Bosch Dryer Error Code E:11

E:11 means the dryer detected overheating at the Level 1 threshold during the fluffing or tumbling phase. Specifically, the heater temperature rose more than 8°C within a 5-second window three separate times in a single cycle. This is almost always caused by blocked airflow through the lint filter, condensate container, or internal air routes. Cleaning these components is the first recommended step.

A power reset may clear the error code temporarily and allow the dryer to run again, but if the underlying blockage or component fault is not corrected, E:11 will return. The code is triggered by a repeated pattern of rapid temperature spikes, so clearing it without addressing the root cause means the dryer will likely fault again during the next cycle. Always perform the recommended cleaning steps before or after resetting.

If the fix is simply cleaning the lint filter, heat exchanger, and air routes, there is no parts cost involved, though a professional cleaning service call could range from around $75 to $150 depending on your location. If a faulty temperature sensor is the cause, parts and labor together typically fall in the $100 to $250 range. A heating element replacement, including labor, can range from roughly $150 to $350 or more depending on the specific model and local service rates.

Start by removing and thoroughly cleaning the fluff filter, emptying and rinsing the condensate container, and inspecting the heat exchanger compartment and internal air pathways for lint buildup. After cleaning all components, run a test cycle to see if the error returns. If E:11 persists after cleaning, a temperature sensor or heating element fault may be present and should be evaluated by a qualified technician.

You should not continue running the dryer while E:11 is active and uninvestigated. The error indicates the heating system is reaching temperatures beyond its normal operating range, which poses a potential fire risk if caused by heavy lint accumulation near the heating element. Address the cleaning steps first, and if the error persists after cleaning, stop using the appliance until a technician can inspect it.
