function and⢠role and Performance Requirements of âthe Dishwasher Drain Pump and Motor Assembly
The â 137108000 frigidaire Water Drain Pump and Motor Assembly isâ a compact electromechanical unit that evacuates âŁwash and rinse â¤water⢠from the â˘dishwasher sump⤠thru the drain hose and check valve. âThe assemblyâ combinesâ a small sealed motor, an impeller and âa housing with seals â˘and mounting points; the motor provides the torque and⣠head neededâ to â˘overcome the âdrain âtrap⣠and household plumbing backpressure while the impeller produces the required flow. Compatibilityâ depends on the â¤electrical⣠connector, âŁmounting footprint and gasket orientation, so replacement requires matchingâ those interfaces to the original⣠unit. Technically, the motor is designed for short-duty, wet-environment âŁoperation with âŁthermal protection â˘and a shaftâ seal to limit water ingress; common verification checks include listening for motor hum, measuring winding continuityand inspecting⤠the impeller and inlet for blockages⣠or mechanical damage.
- Common symptoms and âdiagnostics: âno drain with motor silent (electrical âfault or open circuit), humming without⣠flow (blocked impeller⤠or âseized shaft), â¤slow drain (partial blockage)and leaks (seal⢠or housing damage).
- Performance expectations: provide sufficient flowâ and⤠head to clear the sumpâ within the drain phase,â resist backflowand tolerate â˘detergents and suspended âfood particles for the rated service âlife.
- Installation considerations: âensure â˘correct electrical polarity/connections,secure mounting to prevent vibration,and⢠replace gaskets to maintain a âwatertight seal.
In âpractice, â˘technicians should treat âthe pump assembly as a replaceableâ hydraulic-motor subsystem: inspect â¤for foreign⢠objects âin the inlet screen, check the coupling between motor and⢠impeller for wearand âconfirm the control signals that energize the pump (timer/PCB or pressure/float switches). Field troubleshooting examples include isolating âthe pump from the control â˘boardâ to verifyâ direct â¤power operationand testing for proper backflow prevention âby observingâ drainage with â˘the unit energized and then de-energized. Selecting the correct 137108000 assembly or approved â¤equivalent â¤ensures âelectrical⢠rating,â mounting alignment and sealing details match the machine, avoiding â˘vibration, premature âfailureor leaksâ after service.

How the 137108000 Frigidaire Water Drain Pump and Motor Assembly Operates Inside âŁthe Appliance: Electrical,Mechanical and Fluid Dynamics
The 137108000 Frigidaire Water Drain Pump⣠and Motor Assembly is a compact electromechanical unit that⤠receives a timed âŁelectrical driveâ signal from the appliance controlâ board and âconverts that energy into centrifugal flow to evacuate washâ water. Inside the assembly a sealed electric motor turns a âmolded plastic impeller seated in a volute within the pump âhousing; as the impellerâ spins it acceleratesâ fluid radially,â creating a pressure differential that routes water âŁout through the drain hose âŁand check valve. The â¤motor type (singleâphase AC or lowâvoltage DC)â and⤠connector style vary by⢠model, so functional compatibilityâ depends âon âmatching the electrical supply, mounting flange, â¤and discharge orientation to the appliance chassis and âŁcontrol harness.
The pump’s âmechanical and fluid dynamics determine real-world behavior:⢠impeller geometry and volute shape set the flowâ vs. head⢠curve, while âclearancesâ and sealâ integrity govern leakage and bearing life. commonâ failure modes include impeller blockage (debris or small garments), shaft/bearing⢠wear â˘thatâ increases âtorque and draws excess current, âand seal⤠deterioration that permits water âintrusion â˘into⤠the motor cavity. Technicians commonly diagnose issues with âsimple checks – â¤listening for motor hum without rotation, checking current draw, inspecting the discharge forâ restrictions, âŁand performing a continuity test on the motor windings – and⣠should replace the unit with a âpart that matches electrical rating,â mounting tabsand hose fitting to restore expected flow andâ prevent âcavitation or overheating.
- Quick⤠diagnostics: humming/no spin (jammed impeller), no power⣠at connector (electrical/control fault), â¤leak at housing (seal failure), intermittent run (thermal protector cycling).

Common Failure â˘Modes âand âDiagnostic Symptoms for the Drain Pump⤠and âMotor Assembly
The âŁ137108000 Frigidaire Water Drain Pump âŁand motor Assembly evacuates defrost andâ condensate water from evaporator traysâ and drain pans, converting electrical input into impeller-driven flow. Common failure⢠modes include mechanical⢠obstruction of the impeller by debris or⤠ice, bearing â¤wear that produces high vibration âand⢠noise, impeller or housing damage that reduces flowand electrical faults such as open or shorted motor windings or intermittent connector corrosion.Compatibility â˘during replacement â˘is primarily⣠mechanical and⤠electrical: the replacement must match mounting points, connector âtype, rotational direction,â and the OEM-specifiedâ voltage and â˘current rating to ensure proper fit and correct⢠pump performance inâ the appliance plumbing and control system.
Diagnostic symptoms â˘map directly to âlikely failure mechanisms and canâ be verified with basic tests. Typical observable symptoms include no pumping despite applied â¤voltage (indicating a â¤seized impeller,broken coupling,or âopen winding),a humming motor with⣠no flow (mechanical âjam or⤠stuck impeller),continuous runningâ withoutâ removing water (check check valve orâ impeller damage),excessive noise â(bearing or rotor imbalance),and tripping breakers or high current âdraw (electrical â¤short or mechanical binding). Practical diagnostics include aâ visual inspection for debris â˘at the inlet, a manual âspinâ testâ of âthe â˘impeller â˘with power removed, voltage measurement⢠atâ the pump connector while the unitâ is calling for drain,â and an amp draw check under load to⤠compare against the â¤appliance service specification.
- No output but â˘motor hums – likely⢠mechanical⤠jam âor slipped/broken coupling.
- Intermittent operation âŁ- suspect corrodedâ connectors,thermal protectorâ cycling,or control board signal âŁissues.
- Loud grinding or vibration -â worn bearings⣠or rotor contact with housing.
- High currentâ or tripping – possibleâ winding short or mechanically bound impeller.
