Please help. My three-week-old Aquatrol was working beautifully and then it blew the 20 amp fuse inside. I replaced the fuse and all seems to work; however, where the salt quantity is normally displayed, it reads HOT. I'm not sure what to do. I unplugged the unit for several hours to see if it would cool off, but when I plugged it in, it immediately read HOT. The unit does not feel hot and the water is not hot. Any ideas? Thanks.
