Sorry...yes I knew that chlorine is generated from the salt. Well, it appears that the system has shorted out. They came today to evaluate. They said it could have had a lightning strike, or a power surge...we haven't had a storm or any power surges in quite some time. He said he would send it back under warranty, but not sure they will cover it. There is only one little place on the plug that goes into the box that looked burned. How could just one little spot have had a problem. If it were lightning or a power surge, wouldn't the entire plug be burned? Anyway...they will replace it and I am praying the manufacturer will honor the warranty...60 days of use I sure don't want to purchase another one.
