How do I choose the right Moji hot tub for my needs?

Consider factors such as size, seating capacity, features, and budget. Moji offers a variety of models to suit different preferences.

What do the hot tubs come with?

All Moji hot tubs come with a New Zealand compliant hard lockable cover to shield your tub from harsh outdoor elements and keep the heat in. We also include a startup chemical kit for free.

How can I purchase a Moji hot tub?

Moji hot tubs can be purchased online directly through the Moji website, or alternatively you can contact one of the Moji Team HERE and they will talk you through the options and process.

Where are Moji's hot tubs made?

Our hot tubs are proudly handcrafted in Napier, New Zealand.

What are the health benefits of a hot tub?

Soaking as little as 15 minutes a day in a Moji hot tub can improve your cardiovascular health, help alleviate back and muscle pains, lower your blood pressure, and even burn calories.

What else do I need to consider before I buy?

There are a number of important considerations and preparation actions to be completed prior to delivery. These include hot tub placement, access, foundations, drainage, and electrical requirements for your specific model. Check out our Pre-Delivery Guide for more information.

Do you deliver?

Yes! We offer a range of delivery options, with our standard delivery method including lifting your tub into position (view delivery costs and options). Please note, any delivery or placement methods outside of our standard delivery will potentially incur additional costs.

How long does delivery take?

Delivery times may vary depending on your location and current demand. Moji will provide estimated delivery times upon purchase.

How do I prepare for delivery?

Check out our Pre-Delivery Guide for important considerations and preparation actions to be completed prior to delivery.

Do you install my hot tub for me?

Our hot tubs are designed for easy set-up. We’ve created a straightforward Installation Guide for your reference.

What kind of surface is suitable for placing my Moji hot tub?

Moji hot tubs should be placed on a level, hard, dry surface such as concrete or well-compacted pavers. Grass or dirt surfaces are not suitable.

Do I need an electrician or plumber to set up my hot tub?

If your hot tub requires electrical hardwiring or you’ve opted for a heat pump add-on, we recommend booking your electrician to pre-wire to the isolator switch near where the tubs located. On the day your tubs delivered you will require the electrician to be there to do the final wiring into the controller, they can do this while the tubs filling and then it can be given the required tests by them to be able to fill out an electrical code of compliance to cover their work.

Theres no need for a plumber as all Moji Tubs are just filled from a garden hose.

How do I fill my hot tub?

Follow our guidelines for filling your hot tub safely and efficiently.

How often do I need to change the water?

The frequency of changing the water varies depending on usage and maintenance. We recommend changing your hot tub water at least once every 2 months. Refer to our water care instructions for more information.

What chemicals are recommended for maintaining water quality in my Moji hot tub?

We recommend chlorine or bromine sanitisers for killing bacteria and preventing algae growth. Refer to our water care instructions for detailed guidance on chemical treatment.

What is the recommended maintenance schedule for my hot tub's filter?

Clean the filter at least once a week and replace it as necessary to ensure optimal filtration. Refer to the filter cleaning instructions for detailed guidance.

How often should I test and balance the water in my hot tub?

It’s recommended to test the water regularly using test strips and adjust pH and sanitiser levels as needed. Frequency may vary depending on usage and environmental factors. Refer to our water care instructions for more information.

Heartbeat LED

All SV Mini hot tub packs feature a red flashing heartbeat LED light. The heartbeat LED is located on the main printed circuit board of the hot tub pack itself (hot tub pack enclosure cover needs to be removed).

The heartbeat LED flashes to indicate the current health/status of the hot tub pack. When the hot tub pack is functioning correctly with no errors to report the heartbeat LED emits a single flash in a constant pulse much like a heartbeat (ON, OFF, ON, OFF). If the hot tub pack encounters a fault the heartbeat LED will begin flashing in sequence with the error code number being experienced (i.e. ER2 = ON,ON; OFF ON,ON; OFF).

