F5 is a pressure system failure with a single printed action: contact service.
Model compatibility: Bertazzoni reuses codes across series and model years, so F5 / F05 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
F5 is a pressure system failure; the manual says to contact service.
Bertazzoni’s fault table gives F5, which some lists print as F05, just two cells. Under fault it says pressure system failure. Under action it says contact service.
Reading the words pressure system
Knowing the amount of water in the tub is essential for a dishwasher, and a pressure sensor is a common way of measuring it. Elsewhere in Bertazzoni’s manuals, the E1 slow-fill entry lists a pressure switch among its checks. The F5 line names nothing specific, so the wording describes a whole system and not a single component.
Safe steps
End the program and turn the dishwasher off.
Leave it off. Starting it again in the hope that the code vanishes is not recommended.
Leave these alone
Do not pull off panels or hoses searching for a sensor. The manual gives no part details, so there would be no way to know what you are looking at.
Common questions
Does the manual say more? The manuals in this group give F5 a single line, so nothing further can be read.
Is F5 a version of E1? No. E1 describes a fill that took too long and lists seven checks, while F5 lists no checks at all.

Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
