TROUBLESHOOTING

SOLUTION
Add salt.
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.
Remove brine piston housing and
clear debris from the flow control.
Straighten, thaw, or unclog the
drain line.
Remove injector cap and clean
nozzle and throat with a wooden
toothpick. Replace entire assembly
if throat removed.
Test with a blunt object like a broom
handle. Push the handle into the salt

water around the inside perimeter to
loosen salt.
Place the Bypass Valve in the
Service position.
Check that appliance is plumbed
correctly.
Reset the time of day and regenerate
the unit.
Re-test the water and re-enter a new
setting number.
Flow should be indicated with water
usage. If no flow, see below.
Place the Bypass Valve in the Service
position.
Check that appliance is plumbed
correctly.
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.
Remove Bypass Valve and clear
debris from turbine.
Repair the leak.
Plug in the transformer.
Check power source. Make sure outlet
