Please tell us whether the water in the water tank is distilled water?
The abnormal water level of the washboard has a great relationship with the sealing of the sewage tank.
It is suggested that you operate according to the following to ensure the sealing when pumping sewage:
1. Please remove the cleaning plate, check whether the sewage outlet is blocked and clean it in time, and wipe the overflow sensor of the cleaning plate at the same time;
2. Before reinstalling the sewage tank, check whether the sealing ring of the sewage tank is loose or dirty. Be sure to reset it manually in time, and wipe it with a rag;
3. After dumping the sewage, make sure the sewage tank clips are in place;
4. After the sewage tank is placed in the base station, press down lightly to ensure that the sewage tank is installed in place;
5. You can use a dry cloth to wipe the residual water inside the base, and put the washboard back in and observe it again.
