Freezer shows F17; may be related to SmartDevice or network connectivity issues.

Safety first: Disconnect power before inserting or removing SmartDevice modules.

Steps:

• Remove SmartDevice module: Open the SmartDevice slot (usually on the top of the appliance) and carefully remove the module.
• Inspect contacts: Check the module and slot contacts for dust or corrosion. Clean gently with a dry, lint-free cloth.
• Reinsert and reset: Reinstall the module firmly, restore power, and follow Liebherr's pairing/reset instructions.

Remedy: If F17 persists, replace the SmartDevice module. If a new module does not resolve the error, the main control board's communication interface may be faulty.
