5.2 Cleaning the Sensor

After a water detection event, it is important to clean and dry the sensor to ensure proper future operation. Simply wipe off any water from the sensor contacts and body with a dry cloth.

6. Troubleshooting

• No Alerts Received:
  • Ensure the gateway is connected to a 2.4GHz WiFi network. 5GHz networks are not supported.
  • Check if the gateway is powered on and has sufficient battery.
  • Verify that the sensor batteries are not depleted.
  • Confirm that app notifications are enabled on your smartphone.
  • Ensure the sensor is within range of the gateway (up to 328ft).
• Sensor Not Pairing:
  • Make sure the sensor is a WD77 model, as only WD77 sensors can be paired with the WiFi gateway. Classic WD76 models are not WiFi compatible.
  • Ensure the sensor has fresh batteries.
  • Try resetting both the sensor and the gateway, then attempt pairing again.
• Inaccurate Detections:
  • Ensure the sensor contacts are clean and dry when not in use.
  • Verify the sensor is placed on a flat surface where water can reach the detection points.
