LED lights in the spa do not work or are stuck on one color, while other functions are normal.

Safety first: Turn off power before accessing any lighting components.

• Check lighting settings: Use the topside control to cycle through lighting modes. Ensure lights are not simply turned off or in a static mode.
• Inspect connections: In the equipment bay, locate the LED driver or light harness connections on the control board and verify they are secure.
• Observe individual lights: If only one light is out, that LED assembly may be failed and require replacement.

Replacement of LED drivers or multiple light assemblies may require partial spa disassembly and is best handled by a technician familiar with Aquaterra lighting systems.
