Washer displays E21; motor overload or stall detected during operation.

Safety first: Unplug the washer before inspecting the drum or motor.

• Reduce load: Remove some laundry and try a smaller load to see if the error clears.
• Check drum rotation: Spin the drum by hand. It should rotate smoothly and quietly. Grinding, scraping, or stiffness suggests bearing or foreign object issues.
• Inspect for obstructions: Look through the drum holes with a flashlight for trapped objects (e.g., bra wires, nails). Remove if visible.
• Check belt and motor: Remove the rear panel to inspect the drive belt for damage or misalignment. Ensure the motor turns freely by hand.
• If mechanical parts are fine: The motor windings or inverter module may be failing and should be tested and replaced by a technician.
