My SWG keeps error coding to check cell and salt level daily and I don’t know why.

My cell is new, board has been replaced, all under warranty. SWG says I have 3100 ppm salt level. System runs fine with pump running at night when SWG showing 3100 ppm average.

In the morning when I check the SWG, which is now off, salt level average drops to high 1k (ie 1700) and error codes are lit.

I reset the codes and again confirm on SWG display what salt level reading is, which shows low 3k (ie 3100). I reset the average so that 3100 is displayed which allows me
to run that night without issue.

But back in the morning, SWG displays average salt level of 1700 and error codes are lit. I keep having to perform these steps daily to reset my SWG.

What is happening?
 
i see you mentioned it’s an aqua rite 900. Hopefully someone with that cell will see this
 
Two things to check...

Does the Aquarite power off with NO lights when the pump is off?

Check your flow switch for proper operation using a multimeter. I suspect it is stuck closed.

What model pump do you have?

Do you have automation? Not sure what 'auto' means.

Turn off your pump. Are there any lights showing on the Aquarite controller?

AquaRite controller has 3 settings: 1) Off; 2) Auto which means on; 3) Superchlorinate

I leave the SWG set to auto as my pump is on a timer. Once my timer kicks in, pump starts and chlorination starts. Once timer stops pump, error codes appear (check cell and salt level).

My pump is new, no issues with it.

For question #1, once pump turns off via timer, that is when I see error codes and average salt level per controller drops to like 1700, even though it says level is 3200 (for example) in diagnostics.

If my flow switch was closed I would get a flow switch error code which I dont, but I can check. My controller board is new though.
 
The SWCG should be completely powered off when the pump turns off. Sounds like you have a Single Speed pump. Wire the SWCG so that it is on the same timer as the pump.

Your SWG should go into NO FLOW when the pump turns off and not throw error codes. That shows your flow switch is not working.

Show me what a flow switch error code is in an Aquarite. I always like learning something new.

The flow switch should be a secondary safety since it is prone to failure as your has.

The primary safety should be the SWG is not powered when the pump is off.

I will try that thanks

I have wired as per your suggestion and it looks to have addressed the issue, however, another issue has arisen.

Originally, the SWG and pump were on their own breaker (15A each). With the re-wire, both loads are on 1 breaker (15A) now connected to the timer. My breaker seems to be tripping approximately 4-5 hrs after the timer/pump/SWG have been on. This has happened both days since the re-wire.

Is it possible to wire each load on a separate breaker but only use 1 timer to manage both loads?

Yes, it is possible. You may need a different model timer.

What model timer are we discussing?
 
The GE timer can control two independent 120V load following this wiring diagram...

Hot from the pump is switched with NO1 and hot from SWG is switched with NO2.
 
Thank you. My pump (from breaker) has 2 wires and SWG (from breaker) also has 2 wires but when I look at the diagram, I see 6 wires (ie assuming each arrow head is a wire)?

Confirm that your pump and SWG are powered by 120V?
 
Timer wiring.png

  • Red - Timer hot from CB
  • Yellow - Timer neutral
  • Green - Pump black hot from pump CB
  • Blue - Pump black hot to pump
  • Orange - SWG black hot from SWG CB
  • Pink - SWG black hot to SWG
Timer and pump can connect to the same CB.

Neutral connections depend on if GFCI CB is used.
