Display shows E20; the oven will not start, and the child lock symbol may be lit.

Safety first: No internal work is usually required for this error. Do not attempt to bypass safety features.

• Disable child lock: Refer to the Essentials user manual. Commonly, press and hold the key symbol or a combination such as Stop and Plus for 3–5 seconds until the lock icon disappears.
• Power reset: If the lock will not clear, turn off the oven at the breaker for 5–10 minutes, then restore power and try the unlock sequence again.
• Check for stuck key: If the lock key area is unresponsive, clean the touch panel and ensure nothing is pressing on it. If still stuck, the touch panel may need replacement.
• Service if persistent: If E20 remains after these steps, the control board or keypad may be faulty and should be checked by a technician.
