What to Check Next on This Bosch Dryer Use these checks before ordering parts for Bosch dryer E20. 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.

If the code comes back

Do not keep replacing parts based only on the code. Repeat the safe checks above. If the fault remains, stop and arrange qualified service rather than ordering from the code alone.

What may be causing it?

  • Fault with the electronic control module
  • Control board failure

These are possibilities to investigate, not proof that one part has failed.
