Most Common Issues on This Model
01
Control panel showing an F-series or S-series error code — Liebherr documents the problem ranges but reserves the specific-digit meaning for a technician's own service lookup, so we read the exact code before opening anything
02
DEMO mode left switched on, leaving the display live with the cooling circuit switched off
