The light and Pump cycles on your AeroGarden will differ depending on which model AeroGarden you have and, with some models, which Seed Kit you are growing.
When you plug in your AeroGarden after assembling it out of the box, the lights will come on, but the Pump may not start up immediately. (Some of our Quick Start Guides mistakenly say that when you plug in your new AeroGarden, both the Pump and Lights should come on right away. This is incorrect, and that documentation is now being updated). The very first cycle of your new AeroGarden may not be as expected because of the test cycle performed at the factory prior to packaging. It may take up to 12 hours for the Pump to begin cycling the first time you plug it in.
To determine if the Pump itself is good and is just in an "off" cycle, you can perform this quick check: push and hold the "Select" button on the base for five to six seconds. This starts the AeroGarden's selff-diagnostic during which all of its systems should come on and go off, including the Pump. If it's OK, you will hear it hum briefly and start pumping water which will gurgle for a bit before the pump stops at the end of its test.
