NO SOFT WATER – Most Common Problems:

Check the following before calling for service

•Not enough salt in softener--should be at least 1/3 full.

•Bypass valve in “Bypass” position--should be in “Service” position. Knob should be in the OUT position.

•Hardness setting too low--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.

No salt in the brine tank or salt bridged

•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.

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

•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.

Manual bypass valve in bypass position • 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.

Valve drain hose pinched, plugged, elevated too high or otherwise restricted

•Any restriction in this drain hose may prevent proper operation of the nozzle and venturi and reduce or prevent brine draw during regenerations.

Nozzle and venturi dirty, incorrectly assembled or damaged

•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.
