How to Fix Bosch Dryer Error KEY SYMBOL

Error Code: KEY SYMBOL Difficulty: Easy

Problem: The childproof lock is activated, locking the control panel.

How to Fix KEY SYMBOL Error (Step-by-Step)

1. Recognize that the key symbol means the childproof lock is active, which prevents settings from being changed accidentally.
2. To deactivate the lock, locate the button or buttons used to control it. This is often the ‘Start’ button or a button with a small key icon next to it.
3. Press and hold this specific button for approximately 3 to 5 seconds.
4. Watch the display screen. The key symbol should disappear, and you may hear a beep, indicating the control panel is now unlocked.
5. You can now select a cycle and change any settings as needed.
6. To reactivate the child lock after starting a cycle, simply press and hold the same button again for 3-5 seconds until the key symbol reappears.
7. Turn the appliance off, wait about 2 minutes, then turn it back on.

Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
