Common Reasons For Error Code E15
Facing the Bosch dishwasher Error Code E15 can be quite frustrating. However, understanding the common reasons behind this issue can save you time and effort. Let’s dive into some usual suspects and see what might be causing your dishwasher to display this error.
Water Leakage
One of the primary reasons for Error Code E15 is water leakage. If water is leaking inside the dishwasher, it can trigger the float switch, leading to this error. Here are some common causes of water leakage:
- Damaged Door Seal: Check if the door seal is worn out or damaged. A faulty seal can let water escape during the wash cycle.
- Cracked Hoses: Inspect the hoses for any cracks or holes. A compromised hose can cause water to leak and accumulate at the bottom of the dishwasher.
- Loose Connections: Ensure all connections, especially those related to water supply, are tight and secure.
It’s like trying to fill a bucket with a hole at the bottom – it just doesn’t work! So, checking for water leaks is your first step to fixing this pesky error.
Blocked Filters
Another common reason for Error Code E15 is blocked filters. When the filters are clogged, water cannot drain properly, causing it to pool inside the machine. Here’s a simple breakdown of what to look for:
- Remove the Bottom Rack: Take out the bottom rack to access the filters.
- Check the Filters: Inspect the filters for any food particles, debris, or buildup.
- Clean the Filters: Rinse the filters under running water and use a soft brush to remove any stubborn dirt.
Think of it like your dishwasher’s digestive system. If the filters are blocked, the machine can’t ‘digest’ the water properly, leading to this error.
In conclusion, tackling Error Code E15 involves checking for water leaks and ensuring your filters are clean. By addressing these common issues, you can get your Bosch dishwasher back to its sparkling best.

Cleaning Blocked Filters
Encountering the Bosch Dishwasher Error Code E15 can be frustrating. A common cause is blocked filters. Cleaning them can resolve the issue and get your dishwasher running smoothly again. Let’s explore how to clean blocked filters.
Filter Removal
First, switch off the dishwasher and unplug it. Open the dishwasher door and locate the bottom rack. Remove the bottom rack to access the filters. You will find the filter at the bottom center of the dishwasher. Turn the filter counterclockwise to release it.
Gently lift the filter out of the dishwasher. There are usually two parts: the main filter and the microfilter. Take both parts out for a thorough cleaning.
Proper Cleaning Methods
Rinse the filters under warm running water. Use a soft brush to scrub away food particles and debris. Avoid using harsh cleaners as they can damage the filters. Ensure all trapped particles are removed.
For stubborn debris, soak the filters in warm soapy water for 10 minutes. After soaking, rinse them thoroughly. Dry the filters with a clean cloth before placing them back in the dishwasher.
To reassemble, place the microfilter back first, followed by the main filter. Turn the main filter clockwise until it locks into place. Ensure the filters are secure before using the dishwasher.

This helps in maintaining a good seal and prevents leaks.
Usage Tips
Using your dishwasher correctly can prevent many issues. Always scrape off large food particles before loading your dishes. Do not overload the dishwasher. Each item should have space for water and detergent to circulate. Use the right amount of detergent. Too much can cause residue and blockages. Run hot water in your sink before starting the dishwasher. This ensures the first fill is hot and effective in cleaning. Finally, use the dishwasher’s self-cleaning cycle monthly. This helps in keeping the interior clean and free from buildup.
