Your dealer will probably say that is a maintenance item.
System info (not programmed)
salt lb/cuft : 7.5 ; A choice ( efficiency vs capacity)
BLFC : 0.25 ; Brine Refill rate GPM
cubic ft resin : 1.5 ; Same as (nominal grains/32,000)
Raw hardness : 24 ; including iron etc
Estimated gal/day ; 120 ; 60 gal per person prediction (auto-tunes)
Est days/regen ; 10.67 ; presuming days each use estimated
Fleck 5810SXT Settings:
DF = Gal ; Units
VT = 5810 ; Valve type
RF = dF2b ; Downflow, Double Backwash
CT = Fd ; Meter Delayed regen trigger
C = 35 ; capacity in 1000 grains
H = 27 ; Hardness grains after comp factor
RS = cr ; Cr = base reserve on recent experience
DO = 30 ; Day Override (typ 30 if no iron/Mn)
RT = 2:00 ; Regen time (default 2 AM)
B1 = 5 ; Backwash 1 (minutes) [3...10]
Bd = 60 ; Brine draw minutes
B2 = 4 ; Backwash 2 (minutes)[3...10]
RR = 6 ; Rapid Rinse minutes
BF = 15 ; Brine fill minutes
FM = t1.2 (usual) ; t1.2 is default flow meter
RE = OFF ; Relay
VR = OFF ; ?
The less salt per cubic ft, the more salt efficient, but more hardness breakthrough.

I sincerely hope they don’t try to pull that sh1t.
On my original purchase paperwork it says “5 year warranty on Fleck 5810SXT”
So I mean...any more than $70 if they wanna charge..I’ll just buy the parts myself! (Hell I already had it apart alresdy!)
EDIT:
This may be a dumb question..but where is the best/quickest place to get a new piston kit?
I looked on Amazon and didn’t see anything for the 5810..
