Common Issues & Hot Tub Troubleshooting Steps

Hot Tub Not Heating Properly

When your hot tub is not heating properly, it can put a damper on your relaxation time.

There could be several reasons behind this issue, but the good news is that many of them can be easily resolved with a few simple steps.

Follow our guide below to troubleshoot and fix the problem:

  • Check the Power: Start by ensuring that the hot tub is receiving power. Check if the circuit breaker has tripped or if the GFCI (ground fault circuit interrupter) has been triggered. Reset the breaker or GFCI, if necessary, and see if the heater starts working again.
  • Inspect the Thermostat: The thermostat controls the temperature of the hot tub water. Make sure it is set to the desired heat level and functioning correctly. If the thermostat appears to be faulty, you may need to replace it.
  • Examine the Heating Element: Over time, the heating element in your hot tub can accumulate mineral deposits or become corroded, resulting in poor performance. Turn off the hot tub’s power supply, drain your spa, and remove the access panel to locate the heating element. If you notice any signs of damage or buildup, clean or replace the heating element as necessary.
  • Test the Hi-Limit Switch: The hi-limit switch is a safety device that shuts off the heater if the water temperature gets too high. If the switch is malfunctioning, it may be causing your hot tub to not heat properly. To test the switch, use a multimeter to check for continuity. If it fails the test, replace the hi-limit switch.

If you require further assistance or if the issue persists, don’t hesitate to reach out to the experienced team at Aqua-Tech for expert advice and support.

Water Chemistry Imbalances

Maintaining proper water chemistry is essential for the overall health and enjoyment of your hot tub.

Imbalances in pH levels, sanitizer levels, and total alkalinity can not only affect the clarity and cleanliness of the water but also have negative effects on your skin and the durability of your hot tub components.

Here are some common water chemistry imbalances and DIY solutions to help you restore balance:

Understanding pH Levels:

  • pH levels measure the acidity or alkalinity of the water and should ideally be maintained between 7.2 and 7.8 for hot tubs.
  • Low pH levels can cause irritation to the skin and eyes, as well as corrosion of metal parts. High pH levels can lead to cloudy water and reduce the effectiveness of sanitizers.
  • To lower pH levels, add a pH decreaser according to the manufacturer’s instructions. To raise pH levels, use a pH increaser.

Balancing Sanitizer Levels:

  • Sanitizers like chlorine or bromine are crucial for killing bacteria and maintaining clean and hygienic water.
  • Low sanitizer levels can result in bacterial growth, while high levels can cause eye and skin irritation.
  • Regularly test the sanitizer levels using test strips or a digital tester and adjust accordingly by adding more sanitizer or reducing the dosage.

Total Alkalinity:

  • Total alkalinity acts as a buffer to prevent dramatic changes in pH levels.
  • Low alkalinity can make it difficult to maintain pH levels, leading to corrosion and degraded water quality. High alkalinity can cause cloudiness and scaling.
  • Test the total alkalinity using a testing kit and adjust it using alkalinity treatment products as required.

Remember to regularly test and monitor water chemistry levels using reliable testing kits or digital testers.

Proper water care, including regular water changes and filter cleaning, will ensure that your hot tub water remains clear, balanced, and safe for all users.

Jets Not Working

Hot tub jets are an essential component of enhancing your relaxation and hydrotherapy experience.

However, it can be frustrating when you notice that the jets in your hot tub are not working properly.

Luckily, there are several troubleshooting steps you can take to identify and resolve this issue without the help of a professional.

Here are some common causes for jets not working and how to fix them:

1. Clogged Jets:

Over time, debris, dirt, and minerals can accumulate and clog the jets, preventing proper water flow. To address this issue:

  • Turn off the hot tub, drain it and remove the faceplate or jet ring surrounding the affected jets.
  • Inspect for any visible blockages, such as hair, leaves, or gunk, and use a small brush or toothbrush to gently scrub away the buildup.
  • If the clog is more severe, use a small pin or needle to carefully unclog the individual jet nozzles.
  • Rinse the jet parts thoroughly and reassemble them, ensuring a secure seal.

2. Airlock:

Sometimes, air can become trapped in the plumbing lines, causing a disruption in water flow to the jets. To solve an airlock issue:

  • Check your hot tub’s water level, as low water levels can contribute to airlocks.
  • Locate the air bleed valve, typically situated near the hot tub’s pump or close to the heater.
  • Open the valve briefly to release any trapped air, allowing the water to flow freely through the jets once again.

3. Pump or Motor Problems:

If none of the above solutions resolve the issue, it’s possible that a malfunctioning pump or motor is to blame.

In this case, it may be best to consult a professional hot tub technician who can diagnose and repair the problem.

Leaks and Plumbing Issues

Leaky hot tubs and plumbing issues can be a major headache for owners, but fortunately, there are steps you can take to identify and fix these problems.

Here, we will explore the different types of leaks and plumbing issues you may encounter, along with tips to locate and remedy them.

Different types of leaks:

Leaks in hot tubs can occur in various areas, including the shell, plumbing connections, and equipment.

Understanding the source of the leak is essential for effective troubleshooting. Here are some common types of leaks you may come across:

  • Shell leaks: This can be caused by cracks or punctures in the hot tub shell. Inspect the interior and exterior for any visible damage or signs of water leakage.
  • Plumbing leaks: Leaks can also occur at the plumbing connections, such as the pump, filter, or heater. Look for dripping or wet areas around these components.
  • Equipment leaks: Leaks can arise from faulty seals or gaskets within the hot tub’s equipment, such as valves or unions.

Locating and fixing leaks:

Once you’ve identified the source of the leak, you can take steps to address it. Here are some troubleshooting methods to assist you:

  • Shell leaks: For minor cracks or punctures, epoxy or hot tub repair putty can be used to seal the damaged area. If the damage is extensive, it’s best to consult a professional for repairs or potentially consider replacing the hot tub.
  • Plumbing leaks: Check the connection points carefully and ensure they are tightened properly. If the leak persists, consider replacing the faulty fittings or consulting a professional.
  • Equipment leaks: If the leak originates from a faulty seal or gasket, consult the manufacturer for replacements. The component may need to be disassembled and resealed with a proper sealant, such as plumber’s tape or silicone.

Remember, if you’re unsure about troubleshooting or fixing a leak or plumbing issue, it’s always best to seek professional assistance to prevent further damage.

Electrical Problems

Electrical problems can be concerning and even dangerous when it comes to your hot tub.

Whether you’re experiencing issues with the control panel, lights, or jets, it’s essential to prioritize safety when dealing with electrical components.

Here are a few tips and troubleshooting steps to help you resolve electrical problems in your hot tub.

1. Safety First

Before delving into troubleshooting electrical problems, always ensure your safety by following these precautions:

  • Before inspecting any electrical components, turn off the power supply to your hot tub. This will help prevent any risk of electric shock.
  • As you handle electrical components, make sure your hands are dry.
