamped on yoru existing pump with 137108000 and visually verify mounting points, electrical connector type, and hose sizes. If in doubt, provide your appliance model number to the parts supplier to ensure you recieve the correct replacement.
What are the basic steps to replace the drain pump (safety and high level)?
High-level replacement steps: 1) Disconnect power (unplug or switch off circuit breaker) and turn off water if applicable. 2) access the pump by removing the lower front or rear access panel per your model’s service manual. 3) Place towels or a shallow pan under the pump to catch water. 4) Disconnect electrical connector(s) and remove hose clamps to free the inlet/outlet hoses. 5) Remove mounting screws or clips and take out the old pump. 6) Install the new pump, transfer any gaskets or brackets, reconnect hoses and clamps, and attach wiring. 7) Reassemble panels, restore power, and run a test cycle to check for leaks and proper drainage. If you encounter sealed or glued connections, or if you are uncomfortable with disassembly, contact a technician.
What tools do I need and how long does replacement usually take?
Typical tools: Phillips and flathead screwdrivers, pliers (hose clamp pliers recommended), a nut driver or small socket set for mounting screws, towels or a drain pan, and a multimeter if you plan to test electrical function. For someone comfortable with basic appliance repair, replacement often takes 20-60 minutes; for less accessible installations or if additional diagnostics are required, it can take longer.
Why is the new pump noisy or leaking after I installed it?
Possible causes: trapped debris or foreign object in the pump impeller, loose or misaligned hose clamps, damaged or missing gasket/seal, incorrect installation orientation, or a defective replacement unit. Also check that the pump mounting is secure and not rubbing against the cabinet. If noise is a grinding/clanking sound, inspect the impeller for damage. If a leak appears at a hose connection, re-seat the hose and tighten the clamp or replace the clamp if it’s damaged.
how much does this pump typically cost and is there a warranty?
Retail prices vary by supplier but the drain pump assembly typically falls in a moderate price range for OEM replacement parts. Expect a wide ballpark depending on supplier and region; check multiple authorized parts dealers. Many manufacturers and parts suppliers offer limited warranties (commonly 90 days to one year) on replacement parts - verify the specific warranty with the seller or Frigidaire. If the appliance is still under the manufacturer’s warranty,contact Frigidaire support before replacing the part yourself.
