Hot tubs are an excellent way to unwind and relax after a long day, but they can also be a recipe for frustration when something goes wrong. The top three most common hot tub problems are leaks, equipment failure, and water chemistry issues. These issues can range from minor to major, with the average repair cost ranging from $150 to $500.
However, many can be resolved quickly with proper maintenance, the correct above-ground pool parts, and quick action.
Understanding and being aware of the most common hot tub problems can help you identify and address them before they become more significant issues and ensure that your hot tub stays in good working condition for years to come.
To help you troubleshoot and fix common hot tub issues, we’ve compiled a list of the five most common problems and what pool repair services you may need to address them.
1. Water Leaks
Water leaks are one of the most common hot tub problems. Various issues, including worn or damaged seals, cracks in the hot tub structure, or leaks in the plumbing, often cause them. One of the primary causes of water leaks in hot tubs is worn or damaged seals around the jets, pump, and other fixtures. These seals can wear out over time due to exposure to heat and chemicals and can lead to leaks.
Cracks in the structure of the hot tub can also cause leaks. Various factors, including impact damage, exposure to extreme temperatures, or improper installation, can cause these cracks.
Steps to Take:
Below are common ways you can repair water leaks depending on the cause of the leak.
- You can replace the seal if the leak comes from a worn or damaged seal around the jets, pump, or other fixtures. This relatively straightforward process typically involves removing the old seal and installing a new one.
- If the leak is coming from a crack in the structure of the hot tub, the crack can be repaired using a patching compound. You can apply the compound to the crack to seal it and prevent further leaks.
- If the leak comes from hot tub pumps not working or other plumbing issues, the pump or plumbing can be repaired or replaced as necessary. This may involve replacing damaged pipes or connections or repairing or replacing the pump.
2. Low Water Flow
A low water flow problem in hot tubs can be caused by various factors, including clogged filters, worn or worn or damaged pump impellers, or low water pressure.
Clogged filters can cause a low water flow problem by impeding water flow through the hot tub.
Worn or damaged pump impellers can also cause a low water flow problem. The impeller is a rotor inside the pump that spins to move water through the hot tub. If the impeller is worn or damaged, it may not force water through the hot tub effectively, resulting in low water flow.
Low water pressure can also cause a common water flow problem. This can happen because of various factors, including clogs in the water supply line, problems with the water supply valve, or issues with the hot tub’s pump or plumbing.
Steps to Take:
There are several ways to repair low water flow in hot tubs, depending on the cause of the problem.
- If clogged filters cause a problem, the filters can be cleaned or replaced. They may need to be replaced if they are too clogged or worn out. Cleaning the filters can be done by removing them from the hot tub and rinsing them with a hose or a filter cleaning solution.
- If a worn or damaged pump impeller causes the problem, the impeller can be replaced by a professional technician. This relatively straightforward process involves removing the old impeller and installing a new one.
- If the problem is caused by low water pressure, the cause of the low water pressure must be located and addressed. This may involve clearing clogs in the water supply line, repairing or replacing the water supply valve, or addressing issues with the hot tub’s pump or plumbing.
3. Heater Problems
Heater problems in hot tubs can be caused by various factors, including malfunctioning thermostats, faulty heating elements, or issues with the hot tub’s circulation system.
A malfunctioning thermostat can cause the hot tub not to heat up properly or to overheat. This can be caused by various issues, such as a malfunctioning thermostat sensor, a faulty thermostat control, or a problem with the hot tub’s control system. A professional technician can diagnose and repair a malfunctioning thermostat.
Faulty heating elements can also cause heater problems in hot tubs. A heating element is the hot tub section that generates heat to warm the water. If the heating element is not functioning correctly, it may not heat water in the hot tub effectively. A professional technician can diagnose and repair or replace a faulty heating element.
Issues with the hot tub’s circulation system can also cause heater problems. This can be caused by clogs in the circulation system, malfunctioning pumps or valves, or problems with the hot tub’s plumbing. The circulation system is responsible for moving water through the hot tub; if it is not functioning correctly, it may not heat water effectively.
