-After 3 seconds the valve will start to advance to the next step, 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 5900e 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.
Pot Perm Tank Not Filling with Enough Water
Sometimes if the pot perm 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.
Backwash Flow Rate
One problem that may occur is if you do not have enough backwash flow rate to properly clean
the Softener. You can verify the backwash flow rate by running the drain line into a bucket and
timing it when the 5900e 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.
In some cases, the 5900e may not be programmed correctly. See the 5900e service manual for
instructions on how to access the master programming.
What to Do If Your Filter Tank Does Not Sit Level On the Floor
Your black filter tank base is not glued to the bottom of your tank. Occasionally tank bases will
become crooked during shipment. If you find that that your tank does not sit level on the floor,
you can easily adjust it by holding the empty tank and rapping it on a concrete or solid floor
once or twice in order to level it.
