Bosch Dryer Error Codes (What They Mean + Fixes)

by

If your Bosch dryer is showing an error code, this guide explains what the code usually means, the most common causes, and safe checks you can try before calling service.

Note: Error codes can vary by Bosch model (condenser vs heat-pump). The explanations below apply to most modern Bosch dryers.

Common Bosch Dryer Error Codes

E01 — Heating Error

What it usually means

  • The dryer is not heating correctly or temperature rise is insufficient.

Try this

  1. Clean the lint filter thoroughly.
  2. Check airflow paths for lint buildup.
  3. Run a timed dry cycle to test heating.

Call service if

  • The dryer runs but does not heat after airflow checks.

E02 — Temperature Sensor Error

What it usually means

  • A fault with the temperature sensor or wiring.

Try this

  1. Power off at the wall for 5 minutes.
  2. Restart and test a short cycle.

Call service if

  • E02 returns immediately.

E03 — Airflow / Overheating Error

What it usually means

  • Restricted airflow causing excessive temperature.

Try this

  1. Clean lint filter and heat-exchanger (heat-pump models).
  2. Ensure the dryer has adequate ventilation space.
  3. Avoid overloading.

Call service if

  • The dryer shuts down repeatedly with E03.

E04 — Condensation / Drain Error

What it usually means

  • Condensed water is not draining correctly.

Try this

  1. Empty and reseat the water tank (if applicable).
  2. Clean the condenser/heat exchanger.
  3. Check drain hose routing (if plumbed).

Call service if

  • Water does not move despite pump noise.

E05 — Motor Error

What it usually means

  • A problem with the drum motor or motor feedback.

Try this

  1. Reduce load size and redistribute items.
  2. Power off for 10 minutes and retry.
  3. Ensure the drum turns freely by hand (off).

Call service if

  • E05 appears on small loads or immediately on start.

E06 — Door / Lock Error

What it usually means

  • The door is not closing or locking properly.

Try this

  1. Re-close the door firmly.
  2. Remove laundry caught in the seal.
  3. Power cycle and retry.

Call service if

  • The door will not lock or the error persists.

E09 — Heater Circuit Error (Heat-Pump Models)

What it usually means

  • A fault in the heater or heat-pump circuit.

Try this

  1. Power off at the wall for 5 minutes.
  2. Clean filters to improve airflow.

Call service if

  • E09 reappears (professional diagnosis required).

How to Clear a Bosch Dryer Error Code

  1. Turn the dryer off.
  2. Turn off power at the wall for 5 minutes.
  3. Restore power and start a short test cycle.

If the error reappears immediately, it indicates an active fault.

When to Call Service

  • Persistent heating or overheating errors
  • Repeated motor or heater circuit faults
  • Drain errors that continue after cleaning
  • Burning smells, tripped breakers, or visible damage

FAQ

Can blocked filters cause Bosch dryer error codes?

Yes. Lint and heat-exchanger blockage is a very common cause of heating and airflow errors.

Do heat-pump dryers show different codes?

Some do, but airflow, sensors, and drainage issues remain the most common triggers.

Is it safe to keep resetting the dryer?

No. Repeated resets without fixing the cause can damage components.
