Washer shows E12, drum does not rotate correctly during wash or spin

Safety first: Unplug the washer before inspecting inside the drum or removing panels.

• Reduce load: Remove some items and run a spin-only cycle. Overloading is a common cause of E12.
• Check for drum obstruction: Rotate the drum by hand. Listen for scraping or grinding. Shine a flashlight through the drum holes to look for trapped objects (e.g., bra wires, coins).
• Inspect bearings: If the drum is very stiff or noisy when turned by hand, the rear tub bearings may be failing and causing motor overload.
• Advanced checks: Remove the rear panel and inspect the drive belt (if fitted) and motor. A burning smell or discoloration may indicate motor or inverter damage.
• Corrective action: Remove any foreign objects if accessible. For bearing or motor issues, replacement of the tub assembly or motor is usually required and is best done by a professional.
