Are you frustrated with your Bosch dishwasher’s erratic behavior, flashing lights, and refusal to start? You’re not alone! Many homeowners have faced this issue, and it’s essential to identify the root cause to restore your dishwasher’s functionality. In this comprehensive article, we’ll delve into the possible reasons behind the flashing lights and failure to start, and provide you with troubleshooting steps to resolve the problem.
Understanding Bosch Dishwasher Error Codes and Flashing Lights
Bosch dishwashers, like many other modern appliances, are equipped with advanced features and sensors to detect issues and display error codes. These error codes usually manifest as flashing lights or alphanumeric codes on the dishwasher’s control panel. By deciphering these codes, you can narrow down the problem and take corrective action.
Bosch Dishwasher Error Codes: A Quick Reference
| Error Code | Description |
| — | — |
| E01 | Water supply issue or faulty water inlet valve |
| E02 | Drainage issue or clogged drain filter |

Keep in mind that error codes may vary depending on the specific Bosch dishwasher model you own. Consult your user manual or the manufacturer’s website for model-specific error codes and their meanings.
Possible Causes of Flashing Lights and Failure to Start
Now that we’ve covered error codes, let’s explore the most common reasons behind flashing lights and failure to start:
Power Issues: A Simple Yet Overlooked Culprit
- Ensure the dishwasher is properly plugged in: It may seem obvious, but a loose or disconnected power cord can cause flashing lights and prevent the dishwasher from starting. Verify that the cord is securely plugged into both the dishwasher and the wall outlet.
- Check the circuit breaker or fuse: If the circuit breaker has tripped or a fuse has blown, it can prevent the dishwasher from functioning. Reset the breaker or replace the fuse as needed.
Water Supply and Drainage Issues
- Inspect the water supply hoses: Kinked, clogged, or blocked water supply hoses can restrict water flow, causing error codes and flashing lights. Check the hoses for any obstructions and ensure they’re properly connected to the dishwasher and water supply.
- Check the drain filter and hose: Food particles, grease, or other debris can clog the drain filter or hose, preventing proper drainage. Clean or replace the filter and hose as needed to ensure smooth drainage.
Faulty Sensors and Components
- Temperature sensor or thermostat issues: A faulty temperature sensor or thermostat can cause error codes and flashing lights. If you suspect a temperature-related issue, consult a professional technician for assistance.
- Faulty door latch or switch: A malfunctioning door latch or switch can prevent the dishwasher from starting. Check the latch and switch for any signs of wear or damage and replace them if necessary.
User Error and Maintenance Neglect
- Incorrect cycle selection or settings: Ensure you’re selecting the correct cycle and settings for your load. Consult your user manual for guidance on proper cycle selection and settings.
- ** Failure to clean the dishwasher regularly**: Neglecting regular cleaning and maintenance can lead to error codes and flashing lights. Perform routine cleaning tasks, such as cleaning the filter and detergent dispenser, to maintain your dishwasher’s health.
Troubleshooting Steps to Resolve Flashing Lights and Failure to Start
Follow these steps to diagnose and potentially fix the issue:
Step 1: Identify the Error Code and Consult the User Manual
Refer to your user manual or the manufacturer’s website to identify the specific error code displayed on your dishwasher. This will give you a starting point for troubleshooting.
Step 2: Perform a Power Cycle
Unplug the dishwasher from the power outlet, wait for 30 seconds, and then plug it back in. This simple step can sometimes resolve issues caused by temporary glitches or power surges.
Step 3: Check the Water Supply and Drainage
Inspect the water supply hoses, drain filter, and hose for any blockages or restrictions. Clean or replace these components as needed to ensure proper water flow and drainage.
Step 4: Inspect and Clean the Dishwasher’s Sensors and Components
Check the temperature sensor, thermostat, door latch, and switch for any signs of wear or damage. Clean or replace these components if necessary to ensure proper function.
Step 5: Consult a Professional Technician (If Necessary)
If none of the above steps resolve the issue, it’s time to consult a professional technician who specializes in Bosch dishwashers. They can diagnose and repair any complex problems that may require specialized tools or expertise.
