Rain Bird ESP‑6: Off Position Doesn’t Stop Watering – Only % Setting at Zero Works

The controller waters even when the dial is set to “Off”; only setting the seasonal‑adjust percentage to zero stops it.

Diagnosis

The microprocessor is likely glitched. Try a full reset:

  1. Remove the backup battery.
  2. Unplug the controller for 30 seconds.
  3. Replug and test.

If the problem persists, the ESP‑6 is discontinued and parts are unavailable; replacement is recommended.
