Makes sense. Thanks, Jim. The reason for my question stems from some erratic behavior from my SWCG cell display lights & miscommunication with the EasyTouch panel (as indicated in another post). From what I can gather, these cells have a life expectancy. Some people feel that problems can arise...

This is just a curious question. I noticed that ads for the Pentair IC20 SWCG include a so-called power center. Since my SWCG plugs into a Pentair EasyTouch control panel, is the power center for the SWCG inside of the EasyTouch? Thank you.

Jim: Thank you for the response. The "railroad crossing flashing red & green light" continued long after the power-up sequence. As I mentioned, the filters were cleaned recently. So I am confident that dirty filters are not the issue. I also removed & inspected the SWCG. It looked clean with no...

JoyfulNoise: Thank you for the link. I will spend some time to absorb the info.

I have a Pentair IC20 SWCG. During the past month, the readout on my EasyTouch control panel indicated "0 ppm" of salt. However, my test kit showed a salt level of 3,400 ppm. By rebooting the system, the SWCG apparently starting "talking" with the EasyTouch & indicated the proper salt level...

Thank you.

After the lights scroll, the following lights light up: salt level low light is red; cold water light is red; and cell light is green. When the More button is pressed & released again: the salt level good light is green; the cell light is green; and the flow light is green.

Thank you for informative videos. Forgive me if I missed something, but is there a definitive way to test whether the thermistor is faulty? Thank you so much!

Thank you, JamesW. Where is the thermistor located? Is it part of the SWCG itself? I ask this because the water temperature readout on the EasyTouch panel seems to be accurate. The date on the bottom of the cell is "11/24/2015".

The salt level light is red. Both the flow light & the output light are both steady green. The cell light was off. As previously done, I rebooted the system. The cell light was green for a few seconds, then switch off (as Jim mentioned). However, the salt level light is now a steady green...

Again I noticed that the EasyTouch control panel is indicating "0 ppm" for the salt level & the light on the SWCG is a steady red. As before, I will reboot the system again which previously got the EasyTouch & the SWCG to "talk with each other". But my question is this: Assuming that the SWCG...

Jim, Thank you so much for the thorough response. I shut down the power & rebooted the system. Voila! All is good with the world again! If in the future this becomes a chronic issue, I really don't have a problem with the EasyTouch control panel not "talking" with the SWCG as long as the SWCG...

My Pentair IC20 SWCG is connected to a Pentair Easy Touch control panel. I noticed that the readout on the SWCG indicated a low salt level. The diagnostic info in the control panel showed "0 PPM". Didn't seem right since the salt level aways ranges from 2,800 - 3,400 ppm. So I checked the salt...

Was the recommendation of a pool builder. Actually, a pressure test & bucket test suggest no evidence of a leak. However, salt level results (both the readout from the SWG & a separate reagent test) indicated a falling salt level. Placing skeptical reliance on the readout from the SWG, I...

Due to a concern that the salt level in my in-ground spa might be decreasing (possible leak or inaccurate testing?), I was advised to monitor the salt level with the heater off for one month. I am curious about this recommendation. What effect might maintaining a heated spa have on the salt...

No. The auto cover seals off the spa quite well, in addition to the perimeter coping which slopes away from the spa. Keep in mind that we have had virtually no rain during the past 3 months. If the water level were to rise above 2 - 3" (I would guess), the excess would spill over into the...

Matt, Thank you for your response. I plan to refill my spa in a day or two. Once I get the salt level & my water chemistry back in balance, I will follow your suggestion & test 40ml of water with the K-1766 every few days (rather than the 10 ml I tested in the past). I will ignore the IC...

In spite of the bucket test, 2 pressure tests & a 30-day monitoring of the water level, my spa builder insists that adding approximately 10 lbs. of salt to a 2,500-gallon spa every 5-6 months in normal. I am hard-pressed to understand his reasoning. (BTW, I am awaiting his follow-up response). I...

Sorry for being redundant, Mark. Since I am getting conflicting information from various sources, I'm having difficulty sorting out my problem. Not personally having expertise in this area, I sometimes feel like I am being batted back & forth like a ping-pong ball.

Just a follow-up on my last post. Having likely ruled out the possibility of a leak (as a result of the bucket test & pressure test), my spa builder said that adding 10 lbs. of salt maybe every 5-6 months was normal. Is there any validity to this statement? And if so, why? Also, in my above...

Good point. I count the last drop that turns the solution from a milky cream color to a dull, reddish brown. I have heard that comment regarding the SWG readout on this forum. That might explain why I might have been unnecessarily adding salt. Thank you.

Thank you, Mark, for the explanation. In fact, one of the possibilities I am looking into is the accuracy of the readout on the EasyTouch control panel. I spoke with one of the techs at PentAir & advised him that at times the readout indicated daily fluctuations of 600 - 1000 ppm. He felt that...

Mark: You are correct about the redundancy of the pressure test. Since the spa is new & under warranty, I wanted to be absolutely positive about the results of the bucket test. Maybe it was for my peace of mind. Forgive my ignorance, but could you please clarify your statement that "However...

Good point. However, with the auto fill off, I did the "bucket test" which indicated no leak. So here is where I am at: 1. With the spa pressurized at 10 psi for 48 hours, the pressure held constant. 2. There is virtually no splash out. 3. With the auto fill off, the bucket test indicated...

Matt: The pump runs 4 hours daily for filtration & chlorine generation. The set temperature is 81F. Prior to use, I will ramp up the temperature to 98F. The white film that I noticed is not evident along the waterline.; but rather on the bench which is always below water. As I previously...

Maybe I am misusing the term "scaling". This is not a hard deposit line along the waterline. I am referring to a thin whitish film on the horizontal 1" tile on the spa bench, as well as the tile that is underwater in the skimmer cavity. Might this be the result of too much salt? I am diligent...

After draining our in-ground spa (to pressure test for a possible leak), I noticed some white scaling on the tile surfaces. Although the deposits were easily removed with a ScotchBrite pad, the spa builder said that this was likely due to either too high of a salt level or a calcium issue...

Kelly: Indeed, I have noticed the same with both the readout from the SWG & the Taylor reagent test kit. In fact, I have seen daily swings of up to 1,000ppm. In spite of this, there seems to be a downward trend in the salt level. Most perplexing. If anyone might have any other thoughts, I...

Re: Pressure Testing Advice The spa has been pressurized for the past 6 hours & the pressure is holding at the benchmark level of 10 psi. If the pressure holds for the remainder of the test period, I am perplexed as to why the salt level has been falling (see my post directly above). Splash...

Pressure Testing Advice I have a suspicion that I might have a small underground leak in my in-ground spa. During the past 40 days, the water level fell a total of 2" with a half hour of use daily & the auto cover in place the remainder of the time. I have been told that this is quite normal...