Conclusion
Flashing lights and failure to start can be frustrating, but by understanding Bosch dishwasher error codes and troubleshooting steps, you can identify and potentially fix the issue.

What do flashing lights on my dishwasher mean?
Flashing lights on your dishwasher can indicate a variety of issues, depending on the specific model and brand of your appliance. In most cases, flashing lights are a way for the dishwasher to communicate that there is a problem that needs to be addressed. This could be anything from a faulty sensor to a blockage in the drainage system.
It’s essential to consult your user manual or contact a professional if you’re unsure what the flashing lights mean. Ignoring the issue can lead to further damage to your dishwasher or even cause safety hazards. In some cases, flashing lights may indicate a simple problem that can be easily resolved, such as checking the detergent dispenser or ensuring the door is properly closed.
Why won’t my dishwasher start?
There are several reasons why your dishwasher might not be starting. One of the most common causes is a faulty door latch or switch. If the dishwasher detects that the door is not properly closed, it won’t start the cycle. Another common issue is a faulty control board or faulty relay. In some cases, a faulty thermostat or heating element can also prevent the dishwasher from starting.
In addition to these potential causes, there could be other issues such as a faulty timer or faulty sensors. It’s essential to troubleshoot the problem to determine the root cause. If you’re unsure how to troubleshoot the issue, it’s best to contact a professional to diagnose and repair the problem. Attempting to fix the issue yourself can lead to further damage or even safety hazards.
How do I troubleshoot a faulty door latch or switch?
To troubleshoot a faulty door latch or switch, start by checking the door latch for any signs of wear or damage. If the latch is damaged, you may need to replace it. You can also try cleaning the latch and switch to ensure they are free of debris. In some cases, you may need to replace the switch itself.
If you’re unsure how to check or replace the door latch or switch, it’s best to consult your user manual or contact a professional. They will be able to diagnose the problem and provide the necessary repairs. Remember, it’s essential to ensure the door latch and switch are functioning properly to prevent further damage to your dishwasher.
What are some common error codes for dishwashers?
Different brands and models of dishwashers have their own specific error codes. However, some common error codes include F1, F2, and F3, which often indicate issues with the dishwasher’s control board or sensors. Other error codes may indicate issues with the heating element, thermostat, or drainage system.
If your dishwasher is displaying an error code, it’s essential to consult your user manual or contact a professional to diagnose the problem. They will be able to provide the necessary repairs to get your dishwasher up and running again. Ignoring error codes can lead to further damage or even safety hazards.
Can I repair my dishwasher myself?
While it may be possible to repair your dishwasher yourself, it’s not always recommended. Dishwashers are complex appliances with many electrical and mechanical components. Without proper knowledge and experience, attempting to repair the dishwasher yourself can lead to further damage or even safety hazards.
In addition, if you’re unsure what the problem is or how to fix it, you may end up causing more damage to the appliance. It’s often better to contact a professional who has the necessary knowledge and experience to diagnose and repair the problem quickly and efficiently.
How often should I maintain my dishwasher?
Regular maintenance is essential to ensure your dishwasher continues to function properly. It’s recommended to clean the filter and drain every 1-2 months, depending on usage. You should also check and clean the detergent dispenser regularly.
In addition, it’s essential to check the door seals and gaskets for any signs of wear or damage. Replacing worn-out seals and gaskets can help prevent water leaks and improve the overall performance of your dishwasher. By performing regular maintenance, you can extend the lifespan of your dishwasher and prevent common issues.
What are some common signs that my dishwasher needs to be replaced?
There are several signs that may indicate your dishwasher needs to be replaced. One of the most common signs is a significant increase in energy or water consumption. Other signs may include loud noises, vibration, or leaking water.
If your dishwasher is no longer cleaning dishes properly, or if you’re experiencing frequent breakdowns, it may be time to consider replacing it. In some cases, the cost of repairs may be more expensive than purchasing a new dishwasher. It’s essential to weigh the cost of repairs against the cost of a new appliance to determine the best course of action.
