38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V is a combined drive motor and drain pump assembly designed for Speed Queen top-load washers; it is a two-speed, 120-volt electromechanical component that provides both rotational drive for the wash and spin cycles and the pumping action required to remove wash water. As a modular replacement kit, the part integrates a motor with the associated pump housing and mounting hardware so a single service operation restores both motion and drainage functions that are commonly located beneath the washer tub and cabinet.
Inside the appliance,this motor-and-pump kit serves as the primary actuator of mechanical and hydraulic subsystems: the motor delivers torque to the transmission,agitator or basket to perform agitation and spin operations at distinct speed settings,while the attached pump evacuates water from the tub to the drain line. The component interfaces electrically with the washer control (timer or electronic control board) and mains supply (120 V AC), and mechanically with the drivetrain/mounting bracket, pump hoses, and tub seal surfaces; its proper operation depends on correct mounting alignment, electrical connections, and unobstructed fluid pathways.
In this article readers will find a technical overview of how the 38034P motor-and-pump kit functions, guidance on determining compatibility with specific Speed Queen models (including electrical rating, connector types, and mounting points), common failure symptoms to watch for (for example: no agitation or spin, no draining, unusual noises, overheating, or intermittent operation), systematic troubleshooting steps to isolate motor versus pump faults, and practical replacement considerations such as verifying part numbers, handling wiring harnesses, securing pump seals, and safe service procedures. The goal is to provide technicians, engineers, and experienced appliance owners with the information needed to diagnose issues and make informed repair decisions without prescriptive or promotional claims.

Function and Role of the Washer Motor and Pump Assembly in Agitation, Spin, and Drain Cycles
The 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V combines a two‑speed induction motor and a centrifugal pump into one serviceable assembly that supplies the torque and fluid handling required for the washer’s agitation, spin, and drain cycles. In agitation the motor runs at a low speed and often reverses or pulses to generate torque against the load of water and clothes; in spin the motor switches to a higher speed to develop the rpm necessary to extract water from the load. The integrated pump is either driven directly from the motor shaft or via a dedicated coupling and operates during drain and spin-to-drain transitions, removing water from the tub and determining the drain rate. Matching the replacement kit to the appliance requires attention to the 120V rating, speed selection method, mounting flange, shaft orientation, and connector pinout so that the assembly interfaces correctly with the washer’s transmission or basket drive and its control system.
The motor/pump assembly responds to control signals from the timer or electronic controller and relies on mechanical and electrical elements-speed windings or a centrifugal switch, shaft couplings, impeller geometry, and thermal protection-to perform each cycle reliably.Technicians should recognize common functional symptoms: failure to agitate typically points to a motor winding,coupling,or low‑speed selection fault; failure to reach spin speed can indicate worn bearings,a bad high‑speed winding,or control wiring issues; and slow or no drain is often caused by pump blockage,impeller damage,or pump motor failure. Practical replacement considerations include verifying pump flow direction, ensuring proper sealing/gaskets at the mounting face, and confirming that the assembly’s control connections match the washer’s harness to avoid incorrect speed selection or continuous pump operation.
- Two operating speeds: low for agitation, high for spin.
- Integrated pump function: drains tub and affects drain time.
- Mechanical interfaces: shaft coupling, mounting flange, and impeller orientation.
- Common failure symptoms: no agitation, weak spin, noisy bearings, or clogged pump.

How the 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V Operates: Electrical, Mechanical and Hydraulic Interfaces
The 38034P Speed Queen 38034P Washer motor & Pump Kit 2-Speed 120V is an integrated motor and pump assembly designed for 120 VAC domestic washers and uses a two‑speed motor arrangement to provide low‑speed agitation and high‑speed spin. Electrically, the motor typically presents line and neutral power inputs plus one or two control leads or windings that the machine controller or timer switches between to select agitation versus spin. The pump is driven from the same assembly but may have a separate output or tap; its electrical feed is commonly tied into the same harness or supplied through a dedicated lead. Technicians should verify correct lead identification, proper grounding, and that the washer’s controller provides the correct switching signals and neutral reference to avoid incorrect rotation or improper speed selection during replacement or commissioning.
