Taking apart my Aquarite Hayward T-5 Salt Cell to see where it failed and looking for manufacturing flaws for improvement

Single speed pump 25 years old. Rebuilt 2 times. Still kicking ass. Our electricity is not expensive in Pennsylvania. And I have an attic pool heater I put in 24 years ago to heat the pool that requires high speed to get water to the attic. I guess I am in sticker shock at the price of the T-15 cells. I bought my last one on 2016 with a 5 year warranty for 450 bucks.

Thanks for this Beach, I was unaware that the U cover could be removed by hand. The area where the nuts are are definitely a weak link that could cause all kinds of errors and poor operation. I will add that the heat sensor doesn't need to be cut off to gain full access, the power wire can be separated from the U cover.... it has a U shaped flexible cord cover that slides off.

Thanks for the disassembled view. Looking at this I feel like I can reverse engineer some of this to make it work indefinitely. I’ve replaced a few 45k gal cells over the years. If you simply found a resistor to mimic what the temp sensor sees at say 75-85F then you could eliminate that part of the circuit. Replacement generic cells have the job used harness wires blocked and capped at the board connector. Re-water proofing the black and white connections after a thorough dry out should be the ticket as long as the plates are in good condition (chemistry control is prime). I have a few old ones lying around. I guess I need to get to work.

The most common component to fail on these units is the Thermistor that is inside the Cell that is shown in the video. The Thermistor is used to determine the water temp and salt level. If the Thermistor fails, you will more then likely get a "HOT" error on your panel. If you check the Molex connector, pins 6 and 10 connect to the blue and red wires. You can use a multimeter to check the resistance and continuity. The resistance should be around 10K ohm, +- 2K ohm depending on your temp. If you see reading that are way too high or low then your Thermistor is cooked. The easiest fix is to slice the power cord cable sheathing and expose the wires. The blue and red are the ones you need to work on. Cut the wires and solder a 10K ohm resistor between the red and blue wire that are facing the Molex connector. Give the unit a test and the error should be gone. Tape everything backup up with some electrical tape and you are done. The 10K ohm resistor has the control panel think that the water temp is 77F. Fixed my unit this way and it works perfectly. One dollar resistor and 2mins of soldering saved me $1000 for a new unit...

Ned Mandaric Ladies and Gentlemen! I totally am going to do this. You said the Thermistor is used to determine the water temp and salt level only. Does the unit need those readings for anything? My water stays between 55 and 85 year around. But the salt measurment I am worried about, what does the unit need that for and how do I work around it?

Well its not pin 6 or 10 on my female connector but i did find the 2 red and blue wires when i cut the cable open and i do read 8.17k ohms solid so i take the thermistor is good but the panel says its bad.

Thank you for this video and the one where you replaced the Hayward cell. I was wondering about your experience with the aftermarket cell, since this video was published a year after the other, this comment helped understand. I have the same issue with my Hayward salt system. We have had the pool for less than 5 years and we called the guy who installed, he advised it was probably the motherboard. I thought it was a sensor issue with the cell itself, because the cell generated salt when I tested it, and there are no other issues that point to a motherboard issue, but I replaced the PCB (because it was only 150 aftermarket). Did not fix the issue and had been looking at the Salt Pool Store site aftermarket cell but they have several complaints with BBB. This video validates my belief that it was a salt sensor issue all along. Why pay for Hayward if it isn’t going to last? I have the T-Cell 940, which is comparable to a T-15, it’s rated for a higher volume than T-5. The Salt Pool store has it listed for 339 with a 5 year limited warranty, which is a longer warranty than Hayward for less than half the price. Thanks again for the information you have shared!

10k ohm resistor, I took what was mentioned and measured the resistance on the cell plug for the red and blue wires and got around 8.2 k ohms and as a last ditch effort, I carefully sliced and pulled back two inches of the sleeve cut the red and blue and soldered in a 10k resistor. As a result, the system thinks the water temp is 77 degrees. It is actually 84. Prior to this, My cell, T-9 would not hold the instant salt reading and would drop to zero. now, I can take a instant salt reading and lock in 3300 for salt and it doesn't drop. The problem is the plates are probably worn where I get 27 VDC and 2.5 amps draw on the display. It would be cool if I could go further and know if replacing the plates would restore full operation.

@shawnwolf3527 Жыл бұрын

I'm buying a replacement now, and decided to chance it on an open-box Hayward T-15 on Ebay. I've read lots of caution stories about the off-brands, and I was wary of all the high reviews that didn't really mean much under 1 year of use (and when reviews were critical, they talked about failing at 2-13 months, and the lack of warranty support/honoring). It's possible some are good, but I don't see a reputable-seeming alternative system. As long as I have a Hayward controller, it seems it may be best to stick with Hayward cell so I don't have to "game" the system. Some people say salt readings are off, meaning they have to crank up the usage percentage, meaning more overall time on. I've used an undersized cell for the 3 years I've been in my house, and I don't know how long before that it was installed. I've learned from reading reviews that there are different ratings for these different cells. In my case, I had a trickle of chlorine all last year with controller at 100% on-time, then found I had very low salt, added some this year, and still had low production, BUT NO ALGAE. Therefore, my new plan (now that I know how expensive these are) is to 1.) Maintain my pool chemistry, 2.) Keep the cell on for 25-50% of the time. No algae means no need to overdo it, and maximum cell life (amateur assumption, but seems smart enough).

@QuaabQueb 2 жыл бұрын

These things are the biggest pieces of shit. I see them fail constantly, usually only after a couple of years. Salt water pools are the biggest scam in the industry. If it's not the reoccurring cost of the salt cell, or the control panel (which has a common thermistor failure) it will be the eventual cost of replacing ALL of your pool equipment when it rusts away. Hayward makes these systems just cheap enough for them to be sold in mass, this is why they are the most popular and you see them used in most installations. The higher end Pentair, Jandy etc... do not fail as rapidly, but again it's only a matter of time before the salt water eats away at everything, and believe me the swimming pool industry knows this that's why they push this garbage. Fun fact, generating chlorine with a salt water system was actually they way they did it back in the 50's during the boom of swimming pool installations, mostly in California etc... They moved away from this for the exact reason I just mentioned. Salt water destroys EVERYTHING. As chemical manufacturing became more cost effective and readily available it did not make sense to keep chlorinating pools this way. They even had companies that would come to your house and pump chlorine gas in to the pool weekly. (Look up how deadly chlorine gas is, and you can imagine why this fell out of practice. ) Another fun thing is that apparently the metals used to coat the titanium plates (ruthenium oxide or iridium) are mined in Ukraine... well guess what... Ukrainian industry isn't doing so well at the moment so it's going to be a while before you can ever get one of these again. As of summer 2022 the cost for a new salt cell alone ranges from $800 to over $1000
