What Should I Do If My Hot Tub Jets Aren’t Working

Check for clogged filters, airlocks, or debris in the jet line. You'll need to purge your hot tub jet lines with a jet line cleaner. It's also a good idea to clean your spa filter.

Why Aren’t My Hot Tub Jets Working?

Before diving into the solutions, it’s important to understand the possible reasons why your hot tub jets aren’t working. Identifying the cause will help you find the best fix for your specific issue.

Air in the Lines

One common reason for hot tub jets to stop working is air trapped in the water lines. Air can disrupt the water flow and cause the jets to lose power or stop working altogether.

• Signs of air in the lines: If your jets are weak, sputtering, or completely off, air could be trapped in the system.
  

• Cause: This can occur if the water level is too low, or if there’s a leak in the plumbing.
  

Clogged Jets or Filters

Clogged jets or filters can reduce or block the water flow to the jets, resulting in weak or non-functioning jets.

• Signs of clogged jets: If only some jets are not working or if the water flow is uneven, it could be a clog in the jet or filter.
  

• Cause: Clogs can result from debris buildup, mineral deposits, or dirty filters.
  

Pump Issues

The pump is responsible for circulating water throughout your hot tub, including through the jets. If the pump isn’t working properly, it could prevent water from reaching the jets.

• Signs of pump issues: If you hear strange noises from the pump or notice that the jets are weak or completely non-functional, the pump might be the issue.
  

• Cause: Pump issues can be caused by a faulty motor, worn-out seals, or an electrical problem.
  

Faulty Jet Diverter Valve

A jet diverter valve controls the water flow to different areas of the hot tub. If this valve malfunctions, it could prevent water from reaching the jets.

• Signs of a faulty diverter valve: If you can’t adjust the direction of the jets or if water is only coming from some jets, the diverter valve might be the problem.
  

• Cause: A faulty valve can result from wear and tear or debris buildup.
  

Electrical Problems

Electrical issues can also cause your hot tub jets to stop working. If there’s an issue with the electrical components that control the jets, they may not function as they should.

• Signs of electrical problems: If your hot tub jets aren’t turning on at all, or if the control panel is unresponsive, there could be an electrical issue.
  

• Cause: This could be due to a blown fuse, tripped breaker, or malfunctioning control panel
  

How to Fix Hot Tub Jets That Aren’t Working

Now that you understand some of the potential causes for non-working jets, let’s explore the steps you can take to troubleshoot and fix the issue.

Check the Water Level

Low water levels can cause air to enter the lines, which affects the water flow to the jets. To resolve this issue:

• Check the water level: Ensure that the water level is high enough. The water should cover the skimmer and be within the recommended range for your hot tub.
  

• Add water if necessary: If the water level is too low, add water to the hot tub to bring it up to the proper level.
  

Prime the Pump

If air is trapped in the water lines, priming the pump will remove the air and restore normal water flow.

• Turn off the power: Always turn off the power to your hot tub before performing any maintenance.
  

• Locate the priming valve: Find the priming valve (also known as the bleeder valve) on the pump.
  

• Open the valve: Open the valve to allow water to flow through the system and remove any trapped air.
  

• Close the valve: Once the air is removed, close the valve and turn the power back on.
  

Clean the Filters and Jets

Clogs in the jets or filters can restrict water flow and cause the jets to stop working. To fix this issue:

• Turn off the power: Ensure the power is off before cleaning.
  

• Remove the filter: Take out the filter and rinse it with a hose to remove any dirt or debris.
  

• Clean the jets: Use a small brush or pipe cleaner to remove any debris from the jets. If there’s mineral buildup, use a cleaner designed for hot tub jets.
  

• Replace the filter if needed: If the filter is damaged or overly dirty, it’s time to replace it with a new one.
  

Inspect the Pump

If the pump is malfunctioning, it could be preventing water from reaching the jets. To inspect the pump:

• Turn off the power: Always ensure the power is turned off before performing any maintenance.
  

• Listen for unusual noises: If you hear unusual noises from the pump, it could be a sign that the motor is faulty or the seals are worn out.
  

• Check for leaks: Inspect the pump for any visible leaks, which could indicate a problem with the seals or gaskets.
  

• Consult a professional: If you suspect a problem with the pump, it’s a good idea to call a professional to inspect and repair the pump.
  

Inspect the Diverter Valve

A faulty diverter valve can prevent water from reaching some or all of the jets. To inspect the valve:

• Check the valve: If you can’t adjust the jets or if the water is only coming from some jets, check the diverter valve for any signs of damage or blockage.
  

• Clean the valve: If the valve is clogged, use a mild cleaning solution to clean it. If the valve is broken, it may need to be replaced.
  

Check for Electrical Problems

If you suspect an electrical issue is causing your jets to stop working, you can take the following steps:

• Check the fuse: Inspect the fuse or breaker to see if it has blown or tripped. If it has, replace the fuse or reset the breaker.
  

• Inspect the control panel: If the control panel is unresponsive or malfunctioning, the issue could be with the wiring or the control panel itself. If this is the case, it’s best to consult a professional.
  

Call a Professional

If all else fails and you’re unable to resolve the issue, it may be time to contact a professional.

• Professional inspection: A hot tub technician can assess the pump, jets, diverter valve, and electrical system to identify the issue.

• Pump replacement: If the pump is beyond repair, a technician can help you replace it with a new one.
