Bertazzoni Radiant Ceramic Cooktop Code F5: Communication error

What F5 means

On Bertazzoni radiant (Hi-light) ceramic cooktops in the PE..CER range, such as the PE304CER and PE244CER, F5 is a communication error shown on the heater display. Two parts of the cooktop control are not exchanging data the way they should. The code clears by itself when communication is working again, so you may see it only briefly after power returns or when the touch panel is wet.

Common causes of F5

Brief interruption in communication between the touch panel and the power board
Moisture or spills on the touch panel
Loose internal connection after the cooktop was moved or serviced
Control board that cannot keep communicating

✓ One safe check you can try

1. Turn all heaters off and let the glass cool. 2. Wipe the touch panel dry with a soft cloth and remove any spills. 3. Switch the cooktop off at its breaker for one minute, then on again. 4. Touch the controls and see whether F5 is gone. 5. If F5 returns or the heaters do not respond, call us.

! Why to stop there

A code that comes and goes is hard to catch without a test.
The connections between the panel and the power board sit under the glass, near line voltage.
Replacing boards at random is costly.
We give a written price before any work and warrant the repair for 30 days.

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.

F5F5 questions

Does F5 clear by itself?

Yes, when communication returns to normal the code disappears. If it comes back again and again, or it stops the heaters, the cooktop needs a proper check.

Can a wet panel cause F5?

Water or spills on the touch glass can disturb the signal and trigger a communication error. Dry the panel and try again before assuming the cooktop is broken.

Which cooktops use this F5?

This meaning is for the radiant ceramic PE..CER models such as the PE304CER and PE244CER. Induction cooktops use different codes, so read the display of your own model.
