Hot Tub Jets Not Working

• Make sure your hot tub is powered on: Your hot tub's jets won't power on unless the rest of your hot tub is getting power. Check your control panel for signs of life. If you find that your hot tub is not getting power, then check out our 'Hot Tub Not Powering On' page.
• Make sure your jets are on at the control panel: For the jets to work, they will need to be turned on at the control panel. Push your control panel's jet button, and make sure that it activates. If not then the likely suspect is your control panel.
• Check for Error Messages: Most modern hot tubs can give error codes if something is wrong. Before continuing, look for error codes, or any blink codes that might explain the issue.
• Power Cycle your Hot Tub at the GFCI Breaker: A simple restart can resolve temporary issues with just about any device, and hot tubs are no different. Now, every spa is different, and you might want to refer back to your hot tub's owner's manual for specific instructions, but most hot tubs will need to be powered off at the GFCI Breaker. Switch the breaker off for 10 minutes, switch it back on, and see if the temperature increases.
• Attempt a Hard Reset: Like other electronics, sometimes a hard reset is all that is needed to fix an issue. Check your hot tub's user manual for instructions on restarting it correctly, but generally, you can reset it at the GFCI breaker.

A hot tub uses a pump to circulate water through a heater and back into the tub, maintaining a consistent, warm temperature. If there's no flow or the flow becomes blocked, the water can't cycle through your system. Typically, this shows itself as the error code FLO.

• Fill your Hot Tub all the way: If the water level in your hot tub is too low, water won't circulate through your system, causing your heater to become overloaded and switch off. This will also prevent the jets from being able to function. Check your manufacturer’s recommendations for the proper water level.
• Clean or Replace your Filters: If your hot tub's filters become blocked with dirt and debris, water will not be able to flow through your system. Properly clean your hot tub's filters, or replace them if you notice any damage.
• Remove Air from the Pipes: If you've had to drain and refill your hot tub, Air can become trapped inside your system, leading to an airlock. Remove your hot tub filter and turn the jets on for a few seconds to clear out any airlock.
• Unclog your Pipes: Clogged water pipes can also prevent your hot tub from heating up properly. You can clean your pipes using System Flush or another hot tub flush product. You may also want to ensure that limescale hasn't built up in your system.

In some instances where your hot tub's jets are not working, try checking if they are blocked with any debris.

• Remove and directly look at the Jet Nozzle: Look directly at your jet nozzles to see if there is any dirt or debris lodged inside the tip. If the tip is blocked, then you will need to remove it and clean it before reattaching.
• Check the jet nozzle for any physical damage: A damaged jet nozzle will prevent water from flowing through it effectively. If the nozzle or any other part of the jet is damaged, then the jet will need to be replaced.
• Securely reattach your nozzle: After inspecting and cleaning all your jets, securely reattach them and tighten them as securely as possible. This process may vary depending on the model of your hot tub.

If your pump isn't running correctly, then this can prevent water from flowing throughout your hot tub, causing your jets not to run. If you notice any of the following from your pump, you might need to source parts, or in the case of older hot tubs, find a replacement pump.

• Listen for Pump Failure Symptoms:
  • The motor is humming but not turning. This can indicate a frozen shaft, bearings, impeller, or defective starting capacitor.
  • Winding noises from worn bearings. If the bearings on the impeller become worn, this can impact the pump's effectiveness and prevent water from flowing through your system.
• Look for leaks under the pump. Bad or damaged gaskets can cause your pump to leak water and prevent it from functioning normally.

If you are not hearing anything from your pump, you should ensure the pump is getting power.
