Possible Causes
Internet connection down, Router blocking Shark servers, Outdated robot firmware, Internal communication module glitch
How to Fix / Troubleshooting
Note: This is typically a connectivity issue, not a hardware failure.
- Check internet: Verify your home internet and Wi‑Fi are working on another device.
- Reboot router: Power cycle your router and modem.
- Reboot robot: Turn the robot OFF and ON again on the dock.
- Update firmware: In the SharkClean app, check for robot firmware updates and apply if available.
If E19 persists only on this robot while other devices are fine, the Wi‑Fi module may be failing.
