A blinking red light on a Bosch dishwasher often indicates an issue with the door latch, water supply, or control board. Start by ensuring the door is securely closed, and the latch clicks into place. Reset the dishwasher and check the water inlet valve for blockages. If the issue persists, inspect the control board or call a technician.
Let’s dive in.
Why Bosch Dishwasher Lights Blink and Flash
Bosch dishwashers are designed with advanced diagnostic systems. The lights serve as alerts to let you know when something’s wrong or when the machine is actively working. But, not all flashing or blinking lights say a problem. For example, the Bosch dishwasher red light on the floor is often a normal sign that the dishwasher is in operation.
Common Light Indicators and Their Meanings
- Red Light on the Floor (Active Light System)
- This light projects onto your floor to show the dishwasher is running.
- If Blinking: The door may not be fully closed, or there could be an issue with the latch mechanism.
- Flashing Lights on the Control Panel
- Why It Happens: Water supply issues, clogged filters, or an improperly latched door are common culprits.
- Check for these problems first before diving into more complicated fixes.
- Bosch Dishwasher Blinking White Light
- This usually means the rinse aid dispenser is empty or there’s an issue with the cycle you’ve selected.

How to Troubleshoot Bosch Dishwasher Lights
From personal experience, the key to troubleshooting is to go step by step. Don’t overcomplicate things right away. Often, the simplest solution is the right one.
1. Red Light on Floor Not Turning Off
- Check the Door: Ensure it’s fully closed and latched. A misaligned door can prevent the cycle from starting or finishing.
- Inspect the Cycle: If the red light keeps blinking after the wash cycle is over, the dishwasher might be stuck in a loop. Reset the dishwasher by holding down the start button for 3–5 seconds.
2. Bosch Dishwasher Lights Flashing and Won’t Start
- Water Supply Issues:
- Make sure the water valve is open, and the hose isn’t kinked.
- One time, I discovered my dog had knocked into the water supply hose, blocking the flow. A quick adjustment fixed the problem.
- Blocked Filters:
- Pull out the bottom rack and unscrew the filter. Rinse it under warm water to remove debris.
- Power Reset:
- Unplug the dishwasher for a minute or two to reset the system.
3. Bosch 500 and 800 Series Blinking Red Light
These high-end models often display a blinking red light on the floor due to sensor miscommunication.
- Solution:
- Check the water inlet valve. If the valve is partially blocked, it can cause the sensor to misfire.
- Clean the spray arms to ensure proper water flow.

Taking the time to learn what the lights mean can save you money, time, and stress. Also, troubleshooting on your own is incredibly satisfying. There’s nothing like fixing a problem without calling for help. I’ve tackled everything from a blinking red light to a full-on system reset. It’s made me more confident with appliance repairs.
