TROUBLE SHOOTING
Issues Root causes How to fix
The displays shows alternative CHECK
and SALT
There is not enough salt left in the tank
OR
The device detects a regeneration flaw.
Refill the tank with salt.
If it does not look to need refill, contact the tech-
nical service.
The time on the display is not correct
The seasonal time change has not been done
OR
A power cut occurred and the data recovery
did not work (battery KO).
Reset the timing (see chapter SETTING).
If the problem comes up again, contact the technical
service.
No display
The power is off
OR
There is an electric or electronic failure.
Check the power outlet where the device is plugged.
If the power outlet works, contact the technical
service.
Water flow through the evacuation
tube (8)
The device is regenerating (which means that
there is no problem)
OR
The internal components meet a failure.
Check that the device displays
REGE 1, REGE 2 or
REGE 3
.
If not, contact the technical service.
Water overflow from the salt tank (10)
The brining chain does not properly close
or leaks.
Check the connection between the bring tube (9)
and the brine valve (5) .
If the problem remains, contact the technical service.
The water delivered by the device does
no longer look softened (lime scale
coming back, etc.)
Many possible root causes. Step through all
the checks on next column.
Measure the residual hardness once first, then after
each of the following steps until the result is OK.
Check that the bypass is open to direct the water to
the softener. If not, change its position.
Check that there is still salt in the tank. If not, refill it.
Check if the type of salt is well selected in the
programming.
Check that the filter element is not clogged. If so
replace it.
Go again through the blending procedure (see
chapter COMMISSIONING)
If the problem remains, contact the technical service.
