Problem
No soft water
Water hard sometimes
14
Possible Causes
Faucet or fixture where sample
was taken not plumbed to soft
water. NOTE: Be sure sample
i s from a faucet that does not mix
soft and hard water. For example,
a single lever kitchen faucet, if
the cold side is plumbed to hard
water
No salt in the brine tank
or salt bridged
Transformer unplugged
at wall outlet or power
cable to water softening
system not connected
Fuse blown or circuit
breaker popped on circuit
to electrical outlet
Electrical outlet on
a circuit that can be
switched off
Manual bypass valve in
bypass position
Valve drain hose pinched,
plugged, elevated too high
or otherwise restricted
Nozzle and venturi dirty,
incorrectly assembled or
damaged
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
What To Do
• To conserve salt, the installer may have isolated some
fixtures (outside faucets, toilets, etc.) from soft water.
From the outlet of the water softening system, trace the
water flow path, in house plumbing. If soft water is not
directed to a faucet or fixture where wanted, consult a
plumber.
• Check for a salt bridge or, if the tank is empty, refill with
recommended salt. Press (for 3 seconds) the TOUCH or
HOLD button to start an immediate regeneration and
restore soft water supply.
• Check for a loss of electrical power to the water softening
system due to any of these conditions and correct as
needed. With the power supply restored, observe the
control display and read Program Memory section.
NOTE: The electrical outlet for the water softening system
should be continuously live so it cannot be accidentally
switched off.
• Be sure the bypass valve stem is positioned properly.
Observe instruction on the decal at the end of the stem.
• Any restriction in this drain hose may prevent proper
operation of the nozzle and venturi and reduce or
prevent brine draw during regenerations.
• 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.
• Avoid using hot water during water softening system
regenerations because the water heater will refill with
hard water. See Automatic Hard Water Bypass During
Regeneration section.
• Press and release the SELECT button until HARDNESS shows
in the display. Be sure the number shown is the same as the
actual grains per gallon hardness of your water supply.
See 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.
