Remedy:
Close waste water tank lid. Check waste water outlet and waste water tank for damages and clogging.
Docking station without power supply
Cause:
On-board charger of the robot is not provided with power.
Remedy:
Check if docking station is connected to power socket correctly. Check if power cable of docking station is damaged. Check if there is voltage at the power socket. Check if power connector of the docking port is damaged.
Docking station without water supply
Cause:

Remedy:
Water in docking station tub is not draining. Check docking station for damages and clogging. Check if float switch in the tub of the docking station can move freely and is in good condition.
Docking station clogged
Cause:
Unable to dock in docking station.
Remedy:
Check robot, docking station and surrounding. Remove obstacles.
Docking failed
Cause:
The robot lost its localization.
Remedy:
Drive robot to a position code and start a cleaning task. If the error persists, re-teach the route.
Localization problem
Cause:
Remedy:
An operator cancelled the running autonomous task.
Autonomous task cancelled
Cause:
Teached Smart-Fill area can't be processed.
Remedy:
Teach the route again and avoid complex Smart-Fill shapes (e.g. avoid crossing paths during Smart-Fill).
Smart-Fill failed
Cause:
Remedy:
Bring robot back on designated path.
Robot left designated path
Cause:
Remedy:
Robot finished cleaning task successfully.
Cleaning task finished
Cause:
The robot stopped because its path is blocked.
Remedy:
Check the surrounding of the robot. Remove obstacles on the path.
