Shut off the power to the hot tub at the outside breaker for about 45 minutes. Turn the power back on and check the system. Sometimes this “reboot” procedure clears up the problem.

Turn the power off to the hot tub at the outside breaker: Take out the filter out of the spa (make sure that nothing is floating in the spa that could get sucked into the filter area). After leaving the spa off for 45 minutes turn the spa back on and turn both pumps and air on for 45 minutes.

If the FLO message goes away either replace the filter with a new filter or thoroughly clean your existing (non-disposable) filter. Clean the filter by soaking it in a solution of 16 oz. Filter Clean with 4 gallons of water in a separate container overnight and rinsing with clean water until you see no residue in the rinse water.

If the water has been changed recently and the filter has been cleaned, there may be an air lock. To resolve:

  • Turn off the power at the outside breaker
  • Remove the filter
  • Place a garden hose in the opening where the filter was; this leads into the plumbing.
  • Turn the hose on at full force to dissipate the air bubble.
  • Alternatively, again with the power to the spa turned off, remove the large diverter knob by pulling straight up then loosening the diverter nut to allow the air to dissipate.

Turn off the power to the outside breaker for at least 45 minutes, and then turn back on. This will reset the spa.

Enabling 60 Amp logic on your Sundance Spa will allow pumps, the air blower and the heater to run simultaneously.
880 Series: Place a jumper on JP9 # 7, located ¾ of the way down on the left side of the circuit board.
780 Series: Place a jumper on JP1 # 5/6, located in the top right corner of the circuit board.

Make sure:

  • The water is at a level which covers all of the jets (making sure not to touch the pillow, or overfill). This affects the water flow through the heater.
  • The filter has been cleaned within the last four weeks by soaking it in Filter Clean (if applicable) and that filter is not older than 18 months. In order to test whether or not the filter is the cause of a no-heat situation
    • Turn the power off at the outside breaker
    • Take out the filter out of the spa (make sure that nothing is floating in the spa that could get sucked into the filter area).
    • After leaving the spa off for 45 minutes, turn the spa back on without the filters in the spa to see if it begins heating.
    • If it begins heating you know it is the filter causing the problem.
  • The controls are set in continuous heat mode and/or programmed for several hours of heating.
  • Is Leisure Time Defender used bi-weekly? This prevents calcium buildup on the heater, which will lead to inefficient heat transfer.
  • Use Spa Cleanse at least once a year, prior to draining, to help remove organic build up in the heater.
  • If a Sundance Spa: Check mode. When in ‘Economy’ mode, hot tub models will heat only when jets are activated or during filter cycles. If your hot tub is in Standard mode (models between 2003-2015) the hot tub should be heating properly.
  • If a Hot Spring Spa: Check mode. When in ‘Summer’ mode, hot tub models will heat only when jets are activated or during filter cycles. Some older Tiger River models have heaters with a reset button, refer to owner’s manual for location or other tips.

Ozone humming is normal. It is the vibration of ozone being sucked through the Mazzi Injector.

If the hot tub has no power, or is not heating:

HotSpring Spas: Place a droplight with a 60 or 75-watt bulb inside the access panel over pump one. (Facing control panel, usually behind right wooden section)

Sundance Spas: Place a small, UL listed, space heater into the main equipment area on LOW HEAT, HIGH FAN.

In both cases, make sure neither the drop light or space heater is not touching any components, wires, or insulation and replace the cabinet panel to the best of your ability. Leave the hot tub cover on and fastened to retain as much heat as possible.

All Sundance models are equipped with a safety feature called “Summer Logic”. This feature turns off the circulation pump when the water temperature in the spa rises to 2 degrees Fahrenheit above the set temperature. This phenomenon can occur in warmer weather because the circulation pump adds heat (while running) through the process of convection. If the ambient air temperature is hot, the water does not cool as quickly and retains the heat for a longer period.

Summer Logic disables the circulation pump and the heater to decrease the spa’s water temperature. If the circulation pump is off (no bubbles), the spa is not heating and appears dead. Fill the spa with cool water and change filter cycles from daytime to evening, when the temperature is cooler. Consider running the air bubbles in the evening’s cooler air-with the cover off, as this will assist in cooling the water.

The number one cause of a Moto-Massage jet not working is a clogged filter. Make sure your filter(s) have been cleaned within the last four weeks by soaking in Filter Clean (if applicable) and that the filter is not older than 18 months (unless it is a Tri-X filter). In this case you need to soak the filter if it has been more than three months, if less than three months, please run your filter through the rinse cycle on your dishwasher with NO DISHSOAP and NO DRYING CYCLE.  reword or remove?

A quick test to see if the spa filter is the cause: Turn the power off to the spa at the main breaker (for about 15 minutes) then take out the filter(s) from the hot tub. Make sure that nothing is floating in the spa that could get sucked into the filter area before you turn the breaker back on. Once power is returned, without the filter(s) in, see if the Moto-Massage jet begins operating properly. If it does not fix the issue please contact our Service Department to schedule a repair.

To minimize airlocks in the equipment follow these steps below and turn hose on. This will fill the tub through the heater, pumps, and jets pushing most of the air out of the lines.

    • HotSpring/Limelight/HotSpot/Tiger River Spas: put hose down the center of the gray standpipe in the filter compartment.
    • Sundance Spas: take out the filter(s) and put the hose into
      • the opening on the side wall of the filter compartment (if an 780, 880, or 980 series hot tub)
      • the filter bucket open (at the bottom of the filter well)
  • Fill the spa to the top of the highest jets.
  • HOT SPRING ONLY:
    • For 240 v spas, turn on the 20 amp breaker and run jets 10 mins, then turn on the 30 amp breaker and continue to run jets 30 min.
    • For 120 v spas, plug in and immediately turn on jets for 10 minutes. Either way, turn the diverter handle(if applicable)slowly 360°(Vista, Grandee GG version, Grandee CC version, Envoy, Siberian, Caspian, Pulse, Flair & Glow models, turn on the 30 amp breaker first, run jets for 10 mins, then the 20amp)
  • Did you remember to put the hose down the center of the gray standpipe/filter area and clean your filters?
  • If No, the pump may have an airlock, or the filters may have tripped the hi-limit. Reset the hi-limit (Refer to Owner’s Manual) and place a hose down the gray standpipe (just like when you fill your spa) to flush out the air. If you have an ozone unit, look for a steady stream of bubbles, if you do not have an ozone unit, look for the curling/rippling of the top of the water.
  • Make sure there is no foreign debris in the spa, pull filters out and replace caps. Run jets 30 min, turn the power to the spa off for 1 minute, and then restore power.
  • If red light stops blinking the problem has been corrected.
  • If red light is still blinking, go to online service request form.
  • Turn power to the spa off for 1 minute, then turn power back on. For 240 v spas, turn on the 20 amp breaker and then turn on the 30 amp breaker. For 120 v spas, plug in.
  • If light continues to blink, go to online service request form.

This indicates low water flow, follow procedures for Blinking Red light

If winterizing the hot tub: follow detailed steps in Owner’s Manual or contact our store for assistance. Damage caused to your spa by improper winterizing is NOT covered by your spas’ warranty. New England Spas offers a Winterizing and Un-Winterizing service. As the months get colder NES may not be able to complete this service. We recommend you consider and schedule a call prior to November 30th.
