We just recently purchased a 2012 Optima and I'm confused about the filter cycle. I have it set on standard and the filter cycle is set to start at midnight and run for 12 hours(that's just what it was set to when we got it). However, when I go check it around 8AM it's not running and so far I haven't seen it run at all except when we first plugged it in and it heated up the water.
I've read in the manual that a summer logic can occur if the tub gets 2 degrees over the set temp. I have it set at 94 and it's hot here so it's very possible it's hitting that condition in the middle of the night, but when I look at it in the morning, it still reads 94. My question is, once it hits summer logic does it just skip the rest of the filter cycle? I don't see that anywhere in the manual, but that seems like it might be what it's doing.
I actually tried to modify the duration of the filter cycle this afternoon and after I had increased the duration to 14 hours it kicked on. So that makes sense, but I'm not sure why it wasn't on anytime after 8AM.
