Your dishwasher salt light stays on because the sensor sees low salt levels, even if you’ve just refilled it. This happens due to trapped air bubbles, a faulty sensor, or salt bridging in the reservoir. To fix this, stir the salt in the compartment, reset the dishwasher, or clean the sensor.
What Does the Salt Light Mean on My Dishwasher?
The salt light on a dishwasher indicates that the water softener salt level is low. Dishwasher salt prevents limescale buildup and ensures better cleaning performance. If the light stays on after refilling, it may be a sensor issue or trapped air inside the salt compartment.

Why Does My Dishwasher Keep Saying It Needs Salt?
Your dishwasher shows “add salt” because it might need more salt or has trouble detecting the refill. Common reasons include:
- Salt Bridging: A hard crust forms in the salt reservoir. This stops new salt from dissolving correctly.
- Air Bubbles: If air is trapped inside, the sensor may not register the added dishwasher salt.
- Sensor Malfunction: A broken sensor might wrongly sense the salt level. This can keep the salt light on, even when it’s full.
Why Is the Light Still On After Adding Salt to My Dishwasher?
If the dishwasher salt light stays on after refilling, it could be due to air bubbles or a sensor issue. Here’s how to fix it:
- Check the Salt Level: Ensure the reservoir is full of dishwasher salt.
- Stir the Salt: Use a spoon to gently break any salt clumps and release air bubbles.
- Reset the Dishwasher: Turn it off for 5 minutes, then restart it to refresh the salt level sensor.
- Clean the Sensor: Wipe the inside of the salt compartment to remove any stuck particles or debris.

Why Is My Dishwasher Salt Light Still On?
The dishwasher salt light stays on because the sensor can’t find the new salt. Try these solutions:
- Fill to the Max Level: If it’s underbilled, the dishwasher won’t see the salt added.
- Break Salt Bridges: If a hard crust forms over the salt, it won’t dissolve properly, causing the light to remain on.
- Run a short cycle: This helps to distribute the salt and reset the dishwasher salt indicator.
Why Is the Red Light on My Dishwasher Salt?
A red salt light on your dishwasher means the salt reservoir is empty, or the sensor can’t detect the added salt. Possible reasons:
- Reservoir Not Fully Refilled: Always top it up completely.
- Clogged Salt Chamber: Clean the compartment to ensure an uninterrupted salt flow.
- Faulty Sensor: If none of the above fixes the issue, the sensor might need repair or replacement.
How Do You Know When Dishwasher Salt Is Full?
To check if your dishwasher salt reservoir is full:
- Look for Overflowing Water: If water spills out while filling, it is full.
- Monitor Dishwasher Performance: If dishes come out clean and free from spots, the salt is at an optimal level.
- Check the Light: If it turns off after refilling, the dishwasher salt level is enough.
What to Do After Adding Salt to Your Dishwasher?
After refilling dishwasher salt, follow these steps:
- Run a Quick Cycle: This dissolves the new salt granules and spreads them evenly.
- Wipe Away Spilled Salt: Excess salt around the reservoir can affect the sensor’s accuracy.
- Check for Leaks: Ensure the salt cap is tightly sealed to prevent leaks or malfunctions.
Would No Salt in a Dishwasher Stop It from working?
A dishwasher without salt will still function, but may experience:
- Limescale Buildup: Hard water deposits can clog internal components.
- Reduced Cleaning Performance: Dishes may come out with spots and streaks.
- Long-Term Damage: Mineral accumulation can shorten the dishwasher’s lifespan.
How Long Should Salt Last in a Dishwasher?
On average, dishwasher salt lasts between 1–3 months, depending on:
- Water Hardness: Harder water requires more frequent salt refills.
- Dishwasher Usage: Frequent use means faster salt consumption.
- Reservoir Size: Larger reservoirs hold more salt, extending refill intervals.
