My filter - pump does not turn on. All functions on the display are working and the light button on the display panel does turn the lights on in the pool. When I press the filter button to turn on the filter it just clicks. The circuit board is ok and no burn spots - fuses ok - checked all power and power to the pump is ok. Shut main breaker off and waited 1 minute and turned back on but still same problem. Check system light is on as salt level was at 2000 ppm - added salt to pool because I heard that Aqua Logic will turn off if salt is real low. Still filter does not turn on after adding salt. Could the problem be with pump itself? If so, should I at least hear the pump attempting to run? I still think it has something to do with the board but everything checks out ok. Can anyone help???
