TLDR

On your BAKERLUX SHOP.Pro unit, error E12 indicates a network communication failure, preventing the oven from connecting to the cloud services. This is typically caused by a firewall blocking outgoing HTTP traffic on TCP port 80, or an incorrectly configured network gateway. Contact your network administrator to verify network settings and firewall rules.

Technical Details

Repair Steps:

  1. Initial Network Verification: Begin by restarting both your UNOX BAKERLUX SHOP.Pro oven and all relevant network equipment, including your router and modem. Verify that the oven’s network cable (if applicable) is securely connected and that any network indicator lights on the oven or switch are active.
  2. Check Oven’s Network Configuration: Access the network settings menu on your UNOX oven. Confirm that the IP address, subnet mask, gateway, and DNS server settings are correct for your local network environment. If using DHCP, ensure the oven is receiving a valid IP address.
  3. Firewall Configuration Check (Network Administrator): This is a critical step. Engage your network administrator to verify that the network firewall is not blocking outgoing HTTP traffic. Specify that the oven communicates via TCP on destination port 80. The firewall must permit this specific outbound connection for cloud services to function.
  4. Gateway Configuration Check (Network Administrator): Have your network administrator confirm that the configured network gateway is correct and actively forwarding traffic to the internet. An improperly configured or malfunctioning gateway will prevent the oven from reaching external servers.
  5. Verify Unox Cloud Service Status: Occasionally, the issue may stem from the Unox cloud service itself. Check the official Unox website or status page for any reported outages or maintenance affecting their cloud platform.
  6. Contact Technical Support: If all network configurations appear correct and the Unox cloud services are operational, but the E12 error persists, contact your certified Unox service technician or Unox technical support for further diagnosis.
