Bertazzoni Radiant Ceramic Cooktop Code FH: EEPROM checksum error

What FH means

On Bertazzoni radiant (Hi-light) ceramic cooktops in the PE..CER range, such as the PE304CER and PE244CER, FH means an EEPROM checksum error. The memory chip that stores the cooktop's settings failed its own check, so the control cannot trust its stored data. All heaters are switched off and locked, and the display shows FH until the control is repaired. You will not be able to turn any zone on.

Common causes of FH

Control board memory corrupted
Power surge or outage that disturbed the memory
Board damaged by heat or moisture
Control board that needs to be replaced

✓ One safe check you can try

1. Turn all controls off and let the glass cool. 2. Switch the cooktop off at its breaker for a full minute. 3. Switch it back on and touch the controls once. 4. If FH still shows and the heaters are locked, stop and call us. 5. Please do not open the cooktop.

! Why to stop there

Memory errors live on the control board, which cannot be fixed with a cloth or a reset alone.
The board sits under the glass and carries line voltage.
Parts ordered by guess often prove to be the wrong ones.
We confirm the problem, give a written price and cover the work 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.

FHFH questions

What is an EEPROM checksum error?

It means the small memory that holds the cooktop's settings did not pass its self-check. The control stops the heaters rather than risk running with bad data.

Could a power surge cause FH?

Yes, a surge or outage can disturb stored data. A breaker reset sometimes clears it, but if FH stays or returns, the control board usually needs replacing.

Can I still use some of the burners?

No. With FH all heaters are off and locked. Keep the cooktop off and call us, and we will tell you the price in writing before we begin.
