The sewage in the station cleaning sink cannot be recycled; how to deal with the voice alarm "cleaning sink full"?

Case 1: Voice Alarm "Cleaning Sink Full"

Open the station panel and remove the sewage tank.
Open the top cover of the water tank and confirm that the sealing ring is properly assembled. Let it stand for about 10 seconds, then close the cover again.
Remove the sealing plug, clean it, and reinstall it. Put the sewage tank back into the station and press it down firmly.
Press and hold the station panel button for about 3 seconds, and check if the sewage starts recycling.
If recycling still fails:
- Remove the cleaning sink filter assembly and clean the suction port to remove any foreign objects.
- Reinstall the filter assembly, press and hold the station panel button for another 3 seconds, and observe the recycling process.
- If the issue persists:
- Remove the base to manually pour out the sewage.
- Clean and wipe the overflow sensor with a tissue.
- Reattempt self-cleaning and observe the system.

Case 2: No Water Alarm in the Cleaning Sink

Turn off the power to the station.
Remove the cleaning sink filter assembly and use a tissue to clean the overflow level sensing pieces on both sides of the sink.
Power the station back on and observe it.
