  2. Inspect the lid's plastic hooks to rule out breakage.
  3. Clean the lid sensor contacts with compressed air or a dry cloth.
  4. Close the lid firmly, ensuring both sides engage properly.

Prevention and Maintenance

Regularly clean the hinges and locking hooks to keep the mechanism smooth. Use only original consumables to avoid putting unnecessary strain on the lid.
