Washer-dryer shows E20, often related to motor overheating or overcurrent

Safety first: Unplug the appliance and allow it to cool for at least 30 minutes if it has overheated.

• Reduce load: Remove some items and run a smaller load to see if the error recurs.
• Check drum rotation: With power off, spin the drum by hand. Listen for scraping or grinding that could indicate a trapped object or bearing issue.
• Inspect motor area: Remove the rear panel and check for obstructions around the motor and belt. Ensure the belt is correctly tensioned and not binding.
• Advanced diagnostics: If E20 persists with normal loads, the motor or inverter may be failing. Testing current draw and inverter output should be performed by a qualified technician.
