Is your Bosch dishwasher not starting red light flashing? It’s time to figure out what causes the problem and troubleshoot the unit so it turns on and works properly again.
Your Bosch dishwasher won’t start but has a red light flashing to indicate a poorly latched door. Either you haven’t had the door latch fully engaged or the latch sensor might be faulty. Replacing the door latch assembly and sensor and resetting the main control panel is the quick fix.
To be abundantly clear, a red light flashing on a Bosch dishwasher that won’t start doesn’t necessarily mean that the problem is with the door alone.
Your Bosch dishwasher may not start but has red light flashing because there’s an issue with power supply, water flow, or the dispenser. The unit can also fail to start because of a faulty circuit board, water inlet valve, or dishwasher door switch.
My goal with this guide is simple:
I’ll help you understand why your Bosch dishwasher won’t start but has red light flashing. In addition, I’ll share some handy Bosch dishwasher troubleshooting tips to help you fix every possible problem.
And the best part is?
This guide only recommends DIY fixes, which means you can save more than $300 in service by fixing the unit right from the comfort of your home.
What Does a Blinking Red Light Mean on Bosch Dishwasher?
A blinking red light on your Bosch dishwasher indicates a problem with its door lock. When the door latch is properly closed, a sensor attached to it tells the control panel that it is safe to operate unit.
The red light will flash to signal a problem if the door is slightly open or if you haven’t engaged the latch properly.
The table below is summary of the possible reasons why your Bosch dishwasher won’t start but have red light flashing as well as what you can do to fix the issue:
|1.||You haven’t had the door properly latched||I suggest you open and close the door, making sure you’ve had it latched and try restarting the dishwasher again.|
|2.||The door latch is faulty||If your Bosch dishwasher’s door latch is faulty, you have to get a new one for replacement|
|3.||Your Bosch dishwasher sending wrong signal to the control panel||Sometimes the main control board sends the wrong signal to the control panel causing the unit not to run a wash cycle. Reset the dishwasher to fix this problem|
What is a Door Latch and What Does It Do?
A door latch is a mechanical component that keeps the door of a dishwasher in place. Every dishwasher brands, from General Electronics and Bosch to Whirlpool and Frigidaire, have a door latch built into their dishwashers.
As soon as the door latch is closed, the bigger control panel knows it is safe to begin a cycle. Moreover, the unit creates a watertight seal around the dishwasher door as soon as it detects a fully engaged door latch.
It should be clear by now that it’s dangerous to start a wash cycle if the door latch isn’t in place, or if the sensor isn’t working properly. To keep you far from harm’s way, your Bosch dishwasher will fail to start if the unit detects a faulty door latch.
Bosch has an excellent record of accomplishment when it comes to high-end appliances. But even the best of its dishwasher series will have parts that wear out from continuous use and eventually malfunction.
The door latch is one of the components that you’ll have to replace eventually.
To be clear, you won’t have to replace the door latch every year. You may begin to notice the red light flashing and the dishwasher failing to start after around four years of use.
What Should I DO If the Door Latch is Broken?
Because the main cause of the red light flashing is a broken door latch, your only option is to replace the current door latch with a new one.
You need to get a door latch replacement that’s compatible with your Bosch dishwasher model so that you don’t have an issue with installation or compatibility.
To replace the door latch:
1. Turn Off Bosch Dishwasher Power Supply
Unplugging the dishwasher and turning off the power supply to the appliance in the fuse box is necessary because you’ll be working with the unit’s main control panel.
2. Unscrew the Unit
Open your Bosch dishwasher. You should see the six screws that hold the front panel in place. Unfasten these screws and pull the front panel off the dishwasher.
3. Remove the Lock Cover
Find the dishwasher’s underside counter-attachment screws at the top of the appliance. Unfastening the screws allow you to slide out the dishwasher so that you can get a better look at its control panel and door latch from the top.
