Washer-dryer combo attempts to spin but stops and displays 3E. Drum may jerk or not move at all.

Safety first: Unplug the appliance before accessing the motor. Moving parts and high voltage are present.

Steps to troubleshoot:

• Reset power: Disconnect power for 5 minutes, then reconnect and try a spin-only cycle. Sometimes 3E is triggered by a transient glitch.
• Inspect motor connections: Remove the rear panel. Check the multi-pin connector at the motor and ensure it is fully seated. Look for damaged or corroded pins.
• Check rotor bolt: On direct-drive models, ensure the rotor bolt is tight and the rotor is not wobbling.
• Test spin: Reassemble and run a spin cycle with an empty drum to see if 3E reoccurs.

When to stop: If 3E persists, the hall sensor or motor assembly may need replacement. These parts are model-specific; professional diagnosis is recommended.
