Bosch Dryer E01 / E02 Error Code

Bosch groups E01 and E02 as a blocked lint-filter condition. Bosch directs owners to clean the lint filter after each drying cycle and occasionally rinse the lint and fluff filter with warm water.

Applies to Bosch dryer whose exact model documentation uses the listed display

What the appliance detected

Detected condition

The dryer reports that the lint filter is blocked and needs to be cleaned.

What may contribute

Possible causes

  • Lint or fluff may be restricting the filter.
  • The filter may need the model-documented cleaning or rinsing procedure.
  • A code that remains after proper filter care may require model-specific diagnosis.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the display and Bosch model

    • Photograph or write down E01 or E02 before clearing it.
    • Confirm the complete model number and owner manual because Bosch dryer displays and owner procedures vary by model and family.

  2. Use only Bosch-supported owner checks

    • Allow the dryer to stop and cool before handling the filter.
    • Clean the lint filter using the procedure in the exact model manual.
    • Bosch says the lint and fluff filter may occasionally be rinsed with warm water; let it dry and reinstall it exactly as the manual directs before running the dryer.

  3. Respect the dryer service boundary

    • Stop if a check would require removing a panel, reaching internal wiring, testing live voltage, or accessing a heating or gas system.
    • If the display remains or returns after the documented owner check, contact Bosch support or qualified dryer service.

Actions not recommended

  • Do not assume the display applies to another Bosch dryer without checking its exact manual.
  • Do not remove rear or service panels, press an internal reset, or bypass a control or safety device.
  • Do not test mains voltage, capacitors, controls, heating circuits, gas components, or internal wiring.

When to stop and request service

  • E01 or E02 remains or returns after correct filter care.
  • The filter is damaged, will not seat correctly, or the dryer still has poor airflow.
  • There is overheating, a burning smell, smoke, repeated shutdown, or any need for internal vent, sensor, wiring, or heating-system diagnosis.
