Oven display shows F17 and the time or settings cannot be stored; settings reset after power interruptions.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed memory chip on control board, Faulty real-time clock circuit, Internal backup capacitor failure, Firmware corruption

Safety first: Disconnect power before accessing electronics.

User actions:

After a power cut, reset the time and basic settings according to the user manual.
If F17 appears repeatedly without power cuts, internal memory is likely failing.

Service-level fix:

There is no user-serviceable component for the memory; the entire control module must be replaced.
Contact Liebherr service with the model and serial number to obtain the correct programmed module.
