Before you book,
in this order.

Each step comes from Liebherr's own guidance for F1 to F5 on its refrigerators. Follow it to the end: the last card says whether this is a visit.

01

Write down the exact number shown (F1, F2, F3, F4 or F5).

02

Find the type designation and service details, and have them ready along with the number.

03

Check whether the compartments are still holding temperature.

Still there?

It usually turns into diagnostic visit. Book with the code and the model number.

What not to do

Be wary of lists online that assign each F number to a particular sensor. Liebherr's own manual does not decode them.

Questions
about F1 to F5.

Can I clear F1 to F5 myself?
Write down the exact number shown (F1, F2, F3, F4 or F5). If it comes back, it needs a visit.
What does F3 mean on my Liebherr, specifically?
Liebherr's manual does not break the F1 to F5 numbers down individually. It asks you to have the number ready for customer service, who interpret it. Treat online lists matching each number to a sensor with caution.
What should I have ready before calling about F1 to F5 on a Liebherr?
The exact number shown, the type designation and the service details from the appliance. Also check whether the compartments are holding temperature, since that shapes how soon the visit is needed. This applies to the CS 1640 NoFrost; other Liebherr controls differ.
