Common problems
Condensing dryer taking longer than expected
What you notice: Condensing dryer taking longer than expected.
What to check: This 300 Series dryer has a user-cleanable condenser. Follow Bosch's exact manual for the lint filter and condenser; allow the appliance to cool before maintenance.
When to stop: The dryer overheats, trips a breaker, leaks, or airflow remains poor.
Cycle ends with damp clothes
What you notice: Cycle ends with damp clothes.
What to check: Check that the load and chosen programme match the care labels. Review the model's sensor and dryness guidance rather than assuming an internal heater failure.
When to stop: The same programme repeatedly fails after routine documented checks.
Container or lint warning
What you notice: Container or lint warning.
What to check: Read the exact icon or text in the manual; empty the condensation container or clean the lint filter only as directed for this model.
