If your MACH V1 vacuum cleaner's clean water tank is leaking, please try the following troubleshooting steps to verify if the issue can be resolved:

1. Check whether the water level exceeds the maximum limit. Also, please check if there are water stains on the water tank surface and use a clean cloth to wipe it dry.

2. Check if the clean water tank is installed properly. Please make sure the water outlet is aligned with the connector of the vacuum cleaner.

3. Remove the water tank and check if the rubber cover on the water tank is installed properly. The surface should be smooth if the rubber cover is completely sealed.

4. Reinstall the clean water tank. The clean water tank will make a clicking sound when it is properly installed and locked in place.
5. Power on the vacuum cleaner and check whether the clean water tank is still leaking water.
