Technical support and warranty

Report a fault or a warranty claim. You receive a ticket number by email, and our team follows up by email or WhatsApp.

How it works

  1. Send the form with the serial number, proof of purchase and photos.
  2. You get a ticket number by email. Quote it in all messages.
  3. We review the case and may ask for logs, more photos or a remote check.
  4. We agree the solution: remote fix, repair or replacement under the manufacturer's warranty.

Before you start

  • Serial number
    From the label on the unit
  • Proof of purchase
    Invoice or delivery note
  • Photos
    Serial label, error screen or damage
  • Error code

For safety, switch the system off following the manufacturer's instructions if you see smoke, burning smell or physical damage.
