What was recalled
If you own a high-end hot tub from either the Jacuzzi or Sundance Spas brands, it is important to know exactly which units are affected by this significant safety recall. Issued by the U.S. Consumer Product Safety Commission (CPSC) on December 15, 2022, this notice targets specific collections of spas that were manufactured with a defective temperature sensor. The recall does not apply to every hot tub produced by these companies, but it is quite broad within its scope, covering two distinct lines of products that share a common component flaw.
First, the recall affects Jacuzzi brand hot tubs belonging to the J-200, J-300, J-400, and J-500 collections. These are popular models known for their durability and hydrotherapy features, but they contain a sensor that can misreport the water's actual heat level. Second, the recall extends to Sundance Spas brand units from the 680, 780, 880, and 980 Series spas. While these are separate brands under the same parent company, they are included in this notice because they utilize the same faulty sensor technology that poses a risk of thermal burns and heat stroke.
It is crucial to understand that you cannot identify a recalled unit simply by looking at the exterior shell or the brand name alone. The specific model matters immensely. To determine if your spa is included, you must locate the equipment bay on your hot tub. Inside this compartment, there will be a silver plate where both the model number and serial number are engraved. This is your primary key to verification. You can enter these numbers into the official recall lookup tools available on www.sundancespas.com/en-us/recall.html or www.jacuzzi.com/en-us/recall.html to confirm if your specific unit’s sensor is part of the defective batch.
The recall was prompted by a substantial number of reports indicating that the temperature sensor can relay incorrect water temperatures, causing the water to become hotter than the user has set on the control panel. Sundance Spas has received 185 reports of these inaccurate temperature readings. While no injuries have been reported to date, the potential for serious harm is real, which is why the company and the CPSC are taking this proactive step. The company is also contacting all known purchasers directly to ensure they are aware of the issue, but it remains your responsibility to verify your unit’s status using the serial number provided on the silver plate in the equipment bay.
The hazard, explained
At the heart of this recall is a subtle but potentially dangerous malfunction within the hot tub’s control system: specifically, the temperature sensor. To understand why this matters, it helps to look at how these spas are designed to work in the first place. Hot tubs rely on sophisticated electronic sensors to monitor water heat levels and communicate that data to the user via the control panel. When you set your spa to 102 degrees, for example, the sensor tells the heater to stop working once that target is reached, maintaining a comfortable and safe soak.
In the recalled units, this communication link breaks down. The faulty sensor can relay incorrect information to the display, showing a water temperature that is significantly lower than what the water is actually at. Imagine setting your spa to 102 degrees, seeing "102" on the screen, and stepping in, only to find the water is nearly 115 degrees or hotter. This discrepancy creates a silent trap. Because the user trusts the digital readout, they may stay in the water longer than their body can safely handle, unaware that the heat is accumulating beyond safe limits.
This leads directly to two primary health risks: thermal burns and heat stroke. Thermal burns occur when skin is exposed to excessive heat for a prolonged period. Even if the water doesn't feel "scalding" instantly due to the numbing effect of hot water and massage jets, the underlying tissue can sustain damage that manifests later as redness, blistering, or deeper injury. Heat stroke is a more serious, systemic condition where the body’s internal cooling system fails because it cannot dissipate heat fast enough into blood vessels near the skin. When the water is hotter than indicated, your core body temperature rises rapidly, potentially leading to confusion, loss of consciousness, organ failure, or in rare cases, death.
The urgency of this hazard is underscored by the volume of reports received. Sundance Spas has documented 185 instances where customers noticed these inaccurate temperature readings. While it is reassuring that no injuries have been officially reported to date, the potential for harm is real and immediate for anyone using a unit with the defective sensor. The danger is particularly insidious because it relies on trust in the machine’s display—a trust that, in this case, is misplaced. Until the sensor is repaired, the only reliable way to know your actual water temperature is to bypass the electronic readout entirely and use a trusted, external physical thermometer.
Who is most at risk
When a hot tub’s temperature sensor fails and allows the water to become hotter than the set limit, the danger extends beyond simple discomfort. While any user can suffer from heat-related illness, certain groups are significantly more vulnerable to severe injury or even life-threatening thermal burns. Understanding who is most at risk helps explain why the Consumer Product Safety Commission (CPSC) and Sundance Spas emphasize immediate action for all owners, regardless of age or health status.
The primary group at elevated risk includes young children. Children’s bodies are not as efficient at regulating temperature as those of adults. Their smaller body mass means that their core temperature rises much faster when exposed to hot water. A setting that an adult might find merely "warm" or "pleasantly heated" can cause a child’s internal temperature to spike dangerously in a matter of minutes. This rapid rise can lead to hyperthermia, where the body overheats because it cannot release heat fast enough to counteract the external heat source. For children, the margin for error is slim; what might be a mild discomfort for an adult can result in confusion, lethargy, or loss of consciousness for a child, increasing the risk of drowning if they become incapacitated in the water.
