Most 5600SXT softeners have a 0.5 gpm BLFC. You could check, because you could be an exception.
You have presumably been using a lot of salt. So if you are not getting softening, check to make sure that your bypass valve is not in the bypass condition. Otherwise lack of softness is not a setting problem for you. If you are not getting soft water, I suspect you have a hardware problem. Do you know how often you regenerate? How old is your system?
How much water is in the brine tank, and does it get sucked out during the BD cycle? That is worth checking. It should get sucked out about 15 minutes into the BD cycle.
Until you get your hardness kit, I suggest these:
System info (not programmed)
salt lb/cuft = 8 ; A choice ( efficiency vs capacity)
BLFC = 0.5 ; Brine Refill rate GPM
cubic ft resin = 1.5 ; ft3 resin = (nominal grains)/32,000
Compensated hardness = 16 ; including any compensation
People = 2 ; gallons affects calculation for the RC setting
Estimated gal/day = 120 ; 60 gal per person typical calc
Estimated days/regen = 18.75 ; Computed days including reserve
Fleck 5600SXT Settings:
DF = Gal ; Units
VT = dF1b ; Downflw/, Single Backwash, black cam
CT = Fd ; Meter Delayed regen trigger
NT = 1 ; Number of tanks
C = 36.0 ; capacity in 1000 grains
H = 16 ; Hardness-- compensate if needed
RS = rc ; rc says use gallons vs percent
RC = 120 ; Reserve capacity gallons
DO = 30 ; Day Override (28 if no iron)
RT = 2:00 ; Regen time (default 2 AM)
BW = 5 ; Backwash (minutes)
Bd = 60 ; Brine draw minutes
RR = 5 ; Rapid Rinse minutes
BF = 8 ; Brine fill minutes
FM = ____0.7 ;
