More Troubleshooting Tips
Brine Solution Not Being Sucked In During Regeneration
Most problems occur when the 5700-E 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 5700-E control valve.
2.
Press and hold the regen button (Button with 3 arrows) until BW flashes and the number of minutes
that you programmed (10 is default) will display After the display stops blinking and it is in a
backwash cycle, press the regen 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 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 5700-E is in Cycle 1 or backwash. A 1.0 or 1.5 cubic foot system should have 2.0 gallons per
minute and a 2.5 cubic foot system should have 4.0 gallons per minute of backwash.
System Not Programmed Correctly – PROGRAM SETTINGS
In some cases, the 5700-E may not be programmed correctly, try to verify the correct programming.
Brine Tank Not Filling With Enough Water
Sometimes if the brine tank is not filling adequately, it is possible that the float assembly in the tank is set too
low. You would want the float to be several inches above the air check valve inside the tank. This will allow
for enough water to be added to the tank before shutting the brine fill cycle. If necessary, pull the float
assembly rod up to the appropriate height, and cut the rod at that height, leaving while keeping the rubber
washers the adequate space to hold the float in place.