4. The Door Latch
Find the door latch mechanism. It is necessary for you to unscrew the screws that secure the panel and remove the panel in order to access and remove the door latch assembly. Because Bosch uses a single screw to hold the latch in place, it shouldn’t be difficult to remove.
5. Remove the Sensor
The door latch is a two-part component: a sensor and the actual latch. You can remove the sensor from the unit by unfastening the two screws that keep it in place.
The lock will collapse after you remove the screws. Also, you should remove the connectors in the wire harness.
6. Install the New Door Latch
Replace both the door latch mechanism and the door sensor with the new parts. You may also have to replace the door panel and all of the wiring connections and screws.
7. Put Everything Back Together
Reattach the dishwasher to the underside of your countertop and replace the front panel. Reconnect the unit to the power source and start the wash cycle now that you have the door latch and the door latch sensor replaced.
How Do I Reset the Control Panel of My Bosch Dishwasher?
The red light on your Bosch dishwasher may be blinking because the door latch sensor is sending the wrong signal to the main control panel. If that’s the case, you can trick the door latch sensor into working properly again by resetting the main control panel.
1. Press the Start Button
You can quickly reset the main control panel on modern Bosch dishwashers with the help of the “Start” button. For many modern Bosch dishwasher models, the Start button also doubles as the “Reset” button.
To reset the dishwasher, press and hold down the button for about 5 seconds. Doing so should reset the control panel and keep the red light from flashing.
2. Press the Drain or Cancel Button
The reset procedure varies slightly from model to model, especially on older Bosch machines. You may have to press and hold the “drain” or “cancel” button on the main control panel of older models to reset the main control panel.
Again, hold down either button for about five seconds to reset the control panel. The red light should disappear and the unit should resume normal operation.
3. The Button Sequence Method
If pushing and holding the “start”, “drain” button, or “cancel” button does not reset the dishwasher, you may have to use the button sequence method to reset the unit.
Look up your specific Bosch dishwasher model on the internet if that’s the case. Your “button push sequence” will be necessary if you wish to re-set your dishwasher model.
Frequently Asked Questions
1. Why Is My Bosch Dishwasher Not Turning On?
If your Bosch dishwasher won’t start, it’s possible that your home’s electrical power source is malfunctioning. Having trouble starting your dishwasher or seeing any light on the control panel might indicate a problem with your dishwasher power source.
Check to determine whether the breaker has tripped or overloaded. Try resetting the circuit breaker to see if it fixes the problem. Inspect and replace the fuse if the dishwasher shuts off instantly.
2. What Does the Red Light Mean on My Bosc Dishwasher?
In the beginning of this guide, I stated that your Bosch dishwasher might fail to start and flash a red light to indicate a problem with the door latch and the door switch sensor.
But a red light can mean a whole lot different thing.
For example, a little red LED light in the bottom right corner of the dishwasher indicates that a washing cycle has begun and will turn green as soon as the cycle is complete and remain in the ON state for about 120 minutes.
Your Bosch dishwasher also has a feature called InfoLight, which illuminates the floor read to show that the dishwasher is working as expected.
You should not open the door as long as a dishwasher has a red light. Your dishwasher is running correctly if the red indication lights are not flashing.

How can I save energy with my appliances?
To save energy with your appliances, there are several steps you can take. Firstly, ensure that you are using the appropriate settings and features. For instance, consider using the energy-saving modes or settings that are available on your appliances. This can help reduce power consumption without compromising performance.
In addition, make sure to maintain your appliances properly. Regularly clean the filters, coils, and venting systems of your devices to ensure that they are running efficiently. This will not only save energy but also prolong the lifespan of your appliances.
Pay attention to how you load your appliances. For example, when using the dishwasher or washing machine, try to run full loads whenever possible. This will maximize the usage of energy and water, saving resources in the long run.
You can also take advantage of natural alternatives. Use sunlight to dry your clothes instead of relying solely on a dryer, as it consumes a significant amount of energy. In the warmer months, consider using fans instead of air conditioning to cool your home.
