Problem Possible Cause What to do
Water hard
sometimes
Using hot water while the
water softening system is
regenerating
• Avoid using hot water during water softening
system recharge because the water heater will
refill with hard water. See Automatic Hard Water
Bypass During Recharge section.
Control HARDNESS number
setting too low
• Press MODE/SET button until arrow points to
HARDNESS. Be sure the number shown is the
same as the actual grains per gallon hardness of
your water supply. See Programming the Control
section if a change in setting is needed.
Grains of hardness in your
water supply have increased
• 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.
Water feels
slippery after
installation of
water softener
Absence of hardness minerals • 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.
• See the Adjusting your Water Hardness section.
Water Softener not
using any salt
Water softening system is a
“demand” unit
• Does not use much salt to regenerate - very
efficient.
Possible salt bridge • See the Breaking a Salt Bridge section.
Possible plugged nozzle and
venturi
• See the Cleaning the Nozzle and Venturi
Assembly section.
Water is blue
color after water
softener was
installed
Acidic water in copper
plumbing
• Have the water tested at once.
Water softener not
regenerating
Meter turbine stuck • See the Manually Initiated Electronics
Diagnostics section for troubleshooting
procedures.
• Call for service.
Sensor wire not plugged into
the control
• See the Manually Initiated Electronics
Diagnostics section for troubleshooting
procedures.
• Call for service.
No power to unit • Check the circuit breaker or fuses.
Mechanical defect • Call for service.
Cloudiness
on glassware
(automatic
dishwashers)
Combination of soft water and
too much detergent
• 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.
