CARTA 3 — 505 Error Code – Atomizer Disconnected

Updated Oct 13, 2026 3 min read

If your CARTA 3 displays Error 505, this indicates a connection issue between the INTELLI-CORE 3 Atomizer and the connection pins inside the CARTA 3 base. This error means your device is having difficulty detecting or communicating with the atomizer, which may prevent it from heating properly. Fortunately, there are a few troubleshooting steps you can take before contacting our support team.

Check for Firmware Updates

Before inspecting your device, make sure your CARTA 3 is running the latest firmware.

  1. Power on your CARTA 3 and open the V Browser app.
  2. Connect your CARTA 3 to the app.
  3. Check for any available firmware updates.
  4. If an update is available, follow the on-screen instructions to install it. Once the update is complete, check whether Error 505 continues to appear.

Deep Clean the INTELLI-CORE 3 Atomizer

If updating your firmware doesn't resolve the issue, we recommend thoroughly cleaning your INTELLI-CORE 3 Atomizer and the connection pins inside your CARTA 3 base.

  1. Power Off and Cool Down: Turn off your CARTA 3 and allow the atomizer to cool completely before handling it.
  2. Remove the Atomizer: Carefully unscrew the INTELLI-CORE 3 Atomizer from the CARTA 3 base.
  3. Clean the Connection Pins: Using a cotton swab lightly dampened with 90% isopropyl alcohol, gently clean the connection pins on the bottom of the atomizer.
  4. Remove Silicone Components: Carefully detach any removable silicone components from the atomizer.
  5. Clean the Atomizer Chamber: Using a cotton swab lightly dampened with 90% isopropyl alcohol, gently wipe the inside of the atomizer chamber to remove any visible concentrate residue.
  6. Soak the Atomizer: Submerge only the atomizer in 90% isopropyl alcohol for approximately 5 minutes. Gently agitate the alcohol to help loosen stubborn residue.
  7. Clean the Base Connection Pins: While the atomizer is soaking, use a fresh cotton swab lightly dampened with 90% isopropyl alcohol to gently clean the connection pins inside the CARTA 3 base. Carefully remove any visible residue or buildup around the pins, avoiding excessive liquid contact with the base's electronic components.
  8. Allow to Dry Completely: Remove the atomizer from the alcohol and allow it to air-dry completely. Inspect for any remaining residue and repeat the cleaning process if necessary. Make sure the base connection pins are also completely dry.
  9. Reassemble the Atomizer: Once everything is completely clean and dry, reattach the silicone components and reinstall the atomizer into the CARTA 3 base until snug, without overtightening.

Test Your CARTA 3

Once your atomizer and connection pins are completely clean and dry, power your CARTA 3 back on and attempt another heating cycle. If Error 505 no longer appears, your device should be ready for normal use.
