Brine Solution Not Being Sucked In During Regeneration
Most problems occur when the Fleck 5600 is not drawing in the brine. Make sure the injector is drawing in
the brine:
1. Remove the brine tank tubing where it enters the Fleck 5600 control valve.
2. Press the Extra Cycle button and hold for several seconds until a backwash is started. After the
display stops blinking and it is in a backwash cycle, press the Extra Cycle button again, and it will
advance to the next cycle, which is the Brine Cycle, where it is supposed to suck in the brine solution.
3. If it is sucking strongly, check the brine tank float inside the brine well and make sure there are no
rubber bands around it, and that is free of obstructions. In some cases it may need to be replaced or
cleaned, if there is suction at the control valve, but no brine is being drawn in.
4. If there is NO suction at the control valve port where you removed the brine line tubing, then the
injector should be cleaned.
5. If the injector has been cleaned and there is still no suction check to make sure there is obstruction in
the backwash line; that the backwash line does not go up and over the softener more than several feet
(which causes pressure loss and the injector not to work correctly); finally check to make sure there is
enough pressure. If possible increase your water pressure to softener from your well pump and see if a
slightly increased pressure makes the injector work. We recommend a minimum 30 PSI but it does work
better if there is 40 to 50 minimum PSI.
System Not Backwashing Adequately
The other second main problem that may occur is if you do not have enough backwash flow rate to properly
clean the water softener. You can verify the backwash flow rate by running the drain line into a bucket and
timing it when the Fleck 5600 is in Cycle 1 or backwash. A 1.0 or 1.5 cubic foot system should have 5 gallons
per minute and a 2.5 cubic foot system should have 10 gallons per minute of backwash.
