Bosch Dishwasher Lights Meaning & Blinking Codes: Expert Guide & Fixes

What Do Bosch Dishwasher Lights Mean?

If your Bosch dishwasher lights are blinking, it’s usually an indicator of an error or maintenance need. The red light on the floor, the rinse aid symbol, the check water light, and a machine care warning help diagnose and fix issues.

This guide will explain the Bosch dishwasher’s light meanings and blinking. We will then provide step-by-step fixes to get it running smoothly.

Common Bosch Dishwasher Blinking Lights and Their Meanings

1. Bosch Dishwasher Blinking Red Light on the Floor

Meaning: The InfoLight on the floor is a feature found in many Bosch 800 Series Dishwashers. It remains solid red when the dishwasher is running. But, a blinking red light indicates that the dishwasher door is not fully closed or that the cycle was interrupted.

Solution:

• Ensure that the door is securely closed.
• Reset the dishwasher by pressing and holding the Start button for 3 seconds.
• Check for any obstructions in the latch area.

Reference: Bosch 800 Series models use Home Connect notifications for cycle completion.

2. Bosch Dishwasher Blinking Active Light

Meaning: The active light blinks when the dishwasher is stuck in an incomplete cycle or cannot start a wash cycle.

Solution:

• Press and hold the Start button for 10 seconds to reset the dishwasher.
• Check if the water supply is connected properly.
• Inspect whether the drain filter is clogged and clean it.

3. Bosch Dishwasher Blinking Red Lock Symbol

Meaning: The red lock symbol means that the child lock function is activated, preventing the dishwasher from starting.

Solution:

• Press and hold the lock button for 4–5 seconds to disable child lock.
• If the symbol persists, reset the dishwasher by unplugging it for a few minutes.

4. Blinking Salt Refill Indicator (S Symbol)

Meaning: The S symbol indicates that the dishwasher is low on dishwasher salt, which is essential for water softening.

Solution:

• Open the salt compartment and refill it with Bosch-approved dishwasher salt.
• Ensure the cap is securely closed to prevent salt leaks.

5. Blinking Rinse Aid Indicator (Sun Symbol)

Meaning: The sun symbol on the control panel indicates that the rinse aid dispenser needs refilling.

Solution:

• Fill the rinse aid compartment with Bosch-branded rinse aid.
• Adjust the rinse aid settings to suit your dishwashing needs.

6. Blinking Check Water Light (E15 Error Code)

Meaning: The dishwasher found a leak or too much moisture in the base pan. The AquaStop safety feature is now active.

Solution:

• Turn off the power supply and unplug the dishwasher.
• Tilt the dishwasher at a 45-degree angle to drain any excess water.
• Inspect for leaks from the hose, filter, or tub and repair as necessary.

7. Blinking E24 Error Light (Drainage Issue)

Meaning: An E24 error means the dishwasher isn’t draining properly due to a clog or kink in the drain hose.

Solution:

• Check the drain filter and clean any debris.
• Inspect the drain hose for kinks or blockages.
• Run the self-cleaning cycle to clear obstructions.