Elderly individuals and those with pre-existing health conditions also face heightened dangers. Hot water causes blood vessels to dilate, which lowers blood pressure. For older adults or people managing heart conditions, hypertension, or diabetes, this sudden drop in blood pressure can lead to dizziness, fainting, or cardiac stress. If a person loses consciousness in a hot tub, the combination of heat exhaustion and potential drowning creates a fatal dual hazard. Furthermore, individuals with neuropathy or reduced sensation—often due to diabetes or other neurological conditions—may not feel the water becoming dangerously hot. Their bodies might send pain signals that are delayed or muted, allowing them to remain in scalding water longer than they should, leading to severe thermal burns that can damage deep tissue layers without immediate awareness.
Additionally, pregnant women are advised to avoid hot tubs altogether, but this recall makes the risk even more acute. Elevated core body temperature during pregnancy, particularly in the first trimester, has been linked to neural tube defects and other developmental issues. The hazard here is not just the burn, but the physiological stress placed on both the mother and the developing fetus by excessive heat exposure.
Finally, anyone using the hot tub for extended periods of relaxation or hydrotherapy is at greater risk. The longer you stay in water that is hotter than intended, the deeper the heat penetrates your tissues. This can lead to "erythema ab igne," a condition where prolonged heat exposure causes skin damage and discoloration, as well as systemic heat stroke symptoms like nausea, headache, and rapid pulse. Because the recalled Jacuzzi and Sundance Spas models may display incorrect temperatures, users relying on the tub’s built-in thermometer may unknowingly stay in hazardous conditions for too long. This is why using an external, accurate thermometer is not just a precaution—it is a critical safety step for every single user, regardless of their demographic profile.
How to tell if you have the recalled item
Before taking any further action, it is essential to confirm whether your specific hot tub or spa unit is part of this recall. Because the issue involves a hidden internal component—the temperature sensor—you cannot identify the problem simply by looking at the exterior finish, color, or size of the unit. The affected products span two major brands, Jacuzzi and Sundance Spas, and include several distinct model collections. Therefore, your first step is to locate the official identification plate attached to your equipment.
You will find a silver nameplate engraved with critical details inside the equipment bay of the hot tub. This compartment typically houses the pump, heater, and control systems, so you may need to remove a section of the spa’s sidewall or access panel to see it clearly. Once you have located this plate, look for two specific pieces of information: the model number and the serial number. These alphanumeric codes are your only reliable way to verify if your unit is included in the recall.
The recall specifically targets Jacuzzi J-200, J-300, J-400, and J-500 collection hot tubs, as well as Sundance Spas 680, 780, 880, and 980 Series spas. If your model number falls within these ranges, you should not rely on guesswork. Instead, take the serial number from the silver plate and enter it into the official recall lookup tools. For Jacuzzi brand units, visit www.jacuzzi.com/en-us/recall.html. For Sundance Spas brands, go to www.sundancespas.com/en-us/recall.html. These online portals are designed to cross-reference your unique serial number against the list of affected sensors, providing a definitive answer on whether your specific unit requires repair.
If you cannot locate the silver plate or if the engraving is worn and illegible, do not attempt to open the equipment bay yourself if it voids your warranty or requires specialized tools. In this case, contact the manufacturer directly for assistance. Sundance Spas can be reached at 800-549-1502 from 7 a.m. to 4 p.m. PT, Monday through Friday. For electronic support, you may email TempSensor@jacuzzi.com for Jacuzzi brands or TempSensor@sundancespas.com for Sundance Spas brands. They can help you identify your model and verify the recall status using other available records.
It is important to note that this recall does not depend on when or where you purchased the unit, nor does it matter what color your spa was finished in. The hazard is strictly tied to the manufacturing date and the specific sensor batch installed in the listed models. Even if your hot tub looks brand new or has been in use for many years, the only way to be certain of its safety status is through the serial number verification process mentioned above. Until you have confirmed your unit is not affected, please adhere to the safety precautions outlined in our next section.
What to do — step by step
If you own one of the recalled Jacuzzi or Sundance Spas hot tubs, the most important thing right now is to prioritize your safety while you arrange for the necessary repairs. The recall notice from the Consumer Product Safety Commission (CPSC) outlines a clear, two-part process: immediate temporary precautions and long-term resolution. Please follow these steps carefully to ensure you do not suffer injury or thermal burns. First, if you have not already done so, verify whether your specific unit is included in this recall. You can find the model number and serial number engraved on a silver plate located in the equipment bay of your hot tub. Enter this serial number into the official recall lookup tools available at www.sundancespas.com/en-us/recall.html or www.jacuzzi.com/en-us/recall.html. This step is crucial because it confirms whether your sensor is part of the defective batch. If your unit is not listed, you do not need to take further action regarding this specific recall, though regular maintenance is always recommended for any spa owner. If your serial number matches a recalled unit, you must take immediate cautionary measures before using the hot tub again. The core hazard here is that the internal temperature sensor may relay incorrect readings, potentially allowing the water to become dangerously hotter than the set temperature. To protect yourself from heat stroke or thermal burns, you should use an accurate external thermometer to check the water temperature every time you plan to enter the spa. Do not rely on the hot tub’s built-in display. Confirm that the water is no higher than 104 degrees Fahrenheit before entering. If your external thermometer reads any temperature above 104 degrees, do not enter the hot tub under any circumstances until the issue is resolved. This temporary step is vital because it bridges the gap between discovering the defect and having it professionally repaired. Next, you need to schedule a free repair for your unit.

