Problem: Door is not locked properly.
How to Fix E34 / F34 Error (Step-by-Step)

What to Check Next on This Bosch Dryer
Bosch Dryer Error E34 / F34: Use the code, light, or symbol as the starting clue, then confirm what the dryer actually does before ordering parts.
- 1. Unplug the dryer before removing panels, checking the heater, thermal fuse, moisture sensor, door switch, motor, fan, harness, or control board.
- 2. Clean the lint screen and verify the full vent path has strong airflow before replacing heat or control parts.
- 3. Keep E34 and F34 together on this grouped Bosch dryer page: both should be checked against airflow, heat demand, sensor feedback, harness connections, and the control response before parts are ordered.
- 4. Check the door latch, drum movement, lint buildup, vent restriction, moisture sensor bars, loose connectors, and signs of overheating before ordering parts.
- 5. Run a timed dry test after airflow corrections and note whether the failure is no start, no heat, weak airflow, long dry time, or display/control behavior.
- 6. Replace a part only after the same symptom repeats and model-specific checks point to that part category. Match any replacement to the complete Bosch dryer model number on the appliance tag.
If the issue returns after these checks, match replacement parts to the complete Bosch dryer model number from the appliance tag. The same display clue can point to different components depending on the exact model and when the failure appears.
