Bertazzoni REF18WCB/REF24WCB Codes E1 and E2: Upper Zone In-Cabinet Probe Open or Shorted

What E1/E2 means

On Bertazzoni built-in wine coolers REF18WCB and REF24WCB, such as the REF24WCBPNV and REF18WCBPRV, E1 and E2 are linked codes for the upper zone in-cabinet probe. E1 means the probe circuit is open, and E2 means it is shorted. The buzzer sounds "tic" three times, the code flashes every 10 seconds, and the on/off key silences the buzzer. Only one of the two codes appears at a time.

Common causes of E1/E2

An upper zone in-cabinet probe that has failed open (E1) or shorted (E2)
A damaged probe lead or loose connector
Moisture at the probe or its plug
A control board input that cannot read the probe

✓ One safe check you can try

1. Press the on/off key to silence the buzzer. 2. Put a thermometer among the bottles in the upper zone and read it after a few hours. 3. Check that the door closes fully and the gasket is clean. 4. Avoid changing the zone setting while the code is showing. 5. Call us and tell us whether the display shows E1 or E2.

! Why to stop there

The probe is built into the cabinet lining, and the control that reads it carries live voltage.
A bad probe, a damaged lead and a failed board input all produce the same code.
Without a reading, the upper zone can run too warm or too cold for your wine.

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.

E1/E2E1/E2 questions

What is the difference between E1 and E2?

E1 means the probe circuit is open, as though the wire were cut. E2 means it is shorted, as though the two wires touched. Both say the control cannot read the upper zone, so the repair path is similar.

Is my wine safe?

Probably, for a few days. Place a thermometer in the upper zone and watch it. If the reading drifts away from your setting, move valuable bottles to another cool, dark place.

Why does the code flash every ten seconds?

It keeps reminding you after the buzzer has been silenced. The code only clears when the probe is repaired or replaced, which we do after quoting the price and confirming the cause.
