## Common issues & fixes

Step-by-step diagnostic procedures for the most frequently reported LF-One issues.

### Plug not working / Power supply turning off

Usually caused by the water pump tripping the power supply

1. **Unplug the unit** Completely disconnect from the wall outlet.
2. **Unplug the pump** Disconnect from the internal connector.
3. **Plug the unit back in** Keep the pump disconnected for this step.
4. **Check if the PLC runs correctly** If the controller powers on and operates normally, the pump is likely the issue.
5. **Plug the pump back in and observe** If the power supply trips again, the pump needs to be replaced. See the [Water Pump](https://ageyetech.com/lf-one#lf-parts) replacement part above.

### Lights not turning on or flickering

Check connections and LED driver status

1. **Check the LED connector** Ensure the light bar cable is fully seated in the connector port.
2. **Inspect the LED driver** Look for any visible damage or burn marks on the driver unit.
3. **Swap with a known working light bar** If the replacement works, the original light bar needs replacing.

### Water not draining properly

Blockage in drain line or improper tray leveling

1. **Check tray alignment** Ensure grow trays are level and properly seated on the rack.
2. **Inspect drain holes** Clear any root material or debris blocking the drain openings.
3. **Flush the drain line** Run clean water through the line to clear any buildup. Replace the [Watering Line](https://ageyetech.com/lf-one#lf-parts) if blockage persists.