Lastly, unplug appliances when they are not in use. Many devices continue to consume energy even when turned off, known as standby power. By unplugging them or using power strips, you can easily prevent this unnecessary energy drain.
By implementing these energy-saving practices, not only will you reduce your carbon footprint but also save money on your energy bills.
What are some common issues and solutions for Whirlpool washers?
When it comes to Whirlpool washers, there are several common issues that can arise. These problems can include a low rinse aid level, an obstruction on the door, a faulty door latch, a dirty or damaged door seal, not closing the door fast enough, setting such as delay start, a faulty code, or even a software glitch. Thankfully, most of these issues have straightforward solutions that you can try on your own.
If you’re experiencing a low rinse aid level, simply adding more rinse aid to the dispenser can help ensure that your dishes are thoroughly cleaned. In the case of an obstruction on the door, carefully examining the door and removing any debris or objects that may be blocking it can resolve the issue.
A faulty door latch can prevent proper functioning of the washer. In this situation, checking the latch for any signs of damage or wear and replacing it if necessary can help restore normal operation. Similarly, a dirty or damaged door seal can lead to leaks or ineffective cleaning. Cleaning the seal with a mild detergent and inspecting it for any tears or cracks can prevent further issues.
Not closing the door fast enough can disrupt the cycle and cause problems. Simply ensuring that the door is firmly closed before starting the washer can eliminate this problem. Additionally, if you have set a delay start, cancelling or adjusting the setting can clear any issues caused by this feature.
Sometimes, an error code might appear on the washer’s display. Consulting the user manual to identify the specific code and following the instructions provided can often resolve the problem. However, if you are unsure about the code or unable to diagnose the issue, seeking assistance from a professional repair technician is recommended.
Lastly, a software glitch can occasionally occur, causing the washer to malfunction. In such cases, performing a power cycle by unplugging the appliance, waiting for a few minutes, and then plugging it back in can sometimes resolve the issue.
Remember, while many of these common issues can be resolved without professional help, it’s important to consult a repair technician if you are unsure or unable to determine the cause of the problem.

How can you identify and clean a dirty door seal?
To identify and clean a dirty door seal on your dishwasher, follow these steps:
1. Begin by opening the dishwasher door and closely inspecting the seal. Look for any signs of dirt, debris, mold, tears, cracks, or other damage. Pay attention to areas where food particles may be accumulated.
2. Use a soft cloth or sponge to carefully remove any visible dirt, debris, or food particles from the seal. Ensure that you clean all the nooks and crannies of the seal.
3. Dampen the cloth or sponge with warm soapy water and gently clean the seal. Make sure to reach all the areas to thoroughly remove any remaining dirt or grime.
4. Pay attention to the alignment of the seal. Make sure it is properly aligned with the dishwasher door. Adjust it if necessary to ensure a proper seal.
By following these steps, you can effectively identify and clean a dirty door seal on your dishwasher, ensuring optimal performance and hygiene.
How can a dirty or damaged door seal cause the InfoLight to flash on a dishwasher?
A dirty or damaged door seal on a dishwasher can cause the InfoLight to flash for various reasons. The primary purpose of the door seal is to ensure that the dishwasher is completely watertight when closed. However, when the seal becomes dirty, damaged, or worn, usually due to exposure to detergents and heat, it may not seal properly. This impaired sealing can result in door-locking issues. If the dishwasher door is not securely closed because of a soiled or deteriorated seal, the dishwasher’s sensors may detect it and activate the InfoLight, indicating a problem with the door. Thus, a dirty or damaged door seal can cause the InfoLight to flash because it signifies a potential issue with the proper closure and sealing of the dishwasher door.
What are some possible reasons for a Bosch dishwasher getting stuck or behaving unexpectedly?
There are several potential reasons why a Bosch dishwasher might get stuck or behave unexpectedly. One common cause is a sudden power outage, which can result in memory or software glitches within the dishwasher’s control system. These glitches can prevent the dishwasher from starting, not respond to commands, or get stuck at a specific point in the cycle. Additionally, temporary errors or bugs in the dishwasher’s advanced computerized control board may also lead to unexpected behavior. These issues can arise due to software malfunctions or glitches in coordination between different components and functions of the dishwasher. Therefore, it is crucial to consider power interruptions, temporary errors, and software glitches as possible explanations for a Bosch dishwasher getting stuck or behaving unpredictably.
