What to Check Next on This Bosch Dryer Use these checks before ordering parts for Bosch dryer F57. 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. Recommended Parts to CheckBosch dryer part numbers vary by model.
