The KPesf 4220 Comfort is the larger sibling of the KPesf 3620, same freestanding all-refrigerator format and Comfort-tier control, just with more interior capacity.
As with most models in this Comfort-tier line, the calls we get are either a specific F-prefixed code on the panel or a demo setting left active from setup — both confirmed off the display before deciding what, if anything, needs replacing.
Key Features
- Freestanding all-refrigerator cabinet
- Comfort-tier electronic temperature control
- Standard Liebherr error code diagnostic display
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
DEMO mode left switched on from setup or a showroom display, leaving the panel lit with no active cooling
