I have a Pentair iChlor30salt generator that is 3 years old. When I power on The flow light turns red then goes off and the salt led turns green then red and goes off. After this no Leds are on and it’s like the unit has no power. The greened is on, on the power board so it’s not the 10a fuse. What is causing it to do this? No response to any of the buttons on generator touchpad.
