Could a failing Washing Machine Shock Absorber (Friction Damper) cause the LG WASHER WM4000 to have symptom: Error Code Ue?

These 100N dampers provide the necessary friction to settle the outer tub during the transition to high-speed spin. When the internal grease or foam degrades, the tub bounces excessively, causing the sensor to detect a weight imbalance and trigger the UE code to prevent cabinet damage.

Could a failing Rotor Position Sensor (Hall Sensor) Assembly cause the LG WASHER WM4000 to have symptom: Error Code Ue?

This sensor monitors the exact speed and position of the drum via the motor's magnetic field. If the sensor is intermittently failing or dirty, it may send 'jittery' data to the control board, which falsely interprets the inconsistent RPM as a physical load imbalance.

Could a failing Washer Leveling Leg cause the LG WASHER WM4000 to have symptom: Error Code Ue?

Physical instability at the base of the machine amplifies natural vibrations during the spin cycle. A damaged or improperly adjusted leg prevents the machine from remaining 'true,' leading to resonant frequencies that mimic an unbalanced load.

What is the most likely root cause for a LG WASHER WM4000 with symptom: Error Code Ue?

These 100N dampers provide the necessary friction to settle the outer tub during the transition to high-speed spin. When the internal grease or foam degrades, the tub bounces excessively, causing the sensor to detect a weight imbalance and trigger the UE code to prevent cabinet damage.

LG WASHER WM4000 Error Code Ue

✅

System Nominal

The UE code is a safety feature intended to protect the direct-drive motor and drum bearings. It occurs normally when a single heavy item (like a rug or heavy towel) clumps to one side, or when the load is too small to distribute evenly around the drum circumference.

NO REPAIR ACTION REQUIRED. PHYSICS CHECK CONFIRMED.
