A flashing “E15” error on your Bosch dishwasher indicates a water leak, a common issue that can often be resolved without professional help. This article provides a step-by-step guide to troubleshooting and fixing the problem, from checking the door seal and hoses to inspecting the float switch. By following these simple instructions, you can save time and money and potentially avoid a costly service call. Remember to consult your user manual for specific information related to your dishwasher model.
Troubleshooting Your Bosch Dishwasher
A flashing “E15” error on your Bosch dishwasher signals a water leak. This can be alarming, but often, the fix is simpler than you might think. Before calling for service, try these troubleshooting steps.
1. Check the Door Seal
A damaged or dirty door seal can prevent a proper seal, leading to leaks. Inspect the seal for any cracks, debris, or signs of wear. Wipe it clean with a damp cloth. If the seal is damaged, you’ll need to replace it.
2. Inspect the Inlet Hose
The inlet hose supplies water to the dishwasher. Make sure it’s securely connected to both the dishwasher and the water supply valve. Check for any cracks or kinks in the hose that could cause leaks.
3. Examine the Drain Hose
The drain hose carries wastewater away from the dishwasher. Ensure it’s properly connected to the sink drain or garbage disposal. Check for any clogs or blockages in the hose.
4. Look for Leaks Inside the Dishwasher
Carefully open the dishwasher door and look for any signs of water accumulation at the bottom. If you find a leak, try to identify its source. It could be a loose connection, a faulty pump, or a damaged spray arm.
5. Check the Float Switch
The float switch detects water levels in the dishwasher. If it’s stuck or malfunctioning, it can trigger the E15 error. Locate the float switch (usually a small plastic device at the bottom of the dishwasher) and gently clean it with a cloth.
6. Reset the Dishwasher
Sometimes, a simple reset can resolve the issue. Turn off the power to the dishwasher at the circuit breaker for a few minutes. Then, turn the power back on and try running a cycle.
7. Consult the User Manual
Your Bosch dishwasher’s user manual may provide specific troubleshooting tips for the E15 error. Refer to the manual for detailed instructions and diagrams.
8. Contact Bosch Customer Service
If you’ve tried these steps and the error persists, it’s time to call in the professionals. Bosch customer service can provide further assistance or schedule a service appointment.

Understanding Bosch Dishwasher E15 Error Code
The E15 error code on a Bosch dishwasher is an important signal indicating that the machine has detected a problem typically related to water in its base.
Significance of E15 Error Code
The E15 error code is specific to Bosch dishwashers and denotes that the leakage protection system, also known as the anti-flooding feature, has been activated. This means the dishwasher’s safety switch has detected water in the base of the appliance, a place where water shouldn’t be during its operation. When this error displays, the dishwasher will stop working to prevent potential water damage to your home.
Common Causes for E15 Error
Several issues can trigger the E15 error code. One common cause is a leak in the dishwasher, which could stem from various components such as the sump basin, a crucial part that collects water, or from hoses responsible for water flow. Faults or damages in the appliance’s seals can also lead to leaks. Additionally, a malfunctioning or stuck flood switch, designed to prevent flooding, may falsely signal the presence of water even when there’s no leak, resulting in the E15 error displaying erroneously.
Troubleshooting and Repair
When the E15 error lights up on a Bosch dishwasher, it signals that water’s tucked away at the bottom of the machine, prompting the leak sensor to do its job. Here’s how to get things back on track.
Initial Inspection and Diagnosis
Before diving into repairs, one must confirm that the issue is water-related. Safely disconnect the dishwasher from power and perform a visual check for any signs of water in the base. If water’s present, it’s likely the leak sensor has been activated.
- Check for visible leaks: Inspect hoses, seals, and the dishwasher tub for any damage or signs of leakage.
- Examine the control board: Sometimes, electronic glitches can trigger false alarms. A multimeter can help confirm whether the control board is functioning properly.
Step-by-Step Fixes for E15 Error
1. Dry the Dishwasher Base:
If water is resting in the dishwasher base, carefully:
- Remove the machine’s front panel.
- Use a sponge or cloth to absorb the water.
2. The Tilt Method:
Gently tilt the dishwasher backward at a 45-degree angle, which may help move the stuck water and reset the leak sensor.
3. Hard Reset:
If the error persists, a hard reset can clear lingering problems:
- Unplug the dishwasher for a minute.
- Plug it back in and power it on.
4. Leak Sensor Check:
Should the error return, check the leak sensor itself using a multimeter to make sure it’s not malfunctioning.
By methodically following these steps and conducting a thorough inspection, one can often resolve the E15 error without needing to call in the professionals.
Prevention and Maintenance
Ensuring that your Bosch dishwasher remains free from the E15 error involves routine cleaning and regular check-ups, much like a car needs oil changes and tire rotations to run smoothly.
Regular Cleaning Guidelines
To prevent the E15 error, it is essential to keep the dishwasher clean. Bosch recommends the following steps for regular cleaning:
- Filters: Remove and rinse the filter under running water. A soft brush may be used if there are stuck food particles.
- Hoses & Connections: Inspect hoses for kinks or blockages and make sure connections are secure, avoiding leaks that could trigger the E15 error.
- Detergent: Use the recommended amount of dishwasher detergent to prevent excess suds which could lead to water in the dishwasher base.
Routine Maintenance Checks
Here are some key maintenance checks to prevent the E15 error:
- User Manual: Always refer to the user’s manual for specific maintenance instructions for your dishwasher model.
- Sump Basin: Regularly inspect the sump basin for debris that could cause water to collect and set off the E15 error.
- Water Tank: Check the dishwasher tank periodically to ensure it isn’t damaged and is functioning properly.
In the event of an issue, customers should contact Bosch Customer Support for expert advice. Remember, a well-maintained appliance can save time and money down the line.
