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

  1. Identify the key symbol on the display, which indicates the childproof lock is active and the controls are locked.
  2. Locate the button or buttons used to activate and deactivate the child lock. This is often indicated by a small key icon next to a button.
  3. Press and hold the designated button (often the ‘Finished in’ or ‘Time Dry’ button) for approximately 3-5 seconds.
  4. Watch the display for the key symbol to disappear, which confirms the control panel is now unlocked.
  5. You can now operate the dryer normally by selecting a program and pressing ‘Start’.
  6. To reactivate the child lock, repeat the process of pressing and holding the same button for 3-5 seconds until the key symbol reappears.
  7. Turn the appliance off, wait about 2 minutes, then turn it back on.
