A hot tub should be somewhere you can switch off and relax, so it can be frustrating when something doesn't seem quite right. Whether it's not heating properly, the jets feel weaker than usual or the water doesn't look as clear as it should, most hot tub problems are fairly common and often easier to fix than you might think.
Below, we've covered some of the issues hot tub owners come across most often, along with simple checks you can do before calling in the experts.
The water isn't heating up as it should
If your hot tub isn't reaching the correct temperature, the first thing to do is check the basics. It sounds obvious but make sure the temperature hasn't been knocked down on the control panel. This can happen more often than people realise.
Next, take a look at the filters. When filters become dirty or clogged, water can't flow properly through the system, which affects how well the heater works. A quick clean or filter change can often make a noticeable difference.
If everything looks fine but the water still won't heat, there may be an issue with the heater or a temperature sensor. At that point, it's best to get it checked professionally rather than risk causing more damage.
The jets feel weak or aren't working properly
Weak jet pressure can take the enjoyment out of your soak. In many cases, this is down to something simple. Check that all the jets are fully open, as some can be adjusted or turned off individually.
Water level is another common cause. If the water is too low, the pump won't be able to push water through the jets effectively. After topping it up, you may also need to run the pumps briefly to clear any trapped air, especially if the hot tub has recently been refilled.
If the problem continues, the filters may need cleaning or replacing, as restricted water flow can reduce jet performance.
Cloudy or foamy water
When hot tub water doesn't look quite right, it's usually a sign that the water chemistry needs some attention. Cloudy water is often caused by unbalanced chemicals, infrequent filter cleaning or a build-up of everyday contaminants such as body oils and lotions.
Testing the water and adjusting the levels usually clears the problem fairly quickly. Keeping on top of regular maintenance, including cleaning the filters and changing the water when needed, helps prevent it coming back.
Foamy water is another common issue and is normally linked to residues from detergents, cosmetics or swimwear. While anti-foam products can help in the short term, good water care and encouraging bathers to rinse before using the hot tub will make a bigger difference in the long run.
The hot tub keeps tripping the electrics
If your hot tub is tripping the electrics, it's important not to ignore it. This can happen if there's a fault with a component, moisture where it shouldn't be or an issue with the heater or pump.
Resetting the breaker might get things running again briefly, but if it keeps happening, it's a sign something isn't right. For safety reasons, electrical issues should always be checked by a qualified professional.
Error messages on the control panel
Seeing an error code pop up on the display can be worrying, but these messages are designed to help rather than alarm you. They often point to specific issues such as low water flow, overheating or sensor problems.
Some error messages are easy to resolve once you know what they mean, for example by topping up the water or cleaning the filters. Others will need a closer look from a technician to make sure everything is working as it should.
When it's time to call in a professional
While many minor hot tub issues can be sorted with a few simple checks, there are times when expert help is the best option. Ongoing heating problems, electrical faults or repeated error messages shouldn't be left unresolved.
