If you can't test the sensors yourself take them into your local hardware store and ask them to test them for you. I'm sure they will know how to work a multi meter for testing. Rd is saying replace the entire spa pack...New board. heater, sensors I see what do the sensors look like? Quote Link to comment Share on other sites More sharing options...
CanadianSpaTech Posted March 31, 2020 Report Share Posted March 31, 2020 Along the chrome heater tube at the bottom of the pack there are 2 black nuts with a grey wire coming out. One at each end of the heater tube. They attach to the circuit board on the lower right hand side of the circuit board. There are small tabs that need to be pressed down to release them from the board. https://www.hottubworks.com/blog/testing-sensors/ You may want to call for service at this point. They will have extra sensors to use for testing and give you an answer before you start spending money on something you don't need. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted March 31, 2020 Report Share Posted March 31, 2020 Given the burned heater terminal, which probably means bad heater, and this other as yet unknown problem, I think a new pack is a good choice. I can't find that board to see what you've got. It is 120v, one 2 speed pump, no circulation pump, 3 kw heater? Quote Link to comment Share on other sites More sharing options...

Ok thanks ive managed to get the sensors out and looking online they are only about 30 pounds for the pair. which i can get its just the board its self, could i get a second hand one from somewhere? 120v, 2 speed pump, no circulation pump, 3 kw heater Quote Link to comment Share on other sites More sharing options...
robbieboy Posted April 1, 2020 Author Report Share Posted April 1, 2020 Just a quick update i called a hot tub place and they said its likely the board is ok and if it wasnt there wouldnt be anything on the display at all. So i have ordered some sensors, if it isnt the sensors they said i can send them back and get a refund at least Quote Link to comment Share on other sites More sharing options...

robbieboy Posted April 3, 2020 Author Report Share Posted April 3, 2020 Hi guys so the update is the new sensors came today, I replaced the old ones and it worked and it fired up like it used to for about 10 mins then I was back to square one. same reading on the display I'm assuming ive nowruined those sensors as well some how. so i was going to send them back and say they didnt do the job. bit naughty but they cost 60 pounds Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted April 3, 2020 Report Share Posted April 3, 2020 I seriously doubt you ruined the sensors, they simply did not solve your issue. In 25 years, I have never ruined a sensor by plugging it in. It is curious that it ran for ten minutes. Was the display normal? Did the temp reading go up? Was it in standard mode? Reset the breaker and see if it works again. Leave it off for 30 seconds or so. While the old sensors are out, take a resistance (ohm) reading on each of them. They should be fairly close, within a few hundred ohms. If so, they are good. Test the new ones before returning so you can feel better about returning them.

CanadianSpaTech Posted April 3, 2020 Report Share Posted April 3, 2020 So it's not the sensors so now i think it's time to replace the pack or call for service at the very least. Can't think of anything else we can do from here. Quote Link to comment Share on other sites More sharing options...
RDspaguy Posted April 4, 2020 Report Share Posted April 4, 2020 I think it a good idea given all the issues. If you wouldn't mind, for informational purposes, could you unplug the topside control and turn it on? See if it comes on after a minute. Tomorrow I will make a call to a buddy of mine also in the business and get his thoughts. Maybe he has run into this before. Quote Link to comment Share on other sites More sharing options...

Hi spaguy I was wondering if you phoned your buddy for me as i am now at a stand still and me thinking the new sensors done the trick i threw out the old sensors so im alrady 60 pounds down. do you think it needs a new heater? as the board, pump and topside display all seem to working ok.

RDspaguy Posted April 6, 2020 Report Share Posted April 6, 2020 I did, he has not run into this before either. I thought your topside was still showing dashes. Is it working now? I seem to recall seeing a burn at the heater terminal on that board. And corroded heater element terminal. Try unplugging the topside from the circuit board and see if it starts automated functions. It will take it a few minutes to turn on with the topside unplugged. Quote Link to comment Share on other sites More sharing options...

Hi spa guy yeah the topside is showing the same dashes but that is functional as i have bought a new topside display recently and i have the same dashes. I have tried also to fire it up with out the display plugged in and no joy. yeah one of the copper strips connecting to the heater. do u think it could be a bad heater?

RDspaguy Posted April 7, 2020 Report Share Posted April 7, 2020 Not causing your problem. But I do think both heater and board are bad. If the topside is known good, it must be the board. I would get the new pack. More bang for your buck and new pack warranty. Quote Link to comment Share on other sites More sharing options...

robbieboy Posted April 8, 2020 Author Report Share Posted April 8, 2020 lol any go to guy will do. so this morning i come downstairs and the electric was off so the hot tub trip out at the switch board. I tried switching it back on and there was a "boom" at the board so i think ive now blown the fuse. Is that confirmation the board is bad.
