The salt light on a dishwasher typically indicates that the dishwasher needs more salt added to the water-softening system. Adding salt to a dishwasher is to help remove hard water minerals from the water, which can cause spots on dishes and damage to the dishwasher over time.

If your dishwasher salt light is staying on, there could be a few possible reasons:

  1. The salt reservoir is empty: If the salt reservoir is empty, the dishwasher will not be able to soften the water, and the salt light will remain on. To fix this issue, add salt to the reservoir.
  2. The salt level sensor is faulty: The salt level sensor in your dishwasher can become broken over time, which may cause the salt light to stay on even if there is enough salt in the reservoir. In this case, you may need to replace the salt level sensor.
  3. The dishwasher’s water softening system is malfunctioning: If it is not working correctly, it may be unable to remove hard water minerals from the water properly. This can cause the salt light to remain on even if you have added salt to the reservoir. If you suspect this is the case, you may need to call a professional to diagnose and repair the problem.

Overall, if you are unsure why your dishwasher salt light is staying on, it is best to consult the manufacturer’s instructions or seek assistance from a professional technician.

The salt level indicator in your dishwasher operates using a reed switch that is activated by a float in the salty water. If the float appears to be stuck, try tapping the softener (where you add the salt) and stirring the water inside the softener. It is also important to ensure that you have added enough salt. This is not a serious issue, and the above steps should resolve the problem.

An alternative if the light stays on is to fill the salt reservoir with 2 liters of hot water. After that, started the dishwasher on an intensive 65-degree wash cycle, with the reservoir cap open. Once the cycle is finished, I refilled the reservoir with salt. The salt indicator light should now be off. Read more here about how much salt to put into the dishwasher.
