Troubleshooting/FAQ
Got questions? Don't worry we have at least a few answers.
Why should I consider a hot tub?
Warm water therapy has proven to be beneficial in healing, relieving and preventing injuries. For many people, it also helps to ease the stresses of everyday life, joints, and muscles as well as provide a great environment to connect with family and friends.
Is it difficult to install a hot tub? Where’s the best place to put it?
The answers to these are dependent on each individuals situation, but the bottom line is that a hot tub is actually relatively easy to install. Sufficient clearance is needed to transport the tub to your pad. Afterwards a qualified electrician will need to wire up the tub, and then only a garden hose is needed to fill it up!
Is taking care of a hot tub difficult?
Unlike most brands of hot tubs, taking care of a Master Spa is very easy. Every Master Spa features a patented, time-saving Eco Pur Water Purification System, which drastically reduces the time and amount of maintenance needed on your hot tub.
Are Master Spas hot tubs energy efficient?
Yes. Master Spa's are built to exceed the energy standards set by the California Energy Commission (CEC). Master Spas uses Icynene foam, which will not lose its insulating value for the life of your spa, while other brands using less expensive urethane based foams may lose up to 50% of their R-value (the measure of an insulation's ability to resist heat traveling through it) in as little as two years. Icynene is also environmentally friendly, as it does not emit gas. The Icynene insulation is sprayed onto the shell and plumbing of every spa and expands to fill every area ensuring you have the most energy efficient hot tub on the market. Cover locks are also provided to further increase your energy savings.
Does my hot tub/home need to have any special plumbing installed?
No. You will never need any special plumbing run to or from a Master Spa. All you need to do is put a garden hose over the edge to fill it up. A small pump is recommended for draining, but not necessary.
What type of power does a hot tub require?
Most hot tubs require a dedicated 220V/50a system. Each tub's owner manual can help you to determine exactly what you’ll need in addition to a qualified electrician. Some smaller hot tubs may be hooked up to a dedicated 110V/15a outlet. Hot tubs hooked up to 110V will generally have fewer therapy jets and smaller powered pumps and heaters.
How safe is a portable spa?
Safety is absolutely the top priority at Master Spas. That's why every Master Spa is Electric Testing Labs (ETL) marked and built to stringent Underwriters Laboratoris (UL) safety standards. Inertek, who provides the ETL mark, is the worldwide leader in safety testing. Each Master Spas model has been submitted to Inertek for testing and approval. Additionally, Inertek performs quarterly surprise inspections at the Master Spas facility. This gives you peace of mind. As with any other product that involves water, you should follow all electrical precautions outlined in our owner's manual and your local electric code. Even though our portable spas come with locking covers, you should never allow children to play around the spa without adult supervision.

Nothing on the spa operates
- Check the control panel display for any messages. If there is a message, refer to the diagnostic section on that model hot tub. There you will find the meaning of the message and what action is to be taken.
- If there is no message on your control panel, check and reset the GFCI* and house breaker. (*The GFCI should be located in a weatherproof box close to the spa, but no closer than 5 ft.)
- If the spa does not respond, contact your dealer for service.
Pumps do not operate
- Press the "Jets" button on your control panel.
- If you hear the pumps trying to operate:
- Check that all the slice valves are open.
- The pump(s) may need to be primed.
- Check that the air controls are open.
- If you do not hear anything from the pump, contact your dealer for service.
Poor jet performance
- Make sure pump is operating.
- Check that the water level is adequate (up to minimum safe water level).
- Make sure the jets are open and the air controls are open.
- Check for dirty filters. Clean if necessary.
Hot Tub not heating
*If the hot tub heater has failed, the majority of the time it will trip the GFCI breaker. If the hot tub is not heating and has not tripped the breaker, please follow these steps:
- Check the control panel display for any messages. If there is a message, refer to the diagnostic section in the Spa Controls section of your owner's manual. There you will find the meaning of the message and what action is to be taken.
- Check water set temperature at control panel.
- Check for dirty filters. Clean if necessary.
- Check "heat mode" the hot tub is set in. Hot tub should be in ready/standard mode.
- Check the control panel for heater light indicator and/or thermometer icon. If the light is on or the indicator icon is moving, the hot tub should be heating. Wait a reasonable amount of time (approximately 1 hour) to see if the water temperature is changing. During this time, make sure the insulating cover to your spa is on and secured.
- Reset power to the spa at GFCI breaker.
- If hot tub is still not heating, contact your dealer for service.
GFCI is tripping
The tripping of the GFCI may be caused by a component on the spa or by an electrical problem. Such electrical problems include, but are not limited to, a faulty GFCI breaker, power fluctuations or a simple miswire. It may be necessary to consult an electrician if your local dealer recommends doing so.