What can happen if you ignore it
It is completely understandable why you might hesitate to stop using your hot tub immediately. These are significant investments in home comfort and relaxation, and the idea of sitting in cold water or waiting for a repair technician can feel like an inconvenience rather than a necessary safety precaution. However, ignoring this recall is not merely a matter of missing out on a free service; it is a decision that directly impacts your physical safety. The core issue with these specific Jacuzzi and Sundance Spas models is not a mechanical failure that will break the tub, but a silent sensor error that tricks you into believing the water is safe when it is actually dangerous. When you continue to use a hot tub with this faulty temperature sensor, you are relying on a false sense of security. The control panel may display a comfortable 102 degrees, but the actual water temperature could be significantly higher. Because your body relies on that displayed number to gauge its own limits, you are likely to stay in the water longer than is safe. This is where the real danger lies. Prolonged exposure to water that is hotter than the set temperature can lead to hyperthermia, a condition where the body absorbs heat faster than it can dissipate it. In severe cases, this can result in heat stroke, a life-threatening emergency where the body’s temperature regulation system fails. The consequences of thermal burns are equally serious and often more immediate. Water that is just a few degrees above the safe limit of 104 degrees can cause first-degree burns (redness and pain) or even second-degree burns (blistering) after relatively short exposure times, especially for children or individuals with sensitive skin. While the recall notice notes that Sundance Spas has received 185 reports of inaccurate temperature readings and no injuries have been reported to date, this lack of reported injury data should not be misinterpreted as proof that the risk is low. Heat-related injuries can sometimes manifest slowly, or victims may attribute their symptoms to other causes until it is too late. The absence of reported injuries so far is a statistical snapshot, not a guarantee of safety for every individual user. Furthermore, ignoring the recall means you are depriving yourself of the opportunity to have this critical flaw fixed at no cost. By waiting, you are essentially gambling with your health and that of your family members who might use the spa. If you do experience an injury, the emotional and financial toll will far outweigh the brief inconvenience of scheduling a repair. The sensor issue is a known defect that the manufacturer has acknowledged and is actively correcting. Choosing to do nothing leaves you vulnerable to a preventable hazard that could result in hospitalization, permanent skin damage, or worse. The path forward is clear: verify your model, stop using the tub if there is any doubt, and take advantage of the free repair before the sensor causes real harm.Staying safe: broader tips
While this specific recall addresses a known defect in certain Jacuzzi and Sundance Spas models, maintaining long-term safety with any hot tub or spa requires a proactive approach to both equipment maintenance and personal habits. The primary danger of thermal burns and heat-related injuries is often rooted in the assumption that built-in sensors are infallible. As this incident illustrates, electronic components can fail or drift out of calibration over time. Therefore, relying solely on the control panel’s digital readout for safety is a risk no one should take. Instead, treat your hot tub’s internal thermometer as a suggestion rather than a fact. Keeping a reliable, waterproof external thermometer in the water at all times is one of the most effective habits you can develop. This simple tool provides an independent verification of the water temperature, ensuring that it never exceeds the safe maximum of 104 degrees Fahrenheit (40 degrees Celsius), which is critical for preventing hyperthermia and severe burns, especially for vulnerable users.
Equally important is understanding who is most susceptible to these hazards. Older adults, young children, pregnant individuals, and those with certain medical conditions or medications that affect heat tolerance are at significantly higher risk. It is wise to establish clear family rules before entering the spa. For instance, limit soak times to 10-15 minutes regardless of how comfortable the water feels, and always enter slowly to allow your body to adjust to the temperature. Hydration is also key; because hot tubs accelerate dehydration, drinking water before and after use helps regulate your body’s core temperature and reduces the strain on your cardiovascular system.
Beyond immediate usage habits, regular professional maintenance plays a crucial role in preventing unexpected failures. Schedule annual inspections with authorized dealers to check electrical connections, sensor accuracy, and heating elements. This proactive care not only extends the life of your equipment but also catches potential issues before they become safety hazards. Additionally, make it a habit to register your new appliances and sign up for recall alerts from manufacturers and government agencies like the CPSC. Many recalls are issued long after purchase, and being part of a notification system ensures you are informed if a defect is discovered in your specific model years later. By combining general vigilance with specific checks, you can enjoy the relaxation benefits of your hot tub without compromising your safety.
