    I have a 7 station ESP-M controller that has 4 stations on the main module and 3 stations on an expansion module. All has been working correctly for the past few years until recently. The problem is with the last station #7 on the expansion module. The controller will advance to this station, start the countdown but it seems like the valve tries to open (spray heads squirts water) but that's it. It never comes on. However, I can manually advance to controller to station #7 and it will work correctly. Also, I can switch station 7 with station 6 and station 7 will come on in place of 6.

    Is the problem the controller itself or just the module will need to be replaced???

    If you are able to run the station thru the controller manually the station & module are functional. If the zone operates properly on a different station, you know the valve & circuit is functional.

    Sounds like it could be a scheduling issue if it only malfunctions.

    I would check the runtime for station #7 in all programs (A,B,C,D). If that does not resolve the issue, try resetting the controller (typically with something small on the back of the faceplate) and reprogramming.
