The station may be responding to a mis-seated tank or level mechanism rather than actual water volume. Inspect the removable tank before restarting repeatedly.

Start with these checks
- Empty and rinse the tank as the manual permits.
- Check its lid seal and accessible float are clean and correctly positioned.
- Refit firmly, then retry the documented wash or recovery function.
What this looks like at home
A float caught by dried debris may continue reporting full after the water has been poured away.
Keep clean water, dirty water and dry dust separate
| Check | What matters |
|---|---|
| Clean-water side | Use the permitted water and solution method. |
| Dirty-water side | Empty and clean the removable tank as directed. |
| Pads, roller and tray | Inspect, clean and dry only as the manual allows. |
A mistake to avoid
Never operate with a tank lid deliberately unsealed to suppress a warning.
Buy a part only after identifying the cause
Check the exact model and part reference before buying. If cleaning resolves the problem, a replacement may be unnecessary.

What the result tells you
Record whether the warning appears immediately after insertion or only when the dock tries to recover water. That timing can be useful when support checks tank seating and the documented level-detection components.
