Lower wine-zone air sensor fault.
Model compatibility: Liebherr display alerts can vary across series and model years, so BT013 may mean something different on another appliance or generation. Confirm it against your model documentation and record the full model number before acting.
What this code means
Lower wine-zone air sensor fault.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
Frequently asked questions
BT012 concerns the upper wine-zone air sensor; BT013 concerns the lower wine-zone air sensor on multi-zone platforms that include both.
Yes. Lower-zone sensor faults can present while another zone still holds temperature, which is why zone-specific notes matter.
If lower-zone temperature is drifting or the alert repeats, arrange diagnosis promptly rather than waiting on repeated resets.
