I recently moved in to a new house with a pool. It was previously running 4 hours a day on high. I wanted to change that to 1 hour high (for the navigator pro cleaner to clean) and 6 hours on low to save energy and money with the side effect of less bugs and organic debris floating on top. So i decided to change the timing from 10am to 2pm on high to 10am to 11 am on high and have it run from 11am to 5pm on low. I also changed the salt cell from 35% to 20%. When i did this i forgot about am pm so i accidentally switched the am pm timing on the low speed. I noticed this when i was listening for the pump to switch speeds at 11. It just shut off. So i walked out to see why i figured it out and fixed it. When i left the timing page it turned on to high. Then after the three minutes of start up it switched to low for about 15 seconds then stopped then about two minutes later it started back up again just to stop again. And this cycle repeated about five for six times until i switched the timing back.

Note: the salt cell earlier this week had dropped around a thousand ppm and has slowly came back up to 2600 ppm and gone up and down a 100 ppm over a day or two. So i am assuming it needs to be cleaned but just haven't go to it as with all of the new house cleaning and stuff like that.
 
:wave: Welcome to TFP!!!

That behavior is odd, I have not seen that with mine.
For me, if the pump is off, push the Filter button once and that will turn the pump on high. Push it again and it will switch to low speed (after a few minute delay). It should then stay on low until the Low Timer turns off. I am not aware of a way to have the pump turn on directly into low speed.

I would verify that the wiring for the 2 speeds is correct in the controller and the controller knows that the 2nd relay is for low speed and that you have a 2-speed pump. Some of that must be true for you to even have the option to set the Low speed timer.

Do you have an independant way to test the salt? That is highly recommended to you can verify trends in the SWG reading.
You can inspect the cell for scaling, but if nothing is visible, I am not sure I would clean it as that shortens the life.
 
Ok if i press the filter button it will go into low speed operation. It will also then shut off after the 15 seconds.
as far as i can tell it is correctly wired and is configured for two speed operation and yes the second relay is for the low speed and when i press it it reads something like low speed filtration inactive.
As for the SWG reading i have test strips and those read out 3300 ppm the same as the SWG did before it dropped off.
 
I have not see a message like that before and do not see anything in the manual.

So each time you switch to low speed, it turns off and then back on again and keeps cycling?

You might need to contant Hayward CS as I am not sure what that could be. If you do call them and get an answer, please report back.
 
Just a quick thought could it be that the pool wasn't priming on low speed and so it was auto shutting off. I do have a slight slight leak in the pump lid when running like one or two water drips that's it. There was also air in the pump a little more than usual but did not think of it at the time.
 
Ok so i believe that i have a air leak in the suction side of the system, cause we have bubbles coming out from one of our eyeball return ports. (I believe that is is in the pump lid) Could it be possible that it holds its prime at high speed despite the large air bubble in it but would lose prime in low speed?
 
Ok i was just back there for an hour with my computer going over all of the wiring im am going to include some photos for you to see but unless it is wired differently at the pump i have no clue. And i double checked the configuration in it and it is all correct according to the instalation manual. So i might just have to call a dealer and see what they can do via warranty and stuff like that. Unfortunately this pool is quite old so i would guess it is not under warranty anymore. Also it is not the pump not priming i managed to get the lid open and refill it so it is full of water and no big bubbles. And it ran fine.
Note: if you look closely the pump wiring goes down two different pvc piping do they link up somewhere underground cause there is only one pvc pipe connected to the pump via the thick gray cable cluster thing.

There should be 4 wires that go inside the pump. You would have the common wire go to one terminal, the high-speed hot to another terminal, the low speed hot to another terminal. And there would also be a ground wire to the green terminal.
There should also be a bare copper wire coming out of the ground that attaches to the outside of the pump which is your bonding wire.
