A little residual moisture may be normal, but standing dirty water or repeated overflow needs investigation. Check the model's expected behaviour before removing components.
Table of Contents
Start with these checks
- Read the tray-cleaning section and remove only user-serviceable parts.
- Clear visible debris from permitted filters and rinse the removable tray as directed.
- Refit all pieces and observe the documented wash-and-drain cycle.
What this looks like at home
A filter put back upside down after cleaning can cause trouble even when the tray looks clean.
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
Do not push wire into a pump or use drain cleaner in a robot station.
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
Describe whether the tray contains a normal film of moisture, persistent standing water or an overflow. A photo taken after the cycle ends can help support compare the observation with the model's expected behaviour.
