Troubleshooting guide
How to fix the problem
This message may indicate residual water, a contaminated detection area, or non-vacuumable wastewater. It does not confirm the failure of one particular pump. If the tray is full, do not start a new wash.
Possible solutions
Choose the method that matches your situation. Start with the simplest suitable option and check the result. If the problem is fixed, you do not need to continue with the other methods.
Cleaning the tray and its filter
Use the L10s Ultra Care Scheme specifically.
Steps to follow
- Stop the task and disconnect the power to the base if it is safe to do so and the electrical connections are dry.
- Remove the remaining water from the tray according to the instructions and remove the consumer filter.
- Remove hair and mud and clean the water detection area indicated in the instructions.
- Assemble all parts in their places, making sure there are no leaks under the base before connecting.
The tightness of the wastewater tank
Without a sealed tank, the pump may not draw water.
Steps to follow
- Empty the dirty water tank and inspect the cover gasket.
- Clean the sealing surface and close all the provided latches.
- Insert the tank all the way and only check one normal cycle if it is safe.
- If water remains again or the base overflows, turn off and report the error screen and tank status to service.
Features, menus and error codes depend on the exact robot and dock model and software version. Instructions for another series may not apply.
If the problem persists
If the message remains with the clean tray properly inserted and the waste tank sealed, water level and suction diagnostics are required. Do not disconnect the sensors to hide the water level.
Request a repairBefore you begin: Before maintenance, stop and switch off the robot and unplug the dock. Do not touch moving parts during operation. If liquid reaches electrical components or the battery is damaged, do not power the device on again until it has been inspected.
