I have an Intex ECO20110-2 Sand filter with saltwater chlorinator. Not one single issue last, the first year in use. Yesterday I set the pump and filter system up because my water had a lot of gunk and I needed to get it shocked and vacuumed. Everything worked fine. Left it in full pump mode, with the chlorinator off, all afternoon and night. This morning I started vacuuming the gunk off the bottom and everything was fine. For a while. I noticed there was no suction and very little outflow. And then the Code 90, low pump flow light and beep. So far not a darn thing suggested by many has helped. Nothing. I've changed out the brand new sand. I've pulled the impeller. Checked for air. Turned skimmer on and off. NOTHING. I keep reading about a Low Flow Switch but nowhere can I find where it is located. I'm about ready to toss the whole Dang mess in the trash. PLEASE. ANY HELP??
