I have unplugged to reset several times to no avail. Still getting the low temp light and my water is 68 degrees. When I push the more button for 3 seconds, it shows 20%, then when I press it again, the 40% and 60% lights are on. Is there any way to tell if this is a flow switch issue. This is my 2nd IC40. Pool installed in 2010, and the first SWG died in April of 2016, so this one that I bought on Amazon only has 2 years of use.
