Liebherr NoFrost Code F1-F5: the appliance reports a failure, give us the number

What F1-F5 means

On Liebherr US NoFrost combined units with an IceMaker, including the HCB 1560, HCB 2062, CBS 2062, HC 1570G and HC 2090G, an F-number between F1 and F5 appears in the display when the appliance detects a failure. The instruction is to give that number to customer service. No list explains each digit to owners, so the exact number you read is the key piece of information for us.

Common causes of F1-F5

An internal failure detected by the appliance and shown as an F-number
A control or sensor problem that a technician pins down on site
A cooling system problem that needs instrument testing

✓ One safe check you can try

1. Read the F-number carefully and write it down. 2. Turn the unit off, wait a minute, and turn it on to see whether it returns. 3. If it does, keep the doors closed and protect your food by using coolers if needed. 4. Book a visit and tell us the number.

! Why to stop there

We cannot read the cause from the digit alone; a technician checks the unit directly.
Testing needs instruments and means opening sealed or electrical areas, which is unsafe for owners.
Our repairs include a written price first and a 30-day workmanship warranty.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F1-F5F1-F5 questions

What does F3 mean on my CBS 2062?

The display is telling you the appliance has a failure, and F3 is the number to pass on. There is no owner-level list for single digits, so we read the cause on site.

Will turning it off and on fix an F-number?

Not on its own. A restart tells you whether the failure comes back. If the number returns, the problem is real and needs a technician rather than more resets.

What should I tell you when I call?

Give us the exact F-number, the model such as HCB 2062, and whether food is staying cold. With those three facts we can plan the visit and tell you the price beforehand.
