I received my brand new ez spa today and once I got the water in and pushed test on the gfci the spa came on and so did the jets. I understand that the motor needs to run to heat the water but does the jets run the whole 20 hours it may take to heat the water up to temperature?

First, check to see if the circuit breaker feeding the spa is turned on. Push the breaker handle firmly to the off position then back on. Next check the GFCI protector(if a gfci circuit breaker isn't used). It could be an integrated part of the cord, a gfci receptacle or located in the control panel. Once you locate it press the test button then the reset button. If these proceedures do not correct the problem, it is time to call in an electrician or spa tech.

Do you have 2 GFCI on same circuit? use only 1.
Check for short on spa light.

Typically you want pool and spa lights connected to low voltage (12V ac) transformer

26 Installing two pole GFI breaker

I'm not clear on why you can't use a GFI Breaker. Has someone said this to you, or have you tried using a GFI and it didn't work? Does the heater run off 120 v or 240 v?

The threaded knob should not be related to the problem, it just controls how much air gets mixed into the water jets. One possibility is that the electricity is off. These tubs should receive power through a Ground Fault Circuit Interrupter (GFCI) type of circuit breaker for your protection from electrical shock. Check your circuit breaker panel(s) for a breaker with a little square white or yellow "test" button. Refer to the label (if it is there) to see if it refers to "tub" or "spa" or "bath" or something like that. You may have to turn the breaker handle off (push extra hard to make it reset) and then back on again. If the breaker handle is in the "on" position and the "test" button does not "trip it off," call an electrician. If no luck there, check the bathroom for an electrical outlet with GFCI protection, again looking for white or yellow (or red) buttons - one should be engraved "test" and the other "reset" as the electrician (I hope it was an electrician) may have supplied the tub from this outlet (not actually up to code). Plug an appliance or light into the outlet. If it doesn't work, push the reset button on the outlet and test again. If working, now test the spa. If that doesn't work, test every other GFCI outlet you can find - in the kitchen, other baths, garage, outdoors, basement, etc. using the same testing procedure. If you find a GFCI breaker or outlet "tripped" that restores the tub, that indicates there is something wrong with your electrical system that could cause you to get electrocuted, and requires that you hire a qualified electrician to investigate the problem. The same is true for any GFCI outlet that does not "trip" and/or "reset." If this doesn't fix the tub, the problem may not be electrical but some other problem with the system, indicating a plumber or spa tech may need to be consulted. Note: these GFCI breakers and outlets are supposed to be tested and reset once every month. How many of us do that? Well, at least as often as we test our smoke detectors, I suppose.

It can take up to 24 hrs according to the manufacturer. It heats the water by overheating the motor by the water jacket around it or by cavitation of the water. Depending on how old it is. I have had one for a few years. Once the water gets up to temperature it can maintain it.

This is normal with the dream maker spa. The dream maker spas are poorly insulated, and only run 120 volts with a very small heater.
When the unit is first filled, the hot tub will not heat full time either. Most new hot tubs will have freeze protection below 50 degrees F. They will recirculate automatically using the friction and the pumps heat to warm the water above 50 degrees, and then the heating unit will kick on. These hot tubs do not heat while the jets are on high either, so once you are in it using the jets on high, the temperature will start to fall.

Now that you are up to 80 degrees, it should heat up fairly quick however.

This is a GFCI and will trip at the least bit of water at the plug or at the wiring inside the spa controls. Just go through the system and make sure all is dry. Use a hair dryer in the outlet and on the controls and wiring. If you still have problems you may need to call an electrician.

FOR MOST OF YOUR SPAS YOU SHOULD HAVE A OUTSIDE EMERGENCY SHUTOFF BOX NO CLOSER THEN 5 FEET FROM THE WATER LINE(YOU SHOULD NOT BE ABLE TO SIT IN THE SPA AN BE ABLE TO REACH OUT AN TOUCH THE EMERGENCY SHUTOFF) AN NO MORE THEN 100 FT AWAY FROM THE SPA. IT ALSO DEPENDS ON WHAT BRAND AN WHAT VOLTAGE YOU WILL BE SETTING IT UP AT MOST OF YOUR SPAS TODAY R CONVRTBLE FRM 110 TO 240V. MOST 110 ARE EASY SHOULD JUST BE A GFCI PROTECTED PLUG THAT YOU WOULD HAVE TO PLUG IN(ALWAYS SMART IF ITS A PLUG IN, YOU RUN A SEPERATE BREAKER AN LINE OUT TO A ALL WHEATHER RECPT. TO PLUG THE SPA INTO) THE PLUG COMING FROM THE SPA SHOULD BE A GFCI PROTECTED PLUG LIKE YOU WOULD SEE ON MOST HAIR DRYERS. 240V ALSO DEPENDING ON WHAT TYPE A SPA U NEED THAT EMERGENCY GFCI PROTECTED BOX OUTSIDE(MOST GOOD DEALERS WILL OFFER YOU THIS BOX WHEN YOU BUY THE SPA) BEACUSE ALL BRANDS WILL BE HARDWIRED IN A DIFFERENT WAY SOME REQUIRE A DOUBLE POLE GFCI 30AMP BREAKER FOR JUST THE HEATER AN A SINGAL POLE GFCI 20AMP FOR THE PUMPS ALWAYS WANT THE GFCI OUT AT THE SPAS OUTSIDE SHUTOFF BOX INSTEAD OF IN THE MAIN BREAKER BOX BUT LIKE ALWAYS REFER TO THE MANUEL AN HIRE A ELECTRICIAN WHO HAS DONE SPAS B/4.

The Fantasy has a drain located in the toekick of the spa. You have to first remove the drain cap, attach a hose if you wish, spin the outer black ring counter clockwise to start the water flow, then pull the outer ring out away from the tub to increase the drain to full flow.
I understand that a screw driver is often needed to pull the outer ring out to achieve full flow. Therefore, I suggest another method. Take a garden hose and place it in front of the jet while the spa jets are on. This will force water flow thru the hose and prime the hose. Once you see water running from the other end of the hose, drop the hose in front of the spa jet into the footwell and as long as the loose end is lower than the end in the footwell, a siphon will drain the spa as fast as the spa drain will. Remember to turn off electric to the spa once you have established a siphon. You may have to bucket the last bit of water in the footwell. Goodluck.
