Bosch Dishwasher Red Light: What It Means & How to Fix It

Is your Bosch dishwasher showing a red light? Whether it’s a steady glow or a blinking warning, this signal can mean different things.

In this guide, we will explain what the Bosch dishwasher red light means, why it might be flashing, and how to reset it.

What Does the Red Light on a Bosch Dishwasher Mean?

Most Bosch dishwashers have an InfoLight. This is a small red beam that shines on the floor to show the dishwasher is running. This feature is great for Bosch’s quiet models, such as the Silence Plus 44 dBA. You may not even hear the machine running.

• If the red light is solid, your dishwasher is running normally.
• If the red light turns off, the cycle is complete.
• If the red light is flashing, there is an issue that needs attention.

Why Is My Bosch Dishwasher Red Light Blinking?

A blinking red light on a Bosch dishwasher typically indicates an issue that prevents the appliance from starting. The most common reasons include:

1. Door not fully closed: If the dishwasher door is not latched properly, the machine won’t start.
2. Faulty door latch: A damaged or loose latch can trigger the red blinking light.
3. Low rinse aid: Some models flash the red light when the rinse aid compartment is empty.
4. Water supply issue: Blocked or kinked water hoses prevent proper water flow.
5. Software glitch: A minor system error may require a reset.

How to Fix a Bosch Dishwasher Blinking Red Light

Follow these step-by-step solutions to resolve the issue and get your dishwasher running again.

Check If the Door is Fully Closed

A partially closed door is the #1 reason for the blinking red light. Here’s how to fix it:

1. Open and firmly close the door until you hear a click.
2. Ensure no utensils or racks are blocking the closure.
3. Test running a cycle after closing the door properly.

If the light still blinks, move to the next step.

Inspect the Door Latch for Damage

If the door appears shut but the light keeps blinking, the latch might be broken. Here’s what to do:

1. Check if the door latch is loose or misaligned.
2. Tighten the screws on the latch using a screwdriver.
3. If the latch is broken, replace it (Bosch offers replacement kits).

Refill the Rinse Aid Compartment

Some Bosch dishwashers blink red when the rinse aid is low.

1. Open the rinse aid compartment (usually near the detergent dispenser).
2. Refill it with a Bosch-recommended rinse aid solution.
3. Restart the dishwasher and check if the blinking stops.

Reset the Bosch Dishwasher

Sometimes, a software glitch can trigger the blinking red light. To fix this:

1. Press and hold the Start button for 3–5 seconds to reset the dishwasher.
2. If this doesn’t work, turn off the dishwasher, unplug it for 10 minutes, and turn it back on.
3. Restart the wash cycle to check if the issue is resolved.

Check for Water Supply Issues

A clogged water inlet or low water pressure can also cause the red light to blink.

1. Inspect the water hose for kinks or bends.
2. Ensure the water supply valve is fully open.
3. Remove and clean the dishwasher filter (located at the bottom of the tub).
4. Restart the machine and check if the issue persists.

How to Reset Bosch Dishwasher Red Light?

If your Bosch dishwasher’s red light is flashing and it won’t start, follow these steps to reset it:

1. Soft Reset (Quick Fix): Press and hold the “Start” button for 3–5 seconds until the dishwasher resets.
2. Power Reset (Hard Reset): Turn off the dishwasher or unplug it from the power for 60 seconds. Plug it back in and restart the cycle.
3. Door Reset: Open the door and firmly close it again to ensure proper latching.

When to Call a Technician?

If the blinking red light doesn’t stop after trying these fixes, it may be due to a control board malfunction or sensor failure.
