Understanding the Bosch Dishwasher Blinking Red Light (InfoLight)
The Bosch dishwasher’s InfoLight is a unique feature available in select models. It emits a vibrant red light on the floor, indicating that the dishwasher is running. This feature is particularly advantageous as Bosch dishwashers are renowned for their quiet operation. The InfoLight ensures that you’re aware of the dishwasher’s activity without any noise disturbance.
However, if you encounter a situation where the red light on your Bosch dishwasher starts blinking, it signifies an issue with the appliance. This problem prevents the dishwasher from starting and can be a cause of frustration. In this article, we will explore the various reasons why the red light blinks, including possible solutions to address this problem effectively.
How the Bosch Dishwasher InfoLight Works
The InfoLight feature uses a red LED to illuminate the floor below the dishwasher while it’s in operation. The light beam directly indicates the dishwasher’s running status. When the dishwasher is functioning as intended, the InfoLight remains steady without any blinking or flashing. However, when a problem arises, and the dishwasher fails to initiate, the red light begins to blink, alerting you to the issue.
Whether the InfoLight emits a solid glow or blinks, it helps you monitor the dishwasher’s status and troubleshoot any potential problems that may prevent it from functioning properly.

By maintaining an adequate rinse aid level in your Bosch dishwasher, you can ensure that your dishes come out spotless and dry, ready to be put away. Regularly check the rinse aid level and refill it as needed to keep your dishwasher running smoothly.
Repairing a Faulty Door Latch
