This Part Fixes These Problems

Washer Won't Spin

The tub fills with water but does not spin. Worn or cracked rotor hub splines lose their grip on the tub shaft, preventing the motor from turning the drum during the spin cycle.

No Agitation

The washer runs but clothes are not being agitated or tumbled. A stripped hub center fails to transmit motor rotation to the wash basket in either direction.

LE Error Code

The LG control board displays an LE (motor error) fault. A damaged rotor hub can cause abnormal motor load readings, triggering this error and stopping the cycle.

Grinding or Scraping Noise

Unusual grinding or scraping sound from the bottom of the machine during operation. Damaged spline teeth or a cracked hub body cause the rotor to run off-center, contacting the stator.

Product Description

Why Choose Our MBF618448 Washer Rotor Hub?

🔧
Built to OEM SpecificationsManufactured to match the original LG MBF618448 spec — PBT-GF30 glass-fiber reinforced polymer body with a solid metal center shaft insert for maximum torque transfer and structural rigidity.
💪
Metal-Core Reinforced HubThe center of this rotor hub is constructed from metal, providing a stronger spline interface to the tub shaft — preventing the stripped-hub failure mode that is the #1 cause of LG washer no-spin complaints.
🧪
Chemical & Heat Resistant PBT-GF30 MaterialThe PBT-GF30 polymer housing withstands prolonged exposure to laundry detergents, bleach, and high-temperature wash cycles without warping or cracking — ensuring long-term dimensional stability.
🔄
Wide Cross-Reference CompatibilityDirectly replaces OEM part numbers 4413ER1001C, 4413EA1002B, 4413ER1002F, 4413ER1003B, 4413ER1003A, AHL72914401, AHL72914402, AGF78384401, and associated AP/PS/AH/EA cross-reference numbers — one hub covers a broad LG and Kenmore model range.
⚡
Restores Full Motor-to-Tub Power TransferThe rotor hub couples the direct-drive motor rotor to the wash tub shaft. When the spline teeth wear or crack, spin and agitation fail entirely. This replacement restores the electromagnetic coupling between rotor and stator so your tub rotates correctly in both wash and spin directions.
🛠️
Easy DIY Installation — No Special ToolsThree screws hold the rotor plate to the hub. Remove the rotor, swap the hub, reinstall — most technicians complete this repair in 20–30 minutes. No soldering, no calibration, no special equipment required.

💡 Pro Tip: How to Tell If Your Rotor Hub Is Bad

Your part is likely the culprit if you notice any of the following:

⚠️ Washer fills with water but tub does not spin or agitate at all

⚠️ Grinding or scraping noise coming from the bottom of the machine during the spin cycle

⚠️ LG error code LE (motor error) appears on the display panel

⚠️ Visible cracks, stripped spline teeth, or worn center cog when rotor is removed and inspected

🔍 Technician Tip: Remove the single large bolt at the center of the rotor and lift off the rotor plate. Inspect the black plastic hub — if the internal splines are rounded, chewed, or cracked, the hub is the culprit, not the stator or motor board. This part saves you from replacing the entire rotor assembly.

Questions & Answers

Will this MBF618448 rotor hub fit my LG WM2301HW washer?
Answered by Support Team  ·  Mar 15, 2024
Yes. The MBF618448 rotor hub is confirmed compatible with the LG WM2301HW. It directly replaces OEM part numbers 4413ER1001C, 4413EA1002B, 4413ER1002F, and 4413ER1003B used in that model. Before ordering, remove your existing rotor and confirm the hub mounts with 3 screws to the back of the rotor plate — that is the correct fitment indicator.
My LG washer shows an LE error code and won't spin. Could this rotor hub be the problem?
Answered by Support Team  ·  Nov 20, 2023
Possibly, yes. The LE error code on LG washers indicates a motor error, which can be triggered by a worn or cracked rotor hub causing abnormal motor load. Before replacing the hub, also check for clothing trapped between the drum and tub gasket, and inspect the rotor position sensor (6501KW2002A). However, if you remove the rotor and find the black plastic splines are rounded, stripped, or cracked, the hub is confirmed as the cause.
What is PBT-GF30 and why does it matter for this part?
Answered by Support Team  ·  Jan 8, 2025
PBT-GF30 stands for Polybutylene Terephthalate reinforced with 30% glass fiber. This is the same material specification used by LG in the original rotor hub. It offers high dimensional stability, resistance to laundry chemicals and bleach, and durability under the mechanical stress of repeated high-speed spin cycles. The metal center insert in this replacement hub provides additional shaft grip strength that the original OEM part sometimes lacks after years of use.
Do I need to replace the entire rotor assembly, or just this hub?
Answered by Support Team  ·  Jul 22, 2024
In most cases you only need to replace the rotor hub (MBF618448). The hub is the inner component that connects to the tub shaft via spline teeth. When those splines strip or crack, the hub fails — but the outer rotor plate with its magnets typically remains intact and reusable. Replacing just the hub saves significant cost compared to purchasing a full rotor assembly (AHL72914401 or AHL72914402), which can cost $40–$80 or more.
Is this compatible with Kenmore washers as well as LG?
Answered by Support Team  ·  Feb 10, 2026
Yes. Many Kenmore front-load washers sold under model numbers beginning with 796.XXXXX are built on the LG platform and use identical internal components. This MBF618448 rotor hub is compatible with Kenmore models including 796.40021900, 796.48842800, and 796.48852800, among others. Check your Kenmore model number — if it starts with 796.4, there is a high likelihood this hub is the correct fit.
