What ALL Power cut Means
On the ProfiPremiumline text display a power failure is reported as ALL Power cut, alternating with the standard indication. Liebherr puts it in the group of alarms that require the stored items to be checked, and the controller keeps both the duration of the interruption and the maximum temperature reached inside the cabinet.
Common Causes of ALL Power cut
- A mains interruption affecting the premises or the circuit the cabinet is on
- An isolator, breaker or plug switched off during cleaning or maintenance
🔧 One Safe Check You Can Try
Before deleting the message, call up the saved alarm event so you have the length of the outage and the peak temperature. The alarm memory is reached through the alarm menu, and Liebherr warns that the alarm display is deleted automatically once it has been queried — so read it once and record it.
⚠ Why You Shouldn't Go Further Than That
- The controller gives you duration and peak temperature together, which is exactly the pair of figures a food-safety decision needs, and both disappear once the query has been made.
- Repeated power-cut alarms with no known outage indicate a supply problem in the premises, and that is an electrical investigation rather than a refrigeration one.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
