Not only is it inconvenient and a nuisance to troubleshoot, repairing it can be an unexpected expense and replacing it can be even more costly. No one likes a hot tub control panel that’s not working properly. Enter “Priming Mode” on your control panel and test the buttons.Ensure the voltages between the control panel and the system pack terminal block are compatible.The connection could be compromised in some way (loose, bent, damaged) and needs to be fixed/replaced. Inspect the connection between the board and the control panel.If they need to be repositioned, turn off the power to the tub before resetting them. Start by verifying the DIP switches on the board are in the factory default positions.This could be the result of a damaged panel, insufficient voltage, or a faulty connection between the control panel and the circuit board. Unresponsive buttons are an issue you may encounter with your controls. These lines can “cross” if they’re too close to each other, causing the display to act erratically. You can test it using a multimeter, but if voltage isn’t your specialty you may want to call a professional to fix it.Īdditionally, you may have an issue with the cable from the control panel being too close to another cable in the filtration system. If The Display Flickers On And OffĪ flickering display is a sign that the voltage from the transformer is too low. In this case, a full panel replacement is usually the best solution.Ī wrong display can also be a sign that the control panel has run its course, and again, will require replacement. This borders on error messages (see above), however, it also may be presenting the right information, but with compromised LEDs that make it look incorrect.Īn issue like this could be the result of a cracked panel, or one that has been exposed to moisture. Sometimes, a display will begin showing the wrong information. Most error messages can be fixed, but you might need to get a new one depending on the age of the controller. If the display shows an error message, you should consult the hot tub’s owner’s manual to cross reference the message you’re seeing.Ī display error that’s blinking or flashing may only need something as simple as a system reset, whereas any kind of truncated display can indicate there is moisture or dirty contacts inside the controller. If none of these work, you may have to fully replace the topside controller, as they do have a shelf life of around 10 years.Any compromised areas could cause the display to fail. Look over the circuit board for any damage on it.Double check that the topside controller is compatible with the circuit board model.Ensure power is present at the fuse and that it isn’t blown.Check the circuit board transformer to make sure there is power.You may have a situation where the termination point has failed for one reason or another and needs a new end on it. Ensure all cables are connected cleanly as well. They may have come loose, or been damaged in some way (rodents like to gnaw wires). Inspect the cables that run to the controller.Check the controller for any condensation that may be present between the overlay and the display.Turn off the power, wait for 20 seconds, and turn it back on. Sometimes this universal “trick” can fix any electronics issue. Start by resetting the spa controller.If the display isn’t showing anything, you’ve got a problem.įollow these steps to get it operational again” Issues with topside and spa side control panels are varied, so we’ve compiled a list of the most common problems and what you can do to rectify the issues. How To Fix A Hot Tub Control Panel (Troubleshooting) With recent advances in technology, wireless remotes are also available, although they are usually only compatible with certain controllers. In most cases, the remote will be installed at the tub, and hardwired back to the control panel through tubing. Many spa side controls will be linked up with a remote, so you can still access the control system while in the tub. This is known as a spa side control panel. If you have a tub that was built from the ground up, the controls will be housed with the rest of the spa equipment. The buttons control the functions and the screen communicates to the user what current function is being carried out.īoth digital and analog panels exist, and they’re designed to work only with specific control boards. It consists of a small screen outfitted with LEDs or LCDs, with various buttons and indicators covered in an overlay. This is known as a topside control panel. It handles everything from the main power, to the spa jets, and even things like the lights and music.Ī standalone hot tub has the control panel built into the top of the tub. The hot tub control panel is a functional display system that operates all your tub’s features. How To Fix A Hot Tub Control Panel (Troubleshooting).
