I'm not familiar with your MasterSpa, but my Coleman, in economy mode, only heats when it filters. And I can start the filtering process simply by turning off the tub at the breaker, then turning it on when I want the filter/heating to occur. I started the tub at 11:00 one night, and now it filters/heats from 11:00PM to 2:00AM every night. When the clocks changed this weekend, it was starting the cycle at midnight, so I just went out at 11:00 last night, and turned the breaker off, then on again.

Ditto Dennis. With all due respect to the original poster, this job doesn't sound like a do-it-yourselfer for you.

Man, you better slow down, you're making me nervous. Remember, you're playing with a force that can kill you. Now, from the main panel of your house, you should have run a 6/3 with ground cable. That would consist of one white (neutral), one black (120), one red (also 120) and a bare copper wire that attaches to the ground. So, in your tub GFCI box, you should have one black, one red, one white and the bare ground wire. You say you only have a black and a white? Where did the red go?

I've NEVER had a false trip. The fact that you're asking leads me to believe that you'll never be comfortable without the GFCI. Do you want to soak, looking at the stars, wondering if you're safe?

When I flip the blanket off, sure, it drips, just like the cover does. Maybe a 1/4 cup of water? A 1/2 cup maybe? I personally haven't experienced any need to continually top up. I suspect that what clings to, and drips from the blanket is no more than what you lose to evaporation without the blanket.

You won't be happy with a cheap blanket. Look at this one from RH Tubs instead: http://www.rhtubs.com/covers/floating.htm I have one and I LOVE it. It is rigid enough to be thrown off and put back on with one hand. I've seen no indication of any ozone damage. On really cold nights, I only open half of the cover, then I just lift a corner and slide in under the blanket. I can run the jets at high speed with the blanket in place - you will not be able to do that with the cheaper bubble wrap blankets.

Okay, now that I know I'm not going to get flamed, I'll 'fess up and admit that I have a blanket, and I love it. I really don't know if it helps hold the heat in the water, but I sure think so. Regarding taking it off, it's cake, because being made of closed-cell foam, it is extremely light, yet fairly rigid. Once I have the cover open with the lift, I can grab the end of the blanket opposite the cover, and with one hand lift it and flip it and drop it right on top of the cover. When I go to put it back on, I just flip it off the cover and drop it on the water. It is so light and rigid, that once it's floating on the water, I can slide it around with one hand to fit it perfectly back in place. When it's cold, I'll open just one half of the cover, then lift the corner of the blanket, and actually slide in and sit under the blanket. It's like tucking yourself into bed.

I'm kind of surprised that with so many posts, no one has yet mentioned using a Spa Blanket, so I'll mention it. Theoretically at least, it seems to me that a combination of insulating the surface of the water from the air space under the cover would at the very least reduce condensation. Of course, that's just my uneducated opinion. I've never tried to mount a refrigerator on to a circuit board. Which, by the way, also sounds (theoretically speaking) like a good idea too.

I strongly agree with Fleece over Terry/Cotton/Velour. I found mine here: http://store.mysticclothing.com/mens-sleepwear/

I know you'll be skeptical, but I have to chime in and recommend Fleece robes. I tried to use my normal heavy, hooded, 100% cotton robe, but when I wrapped myself in that, I felt clammy. The cotton did not absorb the water from my skin. I read another thread somewhere that said Fleece was better. I didn't believe it as I am usually anti-polyester, but I bought a hooded fleece robe to try, and I was shocked by the difference. When I put the fleece robe on to head out to the tub, it really reflects my body heat to warm me. When I exit the Tub, I do towel off, But when I wrap myself in the Fleece robe and pull up the hood, I feel warm and dry. I hate to admit it, but in this application, polyester Fleece, beats Cotton hands down.

I'll muddy the water and go the other way. I had a very basic Jacuzzi Tub at my previous house that sounds like yours. Four jets, everything important below deck. I included that tub with the house when I sold it 6 years ago. Two months ago I bought a used Coleman Tub from a Craig's listing, and I feel like I've died and gone to heaven. Topside controls, multiple jets, actual temperature display, multiple seating positions, ability to heat and pump at the same time, topside filter access, a textured shell that is so much easier to keep clean than my old shiny hard acrylic, the list goes on and on. I can't wait for my nightly soaks.

You could just be seeing the normal behavior of the Spa. The Spa will turn itself on to raise the temperature, then turn itself off when it gets there. Say you set the temperature to 100. When the temperature of the water drops to 98 or 99, the Spa will come on to heat the water back up to 100. When the water temperature reaches 100, the Spa shuts itself off. Is that what you're talking about? Does the Heat indicator light come on during these cycles?

You need a new pc board or the one you have repaired I'm the original poster, I'll answer my own question with what I found, in the spirit of helping others troubleshoot. This was a hung hi speed relay. Look at your relays carefully. One of mine was engaged even when power was off. The contacts welded themselves together from arcing. I pried the contacts apart, aligned them to be parallel to each other - one was a little tipped in such a way as only the top part of the contact contacted the other contact. Then I used contact cleaner, and sanded the contacts. That was tricky - I had to cut little slivers of sand paper, and work the paper back and forth between the contacts with tweezers. After cleaning and sanding and aligning, the tub worked perfectly last night. I also found two of my other relays were not aligned to contact squarely, and finessed those into parallel alignment too.

Hello. I bought a used, "broken" 2001 Coleman Cooperage 104 recently. The "broken" part was just a hung relay. The Spa has worked fine for several weeks now. Anyway, the High speed operation of the motor has become kind of "Flaky". It always starts when the "Jets High" button is pushed. Sometimes it's fine and runs for it's allotted 30 minutes. Sometimes it just stops after a few minutes, and pushing the "jets high" button will not bring it back, but the "jets low" button works. Sometimes while running, it shudders and bucks and spits and then picks right back up again. I discovered last night that when it quits, if I switch to low, low speed works, then switch back to high, high comes back and runs just fine. Another post suggested this might be a thermal problem, but I would guess that if the motor is overheating, low speed would also be locked out until the motor cools. Any help please?