Steps to Take:
If your hot tub is experiencing heater problems, the following steps can help you try to diagnose and fix the issue:
- Check the thermostat: Ensure that the thermostat is set to the desired temperature and that the display works properly. If the thermostat appears to malfunction, it may need to be replaced.
- Check the water level: Ensure the water level in the hot tub is correct. If the water levels get too low, it can cause the heater to shut off or not function properly.
- Check the filter: Make sure that the filter is clean and not clogged. A clogged filter restricts the flow of water and causes the heater to shut off or not function properly.
- Check the circulation system: Ensure that the pumps and valves in the hot tub’s circulation system are working correctly. A malfunctioning pump or valve can cause the heater to shut off or malfunction.
- Check the power supply: Ensure that the hot tub is getting power and that the breaker has not tripped.
4. Faulty Jets
Faulty jets in hot tubs can be caused by various factors, including clogs, damage, or wear and tear.
Clogs in the jets can occur due to the accumulation of dirt, debris, or other foreign materials. Clogs can restrict the flow of water and air through the jets, making them less effective.
Damage to the jets can occur due to impact, wear and tear, or chemical exposure. Damaged jets can be caused by physical effects, such as someone accidentally hitting the jet while getting into the hot tub or the jet being damaged during the cleaning process. These damaged jets can be repaired or replaced depending on the extent of the damage.
Wear and tear are a common cause of faulty jets, as the parts inside the jets may wear out over time from regular use. These worn-out parts can affect the jets’ performance, making them less effective. In this case, you should replace the jets.
Steps to Take:
If your hot tub is experiencing hot tub jets not working, there are several steps you can take to try to diagnose and fix the issue:
- Check for clogs: Inspect the jets and ensure they are not clogged with dirt, debris, or other foreign materials. If you find any clogs, use a jet-cleaning solution or a stiff brush to remove them.
- Check for damage: Inspect the jets for any signs of wear, such as cracks or broken parts. If you find any damage, the jet may need to be repaired or replaced.
- Check the water flow: Ensure that the water flow to the jets is not restricted. Inspect the water supply lines and ensure they are not clogged or kinked.
- Check the airflow: Ensure that the jets’ airflow is not restricted. Inspect the air supply lines and ensure they are not clogged or kinked.
- Check the control system: Ensure that the system that operates the jets is functioning correctly. A professional technician can check the control system.
5. Smelly Water
Various factors, including bacteria growth, chemical imbalances, or organic matter build-up, can cause smelly water in hot tubs. Bacterial growth can occur in hot tubs due to a lack of proper sanitation and cleaning. If not adequately maintained, bacteria can thrive in warm, humid environments, such as hot tubs. The bacteria can produce offensive odors and may also be harmful to your health.
Chemical imbalances in the water can also cause offensive odors. For example, if the pH level of the water is too low or too high, it can cause a strong chemical smell. Organic matter such as sweat, lotions, and oils can accumulate in the water and create a breeding ground for bacteria that will produce offensive odors. Organic matter build-up can also cause foul odors in hot tubs.
Steps to Take:
If your hot tub is experiencing smelly water, the steps below can help you to diagnose and fix the issue:
- Check the sanitation: Ensure the hot tub is properly sanitized and cleaned. Use a suitable sanitizer and shock the hot tub regularly as per the manufacturer’s instructions.
- Check the pH level: Test the pH level of the water and ensure it is within the recommended range. If the pH level gets too high or too low, adjust it as necessary.
- Check for organic matter: Inspect the hot tub for any visible signs of organic matter, such as oils, lotions, or debris. Remove any visible organic matter and clean the hot tub.
- Check the filters: Make sure that the filters are clean and not clogged. A clogged filter can trap organic matter and bacteria, leading to offensive odors.
- Drain and refill the water: If the problem persists, consider draining and refilling the water. Make sure to thoroughly clean the hot tub before filling it.
