Internal Staining

One of the most common issues Softub owners face is staining on the internal lining of the tub. While this doesn't cause any harm, it can be visually unpleasant. Staining typically occurs after a few years of repeated use or when purchasing a secondhand Softub. Fortunately, there are ways to remove or minimize these stains.

How to Remove Staining

  • Scrub and wipe down the tub: Many people have had success removing stains by giving the tub a thorough scrub using washing or dishwasher tablets.
  • Use white vinegar: White vinegar can effectively charge the particles in the stain, making them easier to remove. Simply apply white vinegar to the stained areas and scrub gently.
  • Acceptance: In some cases, stains may be stubborn and resistant to removal. Despite your best efforts, you may need to accept that certain stains cannot be completely eliminated.

Wrinkled Floor

Another common problem with Softubs is a wrinkled floor. This issue can occur in both older, secondhand Softubs and new ones. Wrinkles often develop when the tub is placed on an uneven base during installation. Fortunately, there are several methods to address this problem.

How to Fix a Wrinkled Floor

  • Foam floor protector or supportive base: Placing a foam floor protector or a supportive base under the tub can help reduce creasing and wrinkles. These accessories allow the tub to properly expand when filled and heated.
  • Manual leveling: Add an inch or two of water to the tub and use your bare feet to level out the wrinkles. Start from the middle and work your way to the outer rim, gently pulling the wrinkles apart.
  • Patience: In some cases, waiting can be the best solution. With repeated use, the Softub should naturally expand and fix the creases on its own. Remember, wrinkles do not impact the tub's performance; they are primarily cosmetic.

Tub Floor Slopes

Softub floors are prone to sloping or slanting, which can be a common problem. This issue often occurs when the hot tub is not set up on a foam base or a level floor. Slopes can also result from excessive loading or the introduction of large, heavy objects into the tub. Here's how to address a sloping Softub floor.

How to Fix a Sloping Softub Floor

  • Adjust the base or floor: If the sloping floor is due to an uneven base or leveling issues, simply moving the tub to a sturdier location can resolve the problem. Alternatively, consider using a foam floor protector to help maintain a level surface.
  • Counteract water displacement: If excessive load has caused the sloping, adding additional ballast to the side of the Softub can help counteract the effect of water displacement and restore balance.

Air Loss

Air loss is sometimes reported as an issue with Softubs, but it is often a normal part of the system's operation. When the Softub is turned on, the pressure gauge needs to reach a certain level, which can take some time. After a few days, the pressure may decrease, and air naturally escapes through the tub's overflow. Here's what you need to know about air loss in Softubs.

How to Address Air Loss

  • Allow the Softub to self-regulate: If the air pressure becomes too low, the Softub will automatically top itself up. Alternatively, you can manually add air to the tub if necessary.
  • Check for leaks: While air loss is typically normal, it's essential to ensure there are no leaks in the tub or its plumbing. If you suspect a leak, contact your dealer for further assistance.


Softubs can occasionally experience leaks, either from the pipes and plumbing or from the tub itself. In some cases, the leaks may be due to loose bolts or clamps that can be tightened. However, more severe leaks may require professional service. Here's how to address leaking issues in Softubs.

How to Fix a Leaking Softub

  • Check motor unit and hose clamps: If the motor unit is leaking or if you notice water around the tub's connection points, check the hose clamps and ensure they are tight. Additionally, inspect the motor unit for any casual moisture caused by condensation. Dry the area and tighten the clamps if necessary.
  • Cracked pipes: Leaks can occur from cracked pipes, especially if the Softub has been left full over winter and the pipes have frozen and cracked. If you suspect cracked pipes, contact your dealer for professional service or replacement.

Technical Problems

In addition to the common plumbing and structural issues, Softubs can also experience various technical problems. These issues may include the tub turning on and off, control panel malfunctions, jets not working, or the motor failing to run. Here are some troubleshooting tips for these technical problems.

The Tub Keeps Turning On and Off

  • Normal functioning: Sometimes, the Softub turning on and off is part of its normal operation, particularly during the ozone-adding process. This process occurs during heat calls and filter cycles, and the air control may turn on and off intermittently.
  • Circuit board or relay error: If the tub's pump is turning off and on in short cycles, it could indicate a circuit board or relay error. In this case, professional service from a dealer is necessary.

The Control Panel Stops Working

  • Power supply issues: The most common reason for a faulty control panel is a power supply problem. Check the ground fault circuit interruption (GFCI) and ensure it hasn't tripped or is receiving sufficient electricity. Reset the GFCI and test the control panel. If the issue persists, try plugging the tub into a different socket with the required power output. If all else fails, contact your dealer for further assistance.

Jets Stop Working or Malfunction

  • Jets won't activate: If the jets aren't activating, check the voltage supply and ensure there are no mechanical problems with the GFCI or motor. Also, make sure the tub has reached the desired temperature before expecting the jets to activate.
  • Weak jets: Weak jet flow can be caused by air or solid obstructions in the plumbing. Ensure the jets are turned on and the water height is sufficient. Check for any blockages in the suction inlets and clear them if necessary.
  • Jets lost power while operating: If the jets suddenly lose power, there may be an obstruction in the pipes or motor. Inspect and clean the filter, suction inlets, and plumbing. If the issue persists, contact your dealer for further assistance.
  • Jets won't turn off: If you're unable to shut off the air to the jets, it may indicate a problem with the control valve. Try turning the air control on and off a few times. If the issue persists, contact your dealer for assistance.
  • One jet lost power: If only one or a few jets have stopped working, there may be an obstruction in the affected jet(s). Inspect and clean the jets, removing any debris or blockages. If the problem persists, contact your dealer for further assistance.
