  1. I pulled the circ pump filter this past Monday, and the "moto-massage" instantly started working dramatically better, so that is pretty compelling! Also, I cranked up the heat to 102 and ran both jet pumps for over 30 min, and no shut down. :-) I didn't expect that was going to work, since I had just cleaned the filters a few weeks ago. On the other hand, I can't remember when I replaced this filter last. (we use a paper filter on the circ pump) I will be buying a new filter this weekend. I'm pretty convinced that is it, especially given the moto-massage, but I'll report back in a month or two. Thanks so much! n8
  2. Is there a good way to narrow it down between the circ pump vs. the plumbing? The unit is coming up on 8 years - is it typical for the pump to start failing? Would that be consistent with the fact that it fails every time with everything running but has only shutdown once (in over 6 months) when the tub was not in use? Thanks for the guidance! n8
  3. Just made it happen, and checked the lights: both of them are OFF after this occurs. (only took a few minutes after running everything including the heat up to 102) I know the "LIM OK" was ON and "Control Unplugged" was OFF yesterday while I was waiting for it to happen. Does that imply my hi-limit thermistor is bad still/again, or are there other reasons for LIM OK to go out? Thanks, n8
  4. OK, next time it happens, I will open it up and have a look. Speaking of that, I opened it up yesterday, and put a video camera on the main board, to see if I could see anything unusual when it happens. After well over an hour, it hadn't happened. This is the 2nd time for this experiment with the same no-fail result. That makes me wonder if I have a heat issue. The AC/DC converter was quite hot, but I imagine that could be normal. Thanks for the reply! n8
  5. sorry about the formatting - not sure why all of my CR/LFs were stripped?! n8
  6. Greetings, we have been struggling with this issue since last Sep. It has happened every time we use it, for a total of about 10-12 times. The symptoms: ------------ The jets go out first, about 30 seconds later the interior light goes out, and then about five seconds later the control panel goes dark. i.e. seems like a very purposeful shutdown process The control panel then goes to a flashing red power light and nothing else is on or works. Actually, the blue light over the control panel continues to work. The circulation pump (bubbles) also continues to work. Sometimes it takes several hours to happen, but sometimes <10 minutes. Most of the times, I have been in the tub, with the lights on & the jets running. Yesterday, it happened with the hot tub closed up for the first time. (hasn't been used in a week) Can't say for sure, but increasing the water temperature (to force the heaters on) seems to exacerbate the problem. Toggling the 30 amp breaker for jet pumps will remedy the problem temporarily. Tried / Tested / verified: ------------------------- Had the heater/control board replaced. (Oct) Had the hi-limit thermistor replaced. (Nov) Waxed filter compartment door with a candle. Connections to control board are solid. Today I put a video camera on the filter compartment door, turned on the lights, all the jets, and cranked up the heat. Reviewed the video to confirm filter compartment door was open and water was flowing well at time of shutoff. Cleaned all the filters. Any other suggestions? Thanks, n8
