TROUBLE SHOOTING GUIDE
Problem Possible Solutions
LEVEL 1
Recommended for the home owner
** IMPORTANT **
before attempting any trouble shooting be sure to test the water or have the water tested.
The tests should include the raw water, the hot treated water, and the cold treated water.
Delivers untreated Water Bypass is closed bypassing raw water past the unit - Return bypass valve to the open position to service
the home - See page 16
Delivers untreated Water
Bypass loop in the homes plumbing - Close outlet valve only on conditioner bypass, open nearest
conditioned water line, if no water flow then there is not a bypass in the plumbing if there is water flow
then there is a hidden bypass in the plumbing (contact plumber)
Delivers untreated water
No salt or low salt level - Fill salt to above the water level in the salt tank low salt will affect the
conditioners capacity. - See Page 23
Delivers untreated water Not programmed correctly for current application - Verify programming correct hardness level and
amount of people in the home if necessary. - See page 21
Excessive water in the salt tank Refer to Maintenance Page 24 cleaning the injectors and cleaning the salt tank
Not regenerating automatically, not metering water flow Check diagnostics for last regeneration - See page 4
Open nearest conditioned water outlet and check if gallons is counting down, if not counting down see
level 2 meter not counting down **
Not using salt
Injectors or injector screen plugged Clean and or replace injectors and screen -
See page 29
Salt Bridged in salt tank - See page 24
Not regenerating automatically - Alarms Caused by a power outage or brown out during regeneration – unplug power for 30 seconds then
re-connect if alarm continues - See Level 2 **
Unit regenerates but does not use salt Clean and or replace injectors - See Maintenance on page 24
Unit regenerates but does not use salt Drain line flow control is plugged – clean drain line flow control to ensure there are no kinks, or
restrictions in the drain line -
See page 33
Using too much salt or more salt than expected Check programming – is the unit set properly for salt efficiency, is the programming correct for
hardness and people.
Alarms after regeneration
Caused by a power outage or brown out during regeneration – unplug power for 30 seconds then
reconnect if alarm continues - S ee Level 2 **
Alarms after regeneration Corroded or damaged rear circuit
– replace circuit
see page 33
Discolored water Result of city / town supply being contaminated
– check with local authority to see if there has
been water main activity in your area if there has been then simply manually regenerate the unit a
couple of times in a row to clear the color.
Discolored water Iron Bleed through – if there are small amounts of iron in your raw water supply eventually it will
build up in the resin and could result in bleed through.
– review settings to compensate for iron in the water - S ee page 21
- Contact your dealer or local plumbing supply store to obtain an approved resin cleaner. Use resin
cleaner to clean the resin as directed. For permanent maintenance if required add in an automatic
feeder - S ee page 25
Excessive pressure loss Check unit specifications - peak or continuous service flow rates maybe exceeding capacity causing
the unit to be restrictive due to size -

contact your dealer if necessary.
