Irrigation/Rain Dial RD-600 Flashing


Hi Jim,

I have a Rain Dial RD-600 which I have not used in about a year.
upon resetting everything and putting in the necessary inputs I have not been able to use on time, semi-automatic or on manual.

Every time I go to a specific station or set it to semi-auto the station timer keeps resetting to off and flashes or/and the time flashes really quickly and the starts to flash intermittently.

whilst flashing the station number is also flashing above the time and or it flashes A:10min when trying it manual mode!

Could you please advise.
Your help is much appreciated.

Hey Dustin, first thing to try would be to take out the battery, and then disconnect the power supply for about 1 minute. And then with the battery still out, turn the power back on. If you are still having issues, then the panel needs to be replaced. If the controller seems to work okay, but when you try to turn a station on, the display starts flashing. Then you have a problem with either the wiring, or the solenoid is shorting out the controller. If this is the case, you need to find either the bad wire(s) or the bad solenoid(s) and replace them. Good luck and have a great day.
