Questions about Pool Repair? Ask an Expert Online.
Hi, This is Doug. I'm happy to try and answer your questions. Please be as specific about them as possible.
Are you saying that it doesn't maintain any heat until you hit one of the buttons?
Or does it maintain heat all the time, just not the temp that you have it set on?
I’d love to help you with the issue and I think I can help you find the parts you need if you’ll send me the Make, Model and serial number of the spa as well as any controller box ID information as it’s frequently made by a company other than the spa manufacturer and even then they use alternating brands of controllers. Pictures would be good as well if you have them and please the age of the spa would be great !
If it's the latter of the situations in the above questions, then it's most likely that your temp sensor is bad. If you can send me the model name and number of the eq. pack as well as the spa information Model, yr. manufactured, I can help you much better as some older models have mechanical thermostats which have a combination temp sensor/ temp. setting replacement part.
First of all I want to ask you for safety’s sake:
Don’t attempt any instructions you’re unsure of your ability to safely complete. Saving a few bucks isn’t worth risking your life. Water and electricity is a dangerous combination!!!
***Whenever I suggest that you to do anything with the wiring or with opening or checking electrical connections or fixtures please be sure that you:
a) Please unhook the main controller box and all other fixtures from the power source via the plug in, the breaker or un-wire the spa from the power supply.
b) After doing so, then wait for 5-10 minutes before proceeding with any further instructions. Read all instructions fully before commencing on diagnosis work!

i will respond tomorrow with pertinent info. i do know it is a Coast Spas unit purchased about 5 years ago
Ok, Looking forward to hearing back from you.
the unit maintains temperature around 75 degrees. does not heat up unless you hit the high pump buttons. unit is a coast spas sound waves paradise model nwp-54 purchased 5/24/07
any answers yet?
Sounds like it definately may be the flo switch on the spa not allowing the heater to run while on the lower pump setting. It doesn' seem as though it's bad as it still does work when the pump is producing additional pressure on high speed. Most are adjustable some are not. Do you think you can find the flo switch and if so are you comfortable with adjusting it?
i replaced the flow switch recently as the original was leaking. there is an adjustable screwslot in the top. it may be screwed all the way down
i adjusted the switch all up and all down. there was no effect. the temperature still maintains aroun 80 degrees.
the pool STILL does not maintain the temperature it is set for. it maintains around the 75 degree level until i manually press the high speed pump setting, which i must keep doing until it gets up to the desired temperature, which takes hors.
ok, it's probably got a Balboa pack for the controller, but you'd need to look at the label on the control pack itself. If it does say Balboa, then you'll need to take the cover off of the box and get me the 5 digit number off of the white label on the board. From there I can track down the board you'll need.
Well, unfortunately, you can no longer buy just the board for that pack, you have to get the whole control box, which includes the heater as well. To be honest, it will be a much easier installation than doing the board anyway and after checking some pricing, it looks like the whole pack isn't really much more than most circuit boards are. The replacement number for the same pack you have, which by the way, is a Gecko pack, not sure why it says Spa Builders on it, but it's made by Gecko. The part number is
3-72-7079 There are a lot of sites that carry it online, so it would pay to shop around for it, http://www.spacare.com/3-72-7079geckos-classcontrolbox0202-207005.aspx this is just one I pulled up at random. The heater tube will fit exactly back into the same spot your old one is located, so no plumbing modificatoins, but you may need to change or splice the new chords as the plug ins may be different than your current pack. Just let me know if you've got any questions on it or you can hit the Accept button to close out the question. Happy to help out if you still need more info, Thanks, Jeff