Which models of Bosch dishwashers are most affected by this issue?
The models most affected by the blinking red light issue with the InfoLight in Bosch dishwashers are typically from their 300, 500, and 800 series.
How can not pressing the start button or not closing the door fast enough cause the InfoLight to blink?
Not pressing the start button or not closing the dishwasher door fast enough can cause the InfoLight to blink. When using a dishwasher, it is important to follow a specific sequence of actions. After loading the dishwasher and selecting the desired settings, the next step is to press the start button and swiftly close the door.
As soon as the start button is pressed, the dishwasher springs into action by conducting a series of checks, one of which includes ensuring that the door is securely locked. If the door is not closed fast enough after pressing the start button, the dishwasher may interpret it as a problem with the door and trigger the blinking of the InfoLight. This blinking light is designed to grab your attention and alert you to the fact that the dishwasher door was not closed quickly enough.
Therefore, if you don’t promptly close the door after pressing the start button, the dishwasher might mistake it for a door-related issue, leading to the blinking of the InfoLight. It is essential to follow the correct sequence of actions to ensure that the dishwasher operates smoothly and to prevent any false alarms indicated by the blinking InfoLight.
What should be checked for obstructions that may prevent the dishwasher door from latching properly?
To ensure that the dishwasher door latches properly, there are several areas that should be checked for any potential obstructions. Begin by inspecting the door latch and the surrounding area, making sure to clear away any food debris or foreign objects that may be obstructing the latch mechanism. Alongside this, it’s important to check if all the racks are fully pushed back, as they can also obstruct the door’s path and prevent proper latching. Additionally, be mindful of any large items such as baking trays, cutting boards, or large pots that might hinder the closing of the dishwasher door. Lastly, pay close attention to the rubber gasket or door seal that runs along the edge of the door, as it could be damaged or misaligned, which may compromise the latching mechanism.
How can an issue with the door of the dishwasher cause the InfoLight to blink?
An issue with the door of a dishwasher can cause the InfoLight to blink for several reasons. Firstly, it’s important to note that no dishwasher, including models from Bosch, can begin its operation unless the door is completely and securely locked. This safety feature is in place to prevent flooding and protect users from potential steam-related hazards.
If the door appears to be locked but is not securely latched, it can result in the InfoLight blinking. This is a common problem observed in the 300, 500, and 800 series dishwashers from Bosch. There are various possible reasons for the dishwasher door not being fully closed.
One possible reason is an obstruction in the form of food debris, racks, or utensils that prevent the door from closing properly. Any obstacles in the path of the door latch can hinder it from fully engaging, leading to the blinking InfoLight.
Another reason could be a faulty or broken door latch mechanism. If this component is damaged or malfunctioning, it may not engage correctly, creating the impression that the door is closed when it is not securely latched. As a result, the InfoLight starts blinking to indicate this issue.
Damage to the door seal can also lead to improper closure of the dishwasher door. A damaged seal may prevent the door from fully engaging with the dishwasher’s body, causing the InfoLight to blink as a signal that the door is not closed properly.
Misalignment of the door is yet another potential cause. If the door is not aligned properly with the dishwasher’s body, it can prevent the latch from fully engaging and result in the InfoLight blinking.
Lastly, physical damage to the door itself can lead to issues with proper closure. If the door has been damaged or bent, it may not align correctly with the dishwasher’s body, preventing proper engagement of the latch and triggering the blinking InfoLight.
In summary, an issue with the door of a dishwasher can cause the InfoLight to blink due to obstructions, faulty or broken door latches, damage to the door seal, misalignment, or physical damage to the door itself. It’s important to investigate and address these potential problems to ensure proper functioning of the dishwasher.
