Dishwasher salt light: why it stays on and when you should worry
What To Know
- The most common reason for the salt light to stay on is an insufficient salt level in the dishwasher’s salt reservoir.
- The dishwasher’s salt sensor may malfunction, leading it to detect a low salt level even when there is enough salt in the reservoir.
- A leaking salt reservoir can allow salt to escape, leading to an insufficient salt level and the salt light staying on.
Dishwashers are indispensable appliances in modern homes, making dishwashing a breeze. However, when the dishwasher salt light stays on, it can be a frustrating and confusing issue. This blog post delves deep into the reasons behind this common dishwasher problem and provides practical solutions to resolve it.
Reasons for Dishwasher Salt Light Staying On
1. Insufficient Salt Level: The most common reason for the salt light to stay on is an insufficient salt level in the dishwasher’s salt reservoir. Dishwashers require salt to soften the water, preventing scale buildup on dishes and the appliance’s components.
2. Clogged Salt Reservoir: If the salt reservoir is clogged with debris or food particles, it may prevent the salt from dissolving properly, causing the light to stay on.
3. Faulty Salt Sensor: The dishwasher’s salt sensor may malfunction, leading it to detect a low salt level even when there is enough salt in the reservoir.
4. Defective Dishwasher Circuit Board: In some cases, the dishwasher’s circuit board may be defective, causing the salt light to remain illuminated regardless of the actual salt level.
5. Loose or Corroded Electrical Connections: Loose or corroded electrical connections between the salt sensor and the circuit board can also trigger the salt light to stay on.
6. Water Hardness Setting: If the dishwasher’s water hardness setting is incorrect, it may not use enough salt to soften the water, resulting in the salt light staying on.
7. Leaking Salt Reservoir: A leaking salt reservoir can allow salt to escape, leading to an insufficient salt level and the salt light staying on.
Troubleshooting and Solutions
1. Check Salt Level and Add Salt: Ensure the dishwasher’s salt reservoir is filled with dishwasher salt. If the level is low, add salt until the reservoir is full.
2. Clean Salt Reservoir: Remove any debris or food particles from the salt reservoir using a damp cloth or sponge. Ensure the reservoir is clean before adding salt.
3. Test Salt Sensor: To test the salt sensor, add a small amount of water to the salt reservoir. If the salt light goes off, the sensor is likely faulty and needs to be replaced.
4. Replace Dishwasher Circuit Board: If the salt sensor test fails, the dishwasher’s circuit board may need to be replaced. This repair requires professional assistance.
5. Check Electrical Connections: Inspect the electrical connections between the salt sensor and the circuit board for any loose or corroded wires. Tighten any loose connections or replace damaged wires.
6. Adjust Water Hardness Setting: Refer to the dishwasher’s user manual to determine the correct water hardness setting for your area. Adjust the setting accordingly to ensure the dishwasher uses the appropriate amount of salt.
7. Repair Leaking Salt Reservoir: If the salt reservoir is leaking, identify the source of the leak and repair it using a sealant or replacement part.
Wrapping Up: Dishwasher Salt Light Mystery Solved

Quick Answers to Your FAQs
Q: Why does my dishwasher salt light stay on even after adding salt?
A: The salt reservoir may be clogged, the salt sensor may be faulty, or the electrical connections may be loose.
Q: Can I use regular table salt in my dishwasher?
A: No, only use dishwasher salt specifically designed for dishwashers. Regular table salt contains additives that can damage the appliance.
Q: How often should I add salt to my dishwasher?
A: The frequency depends on the water hardness and how often you use the dishwasher. Generally, it’s recommended to add salt every 2-3 months.
Q: What happens if I don’t add salt to my dishwasher?
A: Without salt, the water will not be softened, leading to scale buildup on dishes and the dishwasher’s components.
Q: Can I reset my dishwasher to turn off the salt light?
A: Resetting the dishwasher may temporarily turn off the salt light, but it will likely come back on if the underlying issue is not resolved.
