Problem Possible Cause Solution
No Soft 
Water After 
Regeneration
No salt in brine cabinet. Add salt.
Sediment in brine cabinet has plugged 
the brine line and air check/draw tube.
Remove the brine line and flush clean.
Remove the air check/draw tube and 
flush with clean water. Clean injector 
assembly. Clean any sediment from 
brine cabinet.
Flow control is plugged.
Remove brine piston housing and clear 
debris from the flow control.
Drain line is pinched, frozen, or 
restricted.
Straighten, thaw, or unclog the drain 
line.
Clogged injector assembly.
Remove injector cap and clean nozzle 
and throat with a wooden toothpick. 
Replace entire assembly if throat 
removed.
Salt bridge has formed due to high 
humidity or the wrong kind of salt.
Test with a blunt object like a broom 
handle. Push the handle into the salt 
to dislodge the salt bridge, or use hot 
water around the inside perimeter to 
loosen salt.
No Soft Water
The Bypass Valve is in the Bypass 
Position.
Place the Bypass Valve in the Service 
position.
Appliance is plumbed backwards.
Check that appliance is plumbed 
correctly.
Extended power outage.
Reset the time of day and regenerate 
the unit.
Water hardness has increased.
Re-test the water and re-enter a new 
setting number.
Not metering water.
Flow should be indicated with water 
usage. If no flow, see below.
No Flow Is 
Indicated When 
Water Is Flowing
The Bypass Valve is in the Bypass 
position.
Place the Bypass Valve in the Service 
position.
Appliance is plumbed backwards.
Check that appliance is plumbed 
correctly.
Sensor not receiving signal from 
magnet on turbine.
Remove sensor from bypass housing. 
Test with magnet on either flat side 
of sensor. If flow is indicated, check 
turbine. If no flow, replace sensor.
Turbine is jammed.
Remove Bypass Valve and clear debris 
from turbine.
Flow Indicated 
When Water Is 
Not Being Used
The household plumbing system has 
a leak.
Repair the leak.
No Read-Out In 
Display
Electric cord is unplugged. Plug in the transformer.
No electric power at outlet.
Check power source. Make sure outlet 
is not controlled by a switch.
Defective transformer.
Test with voltmeter for 12 VAC at 
control. If less than 10 VAC replace the 
transformer.
Defective circuit board.
With 12 VAC present at controller, 
replace the controller.
Problem Possible Cause Solution
Appliance Stays 
In Regeneration
Controller not attached properly.
Make sure the controller is pushed all 
the way onto the cover plate.
Defective magnet disk. Replace magnet disk.
Foreign object in main control valve.
Remove foreign object(s) from the 
main control valve.
Broken valve assembly. Motor running. Repair the valve assembly.
Excess Water In 
Brine Tank
Restricted, frozen, or pinched drain 
line.
Remove restriction, thaw, or straighten 
drain line.
Plugged brine line, brine line flow 
control, or air check/draw tube.
Clean flow control, air check/draw 
tube, and brine line. Clean any 
sediment from the brine cabinet.
Plugged injector assembly.
Clean or replace injector. Replace 
entire assembly if throat removed.
Salty Water
Plugged injector.
Replace injector screen, nozzle, and 
throat.
Low water pressure.
Maintain minimum pressure of 30 psi 
(2.1 bar).
Drain line or flow control is restricted. Remove restriction.
Brine line restricted or crimped. Remove restriction, replace if crimped.
Excessive amount of water in brine 
cabinet.
Verify correct water level relative to 
salt setting. Estimated amount of 
water should be 2-12". Check brine 
line and fittings for loose connections.
Intermittent pressure drop from feed 
source.
Install check valve on the inlet water 
line to the appliance (check local 
plumbing codes first).
Brine valve drips water back to brine 
tank.
Clean brine valve housing, replace 
piston assembly.
Controller Error 
Messages
“E1” Home not found.
Cycle power by unplugging the 
transformer and plugging it back in. It 
will look for Home again. Ensure the 
controller is pushed all the way onto 
the cover plate.
“E2” Motor error.
All wires should be unplugged and 
replugged, sequence is motor, sensor, 
and power cord. Plug motor in and 
cycle power. If it is already plugged in, 
then motor wiring or the motor plug is 
defective. This could also be a problem 
with the computer.
“E3” Home offset.
Disk did not start in proper home 
location. Cycle power controller will 
automatically try to reset itself by 
finding Home and continuing the 
regeneration. Ensure the controller 
is pushed all the way onto the cover 
plate.
“E4” Home latched.
Gear teeth are not engaged, gear is 
stripped, or something is jammed in 
the valve. Cycle the power to reset.
“E5” Memory error. Replace controller.
