Bertazzoni REF24BMBPNB Bottom-Mount Code EC: Display Panel Link Problem

What EC means

On the Bertazzoni REF24BMBPNB-type bottom-mount refrigerator with its display-and-alarm panel, code EC appears on the temperature display when the main board and the display panel stop communicating. The appliance still cools, but a technician should check it. You will see EC on the display, possibly with an alarm tone, and temperature adjustments may stop working. Until the link is restored, the panel may ignore your key presses.

Common causes of EC

A loose connector or cable between the display panel and the main board
A display panel that no longer sends or receives data
A main board whose communication circuit has failed
A voltage spike that interrupted the link between the boards

✓ One safe check you can try

1. Check that the refrigerator and freezer are still cold. 2. Press the alarm key if the buzzer is sounding. 3. Turn the breaker off for about a minute and switch it back on. 4. Give the controls a few minutes and watch whether EC returns. 5. If it does, keep the doors shut and book a visit.

! Why to stop there

The display and the board share a ribbon or wire harness behind the control housing, which is not safe to open at home.
Resetting repeatedly hides a loose connector until it fails completely.
Replacing a board without testing the link first often leaves EC on the screen.

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.

ECEC questions

Is my food at risk with EC on the display?

Not right away. The cooling continues, and the code only says that the panel and the board are not communicating. Check temperatures by feel and thermometer for the first day.

What is the difference between EC and a sensor code?

A sensor code names a temperature probe. EC concerns the data link between the display panel and the main board, so the cause is in the electronics or the cable, not in a probe.

Will a reset clear it for good?

Only if the cause was a one-time glitch. If EC returns after the reset, a connection or a board is failing, and we would test it and quote the work before starting.
