Your LG washing machine handles hundreds of loads a year. It agitates, spins, drains, and rinses with a kind of mechanical precision most of us never think about — until something goes wrong. A strange grinding noise during the spin cycle, water that won’t drain, or a tub that wobbles more than it should can leave you staring at your washer like it’s a puzzle with missing pieces.
The truth is, an LG top-load washer is made up of dozens of individual components, and each one plays a specific role in getting your clothes clean. When you understand what those parts are and what they do, troubleshooting gets a whole lot easier. You stop guessing and start pinpointing.
That’s exactly what this guide is built for. Below, you’ll find a full breakdown of every major part shown in the LG washer parts diagram, from the lint filter sitting at the top all the way down to the base frame at the bottom. Each part is explained in plain language so you know what it does, why it matters, and what happens when it fails.
LG Washer Parts Diagram & Details
The diagram featured here is an exploded-view illustration of an LG top-loading washing machine. Every component is pulled apart and spread out vertically, giving you a clear look at how each piece sits in relation to the others. At the very top, you’ll see the lint filter and pulsator — the parts closest to your laundry during a wash cycle. Moving downward, the diagram reveals the inner and outer tubs, shock absorbers, the motor assembly (stator and rotor), the drain pump, and finally the base frame that holds everything together.
Each part is labeled with a reference code (K000, K021, K060, etc.), which corresponds to LG’s official parts catalog. These codes make it easy to order exact replacements if something wears out. The layout follows the actual stacking order of the washer’s internals, so you can visualize how each part fits during reassembly.
What follows is a detailed, part-by-part walkdown of this diagram. Whether you’re diagnosing a problem or simply curious about what’s inside your machine, the information below will give you everything you need.
1. Lint Filter (K000)
Sitting right at the top of the diagram is the lint filter — that circular mesh disc you might not pay much attention to during laundry day. Its job is straightforward but essential: it catches lint, loose threads, small fabric fibers, and other debris that gets released from your clothes during the wash cycle. Without it, all that gunk would either clog your drain system or redeposit onto your freshly washed garments.
Over time, the lint filter collects a surprising amount of material. If you’ve ever pulled it out and found it packed with fuzz, that’s a sign it’s doing its job well. Cleaning it regularly — ideally every few weeks — keeps water flowing freely through the drum and prevents the kind of buildup that can lead to drainage issues or musty odors inside the tub.
2. Pulsator (K021)
Right below the lint filter sits the pulsator, sometimes called the wash plate. It’s that wing-shaped or propeller-like disc that sits at the bottom of the inner tub, and it’s the part responsible for creating the water currents that move your clothes around during a wash. Rather than using a traditional center-post agitator, LG’s pulsator design generates a swirling motion that’s gentler on fabrics while still delivering a thorough clean.
The pulsator rotates in alternating directions, pushing water upward and outward through the laundry load. This action helps detergent penetrate deep into the fabric and loosens dirt without the kind of harsh twisting that wears out clothes faster.
When a pulsator wears down or cracks, you’ll often notice your clothes coming out less clean than usual, or you might hear a scraping sound during the wash. Replacing it is typically a simple job — it’s held in place by a single bolt underneath — making it one of the more DIY-friendly repairs on this list.
3. Pulsator Cap (K012)
This small but important piece sits directly on top of the pulsator’s center mounting point. The pulsator cap covers and protects the bolt that secures the pulsator to the drive shaft below. It keeps water and debris from getting into that connection, which could cause corrosion or loosen the fit over time.
It’s a part most people overlook entirely. But if it goes missing or cracks, moisture can work its way down to the shaft bolt, and that can lead to rust or a pulsator that starts wobbling during operation. Replacements are inexpensive and snap right into place.
4. Inner Tub Mounting Bolt (K030)
This is the primary bolt that holds the pulsator firmly to the inner tub’s drive shaft. It threads down through the center of the pulsator and anchors it to the rotating mechanism below. The fit has to be tight — any play here means the pulsator won’t spin properly, and you’ll end up with uneven wash performance.
If you’re removing the pulsator for cleaning or replacement, this bolt is the first thing you’ll need to loosen. A socket wrench usually does the trick. Just be aware that after many cycles, this bolt can seize up due to corrosion from moisture exposure, so a penetrating lubricant might be necessary before you try to unscrew it.
5. Suspension Rod Mounting Bolts (K040)
Farther to the right in the diagram, you’ll notice a set of small bolts that secure the suspension rods to the outer tub. These bolts take on a lot of stress during the spin cycle, especially when the washer is dealing with an unbalanced load. They anchor the top ends of the suspension system, ensuring the tub stays connected to the shock-absorbing rods.
