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???

Thanks,

Make sure that station 7 isn't set for one minute only.

Sorry, had problems logging in earlier.
Thanks for the reply ... Station 7 was set for 10 minutes. It acts like it wants to come on (meaning you can hear air/water squirt for about a second) but nothing after that. I can manually advance it to station 7 and it works just fine. Don't know if I should change the controller or the module itself.

Thanks mrfixit ... Tried all three to no avail. Reset, cleared memory and moved the module to a different slot. Station 7 still will not come on during the Auto Cycles but I can manually advance to it.

I think you are correct, probably the module is bad and will need to be replaced. I will start there first since they are only about $26.
