The KB 4210 Comfort BioFresh is a freestanding, single-cabinet refrigerator — no freezer — with a BioFresh drawer added onto Liebherr’s Comfort-tier control for near-0°C, high-humidity storage of meat, fish, and produce.
Two things bring most owners to call: the panel showing an F-prefixed code, or the BioFresh drawer refusing to settle into that near-0°C range. We narrow down which one it is before opening the cabinet.
Key Features
- Freestanding all-refrigerator cabinet with BioFresh

- BioFresh compartment for near-0°C, high-humidity storage of meat, fish and produce
Most Common Issues on This Model
01
Control panel showing an F-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
BioFresh compartment not settling into its near-0°C, higher-humidity range
