problem cause solutIon
No soft water after regeneration. No salt in brine cabinet. Add salt (refer to “Regenerate” Page 6).
Sediment in brine tank has plugged the brine line and air
check (Page 16).
Remove air check draw tube and flush with clean water. Clean
injector assembly. Clean any sediment from brine cabinet.
Drain line is pinched, frozen or restricted. Straighten, thaw or unclog the drain line.
Clogged injector assembly (Page 12). Remove injector cap and clean nozzle and throat with a
wooden toothpick. Replace throat if removed.
Salt bridge has formed. High humidity or the wrong kind of salt can create a salt
bridge. This is a crust that forms an empty space between the
water and salt. To test, use a blunt object like a broom handle.
Push the handle into the salt to dislodge the salt bridge.
No soft water. The plumbing bypass valve is in the bypass position
(Page 4).
Place bypass valve in the service position.
Appliance is plumbed backwards. Check that appliance is plumbed correctly.
Water hardness has increased. Reset water hardness.
Not metering water. Flow should be indicated with water usage. If no flow, see
below.
No flow is indicated when water is flowing. The plumbing bypass valve is in the bypass position
(Page 4).
Place bypass valve in the service position.
Appliance is plumbed backwards. Check that appliance is plumbed correctly.
Sensor not receiving signal from magnet on turbine
(Page 13).
Remove sensor from IO housing. Test by placing magnet on
the sensor chip. If waterMizer ® blinks, replace turbine. If not,
replace sensor.
Flow is indicated when water is not being used. There is a leak in your household plumbing system. Repair the leak.
No read-out in display. Electric cord is unplugged. Plug in transformer.
No electric power at outlet. Check power source. Make sure outlet is not controlled by a
switch.
Defective transformer (Figure 8). Test with volt meter for 12 VAC at control. If 0 VAC, replace
transformer.
Defective circuit board (Figure 10). With 12 VAC present at controller, replace circuit board.
Appliance stays in regeneration. Cycle numbers
remain flashing.
Computer control not attached properly. Make sure computer control is pushed all the way onto drive
end cap.
Foreign object in valve body. Remove foreign objects from valve body.
Broken valve assembly. Motor running Magnet disc not
turning (Pages 14)
Replace drive end cap.
Excess water in brine tank. Restricted, frozen or pinched drain line. Remove restriction, thaw or straighten drain line.
Should be approximately 8 - 10"
with salt.
Plugged brine line, brine line flow control or air check
(Pages 15).
Clean flow control, air check and brine line. Clean any sedi-
ment from brine cabinet.
Plugged injector assembly (Pages 12). Replace drive end cap.
Sticking brine refill valve. Remove valve. Lubricate piston with silicone grease and reas-
semble.
Not regenerating in proper sequence. Magnet disc defective. Replace magnet disc.
Defective position sensor. Replace control.
Salty water. Plugged Injector. Clean injector screen, nozzle and throat.
Low water pressure. Maintain min. pressure of 20 psi.
Drain line or flow control restricted. Remove restrictions.
Brine line restricted or crimped. Remove restrictions, replace if crimped.
Excessive amount of water in brine cabinet. Verify correct water level relative to salt setting. Check lines
for loose connections.
Intermittent pressure drop from feed source. Verify adequate pressure and volume of water supply.
