Quick answer
F08 — commonly associated with a heating/flow issue on a Bertazzoni dishwasher. Meaning can vary by model; verify before relying on it.
Model compatibility: Bertazzoni reuses codes across series and model years, so F08 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
Homeowners usually see F08 on a Bertazzoni dishwasher in connection with a possible heating, flow or limescale-related problem. Independent technicians still match the code to your serial family before ordering parts. Two Bertazzoni units can share a display string yet mean different subsystems; verify for your serial family.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Run a descale cycle if the machine indicates one is due
Confirm the water tank is filled and correctly seated
Perform a manufacturer-approved restart
Keep notes on any recent power outages, filter changes, or installs before the visit
Important safety warning. Do not open internal panels, access high-voltage wiring, or bypass any safety device. If you see smoke, sparks, a burning smell, or water near electrical parts, switch the appliance off at the outlet if it is safe to do so and call a professional.
Please avoid
What not to attempt

When to call a technician
When F08 returns after one careful reset, pause DIY cycling and schedule Bertazzoni Appliance Repair. Bring photos of the code and the rating plate.
Seeing this code on your Bertazzoni appliance?
Book a specialist visit for a clear estimate and approval before any repair. Independent service — not an official Bertazzoni service center.
You can safely try the basic checks above and one manufacturer-approved restart. If F08 returns, book Bertazzoni Appliance Repair rather than repeating resets.
Control generations differ. Treat F08 as a starting clue, then confirm the exact definition for your serial family before parts.
No. Bertazzoni Appliance Repair publishes independent repair guidance for homeowners. Use your Bertazzoni model manual for manufacturer wording, then book an independent technician if the fault continues.
