What to Do When Your Aerogarden Isn’t Detecting Water

If your Aerogarden isn’t detecting water, it could be due to a number of different issues. This can be a frustrating problem, as a lack of water can lead to serious problems with your Aerogarden, including plant death. By taking the time to identify and address the issue, you can ensure that your Aerogarden is functioning properly and that your plants are healthy and productive.

Some common causes of the Aerogarden not detecting water include a low water level, a malfunctioning water pump, a malfunctioning water level sensor, a problem with the power supply, or damage to the Aerogarden itself. You can often resolve the issue by following simple troubleshooting steps and getting your Aerogarden up and running again.

Before we discuss this further, let’s quickly check in on what an Aerogarden is.

What is an Aerogarden?

An Aerogarden is a type of hydroponic system for growing plants indoors. It consists of a container that holds a water reservoir and a growing tray, along with a light source and a water pump. 

The system allows anyone to grow plants in Grow Sponges, made from Canadian sphagnum peat, and fed a nutrient solution through an irrigation system.

To use an Aerogarden, you simply need to fill the water reservoir with water and add the recommended amount of nutrients. The Aerogarden will automatically water and feed the plants as needed. The built-in grow lights will provide the plants with the light they need to grow and thrive. 

By following the recommended care guidelines and regularly monitoring the plants, you can enjoy a steady supply of fresh, homegrown plants all year.

What to do when your Aerogarden isn’t detecting water

If your Aerogarden isn’t detecting water, it could be due to a number of different issues. Here are some steps you can take to troubleshoot and resolve the problem.

1. Check the water level

Make sure that there is enough water in the reservoir for the Aerogarden to function properly. If the water level is too low, the Aerogarden may not be able to detect the water.

2. Check the water pump

If the water pump is not functioning properly, it may be preventing the Aerogarden from detecting the water. Unplug the Aerogarden and remove the water pump to see if it is clogged or damaged. If it is clogged, you can try cleaning it out with a small brush. If it is damaged, you may need to replace it.

3. Check the water level sensor

The water level sensor is responsible for detecting the water level in the Aerogarden. If it is not functioning properly, the Aerogarden may not be able to detect the water. To check the water level sensor, you will need to remove it from the Aerogarden and test it using a multimeter. If the sensor is not functioning properly, you may need to replace it.

4. Check the power supply

If the Aerogarden is not getting power, it will not be able to detect the water. Make sure that the power cord is securely plugged into the Aerogarden. Check too that it is plugged into a working outlet.

5. Check for damage

If the Aerogarden has been dropped or damaged in some way, it may be preventing the water from being detected. Inspect the Aerogarden for any visible damage. Look for cracks or loose parts and repair or replace any damaged components as needed.

6. Perform a reset

If you have tried all of the above troubleshooting steps and the Aerogarden is still not detecting water, you may need to perform a factory reset. To reset the Aerogarden, unplug it from the power source and wait for a few minutes. After a few minutes, plug it back in and see if the issue has been resolved.

If all else fails, and you are unable to resolve the issue on your own, you may need to contact Aerogarden customer support for further assistance. They can provide additional troubleshooting steps and may be able to provide a replacement part if needed.
