How to Fix E28 Error (Step-by-Step)

Perform a safety reset by first unplugging the dryer from its power source.
Leave the unit unplugged for at least 10 minutes to allow the electronic controls to discharge and reset.
Clean the lint filter thoroughly, as this is a common cause of airflow-related errors.
Inspect the dryer’s vent hose for any kinks, and check the exterior vent cap to ensure it opens freely.
Plug the dryer back in and start a cycle and confirm the error stays cleared during a full test 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.
