" hot " showing on aquabrite display for 3 weeks now

The power supply looks ok.

The problem is with the cell or maybe the salt test.

Try a different salt test.

I would change the cell type to T-9.

Ok, will do. I think the salt test is OK, as I added a bag and it went up to where I would expect ( my pool is usually 500ppm per bag). However, a new bottle of reagent came yesterday, so will test with that.

I will try setting the cell to T9. I have it at t15, because when I first used this type of cell, it did not work when set to what it is - T9, and setting to T15 fixed it.

thx

Ok, this is odd:
It was generating OK when I just looked, out of nowhere, however it is at 2900.
Did salt tests with new reagent and it is at 3600 ( which explains the rise to 2900 on the display, thus why it is generating as over min threshold).

tired to set salt, still same issue when set to T15 ( countdown starting too low).

Switched it to T9, and have an opposite issue: it counts down from 5400, but stops at 4000 - will not go to the 3600 I need.

Any thoughts on next steps?

cheers !

Leave it on T-9 and it should work fine except that the salinity will be wrong, which does not really matter.

Most likely, the cell is underperforming due to some defect in the cell.

OK, thanks ! I will see if I can get another new cell. Could the issue I might face, be when salinity is good ( say 3200), but SWG thinks it is at 2600 or below, it will then stop generating, right ? thx

It stops below 2,400 ppm.

A T-9 setting makes it read about 1.5 times too high, so it will continue to produce.

For example, if the T-15 reading was 2,300 ppm, the system would shut off.

With the T-9 setting, the reading would be about 3,450 ppm and the system would continue to produce.

OK, thanks. So the main downside is not actually knowing what the salt level is from the display ? So I will either have to manual test regularly, or more likely , forget and get algae lol ?

Hayward salt level display is always unreliable and you should always manually test.

As long as the reading is over 2,400 ppm and the current is below 8 amps, the system will work.

You can test manually and you can divide the reading by 1.5 to get the actual.

You can divide the reading by the actual to get the multiplier.

stops at 4000 - will not go to the 3600 I need

4,000/3,600 = 1.11.

So, divide the reading by 1.11 to get the actual.

 

[JamesW]

As long as the reading is over 2,400 ppm

Assuming a multiplier of 1.11, the actual can go as low as about 2,200 ppm before the system would shut off.

Yes, I am sure they have all the caveats. However, it has always been within 200 for me, which is fine.

This is very helpful, as I can still use the display as a quick reference, thx !

Any idea what is the actual cause of it doing this, seeing as it has been fine the last 12 years I have been looking after it. thx !
