Troubleshooting Spa Lighting Issues

If your spa lights aren’t turning on, are dim, or behaving unexpectedly, this guide walks you through the most common causes and how to resolve them.

Overview

Lighting issues are typically caused by settings, wiring, or component wear—not major system failures.

 

Quick Check

  • Make sure lights are turned on at the control pad
  • Cycle through lighting modes
  • Check for power to the spa

 

Step-by-Step Troubleshooting

Step 1: Check the Lighting Mode

Lights may be in:

  • Off mode
  • Dim setting
  • Color cycle mode

Cycle the light button several times.

Step 2: Power Reset

  • Turn breaker OFF
  • Wait 30 seconds
  • Turn back ON

Step 3: Check for Error Messages

Look at the control panel for alerts that may disable accessories.

Step 4: Inspect for Partial Lighting

  • Some lights working = possible bulb/LED issue
  • No lights working = likely control or wiring issue

Step 5: Check Connections (if accessible)

Loose connections can affect lighting performance.

 

Common Causes

  • Settings or mode confusion
  • Failed LED/light assembly
  • Loose wiring
  • Control system issue

 

When to Contact a Dealer

  • Lights remain off after reset
  • Multiple zones not working
  • Visible damage or water intrusion
