Liebherr Monolith Message "Connection failure (WLAN)": SmartDevice link switched off

What Connection failure (WLAN) Failure XX0000 means

On Liebherr Monolith MRB, MF and MCB columns such as the MRB 3000, MF 3051 and MCB 3050, the InfinitySwipe panel can display "Connection failure (WLAN)" followed by a failure number in the form XX0000. It means the SmartDevice connection has been disabled. The message concerns the wireless link only and has nothing to do with cooling, so your food keeps its temperature. The instruction on the screen is to contact service.

Common causes of Connection failure (WLAN) Failure XX0000

The SmartDevice connection disabled inside the column
A home network that dropped out or was changed
A wireless part of the column that needs a technician

✓ One safe check you can try

1. Write down the full failure number shown with the message. 2. Check that your Wi-Fi router is on and working for your other devices. 3. Confirm the refrigerator and freezer compartments are cooling as normal. 4. Call us with the failure number to arrange the repair of the wireless link.

! Why to stop there

Cooling is untouched, so food is not at risk, but the disabled connection comes back only through service.
The full failure number tells us what to prepare before we arrive.
Network settings inside a built-in column are not something owners should dig into.

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.

Connection failure (WLAN) Failure XX0000Connection failure (WLAN) Failure XX0000 questions

Does the WLAN connection failure affect cooling on my MF 3051?

No. It concerns only the SmartDevice wireless link. The refrigerator and freezer compartments keep cooling normally while the message is on the screen, so you do not need to move any food.

What should I do when I see it?

Write down the complete failure number, check that your router works, and contact service. The instruction is to call, because the SmartDevice connection has been disabled in the column itself.

Will entering my Wi-Fi password again fix it?

Re-entering a password does not clear a disabled SmartDevice connection. That state needs service. Have the failure number ready when you call so we can plan the visit and give you the price first.
