Ok, kids... Some follow up... In the final analysis the problem was the PCB board behind the control panel. Fixed for $40. I was feeling pretty frustrated that there was seemingly no means of diagnosing either board without turning around and forking out $350 for a part. Further, had I guessed, I would have guessed the main IQ board so I would have been out more than 5 or 6 hundred bucks after I got everything fixed!! HotSpring seemed to be totally on the ball with a suggestion to call them above ^^^^. However, after finding time in a busy schedule to call them, I just got a run around and looped back to their dealer support network. Zero support, zero help, zero benefit to calling them. Not a bad move on the part of marketing but I feel like this could be done in a more transparent way. Instead, what could have been a shrewd move by marketing and customer service turned me off of their company. What a waste of time... FYI folks, hopefully someone can save a few bucks if this happens to them. For the time being, pm me if someone wants a used IQ board to help diagnose their issues. Say $40 and shipping?

Yeah... That's what I'm thinking too. I called the above number and extension with similar hopes but it seemed to be no more than an effort to route me back to their dealer network. Friendly-ish but not much help. I have a super busy schedule in the upcoming days so I'm hoping my delay will have someone steeped in troubleshooting these pop up here and comment. IF that doesn't happen I'll start pulling things apart and looking for obvious faults on the PCB boards. The control unplugged led is not lit and we do not have an ozone generator... When I unplugged the control panel and resupplied power the control unplugged LED lit up. No joy. Thanks for giving me a few more leads, PS! Cheers!

Well... Received the new thermistors yesterday and installed them straight away. No joy. I can still hear a click when we first power it up (relay)? And it immediately starts flashing the red power light at the control panel. Anyone have any troubleshooting/diagnostic suggestions before I throw more parts at it? Thanks!

When power is switched on the control area clicks and the light starts flashing within a few seconds. The ohm readings were 6.5 and 7 respectively. Is that too big a difference? I'll go ahead and order the thermistors and see if that helps things. Thank you!!

Well, that's close... The power light on the LCD control panel is still flashing. The LCD panel has nothing intelligible displayed on it. The LEDs on the PCB board still read the same way as well... The LIM LED reads "OK", the heater on is OFF, and the control panel LED shows a panel attached. No, it does not. We cannot energize that pump from the main panel or the aux panel. What's the serial number of the spa? It is really difficult to read as it has been largely rubbed off. To the best we can ascertain the S/N is H?4A1?... I think the digit following the H was a Q but it's hard to be certain... That would make my best guess, HQ4A1?... That's my final answer. Yes it does. It appears to be fiberoptically controlled. Thanks for your attention. My daughter LOVES this thing and I'd love to have it up and running for her.

Hello Spa Gurus, You guys are awesome. I love reading forums where the membership is as supportive as yours is; good stuff!! I have what is quickly becoming a "vintage" hot springs hot tub. It has an IQ2000 board and is connected to 110v 20A service. Everything was working fine when we started to get some red blinking light failures. I would unplug the spa, it would reset, and we would be back in business. Recently, my daughter and I cleaned out the filters and put it back together and got another red blinking light. This time, however, the LCD panel would flash all of its icons and then stop displaying anything at all. Now the spa will not heat, I cannot read anything on the display board, but the circ pump stil works. The tattletale LEDs indicate to me that the thermistors are in range, that the main board is NOT calling for heat, and that the LCD control panel is plugged in. I'm not a stranger to electronic repairs but I was hoping for some educated instruction before I started throwing parts at it... FWIW it looks like I need to do the upgraded valve install with the loop built into it... It appears some small amount of water has been leaking in to the control area via the top air valve... Any suggestions, guys? Thanks in advance!
