Troubleshooting Tips
Problem
Water hard sometimes
Water feels slippery
after installation of
water softening system
Water softening system Water softening system is a
not using any salt
Water is blue color
after water softening
system was installed
Cloudiness on glassware Combination of soft water and
(automatic dishwashers) too much detergent
Excessive/high level
of water in brine tank
20
Possible Causes
Using hot water while the water
softening system is regenerating
Control HARDNESS number setting
too low
Grains of hardness in your water
supply have increased
System capacity inputs, Salt per
Regeneration and Capacity set too low
If resin bed is fully exhausted, for
example, after a malfunction, one
regeneration cycle may not fully
restore capacity
Absence of hardness minerals
"demand" unit
Possible salt bridge
Possible plugged injector and screen
Acidic water in copper plumbing
Valve drain hose pinched,
plugged, elevated too high
or otherwise restricted
Injector or injector screen dirty
What To Do
• Avoid using hot water during water softening system
regeneration because the water heater will refill with hard water.
• Press the SET button to enter a new value. Be sure the
number shown is the same as the actual grains per gallon
hardness of your water supply. See the Programming
the Control section if a change in the setting is needed.
• Water hardness can change over time, especially in well water.
To check, have the water tested by a water analysis laboratory
or call your local water department. Adjust the hardness
number setting as needed.
• See Salt per Regen and Capacity section so system will
regenerate about every 5 days. See instructions on pages 12
and 13.
• Complete "back to back" regenerations. Initiate Regeneration
cycle, wait 1 minute, then press REGEN again.
See page 14.
• This is normal. Hardness in water gives it the abrasive feel
you may have been accustomed to. The slippery feel is the
clean feel of soft water.
• Does not use much salt to regenerate—very efficient.
• See the Breaking a Salt Bridge section.
• See the Cleaning the Injector and Screen section.
• Have the water tested at once.
• This is called etching and is permanent. To prevent this
from happening, use less detergent if you have soft water.
Wash glassware in the shortest cycle that will get them clean.
• Any restriction in this drain hose may prevent proper
operation of the injector and screen and reduce or prevent
brine draw during regeneration.
• See the Cleaning the Injector and Screen section, page 17.
With water pressure to the water softening system off,
remove the injector and injector screen. Thoroughly clean
and flush. Check for any damage. Reassemble to valve
assembly.
