I have a Vita Spa L780C which is 6 months old. It's well maintained but started giving error messages (HI LI) which my manual says means overheating... (not really the case as it only reached about 98 degrees). Also, (Pb) message appeared and blinking at an erratic pace (not consistent timely blink). I have turned power off each time in hopes it would remedy itself. Each time it starts fine and runs normally for 4-24 hours and the problem starts again. The last time, it started kicking the pumps on and off quickly which sounded pretty unhealthy for the pumps. My concern is when I get a tech. out here s/he will see it functioning normally (unless I leave it on and possibly in a self destructive state)
Any suggestions?
