No More fresh water!

Cillit Ruby

And There you go !
A new failure on my Cillit Rubis Bio Intégral 90 water softener, some 12 years old ...
I noticed these last few days that the water from my taps was supplying me ... hard water ( about 26 ° Th )

Traces of lime everywhere on the taps, the shower mirror, and the dishes once again indicate a malfunction of the softener.
So I went to see it more closely and ... did not see anything precisely ...
punctuation iconBefore reading the rest, know that my responsibility can in no way be engaged for any damage both technical and physical that could be caused to you or your equipment, both through carelessness and ignorance.

First usage checks

  • the input micro-fiber filter is correct although a little dirty ( yes, limestone ... ) but not clogged ...
  • I still have the value of almost a 25Kg bag of salt in the bin ...
  • there is water in the brine well ...
  • no water leak (s) at first sight ...
  • switching off / depending on the machine, same problem ...

Hell ... what can it be?
While looking on the Internet, I arrived after very many and long searches on an information allowing to remove some doubts ...
It is in fact a question of verifying in a very simple way if the device sucks the brine correctly, or not. ..
To do this, proceed as follows:

Experimentation

  • switch off the device by unplugging the power supply
  • take an empty water bottle ( preferably 2L given the dimensions of the brine regulator foot ... ) and cut it just below the neck at the level of the narrowing.
    Prepared in this way, the bottle I use measures 230 mm for an internal diameter of 90 mm, an essential size given the height of the float ( dimension at 110 mm in my case ).
  • open the brine container located in the brine tank and remove the complete brine regulator without disconnecting it !
  • it is not necessary to touch the adjustment of the X value of the float, in any case mine triggered the stop a few centimeters before the overflow ...
  • possibly use a small spring clip( not too powerful, so as not to flatten the tube ) to hold the tube of the electrochlorination probe, this so that the float can operate
    in the bottle without any friction, this is very important ...
    we can see mine at the very top on the edge of the brine tank. The height of the bottle from the ground is not important, I placed the bucket to raise it so as not to damage the probe tube ...
  • reconnect the device

From this moment, the softener will, thanks to the float which actuates the opening / closing valve of the brine regulator foot, automatically fill with water, and thus will cause the bottle to fill.
When the water reaches the level of the float, the latter must trigger the stop of filling.
This step is important, it makes it possible to check on the one hand the correct functioning of the float, but also the good continuity of the connection between the hydro-ejector ( via the electrochlorination probe for the BIO versions ... ) and the brine regulator.

If everything went well, your bottle is almost full, and the device has stopped filling with water, it is now on standby ( as before doing this operation ... )

TEST modeControl panel [320x121px]

This is where it gets interesting!
Indeed, your device just like mine has a TEST mode ( I urge you to read your user manual, which may differ from one model to another ... ), intended for the After-Sales Service Technician.
It is an almost banal operation, which everyone can perform without great difficulty.

To enter this mode, simultaneously press keys 13 and 15 for 5s.
At this time, the display shows the regeneration time in minutes ( 044 for mine ), and the first backwash cycle begins.
It is possible to go to the next cycle by pressing button 14 . It is then the suction cycle which begins.
The last cycle is the quick rinse cycle. A final press of the [Program] key 14 exits the Test mode, and the device then displays again the volume in liters of fresh water available before the next regeneration.

Is the device broken? view of the valve ...

The interesting cycle is the second, that of the brine suction.
Normally during this step, you should see the water level in your bottle decrease ( very slowly ... ) until it is almost empty.
If this is not the case, then you must first check the good condition of the connection of the brine suction tube, the small gray colored tube ( see image opposite ... ).

In mine, the plastic nut that holds the tube firmly at the exit of the electrochlorination probe was split.
This did not cause a water leak, but an air intake. In fact, during the suction sequence, the machine sucked in air instead of liquid, which caused it to no longer produce fresh water.

My softener is not really old, and it is stored under cover in a wooden chest in the cellar. The aging of the plastic is probably the cause of the problem.

I contacted the CILLIT agency by phone, and I must say that I was very well received.
My interlocutor took the time to listen to the report of my findings, and immediately sent me a new nut to replace the defective one!
Well done, may she be thanked again!

Today, my softener is working correctly again, with soft water at 6 ° Th for hard water at 30 ° Th.
End of the episode.

Also note that the instructions for the new "AQUIUM" model offer the exploded view of the valve, identical to that of the "Rubis" ...
