@CanadianSpaTech I checked the power coming into the board again and it is 240v. There are two lines into the heater and a ground. Each line has 120V, I assume those combined make it 240V to the heater? I went through the doc again and the first page checks pin 3 and pin 1 with the pump off. That reads 118v, when it should read 240v. Then with the pump in low speed, it does get 240v. I checked those same pins in speed 2 and they show 14v. I'm not sure if those are still the same pins I need to check for speed 2 or not though. It does sound like an issue with the board given some of these readings though. I am just west of Denver, CO. I found an electronics repair place that handles a wide range of things so I was going to call them tomorrow to bring it in. https://www.yelp.com/biz/phone-repair-and-more-lakewood-lakewood-2?hrid=37yeX9iTEwfONkv6vCRapA Thanks once again, it would be great to get this repaired rather than replaced.

@CanadianSpaTech Sorry it has taken me so long to get back to this. My spa is hooked up for 240v. I took the readings, for step 7 where it says Pump 1 is not working. On my pump there is a sticker for amps that say 8.0/3.0. In the guide it says pump up to 15 Amp you should get 240v. Mine was reading only 119. I tried other possible pin combination (for the 20 amp location) and still got 120. Not sure if that is correct, but I would assume I should see 240v there. For the heating issue, I saw similar results. It says is should see 240 VAC on line 1 and line 2, but it only shows .038. On line 1 & neutral I was seeing the correct reading of 120 VAC. I'm guessing given the two issues above that don't match up with the readings that are expected, there is something wrong with the board and I should just replace it? Thanks again.

@CanadianSpaTech Thanks for the quick reply and link to the documentation. I'll give these tests a go and let you know where I end up.

@CanadianSpaTech Thank you for the reply. Here are the results from the suggestions you provided: There did not appear to be a schematic on the inside cover. I pulled the circuit board housing out and was able to look at the back of the board but did not see any burn marks. I am unable to pull the board out after removing all the obvious screws and connections. A couple of the edges feel like they are loose, but the board still feels firmly connected where the plugs connect on the front side. Is there anything I can look at on the front side of the board, and do I need to remove it completely? If so, do you have any suggestions for what connections might be holding it in? I removed the filter and left it overnight, but it still remained at 59 degrees and the high speed pump would not turn on. I also checked the power going to the pump and it looked correct. I removed the pump as well, and there were no blockages in the pipes, or in the pump. I have attached just the audio portion of the original video if that helps to determine anything. 818 Brown Squirrel Ln 3.m4a

My hot tub pump works on low speed, maybe not as powerful as it used to be, but when I switch over to high speed it sounds like it tries to start for a second, and makes a click or a thunk sound before cutting out. I can also only get the heat to go to about 60 degrees too. I'm guessing this is related to the high speed pump not working. I have checked all the wiring with a voltmeter, and everything is reading ok. The tub has been filled for a few months, and I ran the cycles to clear any trapped air so I don't think that should be it. Nothing looks to be blocking the flow of the filter either. The breaker never trips, and one thread I found sounded like it could be the capacitor, but that sounds like the low speed wouldn't work, but the high would, which is opposite of my case. I'm thinking I might need to replace the pump, but was hoping someone could confirm that might be the case before I paid the money for a new pump. Thanks for any help in advance. 1619790068_IMG_1401-Trim.MOV
