page first and you may not need to call for service.
NO SOFT WATER – Most Common Problems:
Check the following before calling for service
• Salt in softener...at least 1/3 full.
• By pass valve in "Service" position. Knob should be in the OUT position.
• Check hardness setting in control. Verify hardness of supply water. Water
hardness can vary throughout the year (see Programming the Control section).
• Salt Bridge, water not in contact with salt (see Breaking a Salt Bridge section
Problem
Possible Causes
No soft water
Faucet or fixture where sample was
taken not plumbed to soft water.
NOTE: Be sure sample is 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 softener 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
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 faceplate time
display and read Program Memory section.
NOTE: The electrical outlet for the softener should be continuously
live so it cannot be accidentally switched off.
• Be sure the bypass valve stem is positioned properly, with the
knob in the OUT position. Observe instructions 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.
• Refer to Cleaning the Nozzle and Venturi Assembly instructions.
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.
