Robot mower displays E17 and stops; often associated with GPS or Wi‑Fi models.

Safety first: This is a connectivity issue; no special physical safety steps beyond normal handling are required.

Steps to check:

• Wi‑Fi signal: Ensure the router is within range of the charging base. Consider moving the router or base, or using a Wi‑Fi extender.
• Network settings: Confirm the network SSID and password are correctly entered in the Worx Landroid app. Ensure the router is not blocking the mower (MAC filtering, firewall).
• Update app/firmware: Install the latest Worx app and check for mower firmware updates.
• Re-pair device: Remove the mower from the app and re-add it following the pairing instructions.

When to call a technician: If E17 persists with strong Wi‑Fi and correct settings, the internal Wi‑Fi module may be defective and require service.
