    Jandy LXI heater, shorted h2o sensor

    I was thinking the same thing. It's possible I just didn't notice the burn marks and that could have been the problem to start. I will send the board off to BP.

    Jandy LXI heater, shorted h2o sensor

    Turns out I noticed a burn mark right below the orange chip on the right hand side of the board. When I went to install the new temperature sensor this message was displayed "universal controller, UI FW Rev: 1.8". I am guessing the board did not like having the 10.0k ohm resistor left plugged in.

    Jandy LXI heater, shorted h2o sensor

    Haha. OK, I will give a try again. As a point of reference, when installing the new sensors I did let them "acclimate" to the air temperature for about 10-15 seconds. Once I saw the fault was cleared I installed. I will let it hang for sometime and run the heater as well. Stay tuned.

    Jandy LXI heater, shorted h2o sensor

    Understood, great information.... thank you for explaining. I plugged the 10.0k resistor in, LCD screen reads a constant 75 and the the heater fires as it should. So if I am understanding the diagnosis correctly the board is OK and I got 2 bum sensors??

    Jandy LXI heater, shorted h2o sensor

    I should have the 10k ohm resistor this weekend. It just dawned on me that there is also a 2 part sensor (high limit) on the plumbing on the right side near the rear of the heater. Should I be concerned about this part being bad and causing the fault? Or is the "shorted h2o sensor" fault only...

    Jandy LXI heater, shorted h2o sensor

    OK, I understand. I will source a 10.0K ohm resistor, plug that into the terminal block on the board and hope for 77 degrees. Thanks for your help!

    Jandy LXI heater, shorted h2o sensor

    Many thanks. I am not an electrician so let me double check to make sure I follow. I can plug in a resistor with a value of 9.264 to the lugs on the board, then the reading on the LCD screen should register at 80 degrees?

    Jandy LXI heater, shorted h2o sensor

    Allen, I just switched the heater on and the temperature read 125, immediately the screen flashed to the "shorted h2o sensor" message.

    Jandy LXI heater, shorted h2o sensor

    All wires seem intact. I performed the resistance test on the original sensor (submerged into 85 degree pool water) I took out and got an Ohm reading of 3.41 that reading should have been in the 8.20 range (so I am pretty sure that one is shot), I disconnected the new sensor from the board this...

    Jandy LXI heater, shorted h2o sensor

    Hello everyone, I searched and came up with 1 thread relating to this issue with good advice and followed it. I am now on my second sensor however. The heater is 5 years old and I first got the error message a month ago. I ordered a new sensor and replaced, immediately I got the same fault...

    No flow error on LCD screen

    Turned out to be the sensor. Got one from Amazon. Newer design, easy install. Up and running with no issues.

    No flow error on LCD screen

    Hello everyone. I just noticed the "no flow" message on the LCD screen. I just cleaned the sensor with a scotch brite pad, just cleaned the cell with water and muriatic acid. I hit the reset on the daughterboard and am still getting the message. I also have a add salt message. The computer...

    Pool just opened, preparing to SLAM tomorrow need some guidance

    Installed a new motor yesterday. Thankfully I was able to source one locally. Pool up and running, managed to pass my OCLT too. It is so clear it doesn't even look like there is water in it.

    Pool just opened, preparing to SLAM tomorrow need some guidance

    I thought I was in the clear. The pool looks perfect. My pump motor seized overnight. I pulled the cover off the shaft on the back and tried to rotate it but it was stuck. I will order a new motor and go kit. Any ideas what do in the next few days while it ships?

    Going to test and add bleach before calling it quits for the night. Hopefully I pass the OCLT, pool looks perfect.

    Pool just opened, preparing to SLAM tomorrow need some guidance

    Gotcha. Added a gallon, back to 12. Pool is crystal clear at this point. I will be more diligent with the overnight test tonight.

    Pool just opened, preparing to SLAM tomorrow need some guidance

    Will do, I will bump FC back up to 12. Can I start to add salt to get that level up and how long after adding salt can I test for it?

    Pool just opened, preparing to SLAM tomorrow need some guidance

    I couldn't get to test early this morning so the first test at 8:45 was with sun on the pool for 2.5 hours already. Here are the numbers: FC: 8 CC: 0 Since there are no CCs, does it make sense the FC would drop 3 in 3 hours of sunlight. Meaning this is not an overnight loss of chlorine?

    Pool just opened, preparing to SLAM tomorrow need some guidance

    Marty, Yes, I added enough CYA to get me to 20 via the stocking method. I actually just got finished massaging the last 2 stockings which are nearly empty now. Here are this evening's readings as of 8:15pm. FC: 11.5 CC: 0 PH: 7.4, I also ran the hose from the filter to aerate for 2 more...

    Pool just opened, preparing to SLAM tomorrow need some guidance

    I finally got the PH needle to move. I added a total of 6lbs of Borax and I am at 7.2. Starting SLAM now with 4 gallons of bleach. Here is a picture of what it looks like today, coming along nicely considering there is no chlorine in there.

    Pool just opened, preparing to SLAM tomorrow need some guidance

    OK, thunderstorms here, nothing like being wet AND cold. Got the CYA mostly in, aerated for a few hours. No change to the PH, I just added 2 lbs of Borax. My FC is .5 after adding 2 gallons of 12.5. I had one case (4 bottles left from last year) I used 2 of those so far and have 2 left. I...

    Pool just opened, preparing to SLAM tomorrow need some guidance

    Hello all, The pool was just opened today and it looked remarkably good, picture below. I ran the tests and the results are as follows: FC: 0 CC: not tested, figured I was going to begin SLAM tomorrow PH: 7.0 it could be lower but 7.0 was the lowest panel on the tube TA: 60 - 70, 60 began...

    Air in the pump strainer basket, help please

    I used a shop vac on blower to pressurize the lines in hopes of blowing the clog back out the main drain. That loosened up the clog enough that it came through the filter basket for the main drain. It turned out to be a plastic ring for one of the eyeballs encased in and surrounded by a wad of...

    Air in the pump strainer basket, help please

    I noticed that when I switch the main drain valve to off, the pressure immediately goes back to normal and the filter strainer basket fills back up to the top with only tiny bubbles. This leads me to believe I have an obstruction in the main drain somewhere. Forgive my ignorance but how do I...

    Air in the pump strainer basket, help please

    Hello, I noticed a good amount of air in the pump strainer basket. I have an inground cleaining system with a basket filter located in the pool deck, pictured below. When I turn the system off there was a large amount of gurgling coming from there. Events to note. I tried to swich out my...

    Finally saw the sun for 30 minutes and figured I would see how the TFPC looks

    The pool was closed first week of September. We have a mesh loop lock cover. The pool builder opens and closes for us, I have not taken on this chore yet as we have an infloor cleaning system. I am not sure if this requires any special treatment upon opening or closing. I have been able to...

    Thank you guys. If the sun would stay out long enough I will be in good shape.

    Was finally able to get the cover off this weekend. The pool looks amazing, I can see the Philips head screws on all the fixtures.

    New pool owner... 2nd summer.

    Pool looks nice, good move pushing the fence out to the property line. My only observation and it might be due to the perspective, is the light string seems to be hanging over the pool. I would be cautious if that is the case, not sure how it is wired but it could be messy if it snapped and...

    Swapping out Jandy pressure gauge for glycerin filled pressure gauge

    Thanks again Jim. The link you provided is exactly what I was thinking of configuring. Stay tuned, I am going to grab some plumbing pieces and tinker.
