Bosch Dryer Error Code E08 — Heating Element Failure
What this means
Error E08 indicates the heating element has failed or its circuit is broken. The dryer will tumble but clothes will not dry. This can be caused by a burned-out element, a blown thermal fuse, or a faulty high-limit thermostat that has cut power to the element.
Step-by-step fix
4 stepsCheck the thermal fuse
Locate the thermal fuse (usually on the blower housing or heating element housing). Test for continuity with a multimeter.
A blown thermal fuse usually indicates a vent blockage that caused overheating.
Test the heating element
Disconnect the element and test for continuity. It should show resistance (typically 10–50 ohms). No continuity means it has burned out.
Check the high-limit thermostat
Test the high-limit thermostat for continuity. If it is open, it has tripped and cut power to the element.
A tripped high-limit thermostat is often a symptom of restricted airflow.
Replace failed components
Replace any components that test faulty. Also clean the vent system to prevent future failures.
Always address the root cause (usually poor airflow) when replacing thermal fuses.
