How to Fix 3E Error

Unplug washer and remove rear panel.
Locate hall sensor connector on motor stator (3-wire white connector near motor windings).
Disconnect and inspect for corrosion or bent pins – clean with contact cleaner if needed.
Measure resistance between pins 1-2 (should read
5-3kΩ), pins 2-3 (same value).
Rotate drum manually 360° while monitoring resistance – should fluctuate smoothly without jumps.
Replace hall sensor DC31-00138A if open circuit or erratic readings detected.
If sensor tests good: check motor windings (U-V, V-W, W-U should read 5-15Ω balanced within 5%).
Replace main PCB DC92-01543A if motor and sensor both test good but error returns immediately on restart.
