Probable Cause

Excess water in brine tank

Problem:

Drain line clogged, kinked, or frozen

Clogged brine line, brine line flow restrictor or Air check

valve

Clogged injector

Problem:

Regeneration sequence broken

Damaged magnetic lever

Faulty controller

Problem:

Softened water is salty

Damaged injector

Low inlet water pressure

Drain restrictor clogged

Salt line clogged or damaged

Too much water in brine tank

Unstable pressure of the supplied water, the formation

of a vacuum at the inlet

Brine valve leak

Problem:

Controller errors

E1 - Home position not detected

E2 - Engine malfunction

E3 - Shift of home position

E4 - Home position locked

E5 - Memory error

The water level must not reach the level of the float and the overflow fitting.

Solution

Remove the blockage, straighten the kink in the drain line

Clean the brine line, brine line flow restrictor and air

check valve. Remove dirt from the salt tank

Clean or replace injector. If the injector neck has been

removed, replace it with a new one.

Replace magnetic arm

Replace controller

Replace injector including the neck

Minimum working pressure 0.14 MPa

Remove blockage

Remove blockage, replace line if damaged

Check that the water level in the tank* and the brine

regeneration settings are correct. Check brine, drain

lines and tightness of valve assemblies

Install a check valve in front of the softener.

Stabilize the inlet pressure

Clean brine valve, replace brine valve seals

Turn the power off and on by unplugging and plugging in

the AC adapter. The search for the home position will

start again.

Make sure the controller is fully and securely attached to

the screw mechanism cover

Disable electric power and connect the motor. If it was

already connected, replace the motor.

Make sure the power supply is 12V AC voltage

The magnetic arm does not start from the correct home

position. The controller will automatically attempt to

adjust by searching for the home position and continue

regeneration.

Make sure the controller and magnetic arm are fully and

securely attached.

Transmission teeth not engaged or stripped. Something

has jammed the valve mechanism. Clear the jam, then to

reset the error, turn off and turn on the softener power

To reset the error, turn off and turn on the softener

power. If error persists, replace controller.
