If you're either considering buying a hot tub or already own one, you know that it's similar to owning a vehicle or a household appliance. It has moving and working components, so inevitably, parts may break down and need repairs.
People often wonder, "What are the typical problems for hot tubs?" Understanding the components of a hot tub, potential issues, and repair methods is crucial for owners, as hot tubs represent a significant investment.
In this article, we'll cover:
· The hot tub parts most prone to problems.
· The main areas where issues occur.
· Our top tips for minimizing hot tub problems.
What are the Parts of a Hot Tub That Can Have Problems?
· Pumps: Hot tubs usually come with one or two pumps. In a single - pump system, the pump powers both the jets and water circulation. In a two - pump setup, a smaller pump handles circulation, while the other powers the jets. Two - pump systems are generally more reliable as the pumps have less workload. Pumps do a lot of work, and their most common problem is leakage, as seals can deteriorate over time.
· Heater: The heater warms the water by forcing it through an element. If the water is dirty or its chemical balance is off, the heater has to deal with particles passing through, which can stress the motor over time.
· Filters: Filters remove particles from the water. If you neglect filter maintenance, mechanical parts can become clogged. Similar to furnace filters, hot tub filters need regular cleaning or replacement.
· Water: As part of regular maintenance, hot tub water needs to be sanitized, and its pH balance must be monitored. If the water is too acidic (low pH), it can corrode the hot tub's parts. If it's too alkaline (high pH), calcium deposits can build up on the parts over time. Both issues are fixable, but it's best to avoid them. Poorly maintained water can also turn green, become foamy, cloudy, smelly, and cause skin irritation.
· Shell: Acrylic hot tub shells can chip, get scratched, lose their shine, or become stained if there are water quality issues. Other types of shells may also be vulnerable to scratches. Calcium buildup can stain or damage any type of shell.
· Cabinet and frame: If the hot tub is not placed on a solid, flat surface, the cabinet may warp. Frames can be made of various materials like steel, ABS, or wood, all of which can work well if properly maintained.
· Electrical: The electrical system powers the control panel, pumps, and heater. Motherboards can malfunction, and keypads may display error codes.
· Hoses: Hoses transport water to the jets. You'll usually notice a problem if a hose develops a leak; otherwise, they require little maintenance.
· Jets: Replacement jets are a common purchase because they can get blocked with calcium if the water chemistry is unbalanced.
Does the Type of Insulation Matter When It Comes to Hot Tub Repair?
Yes, it does. The insulation of a hot tub is a crucial factor in repair. Some hot tubs are insulated with full foam, which makes accessing parts difficult as the foam has to be cut out. This makes repairs messy and may require additional insulation after the repair. Other types of insulation, like a thermal blanket, can be easily removed, allowing for convenient access to parts that need repair without adding excessive costs.
What are the Top Problems Hot Tub Owners Face?
1. Water Issues: Water - related problems are by far the most common in hot tub repair. These can range from short - term issues like water discoloration to long - term problems such as calcified mechanical parts due to a pH imbalance over an extended period. Water issues are typically caused by maintenance oversights, and if left untreated, they can lead to many other problems. Maintaining proper water balance, cleanliness, and circulation is essential for a well - functioning hot tub.
2. Heater Problems: The two main heater issues are caused by water that's been too acidic for too long, which can corrode the rubber parts that keep water out, and high - pH water, which can cause calcium and mineral buildup on the heating element. Proper filter maintenance is key; if pleated filters aren't cleaned or replaced regularly, the water flow through the heater is restricted, potentially causing a "dry fire" and resulting in a "low flow error" or "dry fire error." Another type of filter, the depth filter, can disintegrate if the water chemistry is poor.
3. Leaks: Hot tubs are usually tested for leaks before delivery. However, leaks can occur after delivery due to tubes becoming loose over time or issues during shipping. In cold climates, leaks can also happen if pipes freeze, for example, if the hot tub is accidentally shut off in winter and circulation stops. Once the leak source is located, it can often be fixed relatively easily.
4. Pump Failures: Pumps are complex and work hard. Most pump problems are related to usage. Over time, pumps experience wear and tear, and they have to work harder in unbalanced water conditions. While some pump issues can be repaired, if replacement is necessary, it can cost up to $1,000 or more.
5. Tripping the Breaker: Although not extremely common, a tripped breaker is usually a sign of a problem, often related to the heater, but it could be caused by any component of the hot tub.
6. Error Codes: Error codes can appear on the control panel, usually due to moisture getting into the electrical system. Resolving this issue involves replacing short - circuited components and finding the source of the moisture.
7. Cover: The cover plays an important role in insulating the hot tub when not in use. However, it's also exposed to the sun, and depending on your location and the hot tub's placement, it may need to be replaced every three to five years.
8. Chipped or Stained Acrylic: Chipped acrylic can often be repaired with filler, although the repair seam may be visible in certain lighting. Stains can usually be removed or repaired using appropriate cleaning products.
Note: For all repairs, it's advisable to consult a professional service provider or dealer before attempting DIY repairs. Repair costs typically range around $150 per hour, but this can vary by location.
How to Keep Your Hot Tub Working at Its Best: Top Maintenance Tips
1. Educate Yourself: Before or when your hot tub is delivered, learn about its operation and maintenance. Some retailers offer training sessions where someone can show you how to use and maintain your hot tub. Familiarizing yourself with the maintenance requirements early on is beneficial for both you and your hot tub.
2. Ventilation: If your hot tub has vents, open them in the summer to reduce the load on the heater and pumps. In summer, excessive heat can build up, and using the vents can help relieve stress on the system.
3. Water Maintenance: Keep the water balanced. Check the pH balance weekly using testing strips and adjust as needed. Address water issues promptly. Turning off the air controls when leaving the hot tub and rinsing the filter every two weeks can prevent many water - related problems.
4. Filter Cleaning: Regularly clean your filters, just like you would your furnace filters. Cleaning should be a thorough process using a degreasing and cleaning solution, not just a simple rinse.
5. Seek Professional Support: Buying from a local dealer can be advantageous. Having a reliable dealer to consult for advice, especially in the first year of ownership, is helpful. Some dealers offer annual inspections, which you should consider taking advantage of.
Conclusion
We hope this article hasn't discouraged you from owning a hot tub. Like cars, hot tubs need maintenance and occasional servicing, but most require less than one service call per year. By understanding the parts, common issues, and maintenance tips, you can ensure your hot tub lasts a long time with minimal problems.
