LG Washer Making Loud Noises
Expert diagnosis and repair for LG washer making loud noises issues.
Why Your LG Washer Is Making Loud Noises
LG washers are particularly susceptible to noise issues due to their direct drive inverter motor design and the unique spider arm assembly that connects the drum to the shaft. Unlike belt-driven systems, LG's direct drive technology means that when the drum bearings begin to fail, the noise is transmitted more directly through the motor assembly, creating distinctive grinding or roaring sounds. The company's use of plastic spider arms in many models, while effective for reducing vibration initially, can crack over time due to detergent buildup and thermal stress, leading to severe banging during the spin cycle.
The advanced ThinQ diagnostic system in newer LG models often displays error codes like UE (unbalanced load) or dE (door error) when noise issues arise, but these codes don't always pinpoint the root cause. LG's top-load and front-load designs both utilize unique shock absorber configurations that differ significantly from Samsung or Whirlpool units, requiring specific replacement procedures and genuine LG dampening components to restore proper operation.
Common Causes in LG Washers
Failed direct drive motor bearing assembly creating grinding sounds during agitation
Cracked plastic spider arm causing severe drum wobble and banging
Worn LG-specific shock absorber dampeners allowing excessive drum movement
Faulty rotor position sensor (RPS) causing erratic motor operation and noise
Deteriorated tub seal allowing water intrusion into bearing housing
Loose or damaged counterweight blocks specific to LG's balancing system
Failed inverter motor stator windings creating electrical humming or buzzing
Worn drum support roller assemblies in top-load models
Damaged suspension rods in front-load units allowing drum contact with cabinet
Commonly Affected LG Models
- WT7300CW, WT7305CW, WT7600HWA series - WM3900HWA, WM4000HWA, WM3700HWA series - WM3488HW, WM1388HW combo units - WT1901CK, WT1801CW top-load models - WM9000HVA, WM8000HVA large capacity front-loaders - WM3570HWA, WM3370HWA compact models
How We Fix This
Our TruePro technicians approach LG washer noise diagnosis by first running the built-in Smart Diagnosis through the ThinQ app or manual test mode to identify motor-related issues. We then perform a specific drum movement test unique to LG's direct drive system, checking for the characteristic "side-to-side" play that indicates spider arm failure versus the "front-to-back" movement suggesting bearing problems. For LG units, we always inspect the rotor position sensor connection, as loose wiring here can cause intermittent grinding noises that mimic bearing failure. When replacing components, we use LG's specified torque values for the drum assembly and ensure proper alignment of the direct drive motor to prevent premature wear.
Parts Commonly Needed
- Direct Drive Motor Assembly (part #4417EA1002G) - Drum Spider Arm Assembly (part #4413ER1003B) - Front Load Shock Absorber Set (part #4901ER2003A) - Tub Bearing and Seal Kit (part #4036ER2004A) - Rotor Position Sensor (part #6501KW2002A) - Counterweight Block (part #3841ER1006A) - Suspension Rod Assembly (part #4901ER2001C) - Drum Support Roller (part #4581EL2002A)
Troubleshooting Steps
Check for loose items in drum. 2. Verify machine is level. 3. Check shipping bolts removed. 4. Identify spin vs agitation noise.

- AE: The AE error code means the leak sensor in the base pan of your LG washer has detected water. A float switch or moisture sensor at the bottom of the unit triggered the alert. The washer stops the cycle and activates the drain pump to remove standing water. This error requires immediate attention — water is actively leaking inside the machine.
- CE: The CE error code means the main control board is detecting excessive or abnormal electrical current flowing to the drive motor. The board shuts down motor operation immediately to prevent damage. This is a protective response — something in the motor circuit is drawing more current than the board expects. The washer will not spin or agitate until the problem is resolved.
- CL: The CL display on your LG washer is not an error code. It means the child lock feature is activated. The washer ignores all button presses except the Power button. The door stays locked, and you cannot change cycles, start, or pause. This is a safety feature designed to prevent children from altering the cycle or opening the door during operation.
- dE: The dE error code signals that the door lock switch is not engaging. Your LG washer refuses to start any cycle until the door is securely latched and the lock mechanism confirms a closed position to the control board. The dE1 variant points to the lock mechanism itself, while dE2 relates to the door switch circuit.
- dE2: The dE2 error code means the door lock switch circuit is intermittent. The control board detects the door lock signal dropping in and out during a cycle. The washer interprets this as the door opening and closing repeatedly, which is a safety risk during spin. The cycle stops immediately. Unlike the general dE code, dE2 specifically points to the electrical side of the door lock — the switch or its wiring — rather than the physical latch.
- EE: The EE error code means the EEPROM chip on the main control board cannot be read or written to. EEPROM stores your washer's operating parameters, cycle data, and calibration values. The washer cannot function without this data. This is a board-level failure, and the machine will not run any cycle until the board is repaired or replaced.
