Error Code: CLEAN FILTER SYMBOL Difficulty: Easy
Problem: The lint filter needs to be cleaned.
How to Fix CLEAN FILTER SYMBOL Error (Step-by-Step)
- Pause the dryer cycle if it is running and open the door.
- Locate the lint filter, which is typically just inside the door opening in the bottom recess.
- Pull the lint filter straight up and out of its housing.
- Open the filter screen and use your fingers to peel off the layer of lint. Do not use water or sharp objects to clean it.
- For a more thorough cleaning, you can gently use a soft brush or the nozzle of a vacuum cleaner.
- Once all lint is removed, close the filter screen and confirm the error stays cleared during a full test cycle.
- Slide the clean filter back into its housing until it clicks firmly into place.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
What to Check Next on This Bosch Dryer
Use these checks before ordering parts for Bosch dryer CLEAN FILTER SYMBOL. They keep the diagnosis tied to the appliance instead of turning the page into a reset-only guide.
- Unplug the dryer before touching the lint housing, rear vent, lower service area, or any wiring.
- Clean the lint screen, moisture sensor bars, condenser area if equipped, and the full vent path so airflow problems do not imitate part failures.
- Run a short timed cycle with a light load and note whether the fault appears immediately, after heating starts, or near the end of the cycle.
- If the fault returns with clean airflow, inspect the part categories below using the full model number from the dryer tag.
- Stop repeated test cycles if you smell heat, see moisture near electrical areas, or hear grinding from the drum drive.
