We sincerely hope that your hot tub remains in perfect working order at all times. Prior to leaving the factory, every hot tub undergoes a rigorous testing process. It is filled with water, and all its pumps and heaters are activated to ensure that each component functions flawlessly.

Nevertheless, a hot tub is a mechanical device, similar to a car. With extended use, there's a likelihood that it will require some maintenance. This guide aims to assist you in diagnosing problems if you encounter any and to familiarize you with common issues if you're contemplating a hot tub purchase. Drawing on over four decades of industry experience, we're well - versed in the potential problems that can occur and, in most cases, how to prevent them.

Which Parts of a Hot Tub are Prone to Problems?

Pumps

Hot tubs typically come equipped with either one or two pumps. In a single - pump setup, the pump is responsible for powering both the jets and facilitating water circulation. In a dual - pump system, a smaller pump manages water circulation, while the larger one powers the jets. Dual - pump systems are generally regarded as more efficient because the workload is distributed, reducing the stress on each pump. Pumps perform a substantial amount of work, and the most prevalent issue is leakage. Over time, the seals that prevent water from escaping can degrade, leading to leaks.

Heater

The heater's primary function is to warm the water in the hot tub. It does this by forcing water through a heating element. If the water is not clean or its chemical balance, particularly the pH level, is off, the heater has to contend with impurities flowing through it. This can cause stress on the motor over time, potentially leading to malfunctions.

Filters

Filters play a crucial role in maintaining water quality by removing particles from the water. If filters are left unchanged or uncleaned for too long, the mechanical components of the hot tub can become clogged. Similar to the filters in your furnace, hot tub filters need to be cleaned or replaced regularly to ensure optimal performance.

Water

Maintaining proper water quality is a fundamental aspect of hot tub maintenance. As part of routine upkeep, the water must be sanitized, and its pH balance needs to be closely monitored. If the water becomes too acidic (low pH), it can corrode the hot tub's components. Conversely, if the water is too alkaline (high pH), calcium deposits can build up over time, coating the hot tub parts. Both situations are manageable, but prevention is always better than cure. Additionally, poor water maintenance can lead to issues such as green - colored water, foaminess, cloudiness, unpleasant odors, and skin irritation.

Cabinet and Frame

The stability of the hot tub's cabinet and frame is essential. If the hot tub is not placed on a level and sturdy surface, the cabinet may warp. The frame, much like those in houses, can be constructed from materials such as steel, ABS, or wood, all of which can provide reliable support when properly installed.

Electrical System

The electrical system powers the control panel, pumps, and heater of the hot tub. Malfunctions in the motherboard can occur, and error codes may appear on the keypad. These issues can disrupt the normal operation of the hot tub and require professional attention to diagnose and repair.

Hoses

Hoses are responsible for transporting water to the jets. You're likely to notice a problem with the hoses only when a leak occurs. Under normal circumstances, they require minimal maintenance.

Jets

Jets are a common component that may need replacement. If the water's chemical balance is off, calcium can accumulate in the jets, clogging them and reducing their effectiveness.

Guide to Hot Tub Reliability

Does the Type of Insulation Affect Hot Tub Repairs?

Insulation plays a critical role in both the energy efficiency and the ease of repair of a hot tub. Hot tubs with full - foam insulation are densely packed with insulation material. When repairs are needed, this insulation often has to be cut away to access the components, making the repair process messy and costly. After the repair, the insulation needs to be replaced.

Based on our experience, we've made a switch from full - foam insulation. Our current models feature a thermal blanket. This design allows for easy access to components that require repair. The thermal blanket can be simply lifted aside, reducing the complexity and cost of repairs while still providing excellent insulation and energy efficiency.

What are the Main Problems Faced by Hot Tub Owners?

1. Water - related Problems: Water - related issues top the list of common hot tub problems. These can range from short - term problems like water discoloration to long - term issues such as the calcification of mechanical parts due to prolonged pH imbalance. Most water - related problems stem from inadequate maintenance. Skipping a maintenance step or failing to address an issue promptly can lead to a cascade of problems. To keep your hot tub in good condition, the water must be clean, balanced, and continuously circulated.

2. Heater Problems: Heater problems often arise due to water chemistry issues. If the water is too acidic for an extended period, it can eat away at the rubber seals in the heater, causing leaks. High - pH water can lead to the accumulation of calcium and minerals on the heating element, reducing its efficiency. Proper filter maintenance is key to preventing heater problems. If pleated filters are not cleaned or replaced regularly, the flow of water through the heater can be restricted, leading to a "dry fire" condition. This can trigger error codes such as "low - flow error" or "dry - fire error." Another type of filter, the depth filter, which is shaped like a roll of paper towels, can disintegrate if the water chemistry is poor. Replacing a heater usually costs less than $500, and in most cases, it's more practical to replace the heater rather than attempt complex repairs.

3. Leakage Problems: Before delivery, we conduct thorough leak - testing on hot tubs. We fill the tub with water and run the pumps and heaters for several hours. If a leak occurs after delivery, it's usually due to a pipe gradually becoming loose over time or an issue that occurred during transportation. Thanks to our manufacturing design, once the leak source is identified, repairs are relatively straightforward. However, water can move within the hot tub, and the visible drip may not be at the actual leak point. In the case of full - foam insulation (which we no longer use), finding the leak source often involves cutting through a significant amount of insulation. In cold climates, frozen pipes can also cause leaks, especially if the hot tub is accidentally turned off in winter, halting water circulation.

4. Pump Failures: Pumps are complex components that work hard to keep the water circulating and the jets functioning. Most pump problems are related to usage and wear - and - tear. Over time, the constant operation of the pump can lead to mechanical wear. If the water is not properly balanced, the pump has to work harder to overcome the effects of calcium buildup or acidic water. While some pump issues can be repaired, in many cases, replacement may be necessary, and this can cost up to $1000 or more.

5. Circuit Breaker Tripping: Although not a common issue, circuit breaker tripping usually indicates a problem with the heater. However, it could also be caused by a malfunction in any part of the hot tub's electrical system.

6. Error Code Problems: Error codes on the hot tub's control panel are relatively rare but can occur. If moisture infiltrates the control panel, it can cause electrical malfunctions. Resolving these issues typically involves replacing the short - circuited components and identifying the source of the moisture.

7. Cover Problems: The cover of the hot tub serves an important function in retaining heat when the tub is not in use. However, it's also exposed to the elements, especially sunlight. Depending on your location and the amount of sun exposure, the cover may need to be replaced every three to five years.

8. Chipped or Stained Acrylic Problems: Minor chips in the acrylic surface of the hot tub can usually be repaired using filler. However, in certain lighting conditions, the repair seam may still be visible. Stains on the acrylic can almost always be removed or minimized using appropriate cleaning products, which are usually available from your dealer. Acrylic is a durable material, but it still requires proper care.

Note: For all repairs, it's advisable to consult a professional service provider or your dealer before attempting any DIY fixes. Repair costs can vary, but on average, they are around $150 per hour, depending on your location.

What Questions Should You Ask Before Buying a Hot Tub?

How to Keep Your Hot Tub in Optimal Operating Condition: Our Top Hot Tub Maintenance Tips

Learn the Basics: Before your hot tub is delivered or as soon as it arrives, make sure you receive a comprehensive orientation on its operation and maintenance. Many reputable retailers offer what's known as "spa school" - a service where an expert comes to your home to teach you how to use and care for your hot tub.
