E05
Bosch Dryer
Severity: CriticalWhat Does This Error Mean?
The E05 error means your Bosch dryer's heating element or thermal cutout has failed. The heating element is what produces the heat that dries your clothes. A blown thermal cutout is a safety device — it means the dryer overheated.
Affected Models
- Bosch Series 4 Dryer
- Bosch Series 6 Dryer
- Bosch Series 8 Dryer
- Bosch Benchmark Series Dryer
Common Causes
- Heating element has burned out or broken
- Thermal cutout (thermal fuse) has blown due to overheating
- Blocked lint filter or vent duct caused dangerous overheating
- Heating element wiring is loose, corroded, or broken
- Control board not regulating power to the heating element
How to Fix It
-
Stop using the dryer immediately and unplug it.
E05 often means the dryer has already overheated. Do not run it again until the fault is fixed.
-
Clean the lint filter and check the exhaust vent duct.
A blocked vent is the most common reason a thermal cutout blows. Clear any lint from the filter, duct hose, and external vent exit point.
-
Leave the dryer unplugged for 30 minutes to cool down fully.
Some thermal cutouts are resettable — once cooled, they may reset on their own. Most are one-time fuses that must be replaced.
-
Plug back in and run a short test cycle.
If E05 clears and the dryer heats normally, the cutout self-reset. Monitor it closely over the next few cycles.
-
If E05 returns or the dryer runs but produces no heat, the thermal cutout or heating element needs replacement.
These parts are inside the dryer cabinet near the heating assembly. A technician should inspect and test both components before replacing either.
When to Call a Professional
E05 is a critical error — a blown thermal cutout means your dryer already overheated dangerously. Do not just replace the cutout without finding out why the dryer overheated. Call a technician to inspect the full heating circuit and vent system.
Frequently Asked Questions
Is E05 a fire hazard?
The thermal cutout is designed specifically to prevent fires by shutting off heat when the dryer gets too hot. If it has blown, it means the dryer reached a dangerous temperature. Do not ignore this error — find and fix the root cause before using the dryer again.
Why did my thermal cutout blow in the first place?
Almost always because of restricted airflow. A clogged lint filter, blocked vent duct, or crushed exhaust hose makes the dryer overheat. Fix the airflow problem first, or the new thermal cutout will blow again.
My dryer runs but produces no heat after E05 — what does that mean?
This usually means the thermal cutout has blown and is not resetting. A blown cutout breaks the circuit to the heating element permanently until replaced. The heating element itself may also be damaged and need replacement.
