Error Code: SALT SYMBOL (S-SHAPED ARROWS) Difficulty: Easy
Problem: The dishwasher salt reservoir needs to be refilled.
How to Fix SALT SYMBOL (S-SHAPED ARROWS) Error (Step-by-Step)
- Pull out the bottom rack completely to access the floor of the dishwasher.
- Locate the large, round cap for the salt reservoir, usually off to one side.
- Unscrew the cap by turning it counter-clockwise and set it aside. It is normal to see water inside the reservoir.
- Insert the funnel that came with your dishwasher into the opening.
- Pour only dishwasher-specific salt into the funnel until the reservoir is completely full.
- Remove the funnel and wipe away any loose salt granules from the threads of the opening.
- Screw the cap back on tightly and run a short rinse cycle to distribute the salt and clear the sensor.
- Turn the appliance off, wait about 2 minutes, then turn it back on.

What to Check Next on This Bosch Dishwasher
Salt symbol: The salt indicator is tied to the water-softening system. It usually needs refill or setting checks before parts are considered.
- Refill the salt reservoir with dishwasher salt only, then wipe spilled salt from the tub before running a rinse or short cycle.
- Check the water hardness setting if the light returns quickly or dishes show film despite enough salt.
- If the reservoir is full but the symbol never clears, inspect the cap, float or sensor area, wiring, and control input before replacing parts.
If the symptom returns after these checks, use the full Bosch model number from the door tag before ordering any part. The same display message can point to different parts depending on the exact model and what the dishwasher does during fill, wash, drain, or dry.
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
