    Ecomatic ESC 36 does not turn on with water flow.

    Hey Everyone,

    I moved into a house three years ago with a 20k-25k gallon pool. The pool has an Ecomatic ESC 36 system. Every day (after the pump is already running) I have to go outside and flip the Ecomatic off and back on to get it to produce chlorine. Before I flip the switch the two lights are green and the small red light under where the number would be is on (indicating FLOW). A minute after I flip the switch off, then on, the numbers start up and go to 100, to show it is producing chlorine. It then will work all day. If I don't flip the switch though, it never has numbers on the screen and just stays with the two green lights and the FLOW indicator on.

    Troubleshooting and reading others tips online I have replaced the cell with a new one (last year), replaced the wires to the cell (old owners dog had chewed on them), upped the salt to between 4500-5000, but still nothing has worked. The pump is a 1hp pump, so it produces plenty of power to the cell. The only thing I have not done is replace the actual Ecomatic that is mounted to the wall because I figure it works fine when I flip the switch. Any one have any ideas???

    I'm not familiar with that system, but does it have a separate flow switch or is it integrated into the cell? Hopefully someone who has one can help out..

    The switch is on the "Power Pack," which is separate from the cell.
