Problem
Water hard sometimes
Water feels slippery
after installation of
water softening system
Water softening system
not using any salt
Water is blue color
after water softening
system was installed
Water softening system
not regenerating
Cloudiness on glassware
(automatic dishwashers)
Excessive/high level
of water in brine tank
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
Absence of hardness minerals
Water softening system is a
"demand" unit
Possible salt bridge
Possible plugged nozzle and venturi
Acidic water in copper plumbing
Meter turbine stuck
Sensor wire corroded
No power to unit
Mechanical defect
Combination of soft water and
too much detergent
Valve drain hose pinched,
plugged, elevated too high
or otherwise restricted
Nozzle and venturi dirty, incorrectly
assembled or damaged
What To Do
• 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,
page 11.
• Press the MODE button until HARDNESS appears in the
display. 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.
• 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 About the Water Softener System section, page 12.
• See the About the Water Softener System section, page 12.
• Have the water tested at once.
WARNING:
Do not drink the water until problem
has been corrected.
• See the Service: Manually Initiated Electronics Diagnostics
section for troubleshooting procedures, page 15.
• Call for service.
• See the Service: Manually Initiated Electronics Diagnostics
section for troubleshooting procedures, page 15.
• Call for service.
• Check the circuit breaker or fuses.
• Call for service.
• 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 nozzle and venturi and reduce or prevent
brine draw during recharge.
• See the Cleaning the Nozzle and Venturi Assembly section,
page 12. With water pressure to the water softening system
off, take the nozzle assembly apart. Inspect, clean and
replace as needed. Any foreign particle(s), scratches, nicks,
etc., in the passages can prevent operation. Be sure holes
in the gasket are centered over holes in the housing.
