If you feel comfortable troubleshooting the heater, try removing it and inspecting for any signs of burning.

Is your hot tub still not heating up? It could be a faulty heating element. Fortunately, dealing with this issue isn’t too difficult to resolve. This is when air gets stuck and blocks the flow of water, preventing it from heating properly. If you’ve recently filled up your hot tub, there’s a chance that an airlock has formed in the plumbing lines. If the high limit switch was triggered due to excessively hot water or air trapped in your lines, resetting should get it running again. Next, flip your heater breaker or press the reset button. Even though these options might seem mundane, they are also the most efficient and cost-effective so make sure to try them first before attempting anything else. Additionally, it is a good idea to clean or replace the filter. Start by examining the water level and then search for obstructions in your circulation system. No matter what, you still don’t have any heat. Utilizing a multimeter can help pinpoint the source of the problem by testing electrical components quickly and accurately. To narrow down what could be causing this issue, determine if the water stays cold or begins to warm up before cooling off again. A hot tub without hot water is essentially just a regular bathtub. If you’re ready to relax in your spa only to find the water is frigid, it can be immensely frustrating. Several common hot tub issues have simple solutions you can handle on your own. Before you panic about what it’ll cost to get a repairman to fix your spa on the weekend, try a little DIY hot tub troubleshooting first. Whatever the problem, your night is not working out the way you’d hoped. Or maybe your pump kicks on and produces an ear-splitting screech. Or maybe when you turn on your hot tub, the breaker trips. Or maybe your water is fine, but when you turn on your jets, nothing happens. You remove your hot tub cover, only to find the water is ice cold. You’re ready to sit back and relax in your bubbling, steamy hot tub.
