I have a compool cp3600 and occasionally I notice that the program settings show a garbled time and when that happens I notice that the programs that I set are not working and other things such as the waterfall come on at odd hours. I am frequently having to reset everything and reprogram. I am also having problems with my spa blower starting and staying on. Sometimes I can turn it on and it will work for a little while and then shut off and not go back on.