Mechanically, the assembly mounts to the washer frame with a defined bolt pattern and couples to the transmission or tub drive via a shaft coupling or bracket; the pump connects to the tub discharge path with a hose and a clamped fitting and relies on correct impeller orientation and clear inlet/outlet passages for reliable water removal. In practice this means inspecting the mounting alignment, shaft coupling, and pump inlet for obstructions when diagnosing symptoms: a humming motor with no spin often indicates a broken coupling or seized transmission, while motor running but no drain usually points to a blocked hose, damaged impeller, or electrical fault to the pump section. Confirming 120 V at the appropriate motor and pump terminals, checking continuity of control leads, and matching the replacement kit’s physical mounting and discharge orientation to the original are essential compatibility checks before installation.

Common Failure Symptoms and Diagnostic Indicators for the Motor & Pump Kit
The 38034P Speed Queen 38034P Washer Motor & Pump Kit 2-Speed 120V combines a two-speed drive motor with a matching drain pump to perform both agitation and high-speed spin cycles and to evacuate wash water. The two-speed 120V motor contains distinct electrical paths for low- and high-speed operation that the washer controller selects; the pump is mechanically separate but is mounted and matched for consistent flow and fit on Speed Queen tubs. In practice, the motor provides torque for agitation and centrifugal force for spin while the pump clears water; any replacement should match the electrical connections, mounting points, and rated voltage to avoid mismatched performance or control faults.
Common failure symptoms can be traced to electrical, mechanical, or hydraulic issues; technicians should use visual inspection, a multimeter, and simple mechanical checks to isolate the cause. Such as, a humming motor with no shaft rotation frequently enough indicates a start circuit or rotor seizure, while loss of drain with a normally spinning motor points to a blocked impeller or pump housing. Practical diagnostics include verifying 120 V at the motor/pump terminals during the expected cycle, checking continuity between motor windings and to ground, confirming that the pump impeller turns freely by hand, and inspecting connectors and harnesses for corrosion or overheating. Below are the common observable symptoms and quick diagnostic checks to prioritize during repair.
- No spin but tub fills/drains normally – check motor start/run selection voltage and winding continuity with a multimeter.
- No drain – inspect pump inlet and impeller for blockage and verify pump motor gets supply voltage during drain cycle.
- Humming or buzzing with no movement – test for locked rotor, failed start device, or seized bearings; measure current draw if possible.
- Intermittent operation – examine wiring harness, connector pins, and any thermal overloads or relay/switching devices in the control path.
- Loud grinding or rattling – remove and inspect pump impeller and motor bearings for debris or mechanical wear.
| Item | Description |
|---|---|
| No spin, motor hums | Probable start circuit failure or seized rotor; diagnostic: measure supply voltage at motor during spin command, check winding continuity, and inspect for mechanical binding. |
| no drain | Probable clogged impeller or failed pump motor; diagnostic: inspect pump housing, verify 120V is present at pump during drain, and check impeller free-play. |
| Intermittent cycles | Probable wiring/connectivity or thermal protection trip; diagnostic: wiggle-test harnesses, inspect connectors for corrosion, and check thermal overload or control relays. |
| excessive noise | Probable worn bearings or foreign object in pump; diagnostic: listen for bearing noise, remove pump to inspect impeller and shaft clearance. |
Compatibility, Replacement Considerations, Installation Steps and Troubleshooting Procedures for Speed Queen Models
The 38034P Speed Queen 38034P washer Motor & Pump Kit 2-speed 120V is a combined drive motor and drain pump replacement intended for specific Speed Queen top-load models that use a two-speed 120 V motor for agitate and spin functions. Confirm compatibility by matching the motor mounting flange, shaft diameter and length, pulley position, electrical connector pinout, and pump hose orientation to the original assembly; differences in transmission interface, clutch design, or tub mounting can prevent a direct swap. Such as,belt-driven machines that use the same pulley offset and a single multi-pin harness are often compatible,whereas machines with an integral transmission-mounted pump or option belt routing may require adapter brackets or harness modifications to achieve correct alignment and performance.
Follow a methodical replacement and diagnostic workflow: disconnect power, document connector locations and belt routing, support the tub and remove the old assembly, transfer any necessary pulleys or mounts, and torque fasteners to the manufacturer’s specification. After reassembly, perform functional checks for both speeds and for pump discharge; measure line voltage and motor winding continuity if the unit fails to start or runs weakly. common troubleshooting procedures include isolating the motor from the pump to verify free shaft rotation, checking for blocked pump impellers or collapsed hoses when drainage is slow, inspecting the centrifugal switch or start capacitor (if fitted) for intermittent faults, and confirming control board outputs during a diagnostic cycle. Practical observations – humming with no pump action, loss of one speed, or excessive vibration - point respectively to electrical start issues, worn brushes or windings, and misalignment or damaged mounts; resolving these typically involves targeted electrical tests and mechanical alignment checks.
