Dear user,

We apologize for the inconvenience you are experiencing.

To troubleshoot the issue, please follow the steps below:

1. **Check the Waste Tank**:

- Remove the waste tank and inspect the sealing ring for any deformities or improper installation . If it is deformed or not properly installed, reset the sealing ring manually. If the waste tank is broken, please contact us.

2. **Reinstall the Waste Tank**:

- Ensure the waste tank is in normal condition. Secure the cover of the waste tank, reinstall it, and press down to ensure it is correctly positioned.

3. **Clean the Washboard**:

- Press the clips on both sides of the washboard to remove it. Pour out any wastewater and check if the filter is clogged. If so, clean it.

4. **Dry the Base**:

- Wipe any residual water in the base with a dry cloth. Reinstall the washboard and secure the clips on both sides (refer to attached video).

5. **Test the System**:

- Using the app, click "clean mop pad" and check if the error persists.

If the problem continues, please do not hesitate to contact us(support.na@dreame.tech) again.

Thank you for your understanding.

Me too. Even after cleaning everything and checking everything is good, I get the same message. Very frustrating yo say the least.
