- The door is not closed properly
- There is a water supply problem
- The filter or drain is blocked
- There is a leak or overflow
- The dishwasher is in child lock mode
- A general error has occurred
Understanding Bosch Dishwasher Light Signals
To fix the problem, you need to know what the blinking pattern means. Here’s a quick comparison of common Bosch dishwasher light signals:| Light Signal | Meaning | Action Needed |
|---|---|---|
| Steady Red Light (InfoLight) | Cycle running normally | No action required |
| Blinking Red Light (InfoLight or Panel) | Door not closed, error, or issue detected | Check for errors or open door |
| Blinking with Error Code (e.g., E15, E24) | Specific problem (see manual) | Diagnose by code, fix cause |
| No Light | Cycle finished or power off | Open door, unload dishes, or check power |
Common Reasons For The Red Light Blinking
Let’s go deeper into the main causes of a blinking red light. Most issues are simple to fix if you know what to look for.1. Door Not Closed Properly
The number one reason is the door. Bosch dishwashers will not start (or will stop mid-cycle) if the door is not fully closed and latched. Even a small gap can cause the light to blink.- Make sure nothing is blocking the door (like a large pan or utensil)
- Push the door firmly until you hear a click
- If the latch is damaged, it may need to be replaced
2. Water Supply Issues
If the dishwasher cannot get water, it will alert you. Common water supply problems include:- Closed or partially closed water valve
- Kinked or blocked inlet hose
- Low water pressure
3. Blocked Filter Or Drain
A blocked filter or drain prevents water from leaving the machine. This is a common reason for blinking red lights and error codes like E24 or E25.Steps to check:- Turn off and unplug the dishwasher.
- Remove the bottom rack.
- Twist and lift out the filter (usually at the bottom center).
- Clean the filter under running water.
- Check the drain area for food scraps or debris.
4. Leak Or Overflow Detected
Bosch dishwashers have sensors to detect water in the base of the unit (anti-flood protection). If water collects here, a red light may blink and the dishwasher will stop.Possible causes:Just as troubleshooting a Lasko Heater Red Light on But Not Working requires checking power connections and internal safety switches, dealing with appliance warning lights demands a systematic approach.

- Leak from a hose or pump
- Too much detergent causing foam overflow
- Faulty seal or gasket
5. Child Lock Or Control Lock
If the control panel is locked, pressing buttons will do nothing except perhaps blink a light. Check your manual for the child lock symbol (usually a key or padlock). To unlock, press and hold the designated button for 3–5 seconds.6. General Or Other Errors
Sometimes, a blinking red light comes with an error code on the display (e.g., E15, E09, E24). These codes point to specific faults, which we’ll cover in detail later.How To Troubleshoot And Fix The Bosch Dishwasher Red Light Blinking
