The QEnergySpa is easy to use and once you are familiar with the basic principles, it becomes second nature. In the event that you are experiencing some difficulty, the following guide will assist.

As long as effervescence is visibly emitted from the Orb, it will function and produce the results as designed.

Troubleshooting Guide





Possible solution

  • No lights on power supply at all. (All models).

  • No power source.

  • Ensure that the unit is plugged in at the wall and switched on.
  • Ensure that the power supply’s on/off switch is on.

  • Fuses are blown.

  • Replace both of the fuses at the back of the unit with 2 Amp fuses (amperage is etched on the metal of the fuse).
  • Internal power failure.

  • Please call your nearest QtheExperience service centre for assistance.

  • Power light is on, output light is off. (Models 3100 and 2500 only).

  • Front/output fuse has blown.

  • Push-in and unscrew the front fuse holder in an anti-clockwise direction and replace with a 4 Amp fuse.

  • Internal power has failed.

  • Please call your nearest QtheExperience service centre for assistance.

  • Front fuse blows continuously (Models 3100 and 2500).

    The code ‘Fo’ is displayed on screen (model 4105 only).

  • Power light, output light and system light are all on. Still no activity.

  • The Orb does not appear to produce bubbles or effervescence (All Models).

  • There is problem with the either the Orb assembly, the Cable connections or the water conductivity.

  • Internal power has failed.
  1. Ensure that the Orb Cable plug is making proper contact within the socket of the power supply and that the locking sleeve is locked in place by a clockwise turn.

  2. Ensure that the connectors on the Orb end of the Cable (the 'Mohawk') are not excessively worn and making proper contact with the brass rod protruding from the top of the Orb and the eyelet of the positive track (protruding at the side of the Orb).

  3. Check that the positive track is installed correctly, touching the positive rings only.

  4. Check the Orb is assembled correctly. Buttons (with the brass rods) are pointing away from the Centre Module.

  5. Check for loose parts within the Orb.

  6. Inspect the Rings & Track within the Orb and replace them when visibly pitted and or worn.

  7. Replace water and adjust with 'Conductive Agent' to correct the conductivity. Also see below, too conductive water (if fuses blow continuously).

  8. Replace front fuse with a 4 Amp fuse.
  9. If none of the above steps identifies and resolves the problem, please call your nearest QtheExperience service centre for assistance.

  • The Activity level lights are in the excessive range (Models 3100 & 2500).

  • The display panel reads ‘Hi’ (Model 4105).

  • The water is too conductive.
    • Internal power has failed.
    1. Select a lower setting (Models 3100 & 2500).

    2. Dilute with tank or distilled water or replace water and start again.

    3. Turn unit off and count to ten before turning unit on again. This allows the 4105 to select a lower setting. (4105 only).

    4. If the excessive light is illuminated and the highest 'water quality' of 3 bars is also illuminated; turning the unit off and adding a little more salt, forces the unit to select a lower 'water quality' setting when it is turned on again. The unit should then show a lower reading on the display panel.  (4105 only).
    5. If none of the above steps identifies and resolves the problem, please call your nearest QtheExperience service centre for assistance.

    • Cannot insert Orb Cable plug into power supply (all models).

    • Check that the semicircular indentation on the plug is lined up correctly with the same on the power supply.

    • Check that there is nothing impeding the plug.

    • Check that the pins in the plug are not bent.

    • The Orb Cable plug falls out of the socket (all models).

    • The code ‘nc’ and/or 'Sd' is visible on the display panel (model 4105 only).

    • The plug is not locked in place at the socket by the clockwise turn of the locking sleeve.

    • Push the DC output plug into the socket as far as it will go without force and lock the locking sleeve in place by a clockwise screw action.

    • The display panel reads ‘go’ (Model 4105 only).

    • The unit has gone through its initialisation sequence, has selected the water quality and set the time of 35 minutes.

    • Press The Green Start Button if you are having the standard 35 minute session.

    • To reset the timer, press mode button repeatedly until the timer button lights up and the number 35 appears on the display panel. Pressing the set button will make the units timer go down in 5 minutes increments. Wait for unit to say 'go', then press the green start button.

    • The display panel reads ‘Fi’ (Model 4105).

    • Internal fuse blown.

    • Please call your nearest QtheExperience service centre for assistance.

    • The display panel reads ‘Sd’ (Model 4105).

    • Self diagnostic mode.

    • Check connections with Orb, water and Cable. Please see the 9 steps above to identify the problem.

    • The display panel reads ‘--’ (Model 4105 only).

    • You have pressed mode button twice, the action light is on. The system is operating normally.

    • Press the 'mode' button for a different display mode if you wish. Enjoy your session.

    Q Tech recommends the use of a surge protector with the unit at all times.
