How to Fix E20 Error (Step-by-Step)

Turn off the dryer and unplug it from the wall outlet for safety.
Wait for at least 10 minutes to allow all electronic components to fully discharge and reset.
While waiting, thoroughly clean the lint filter by removing all visible lint and washing it with warm, soapy water to remove any residue.
Check the dryer’s exhaust vent hose at the back and the vent opening outside your home for any blockages or restrictions. Clear any lint buildup you find.
After 10 minutes, plug the dryer back in and attempt to run a cycle.
Turn the appliance off, wait about 2 minutes, then turn it back on.
Check for simple blockages (lint screen, drain path, or filter) and clean anything you find.
