    Start with checking the S1 coil for magnetizem with the controller in the lower/float position. This will tell you if the signals getting to the coil. If it does have it, pull the valve out and see if you can push it in with a small screwdriver..

    If it doesn't have magnatizem, start checking connections from the controller to the coil.

    The S1 coil is the one with the white/yellow wire.

    Be very careful when doing this test as the blade could drop unexpectedly!
