Bertazzoni REF18WCB/REF24WCB Codes E5 and E6: Middle Zone In-Cabinet Probe Open or Shorted

What E5/E6 means

On Bertazzoni REF18WCB and REF24WCB built-in wine coolers, such as the REF24WCBPNV and REF18WCBPRV, E5 and E6 report the in-cabinet probe of the middle zone. E5 means the probe circuit is open, and E6 means it is shorted. The buzzer sounds "tic" three times, the code flashes every 10 seconds, and the on/off key silences it. Only one of the two codes is shown at a time.

Common causes of E5/E6

A middle zone in-cabinet probe that has failed open (E5) or shorted (E6)
A damaged lead or loose connector at that probe
Moisture on the probe plug
A control board input that cannot read the middle zone probe

✓ One safe check you can try

1. Press the on/off key to silence the buzzer. 2. Place a thermometer among the middle-zone bottles and read it several hours later. 3. Keep the door shut and avoid frequent opening. 4. Leave the zone settings unchanged. 5. Call us and say whether you see E5 or E6.

! Why to stop there

The probe lead runs inside the cabinet lining, so reaching it means taking apart trim.
A sensor, a lead and a board input give the same code, so the cause cannot be seen.
A zone without a working reading may overcool bottles on a cold night or warm on a hot day.

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.

E5/E6E5/E6 questions

Which zone does this code cover?

The middle zone of the three-zone cabinet. The upper and lower zones have their own codes, so this one points your technician straight to the middle zone probe.

What is the difference between E5 and E6?

E5 is an open probe circuit and E6 is a shorted one. Both leave the control unable to read the middle zone, and the repair is a probe or wiring check.

Can I still store wine there?

Yes, in the short term, with a thermometer to check it. If the reading moves outside the range you want, relocate bottles until we repair it under a written quote.
