How to Fix Error ISP

DIY Fix Check official documentation and model‑specific code list

  1. Locate the specific model number of your LG robot vacuum (e.g., on the body or in the ThinQ app).
  2. Download or open the official user manual for that exact model — many manuals are available at third‑party manual repositories or via LG Support.
  3. Search within the manual for any mention of "ISP" or similar codes.
  4. If the manual shows an error meaning, follow the manufacturer‑recommended troubleshooting steps.

DIY Fix Use LG ThinQ app diagnostics

  1. Open the LG ThinQ app connected to the robot vacuum.
  2. Look for an in‑app error description tied to the ISP indication, which may be more descriptive than the code itself.
  3. If available, follow the suggested steps provided in the app’s diagnostic tools.
🛑 When to Call a Pro:
  • If the ISP indication persists after basic diagnostics and cleaning, contact LG customer support with the model number and error details.

Next step

Choose the next step for ISP

Confirm the diagnosis before ordering. An error code can identify the system involved, but it does not prove that a specific part has failed.

Model number required

Browse by model — no specific failed part is claimed

Model-compatible Robot Vacuum parts

Enter the complete model number to browse compatible replacement parts. This is a model-based parts search, not a diagnosis that a specific component failed.

Where can I find the model number?

Check the rating label around the door, lid, frame, rear panel, or inside the appliance cabinet. Use the complete model number, including suffixes.

Find a part that fits my model

Search results are not a diagnosis. Verify both the complete appliance model and the retailer's fit information before ordering.
