A couple of years ago I was having a CELL POWER issue and ending up replacing my GLX-PCB-MAIN pcb board. It has worked great until a month or so ago.
Now, the time is not advancing so my pump never turns on at the scheduled time. I have to manually turn it on and off.
Hayward states that the problem is again with the GLX-PCB-MAIN board.
Has anyone ever had this problem?
