My sun can turn the tap into cold water. Why is there no water when there is water, and it becomes hot water? Is the water pipe frozen? What should I do?

It should be frozen. My home is over 60 degrees, and the hot water still doesn't come out. Let's call Sang Le after-sales endlessly. We have been calling for more than a month, but now no one cares about us, so they call us back halfway, saying that it is cold this winter and many of them are frozen, saying that it can't be solved. Look, I'm angry. As far as the weather in Shijiazhuang is concerned, the lowest temperature is only MINUS ten degrees. The weather was fine last year. Besides, if you are frozen, you can't solve what we can. I didn't say it would freeze in winter when I bought it. The technical department at headquarters called and asked them that it was okay to have a temperature of MINUS 40 degrees. As a result, no one cares about my house now, no one cares. As for the after-sales service in Sang Le, how to sell things and how to advertise? We are all a group of deceived people. .
