Dryer shows E20; on some models, this appears when starting a cycle with a very small load.

Safety first: Disconnect power before opening panels. Basic load checks can be done with the door open and power off.

• Adjust the load: Open the door and redistribute the laundry. Avoid drying a single heavy item (e.g., one towel); add a few more items to balance the drum.
• Check drum baffles: Inspect the plastic or metal baffles inside the drum. Tighten any loose screws and replace cracked baffles.
• Inspect suspension and rollers: If E20 occurs frequently with normal loads, check drum support rollers, rear bearing, and front felt for excessive wear that could cause vibration. Replace worn parts.
• Motor sensing: If mechanical components are sound, the motor current sensing circuit on the main control PCB may be overly sensitive or faulty, requiring board replacement.
