# Irrigation Issues

If the app shows that your device is irrigating but no water flows—or if water continues even after irrigation should stop—follow the steps below to identify the cause.

## 1. “No Water Flow” Issue

If the device shows a green LED Wink (connected) but no water is flowing:

**Run a Test**
 Start an Irrigate Now test from the app.
 Does the blue irrigation icon appear, and does the device show a blue LED Wink?

**Check the Solenoid Coil**
 If the blue LED Wink is active, the device is sending commands.
 Listen for a small “click” or feel a slight vibration on the solenoid coil.

**Check the Water Source**
 Make sure the main water valve is open and that any pump system (if present) is running.

**Check the Wiring**
 Test a different zone.
 If all other zones work except one, that valve may have a loose or broken wire connection.

## 2. “Water Does Not Stop” Issue (Important!)

If water continues flowing even after irrigation should end, determine whether the issue is electrical or mechanical:

**Disconnect Power**
 Unplug the device completely.
 (For battery models, remove and reinsert the batteries—or replace them if needed.)

**Result A – Water Stops**
 If water stops when power is removed, the issue may be related to the device relay or software.
 Please contact our technical team.

**Result B – Water Continues**
 If water keeps running even with no power, the issue is almost certainly mechanical.
 Dirt, sand, gravel, or algae may be stuck inside the valve, preventing the diaphragm from fully closing.

**Immediate Action**
 Close the main water valve to prevent flooding.

**Solution**
 The valve may need cleaning or the diaphragm may require replacement.
 We recommend assistance from a professional plumber or gardener.
