Hayward Swim Pure Salt Issue

[Philo]

I've run into a neighbor's Hayward Swim Pure with a Hayward t-15 cell that flashes "check salt" daily. The display shows 2000. Instant salt reading is 3200. Taylor K1766 says 3000.

I scroll to the instant salt reading (3200) and then to "super chlorinate" and back to "auto". The average display now shows 3200 and the "check salt" goes out.........until the next day. Then it's the same routine. The cell is 1 year old.

What's up?

The cell might be running with no flow.

Is the box powered when the pump is off?

Does the no flow show when the pump turns off?

What are the diagnostic readings?

I replaced the flow switch just to be sure and the "flow light" is off.
Taylor Salt today is 3200
There is an intermatic timer and it's synced to the VS pump.
Everyday the "inspect cell" and "check salt" light are flashing. The "power" and "generating" green lights are solid on.

Looks like the cell is going bad.

Did you check the cell for scale?

What are the first 7 characters of the cell serial number?

 

[Philo]

The Cell is clean.
I put it in for them on 7-1-2018
Serial #'s 3E17349

The cell has a 3 year warranty. I would suggest a warranty claim.

Thanks James!

If the flow is low and the cell is installed upright (with the larger side on top) then they say the plates will not be sufficiently covered. Among other things this could lead to a "low salt" reading, which is computed based on the observed current flow. New guidance is that the cell be installed "upside down" if a variable-speed pump is in use.
