Why does the salt indicator light in the dishwasher? How does it work and what does it say? In the article we will consider all the reasons, possible breakages and tell you what to do.

The manufacturer installed indicators on the control panel to use the dishwasher was easy. With their help you can trace, at what stage washing, whether there is enough detergent in the machine. All the notations are collected in the instructions, we will focus only on the salt icon.

What is the salt indicator for?

Since water in the regions of Russia is stiff and contains heavy impurities of calcium and magnesium, manufacturers have installed ion exchangers with resin in dishwashers. Particles of the resin attract heavy impurities, saturating the water with sodium. What this gives:

  • Prevents sedimentation of calcareous deposits on PMM parts.

The deposition of salts on the details of the mechanisms adversely affects them

  • Improves the quality of washing. Softened water dissolves the detergent better.
  • Saves dishes from white plaque and divorce.

The most important thing is that the ion exchanger prolongs the life of the dishwasher. When the resin in the tank ends, special salt comes to the rescue. How does she look?

The special salt is similar to the usual one, but its crystals are much larger. It goes through purification, so the composition contains only sodium chloride.How to choose a dishwasher salt, read in a separate article.

Distinctive visual differences of table salt from special

This is how the ion exchanger looks:

Typical standard structure of an ion exchanger

A special sensor detects the residue of salt in the machine. If the tool ends - the icon flashes, if it is already finished - it is lit. If the bulb in the dishwasher "Bosch" or "Siemens" is constantly lit and does not go out, it's time to replenish the ion exchanger.

In the first models of Hansa, Bosch this indicator is absent. Therefore, users have to periodically open and check the presence or absence of salt in the department.

The harder the water in the water pipe, the more salt is consumed. Often when buying equipment in the kit is a test strip to determine the amount of impurities. To find out the result, you can do this:

  • Call the water canal.
  • Use litmus test paper (test strip).

Users offer their methods, however, they do not give an accurate result. If the soap or shampoo does not foam well, and the white coating quickly builds up on the faucets and mixers, the hardness level is high.

Possible problems

It happens that you just filled the ion exchanger, but the indicator on the panel still burns. What to do?

  • Try restarting the machine. To do this, disconnect it from the network, then turn it on again.
  • After the restart, the work of the technique should be restored.

If this does not happen, mechanical cleaning will help:

  • Disconnect the PMM from the network.
  • With the help of a building vacuum cleaner, pour out the contents of the tank (salt and water).
  • You can use a rubber pear. Stir the contents and pour out.
  • Pour the complete separation of water.
  • Fill the crystals to the top.

The procedure for loading ion exchange salt is quite typical

  • Remove excess moisture from the pan.
  • Turn on the dishwasher.

Usually this is enough to stop the light from turning on. But if nothing has changed, you need to check the salt sensor.

  • Remove the side panel of the machine by unscrewing the fixing screws.
  • Remove the heat exchanger (if any). Behind him is the sensor.
  • Remove the sensor simply by unfastening the fasteners and unfastening the wiring.
  • Disassemble it and clean it from plaque and dirt.
  • Start the technique again.
  • Is the indicator on? Then you have to install a new sensor.

The problem is that it's not that easy to buy a part. Usually it is delivered only to the workshops. But you can send a request to the manufacturer or contact the nearest workshop.

You can operate the PMM with a non-working sensor, but then the indicator will not work. Determine the level of salt will have to be manually.

Decoding of each icon and indicator can be found in the instruction. Do not ignore the "messages" of the dishwasher, otherwise the problem may result in serious repairs.
