Technical Details

Repair Steps:

  1. Check for Specific Instructions: The iCombi Pro display may provide specific guidance on how to proceed with the software update. Note any version numbers or specific board references.
  2. Download Latest Software: Access the official RATIONAL service portal or website. Locate and download the latest software version compatible with your iCombi Pro’s serial number.
  3. Prepare USB Stick: Format a USB stick (FAT32 filesystem) and place the downloaded software files directly into the root directory. Do not put them in a subfolder.
  4. Power Down Unit: Turn off your iCombi Pro using the main power switch. Wait for approximately 30 seconds to allow all internal components to fully power cycle.
  5. Insert USB Stick: Carefully insert the prepared USB stick into the designated USB port on your iCombi Pro unit. This port is typically located near the control panel.
  6. Initiate Update: Power on the iCombi Pro unit. The system should automatically detect the software on the USB stick and prompt you to begin the update process. Follow the on-screen instructions precisely.
  7. Do Not Interrupt: During the entire update process, it is critical NOT to turn off the unit or remove the USB stick. Interrupting the update can corrupt the control board firmware, potentially rendering the unit inoperable.
  8. Verify Update: Once the update is complete, the unit will automatically restart. Remove the USB stick. Navigate to the unit’s settings menu to verify that the new software version has been successfully installed and check for the absence of error code 16.
  9. Contact Support: If the software update fails, gets stuck, or the error code persists after a successful update, there may be an issue with the USB stick, corrupted software files, or a faulty control board. In such cases, contact RATIONAL technical support or a certified RestoFixer technician for further assistance.
