Washboard overflowing

Guys my dreame robot isn’t draining the dirty water and it goes into the wash board causing it to overflow with dirty water.
I’ve already tried going to dock setting and cleaning the dock manually and it drains it but when I mop the floors and it washes the mop pads it leaves a puddle of dirty water. Please help.

Hi,
Please try the following troubleshooting steps.

1. Remove the washboard and check if the sewage outlet is blocked. If it is blocked, please clean it thoroughly.
2. Wipe the overflow sensor on the washing board to ensure there is no dirt or debris.
3. Carefully remove the used water tank and check if the  used water tank sealing ring is loose, dirty, or turned up. If the sealing ring is dirty, reinstall it and wipe it clean with a cloth to ensure it is firmly installed. If the sealing ring is turned up, please provide a photo of the abnormality.
4. After emptying the sewage in the used water tank, ensure the buckle is fixed and the used water tank is firmly installed in place to prevent leakage during operation.
5. Reinsert the used water tank into the base. Gently press it down to ensure it is correctly and firmly installed.
6. Use a dry cloth to wipe off the residual water in the base station. After cleaning, reinstall the washboard and check if the issue still exists.
