Troubleshooting Hot Tub LED Lights: A Step-by-Step Guide

Quck answer

Hot tub LED lights can sometimes experience issues, but troubleshooting them can be relatively simple. Here are some steps to troubleshoot hot tub LED lights:

1. Check the power supply: Ensure that the power source is connected properly and providing electricity to the LED lights. If there is a power outage or a tripped circuit breaker, reset it.

2. Inspect the LED bulbs: Examine the LED bulbs for any signs of damage or loose connections. Replace any faulty bulbs.

3. Check the control panel: Make sure that the LED lights are properly programmed and turned on in the control panel settings.

4. Test the transformer: Use a multimeter to check the transformer’s voltage output. If it’s not delivering the correct voltage, consider replacing it.

5. Consult the manufacturer’s manual: If the above steps don’t resolve the issue, refer to the hot tub’s user manual or contact the manufacturer for further assistance.

By following these troubleshooting steps, you can identify and potentially resolve any issues with your hot tub LED lights.


When it comes to enhancing your hot tub experience, LED lights can make a significant difference. They provide warmth and can change colors, promoting mental well-being along with muscle relaxation. However, if you encounter any issues with your hot tub LED lights, troubleshooting can be a simple process that doesn’t add unnecessary stress. In this guide, we will walk you through the steps to troubleshoot and get your LED lights back up and running, ensuring you can enjoy a physically and mentally rejuvenating soak in your hot tub.

Step 1: Removing the Skirting

Before diving into the troubleshooting process, it is important to access the vital connections for the LED lights. This involves removing the skirting that hides and protects the controls and electrical connections. Follow these steps:

  1. Locate the screws that secure the skirting. These screws are typically Phillips or square drive and can be found on the same side as the hot tub controls.
  2. Starting from the outer edges or corners of the hot tub, remove the screws, gradually moving towards the center of the panel. It may be helpful to have an assistant to support the panel and prevent it from dropping.
  3. Place the skirt panel on a flat surface with the outer side facing up to prevent scratches.
  4. Remove or carefully move any insulation that may obstruct access to the hot tub controls. Pay attention to how the insulation is installed to ensure proper reassembly after troubleshooting.
  5. Consult your owner’s manual for any troubleshooting information that may assist you.
  6. Once you have successfully troubleshooted the hot tub lights, reattach the skirting following the reverse order of removal.

Step 2: Checking the LED Light Connections

If you have followed the previous steps and still haven’t resolved the issue with your LED lights, it’s time to inspect the wiring connections. To do this:

1. Turn off the power to the hot tub.

2. Examine the control panel for any loose connections. These will typically be plug-in-style connections.

  1. Apply gentle pressure to the connections on the rear side of the control boards. Some of these connections may have become loose.
  2. You can also fix the connection by unplugging and plugging it back in. Do not exert force when joining the connections. They should fit together easily. Some connections have alignment features in the plug to ensure proper connection.
  3. Restore power to the hot tub and check for positive results.

If Some LED Lights Are Not Lit

In certain cases, not all LED lights in the hot tub will be lit. This may be due to a loose connection at the light itself or the light coming out of the LED light holder. Gain access to the specific light by removing any skirting and examining the connections. Check if the LED light has simply fallen out of its supporting holder and reinsert it.

When to Seek Assistance from a Hot Tub Technician

Issues like blown fuses, stuck relays, defective switches, or problems with the transformer will require a call to a local hot tub technician. Blown fuses can be replaced with fuses of the same size, but this could indicate a more serious problem. Circuit breakers can be reset, but once again, this might indicate a more serious problem. Transformers lower the voltage according to safety standards and should be replaced by a hot tub technician. Sometimes, it is best to reduce your stress and seek help from a professional.