Even though they’re small, these bolts are load-bearing. If one shears off or loosens, you’ll hear banging or thumping during high-speed spins, and the tub may shift visibly. Checking their tightness during any tub-related repair is a smart habit to build.
6. Suspension Bushings (K050)
Paired with the mounting bolts, the suspension bushings are rubber or composite fittings that sit where the suspension rods meet the outer tub. They provide a cushioned connection point, allowing the rods to absorb movement and vibration without transferring all of that energy directly to the tub housing.
These bushings degrade gradually. Exposure to heat, moisture, and constant mechanical stress wears them down, and once they crack or flatten, the ride gets rough. Your washer might start vibrating excessively or “walking” across the floor during the spin cycle. Replacing the bushings is usually part of a suspension overhaul and can make a noticeable difference in how quiet your machine runs.
7. Outer Tub (K100)
The large container on the left side of the diagram is the outer tub — the main structural vessel that holds all the water during a wash cycle. It’s the bigger, non-perforated tub that the inner drum sits inside. While the inner drum spins, the outer tub stays stationary, acting as the watertight shell that prevents your laundry room from flooding.
Made from heavy-duty plastic or composite material in most LG models, the outer tub also serves as the mounting point for the suspension system, the motor, and the drain pump. It’s the backbone of the entire washer assembly. Cracks or leaks in the outer tub are serious — they usually mean water on the floor and a repair that’s more involved than most.
Because of its central role, every other part in this diagram either mounts to, sits inside, or connects directly to the outer tub. Keeping it in good condition means everything else works the way it’s supposed to.
8. Shock Absorbers (K060)
The long, rod-like components extending from the sides of the outer tub are the shock absorbers, also known as suspension rods or dampers. Their entire purpose is to keep the tub stable during the spin cycle, especially when the drum is spinning at high RPMs with an unbalanced load of wet laundry inside.
Each shock absorber connects the outer tub to the base frame and works like a piston — compressing and extending to absorb movement. When they’re working properly, your washer barely moves during a spin. When they’re worn out, the tub bounces around inside the cabinet, and you’ll hear loud banging, thumping, or vibrations that you can feel through the floor.
Most LG washers use four shock absorbers, and it’s generally recommended to replace all of them at once. Even if only one is visibly worn, the others are likely close behind, and replacing the full set ensures balanced dampening across the tub.
9. Wire Harness / Power Connector (K104)
Over on the right side of the diagram, you’ll spot a cord or cable component — this is the wire harness or power connector. It carries electrical current from the washer’s control board to the motor and other internal components. Think of it as the machine’s nervous system, delivering power and signals where they need to go.
A damaged or corroded wire harness can cause all sorts of unpredictable behavior: error codes on the display, a motor that won’t start, or sensors that give false readings. During any internal repair, it’s worth inspecting the wire harness for frayed wires, burnt connectors, or loose plug connections.
10. Tub Gasket / Seal (K250)
Positioned between the outer tub and the components below it, the tub gasket is a rubber seal that prevents water from leaking past the tub’s base. It creates a watertight barrier around the shaft opening where the drive mechanism passes through the bottom of the outer tub.
This is one of the most common failure points in any washing machine. Over years of use, the seal dries out, cracks, or warps from exposure to detergent chemicals and heat. A failing tub gasket shows up as water dripping from the bottom of the washer, which is easy to misdiagnose as a pump leak or a hose issue. If you see water pooling underneath your machine, the tub seal should be one of the first things you check.
11. Thermistor / Water Temperature Sensor (K064)
This small sensor, tucked near the lower portion of the tub area, monitors the temperature of the water inside the drum. It sends real-time readings back to the control board, which uses that data to regulate heating elements and ensure the water reaches the temperature you selected for your wash cycle.
When the thermistor fails, your washer might default to cold water regardless of your settings, or it could trigger an error code related to temperature. Testing one with a multimeter is straightforward — you’re looking for a specific resistance value at room temperature — and replacing it usually involves disconnecting a single plug and swapping in the new sensor.
12. Stator Assembly (K170)
Below the tub, the circular disc with evenly spaced holes is the stator. It’s one half of the washer’s direct-drive motor system. The stator is a stationary electromagnetic coil that creates a magnetic field when electricity passes through it. That field interacts with the rotor (directly below it) to create the spinning motion that turns the drum.
