Before calling in the professionals, there are several common hot tub issues you can troubleshoot yourself with a little know-how and these handy tips.

Heat Not Rising?

  • Check the power: Ensure the dedicated circuit breaker for your hot tub is switched on.
  • Verify the temperature: Double-check that the thermostat is set to your desired temperature.
  • Clean the filter: A clogged filter can restrict water flow and hinder heating. Clean or replace the filter as needed.
  • Reset the GFCI outlet: Sometimes, power fluctuations can trip the ground fault circuit interrupter (GFCI) outlet. Reset it according to the manufacturer's instructions.
  • Consult a technician: If the above steps don't resolve the issue, the heating element might be malfunctioning. Consult a qualified technician for further diagnosis and repair.

Unbalanced Water Chemistry:

  • Invest in a test kit: Purchase a reliable test kit to measure chlorine, pH, and total alkalinity levels.
  • Adjust chemicals: Based on the test results, add chlorine granules, pH increaser/decreaser, or alkalinity increaser/decreaser to bring the levels within the recommended range.
  • Maintain consistent testing: Regularly testing and adjusting water chemistry is crucial for optimal performance and safe use.

Cloudy or Foamy Water:

  • Clean the filter: A dirty filter can trap debris and contribute to cloudy water. Clean or replace the filter as needed.
  • Shock the water: Regularly shocking your hot tub with a chlorine shock treatment helps eliminate built-up contaminants and improve water clarity.
  • Check for leaks: Leaking contaminants can also cloud the water. Inspect for any leaks around pipes, fittings, or jets, and address them promptly.
  • Adjust chemical balance: Imbalanced pH or alkalinity can also contribute to cloudiness. Ensure proper levels through regular testing and adjustments.

Weak or No Jets:

  • Check for air blockage: Sometimes, air can get trapped in the jets, hindering their performance. Turn off the pump, open the air bleed valves on the filter housing, and allow air to escape until water flows steadily.
  • Clean the jets: Mineral buildup can clog the jets. Use a jet cleaner or soak the jets in a solution of water and white vinegar to remove debris.
  • Ensure proper pump operation: If the pump isn't functioning correctly, the jets won't have sufficient pressure. Check the breaker, inspect for clogs in the pump strainer basket, and ensure the pump lid is securely fastened.

Unusual Noises:

  • Consult a technician: Unusual noises can indicate a problem with the pump, such as worn bearings or air leaks. If you suspect a pump issue, consult a qualified technician for diagnosis and repair.
  • Inspect the jets: Loose or damaged jets can also create noise. Tighten any loose jets and replace any that are cracked or broken.


  • Consult the manual: Your hot tub's manual is a valuable resource for troubleshooting common issues and proper maintenance procedures.
  • Seek professional help: If you're unsure about any aspect of troubleshooting or the problem persists, don't hesitate to seek assistance from a qualified hot tub technician.

By following these tips and familiarizing yourself with common hot tub issues, you can often resolve minor problems yourself and keep your hot tub bubbling with relaxation for years to come. Remember, preventative maintenance, regular cleaning, and proper water chemistry are key to avoiding major issues and ensuring a safe and enjoyable hot tub experience.
