The breakers, wiring, subpanel, etc. are brand new, just installed about a week ago (wrong the first time with only 3 wiress), electrician came back today, put the right breakers in and the right amount of wires, but it either isn't heating or it isn't heating very well. As soon as power was back to the spa the temperature was 84, 4 hours later it is only 86. There are 2 lights lit on the main control board, a green and a red but they aren't flashing. Also, if we set the temperature below 86, the heater light on the control board turns off and we hear the heater click off. When we turn the temperature up past 86, we hear a click and the red light goes back on. The odd thing is that the heater was working after the new circ pump was put in, it heated the water about 10 degrees in 2 hours, but as I mentioned above, it blew the breaker. I keep reading about resetting it, but I can't find a reset button on it. We have a message into the technician again, but were hoping to figure it out in the meantime. He already took off the heater relay board and it seemed ok, nothing fried on the back of it. I'm not sure if this is important or not, but when the temperature is set to 86 (the current temperature) the ready light on the main panel is green. I'm wondering if we could still have a blockage as I don't see any bubbles coming out of the drain, although it feels like there is a bit of warm water coming out of the drain. Is there something else I can do to try reset the heater or thermistors, or something? Thanks again.

Thanks for the additional info...we had the technician come back and he determined that although the pump was running, it wasn't running well so he installed a new pump. We started to see movement out of the drain and this time it didn't trip the high limit thermostat. We left for about 2 hours to let it heat up, but when we came back, there was no power, it tripped the breaker in the sub panel. We reset the breaker 3 times and it shut off immediately, then on the 4th reset, it started working again. It's now been back on for about 2 hours and it still seems to be working. I guess the test is to wait until morning to see if it reaches the set temperature and maintains it without tripping the breaker...if it trips again I'll have to figure out what else could be wrong with it! Thanks again!

I have started a new thread, so I apologize if I have duplicated what I have said in other threads, but here is the problem: After turning on the breakers at the sub-panel, with or without jets running, the unit shuts down and the ready light flashes on the main display panel. This happens with and without filters. The breaker doesn't trip, but the only way to restart the spa is to turn the breaker off and back on again. There is a slight hum coming from the circ pump. I dont' know if this is normal, but a small stream of water shoots back into the filter compartment, so I'm not sure if this is from the ozonator or an overflow of the circ pump. We had a technician look at it (when it was wired wrong) but he couldn't figure out why it wouldn't heat. He thought it was wired wrong but my husband kept insisting that there are only supposed to be 3 wires hooked up, so that didn't help the technician (especially since my husband was wrong). Without the heater hooked up, the jets run fine and everything seems to be working (except the heater, since it wasn't wired). I don't know if you can normally see water coming out of the heater return/drain, but we don't see anything, and as mentioned before, the only movement we can see is in the filter compartment (even when jets aren't running). We have hard water, and based on what was mentioned in another thread, the sizzling in the heater sounds like there is little or no flow. This is what the technician did: Took off one end of the pump to see if there was an air lock, none, then checked the opposite end of the heater for an air lock, and again none. He opened both drains, nothing there either. He checked the suction where the grey standpipe is, and there is suction there, so does that mean the pump is working? Also, he checked the voltage of the heater (none because it was wired wrong), and he also took off the heater relay board to see if anything was fried behind it. We also put a plastic bag over the drain but nothing, so my guess is a blockage. I will call him back, to check the suggestions made by PreservedSwine, but wonder if there's something that I can do in the meantime. Note that after he left, I put a garden hose down the grey standpipe in case there was an air lock somewhere else and nothing happened, the spa still shuts off after about 30 seconds. Thanks.

Thanks for the reply. I just saw your reply to that post today. For some reason, I thought that I would have received an email indicating that someone replied to my email. My apologies...it must have been another forum where I mentioned the same problem. I will start a new thread and start from there... In reply to your post above, what threw him off was the fact that it wasn't wired right, and when it was wired without the heater hooked up, we didn't have this problem. Now that it is wired correctly, I want to find out what is wrong with it before calling him (or another technician) back. Thank you for all of your suggestions...Starting new thread now...

Just saw this...didn't think anyone replied! This issue was fixed but still have a problem with something tripping out on the board (as per my piggy backed post you saw earlier)...

I actually did start my own thread but no one replied to it, then I came across this thread, and this is the exact same problem I am having. From his original post, it didn't trip the GFCI breaker at the sub-panel, just stopped everything from working, jets, light, display, heater, etc. I believe this pump and heater were already replaced a few years ago. We had a technician look at it, he checked for air locks at the pump, heater, drains, but couldnt' find one. We did remove the filters, and the pump is humming so there is some water flow, maybe not enough. At this point, it could be many things and I'm open to suggestions to narrowing it down. Thanks.

Hi Laird: I don't know if you still receive emails, but wondered what you did to fix the problem. I also have a 2002 Grandee GC (Canadian model) and the exact same thing keeps happening...breaker doesn't trip in the sub panel but something trips out on the circuit board somewhere, no jets work, light doesn't work, display goes dead, but ready light flashes. We had it hooked up wrong originally because the electrician only hooked up the 20 amp and was confused by the 30 amp, so when the heater wasn't hooked up, there were no issues. Jets would run, nothing would trip, but the tub wouldn't heat (obviously because the heater didn't have power). Now that the heater has power, we hear a sizzling sound, part of the heater gets so hot then after about 30 seconds everything goes dead. I think it might be low flow out of the circulation pump, but the technician took off the hoses to make sure there wasn't an air lock. Unless the pump isn't working at all, and the buzz is coming from the ozonater? I don't know if this makes a difference or not, but there is a stream of water that pours back into the filter compartment, maybe this is back flow? Anyway, I hope someone still monitors this thread because I don't know what to do to fix the tub and I don't want to start replacing every part to find out it's something simple. Thanks.

Hi everyone: We just moved a hot tub, ran new wires, filled it up and thought it was working fine, until it didn't heat up. I have been reading posts online about what to do and I am completely lost. One thread I read says to press the red reset button on the heater but I can't find one. Also, the electrician isn't completely sure if it's hooked up correctly because what is in the panel doesn't exactly match what's in the manual and the cover of the panel is a little confusing. All jets as well as the light work. There are also lights on the circuit board. The power light is green and the heater light is red (nothing is flashing). We cleaned the filters, the weir gate is working fine, and the circulation pump seems to be working as there is a slight vibration on it and on the heater. The water just doesn't seem to be moving around in the tub. When it first had power, some cloudy water poured out of the drain and it seemed to be circulating. What can I try to narrow down what the problem is? I have a picture but don't know how to paste it on here. If this helps, there are 3 wires coming out of the deck, black wire is hot and is in #2, red wire is hot and is in #4, and blue wire is neutral and is in #5...is this right? Note that this spa is in Canada so I think the wire colours are slightly different for hot and neutral. I am extremely clueless when it comes to this spa so I would really appreciate anyone's help!! Thank you.