LG’s direct-drive motor design mounts the stator directly to the back of the outer tub, eliminating the need for belts or pulleys. Fewer moving parts means fewer things that can break. The stator itself is a durable component, but if its windings short out or burn, the motor won’t produce enough torque, and you’ll notice weak spinning or complete failure to agitate.
13. Rotor Assembly (K140)
Paired with the stator, the rotor is the part that actually spins. It’s a ring of permanent magnets that sits just outside the stator. When the stator generates its electromagnetic field, the rotor responds by rotating — and since it’s connected directly to the inner drum’s shaft, the drum spins with it.
The beauty of LG’s direct-drive system is the simplicity of this interaction. No belts to slip, no pulleys to crack. The rotor and stator talk to each other through magnetic force alone. That said, the rotor can develop issues if its magnets crack or if the mounting bolts that hold it to the shaft loosen. A rattling noise during spin, especially one that sounds metallic, can sometimes point back to a rotor problem.
14. Water Inlet Valve Assembly (K200)
On the lower left of the diagram, you’ll see a bracket-mounted assembly — this is the water inlet valve. It controls the flow of hot and cold water into the washer. When you start a cycle, the control board sends an electrical signal to open the valve, allowing water to flow in at the right temperature and volume.
Most LG washers use a dual or triple solenoid valve, with separate paths for hot, cold, and sometimes a dedicated bleach or softener line. If one solenoid fails, you might get only cold water when you’ve selected warm, or no water at all. Mineral buildup from hard water can also clog the valve’s inlet screens over time, restricting flow. Cleaning those tiny screens with a brush and vinegar can sometimes fix a slow-filling washer without needing a full valve replacement.
15. Drain Hose Connector (K310)
This smaller component near the drain area connects the drain hose to the pump or tub outlet. It’s a coupling piece that ensures a secure, leak-free path for wastewater to travel from the tub to the drain pump and then out of the machine.
Clamps or clips usually hold this connector in place, and they can loosen over time from vibration. A slow drip near the bottom of your washer that only appears during the drain cycle might be traced back to a loose or cracked hose connector rather than the pump itself.
16. Drain Pump Motor (K201)
Every drop of dirty water that leaves your washer passes through the drain pump. This motor-driven component forces water out of the tub and through the drain hose during the drain and spin portions of each cycle. It has to generate enough pressure to push water up and out, often against gravity if the drain standpipe is higher than the pump.
A clogged drain pump is one of the most common washer repairs. Coins, hair ties, small socks, and other items that slip past the drum can get lodged in the pump impeller, blocking it from spinning. You’ll hear a humming sound — the motor trying and failing to turn — followed by a drain error code. Clearing the blockage often fixes the problem instantly.
In cases where the motor itself has burned out, the pump won’t hum at all, and water will simply sit in the tub. Replacement drain pumps for LG washers are widely available and typically mount with just a few screws and a wiring clip.
17. Clutch / Coupling Assembly (K210)
This gear-like component sits between the motor and the inner drum’s drive shaft. The clutch assembly controls the transfer of rotational force from the motor to the drum, engaging and disengaging as needed during different parts of the wash cycle. During agitation, the clutch allows the pulsator to oscillate back and forth. During the spin cycle, it locks in to deliver full-speed rotation.
Clutch wear tends to show up as a washer that agitates fine but won’t spin at full speed, or one that makes a grinding noise during the transition from wash to spin. Because this part handles the mechanical handoff between two very different types of motion, it’s subject to significant wear, especially in households that run heavy loads frequently.
18. Base Frame Assembly (K350)
Near the bottom of the diagram, the base frame is the structural foundation of the entire washer. It’s a rigid platform — usually stamped steel or reinforced plastic — that sits on the floor and supports the outer tub, the motor, the pump, and the suspension system.
The base frame absorbs the forces generated during the spin cycle and keeps the machine stable. Leveling legs or feet typically bolt into the frame’s corners, allowing you to adjust the washer’s height and balance on uneven floors. If the frame itself bends or cracks — rare, but possible after years of heavy use — the entire machine can become unstable, and no amount of leveling or suspension work will fix the vibration.
19. Base Plate / Drain Filter Cover (K251)
At the very bottom of the diagram sits the base plate, which doubles as a protective cover for the drain filter area. It shields the underside of the washer from dust, debris, and pests, while also providing access to the drain filter or pump cleanout port on models that include one.
On many LG top-loaders, this plate is removable, giving you a way to access the pump and lower plumbing connections without tipping the machine over. If your washer has a drain filter accessible from outside, this cover is what you’ll remove to get to it. Keeping this area clean and free of lint buildup helps maintain proper airflow around the motor and prevents overheating during long or back-to-back cycles.
