I have a 45k Capacity Unit, about a year old, after regeneration the water is very salty. I have had a technician come to look at it and he changed the configuration saying it was incorrect. But my problem isn't solved, just $90 lighter.
Hoping to get some answers on here.

Here are some stats.

Grain Capacity = 45
lbs of salt per regen = 15.5
Backwash duration = longer
Brine Refill = post
Hardness = 50

The other specs are the default setting from the instruction manual.

When the regeneration cycles

Backwash = 10min
Brine = 60min
2 Backwash = 10min
Rinse = 6min
Fill =10:13min
