Bertazzoni P365IAE Cooktop Code Er47: Hob Not Connected to the Network

What Er47 means

On the legacy Bertazzoni induction cooktops P304IAE and P365IAE, Er47 means the hob is not connected to the network. The instruction is to check the connection and reconnect the hob. Here, network means the electrical supply. The cooktop does not get proper power, so it stops. Owners see Er47 after switching on, or after a breaker trip. Nothing is wrong with the zones themselves, only the connection to power.

Common causes of Er47

The cooktop's supply connection is loose or interrupted
A breaker that is off or has tripped
A wiring problem at the supply side

✓ One safe check you can try

1. Check that the cooktop's breaker is fully on. 2. Reset it once if it has tripped. 3. Switch the cooktop on again. 4. Do not try other outlets or breakers; the cooktop is hardwired and needs a proper check. 5. If Er47 returns, stop and call us so the connection can be checked.

! Why to stop there

A supply problem can hide a wiring issue, so repeated attempts are not wise.
Checking the connection means working at the 240V terminals.
We give a written price first, and our work has 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.

Er47Er47 questions

Does network mean Wi-Fi?

No. On this cooktop it refers to the electrical supply connection. Er47 means the hob is not properly connected to its power supply. The fix is therefore about the power feed.

What should I check first?

Check the breaker for the cooktop. If it has tripped, reset it once and turn the cooktop on again. If it trips again, leave it off and call us.

Could a loose wire cause Er47?

Yes, a loose or interrupted connection is the typical reason. Because it sits at the supply terminals, a technician should check it rather than the owner.
