  1. So I installed both the temp sensor and the high limit sensor yesterday and it worked fine for about 9 hours and then things stop working right. The temp stays where it is and the heater continues to call for heat and the pump never shuts off. I woke up this morning and power cycled the tub and it shut the pump/heater off for about 5 minutes and then it kicked back in. Then continue to run never kicking back out. The saga continues.
  2. Sensors on order, awaiting delivery. thanks guys
  3. Can you explain why you think it’s a flow issue if it fails with the high limit back on the tube? I’m not doubting just trying to reason this out. I’m just grasping for answers in my own head which haven’t been right so far. You are right, having the panel off does not affect how the tub heats. The tub water was still heating to 104 and shutting off. The high limit probe was installed by the factory against the outside wall of the heater tube under a piece of foam. When the access panel is taken off its exposed to outside air which shows a lower value. The Wi-Fi probe that I put in is in the exact same spot so when the panel is off the values are lower but show the on and off of the heater in the previous pic. The tub water was actually still 104 but the reading on the outside of the heater tube was not having outside air exposed to the high limit probe i appreciate your patience with me.
  4. So I put a Wi-Fi thermometer on the heater tub 36 hours ago when I took the high limit probe out and let it sit outside. For those 12 hours the tub didn’t heat properly. Yesterday around dinner time I shut down the tub to check something and turned it back on. As you can see in the photo it’s worked flawlessly for the last 24 hours. Yesterday in a frustrated state I forgot to put a back access panel back on which is why the peaks are so much lower until this morning when it was put back on. Not feeling like messing with it tonight I placed the high limit probe back on the heater tube. If it messes up again tonight I know it’s the high limit probe. I’ll check the resistance in both sensors tomorrow to confirm. Man I hope this is it, it’s been a fight for while now.
  5. I will try that out today then with them in place. I didn't know if it would alter things enough with the high temp sensor compressed on the heater tube and the temp probe actually in the water. And yes it us a gecko M class. The heater tube is not in the spa pack, it is separated and a foot away. The high temp probe is a 48" cable that travels out of the spa pack and over to the heater in the next access panel. I left before sunrise today but will get pics when I get home.
  6. A new set of sensors is tough to swallow on a hope but I think that's my next step. I appreciate your advice. I never thought to actually call the manufacturer, good call. Thanks!
  7. It is spray foamed in and I haven't taken it out to inspect but at this point I'm assuming it hasn't moved I've had the filter out for the last 2 weeks...no change Oh yeah that was found in the impeller on the old pump, nothing to worry about now The new heater element was installed on January 17th as the old one was causing a short tripping the GFCI, Water was leaking by a post in the heater tube.

  8. This I didn't do. The temp probe is spray foamed into the shell and didn't want to remove it yet to compare the 2 in the same air temp. My meter died before getting a chance to test the high temp probe so I didn't get a reading off of that. You'll cringe at this but I hung the high temp probe out of the cabinet and ran the tub to see if that was some how cutting off the heater with no error code, didn't help. I did, it was about a degree difference
  9. You’re right that it didn’t magically stop there but at the southern Ontario temps we’ve been having (-5°C to -10°) that’s about where it was sitting for the last week. If I turned the set point to 99° the heater would shut off and the pump would shut down but turn it back to 100° or above and it would just run continuously and not warm any further unless I put it on high speed. The temp probe was 6290 ohms at 97°. I’ll get pics of the equipment in the morning thanks for your reply
  10. I have a 2009 Arctic Spa hot tub and I’m having hard time getting it to heat to 104°. I’ve had several issues over the winter which caused replacement of the pump with impeller, heater, cover and pressure switch. On low the heater kicks in (amps are 23 and volts at 240) but the problem is the tub never really heats past 100°. If I turn the pump on high and continually turn it back to high I can get it to 104° but settles back down around 100. This causes the pump the run continuously on low because the temp set point is never reached. I had tested the temp probe and high limit probe for resistance and both were closing to normal readings. The only thing I know is broken is the bypass valve in the bottom of the filter canister. Could this being broken cause low enough circulation that the tub doesn’t adequately heat on low? edit: also no error codes