If the keypad display is ever blank a hot tub user can still determine the health / status of the SV Mini controller by removing a panel from the hot tub skirt and checking the heartbeat LED on the front of the hot tub pack itself.

ER-2 Heater Plug

Problem: No heater sensor communication.

Cause: Heater sensor communication problem. Sensor cable is not correctly connected to hot tub control or is damaged.

Solutions:

  • Turn mains power OFF, remove hot tub cabinet panel and SV Mini enclosure cover;
  • Check heater sensor cable is firmly plugged into hot tub control socket labelled HEATER;
  • Unplug and re-plug heater sensor cable to re-establish connection to hot tub control;
  • Check for damage to sensor lead, replace covers, and test hot tub again; and
  • Contact us if problem is not resolved.

ER-3 Water Prime

Problem: Water prime failed – air detected in heater tube.

Cause: Airlock in pipe work, low water level, dirty filter cartridges.

Solutions:

    • Press Pump A button to retry water prime;
    • Check hot tub water level (refill if necessary);
    • Remove filter cartridges and press Pump A button to retry prime;
    • Bleed airlock from pipe work by slightly loosening couplings on front of filtration pump;
    • Remove filter cartridges and flush water down pipe work with a hose;
    • Contact us if problem persists.

ER-4 Thermal Trip

Problem: Heater thermal trip activated. Heater has been active and has had insufficient water flow over the element. Low or no water flow has caused the heater temperature to exceed its maximum limits and the hot tub control has shut down operation to prevent any damage to the heater unit.

Cause: Low water level, airlock in pipe work, closed shut-off valves, dirty filter cartridges, filtration pump failed, or operation intermittent.

Solutions:

  • Turn mains power OFF and wait 20-30 minutes for element to cool and thermal cut-out device to reset. Then turn power back ON;
  • Check hot tub water level (refill if necessary);
  • Remove filters and clean as per manufacturer’s recommendations or replace cartridges if required;
  • Check under hot tub cabinet to ensure all shut-off valves are in the OPEN position;
  • Bleed airlock from pipe work by slightly loosening couplings on front of filtration pump or by removing filters and flushing water down pipe work with a hose;
  • Contact us if problem persists.

ER-5 Pool Too Hot

Problem: Pool over temperature. Temperature sensor reading > 45°.

Cause: High ambient temperatures (especially in summer months) have caused water temperature to rise above set temp point, excessive filtration time, jet pumps have been operating for extended periods with the hot tub cover still on.

Solutions:

  • Turn mains power OFF, remove hot tub cover, allow hot tub to cool then turn power back ON;
  • Check daily filtration time (refer filtration section) and reduce daily filtration time if required;
  • Check hot tub cover is not resting on topside panel buttons causing jet pumps to start when cover is on. Use keylock function to lock keypad buttons when hot tub not in use;
  • Contact us if problem persists.

ER-6 12V Overload

Problem: 12V (port) current draw over 1A limit.

Cause: Total 12V current drawn by keypad(s), light(s), expansion ports and in-pool temp sensor is excessive, 12V power supply is overloaded, too many LED light bulbs installed, faulty LED light.

Solutions:

  • Turn mains power OFF and restart hot tub to see if problem reoccurs;
  • Perform EPRM software reset to factory defaults;
  • Reduce number of LED lights connected to hot tub control;
  • Systematically unplug lights, keypads, and expansion port loads from hot tub pack (one by one) to identify the faulty 12v device;
  • Contact us if problem persists.

ER-8 Ctrl Fault HVS

Problem: Heater relay is on when it should be off.

Cause: Power surge, periods of low or high voltage, water on hot tub pack terminal block, relay fault.

Solutions:

  • Turn mains power OFF and back ON again to see if hot tub control recovers from ER8 fault;
  • Inspect under hot tub cabinet for evidence of water leaking onto hot tub control. If water present, turn mains power OFF and isolate, then resolve leak, dry up excess water, and allow hot tub control to dry out before restoring power;
  • Contact us if problem persists.
