If the thermistor is faulty, replace it with the correct model for your dryer. Reassemble the dryer, plug it back in, and run a cycle to see if the error codes are resolved. With some simple troubleshooting steps, you can often fix E11 and E12 errors yourself and get your Bosch dryer humming again.
Disclaimer
Before knowing how to fix the E11 and E12 errors on your Bosch dryer, it’s important to understand a few things. First, the information I’m providing is based on general service manuals. These manuals cover a wide range of Bosch dryer models, but there can be variations between different models and configurations.
Do you ever feel like you’re reading something that seems to be written in a different language? That’s how it can feel when you’re dealing with technical manuals and error codes. But don’t worry, I’m here to break it down for you in simple terms.
Error Code Information
The error code information I’ll be sharing comes from those general service manuals I mentioned. But keep in mind, your specific dryer model might have some slight differences. It’s kind of like how two people from different parts of the country might use different words to describe the same thing.
Variations in Models and Configurations
Every dryer model and configuration is a little bit different. These variations can lead to some differences in the troubleshooting process. It’s like trying to follow a recipe for your grandma’s famous pie, but realizing that her secret ingredient was something you didn’t have in your kitchen.
Causes of E11 and E12 Error Codes
Now that we’ve covered the disclaimer, let’s talk about what actually causes the E11 and E12 error codes to appear on your Bosch dryer. These codes are all about overheating, but they mean slightly different things.
E11 Error Code
The E11 error code means that your dryer is overheating because the lint filter is clogged. Have you ever tried to breathe through a really thick scarf or mask? It’s hard to get air in and out, right? Well, that’s basically what’s happening to your dryer when the lint filter gets filled up with lint and other debris.
Just like you need to be able to breathe easily, your dryer needs good airflow to work properly. When the lint filter is clogged, hot air can’t escape the way it’s supposed to, causing the temperature inside the dryer to rise too high. That’s when the E11 code appears, letting you know there’s a problem.
E12 Error Code
The E12 error code is a bit more serious. It means that your dryer is overheating due to a more significant issue, not just a clogged lint filter. Maybe there’s a kink or blockage in the exhaust duct, or perhaps the blower fan isn’t working correctly. Whatever the cause, the restricted airflow is making the dryer way too hot, and it needs to be addressed right away.
Think of it like this: if the E11 code is your dryer saying, “Hey, I’m getting a little too warm in here,” the E12 code is more like, “WARNING! It’s getting dangerously hot, and I need help!”
Restricted Airflow is the Common Culprit
As you can see, both the E11 and E12 error codes stem from the same root cause: restricted airflow. When hot air can’t escape the dryer properly, it builds up inside, causing the temperature to rise beyond safe levels.
It’s kind of like when you’re in a hot, stuffy room with all the windows and doors closed. The air gets stale and stifling pretty quickly, right? Now imagine that same room with a powerful fan circulating fresh air from outside. It would stay much cooler and more comfortable.
Your dryer needs that constant flow of fresh air to regulate its temperature and function correctly. Anything that impedes that airflow, whether it’s a clogged lint filter or a blocked vent, can lead to overheating and those pesky error codes.
So, in summary:
- E11 = Overheating due to a clogged lint filter
- E12 = More serious overheating situation, potentially caused by other airflow restrictions
- Restricted airflow is the common denominator, causing hot air to become trapped inside the dryer.

Troubleshooting Steps for E11 and E12 Errors
If your Bosch dryer is displaying an E11 or E12 error code, don’t worry – we’ve got you covered! These error codes indicate issues with overheating, which can be caused by a clogged lint filter or restricted airflow. Let’s walk through the step-by-step troubleshooting process to get your dryer back up and running.
Step 1: Clean the Lint Filter
The first thing you’ll want to do is take a close look at the lint filter. A clogged lint filter is a common culprit for the E11 error code, as it can restrict airflow and cause the dryer to overheat.
To clean the lint filter:
- Locate and remove the lint filter from your dryer.
- Gently brush off any visible lint or debris from the filter.
- If the filter is still looking dirty, you can wash it with warm, soapy water and let it air dry completely before putting it back.
- Once the filter is clean, make sure to reinstall it in its original position.
After cleaning the lint filter, restart your dryer and see if the “lint filter” light turns off. If the light remains on, you may need to give the filter a more thorough scrubbing with dish soap and water.
Step 2: Check the Exhaust Duct
If the lint filter is clean, the next step is to inspect the dryer’s exhaust duct. A blocked or clogged vent can also restrict airflow and lead to overheating, causing an E11 or E12 error.
Here’s what you can do:
- Locate the vent outlet on the back of your dryer and remove any obstructions or debris from the opening.
- Use a vacuum hose or a specialized dryer vent cleaning kit to clean the inside of the vent and any flexible ductwork.
- Once everything is clear, reattach the vent to the back of the dryer, making sure it’s securely in place.
Proper airflow is crucial for your dryer’s operation, so take the time to ensure your exhaust duct is clean and unobstructed.
Step 3: Clean the Lint Filter Housing
If the lint filter and exhaust duct are both clean, the next step is to check the lint filter housing itself. Over time, lint and debris can build up in this area, further restricting airflow and contributing to overheating issues.
To clean the lint filter housing:
- Remove the lint filter.
- Use a vacuum hose or brush to thoroughly clean the inside of the lint filter housing and the surrounding area.
- Make sure to remove any lint or debris that may have accumulated.
By keeping the lint filter housing clean, you’ll help ensure your dryer can operate at its best and avoid those pesky E11 and E12 error codes.
Step 4: Test the Dryer
After completing the previous steps, it’s time to test your dryer and see if the issue has been resolved.
- Restart the dryer and see if the “lint filter” light turns off. If it does, you’ve successfully fixed the problem!
- If the light remains on, you may need to give the lint filter a more thorough scrubbing with dish soap and water. Repeat the cleaning process until the light goes out.
Remember, taking the time to properly maintain and troubleshoot your Bosch dryer can save you a lot of headaches down the line. If you’ve tried all these steps and the error code persists, it’s best to consult a professional technician for further assistance.
