What if there is no water in the balance ring of automatic washing machine?

Hello, just for reference. I hope you can help me. I understand the balance ring of automatic washing machine as the balance ring of automatic washing machine. The balance ring is heated by hot melt technology, so that the upper and lower plastic rings are fused together, and there is generally no way to add leakage. You can contact a special washing machine maintenance point, and only the balance ring can be replaced.