- pre-install checklist: match mounting pattern, confirm connector pinout, verify pulley offset, and inspect pump hose fittings.
- Common symptoms: no spin (humming), no drain, single-speed only, excessive noise or leakage.
- Basic tests: supply voltage at motor, winding continuity (ohms), insulation resistance (megohm), and impeller free-spin.

Q&A
What washers does the 38034P Speed Queen Washer Motor & Pump Kit fit?
The 38034P kit is an OEM replacement used on Speed Queen washers that list part number 38034P in their parts list. Always confirm fitment by matching your washer’s model and serial number to the manufacturer parts diagram or the parts seller’s compatibility list. If your machine’s service manual or parts sheet specifies 38034P (or an exact equivalent OEM number), the kit will be correct; otherwise do not assume interchangeability.
What does “2-speed 120V” mean for this motor?
“2‑speed” means the motor has two operating speeds: a low speed used for agitation and a high speed used for spin. “120V” indicates it is designed to run on standard single‑phase 120 volt household power in North America. The motor has separate winding/lead connections for the two speeds and a common return; the pump may have its own feed or share circuits depending on the wiring harness.
Can I install this motor and pump kit myself?
Yes, a mechanically and electrically competent DIYer or technician can install it, but observe safety: disconnect power at the breaker, take photos or label wiring before disconnecting, relieve any stored energy, and follow the service manual. Typical steps: remove the washer cabinet, disconnect drive belt and motor/pump electrical connectors and hoses, unbolt the motor/pump assembly, transfer any required fittings, install the new assembly, reconnect hoses, wiring and belt, then test. If you are unsure about electrical wiring or moving heavy parts, have a qualified appliance technician install it.
how should the motor and pump be wired during installation?
Follow the wiring diagram for your specific washer model.Do not guess wire connections. The motor will have leads for low speed, high speed and common (and sometimes a separate lead for the pump). The pump might potentially be wired directly or through the motor harness. reconnect exactly as the original: match harness connectors or terminal positions and make sure the chassis ground is attached. If the original harness is damaged, replace it rather than improvising connections.If you can, label original wires before removal and verify with the service schematic.
The motor hums but the tub won’t spin after replacement – what should I check?
A humming motor frequently enough means the motor is getting power but not starting under load. Check: (1) the drive belt and pulley/clutch – a broken, slipped or seized clutch will stop spin; (2) the lid switch and safety interlocks; (3) rotor freedom – with power off, manually turn the motor/pulley to see if it’s seized; (4) start components - on some machines a start device or switch is used; (5) wiring and correct speed lead selection. If the motor hums and the rotor is locked, the motor may have internal mechanical failure or bad bearings and should be replaced.
The washer doesn’t drain after installing the pump – what are common causes?
If the pump runs but the tub doesn’t drain, inspect: clogged inlet/outlet hoses, a blocked pump impeller (lint/coins/labels), a clogged drain line or standpipe, or a stuck check valve in the drain system. verify hose clamps and orientation are correct and that the pump impeller is not damaged. If the pump does not run at all, check the pump electrical connection, fuse/house breaker, and that the washer is in a drain/spin cycle that energizes the pump.
My new motor/pump is noisy – what might be wrong?
Common causes of noise after installation include debris caught in the pump impeller, misaligned or loose belt and pulleys, loose mounting bolts or brackets, worn bearings in the motor or tub assembly, or a rubbing harness/pipe. Recheck all fasteners, ensure the belt has proper tension and alignment, clear the pump of foreign objects, and verify the motor mounts isolate vibration. If the noise is from inside the motor (bearing rumble), the motor may be defective and should be returned or replaced under warranty.
How can I safely test the motor and pump before reassembling the washer?
After reconnecting the motor and pump to the machine harness but before fully reassembling the cabinet, power the washer briefly on a test cycle to confirm function: run an agitation cycle to verify low speed operation and a spin/drain cycle to verify high speed and pump operation. Keep all covers off,keep hands and tools clear of moving parts,and do not run the machine unattended. You can also use a multimeter to check continuity of the motor windings and that the pump motor gets voltage during the drain cycle, but refer to the service manual for expected values and safe test procedures.
