Fleck 5810 sxt ER 4

[Vaig]

Hello,

Can someone please help me with the ER 4 on my fleck 5810 sxt and how can i fix it?

I was getting that. Power cycling would fix it temporarily. I tried a UPS on the electrical, but the real fix was to replace the board in the valve. My old board was SV=3.0 (software version) in the diagnostics. The new board has SV=3.7

If power cycling does not make it start working, there is a good chance you have a broken piston. :-(

Thanks, @Reach4. I actually replaced the piston and seal with a brand-new kit. I also rechecked to make sure they aren't broken.
The 5810 SXT has been a real problem and no real support from Pentair or my installer.

What happens if you turn off the power for 15 seconds, and then turn the power back on?

 

[Vaig]

No matter how long I turned off the power, It kept rotating. So I finally removed the optical sensor and its connection, cleaned it well, put it back together, and reset the entire system it started working again.
But unfortunately, I have no idea what setting to use. Ran the manual regeneration cycle and now the water inside my home tastes salty. Not sure what settings to use. What information do you need to help me setup my fleck 5810 sxt valve again?

BLFC =0.125 or 0.25 or what?
Number of people or typical gallons per day.

 

[Vaig]

BLFC - 0.25
Number of people/typical gallons per day = 3 people/200 gallons a day.

I forgot to ask about the tank size (or cuft of resin) and the hardness. City water? If not, how much iron in the well water?

 

[Vaig]

City Water. No iron
I honestly don't know cuft of resin in the tank but the tank size is 10x44 so it's either 1 or 1.25 cuft so it may be a 32k or 40k grain system.

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 ; Same as (nominal grains/32,000)
Raw hardness : 9 ; including iron etc
Estimated gal/day ; 200 ; 60 gal per person prediction (auto-tunes)
Est days/regen ; 12.80 ; 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 = 23.0 ; capacity in 1000 grains
H = 9 ; 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 = 10 ; Brine fill minutes
FM = t1.2 (usual) ; t1.2 is default flow meter
RE = OFF ; Relay
VR = OFF ; ?
