Hayward T-cell 3 Flow Questions

Today I checked my OmniLogic panel and it read 2800 with a constant flow light. My Hayward Tristar 1.75hp was running at low (25%) as I normally have it.

I bumped it up to full (100%) and it gave me a proper reading (3700, a little high).

My question is, is the T-cell generating at a low speed?

Also, it's 4-5 months old. I got the inspect light the other day. The service contractor that set it up said the 1st 2 times to ignore it and reset it. Any truth to that? Made sense at the time, but after joining TFP I'm learning the industry is severely uneducated.

If it is indicating adequate flow, the SWG should be generating.
Although, the salt reading should not change as a function of the pump speed.
What is the orientation of your cell? If it is horizontal with the hump to the top, there may not be enough flow to clear out gas accumulation and thus getting the lower salt reading. People have have better luck with the cell hump down so that air can't accumulate.

The service light it timer based and will com on every 3 months or so to remind you to inspect the cell for scaling. If you keep the water properly balanced, you will not see any scale or need to clean the cell, so you can just reset the light.

Try putting the cell hump down. At low speed, the cell probably is trapping gas and the plates are not fully covered with water.

just an update, flipped the T-cell and no change.

luckily I have a variable speed pump and found out that it doesn't start generating until 30% (low is 25%).

I also managed to crack a union. I have major over-tightening issues.
Luckily it's not leaking, but I'll have to change it out eventually since it bothers me. I have about 1/4" to work with... but found some cool techniques on YouTube for heating the primer apart.
