Bertazzoni Cooktop Code FL: Keyboard Error from Ambient Light

What FL means

On the legacy Bertazzoni induction cooktop P365IME and the radiant PE244CER and PE304CER, FL is a keyboard error tied to the ambient light condition seen by the controls. With the heaters off and locked out, the display shows FL, the zones stay cold, and the keyboard is not accepting commands. It sits in the same F-letter group as the other key errors.

Common causes of FL

Strong or unusual light falling directly on the controls
Dirt, liquid or an object overlapping the keys
A keyboard reading problem that needs service if FL persists

✓ One safe check you can try

1. Check for a bright light or reflection shining straight onto the control area. 2. Wipe the keys clean and dry, and remove anything lying on them. 3. Turn the breaker off for about a minute and restore the power. 4. If FL still appears, leave the cooktop off and call us.

! Why to stop there

The heaters stay locked while FL shows, so the cooktop cannot be used.
The keyboard is under the glass beside live wiring and is not a home repair.
Our price comes in writing first, and the work is backed by a 30-day workmanship warranty.

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.

FLFL questions

What does the light have to do with FL?

The keyboard error on the PE..CER refers to the ambient light condition. If the controls read the surrounding light incorrectly, they cannot trust the key signals, so the cooktop locks the heaters.

Can I try covering the glass?

Moving a strong lamp away or shading direct glare is fine as a quick test. Do not lay anything on the controls. After that, restore the power and see if FL clears.

When is FL more than a lighting issue?

If FL returns in normal room light after cleaning and a power restart, the keyboard or its sensing needs testing. We would diagnose it and give you a written price first.
