Bertazzoni PE304INDXV Cooktop Code Er: Display and Mainboard Not Communicating

What Er means

On Bertazzoni professional induction cooktops such as the PE244INDXV, PE304INDXV and PE365INDXV, Er means the communication between the display and the mainboard has failed. The official instruction is to contact customer service or a licensed electrician. Owners see Er and a cooktop that does not accept settings or heat. The code replaces the usual display, and the zones do not respond to the controls. Owners may find the cooktop completely unresponsive.

Common causes of Er

A communication failure between the display and the mainboard
A loose or damaged link between them
A display or board that needs replacement

✓ One safe check you can try

1. Switch the cooktop off and turn its breaker off for a minute. 2. Restore power and see whether the display recovers. 3. Keep the glass dry, with nothing resting on the controls. 4. If Er returns, stop and call us.

! Why to stop there

When the display and board cannot talk, the cooktop cannot take commands safely.
The link is under the glass, close to live voltage.
We quote in writing first, and the repair carries 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.

ErEr questions

What does Er tell me?

It tells you the display and the mainboard are not exchanging information. The control cannot be sure what you are asking, so it holds back instead of heating.

Will a power reset help?

A single reset is safe to try. If Er returns, the communication problem is real, and a licensed electrician or our technician should look at the link.

How is Er different from E-codes?

E-codes with a number name a specific condition such as voltage or temperature. Er is about communication between the display and mainboard, so the test starts there.
