Dryer shows E19; may be associated with internal software or configuration error

Safety first: Unplug the dryer before accessing electronics.

• Power cycle: Disconnect power for at least 10 minutes, then reconnect and test. This can clear transient software errors.
• Check for recent repairs: If a control board was recently replaced, ensure it is correctly coded or configured for your Siemens dryer model according to service documentation.
• Factory reset (if available): Some models allow a service reset via a button combination. Refer to the service manual; only perform if documented for your model.
• Replace control module: Persistent E19 usually indicates a defective control board. Replace with a genuine Siemens module pre-programmed for your model.
