Dryer displays E15; may be associated with internal memory or configuration error on some Blomberg controls.

Safety first: Unplug the dryer before accessing the control board.

E15 suggests an internal software or memory problem in the main control.

• Power reset: Disconnect power for at least 10 minutes to allow capacitors to discharge. Reconnect and see if the error clears.
• Check model configuration: If the control board was recently replaced, ensure it is the correct part number for your exact Blomberg dryer model and that any required configuration steps (jumpers or programming) were performed.
• Inspect the board: Look for obvious damage such as burn marks or corrosion. If present, the board must be replaced.
• Firmware update (service-only): Some boards can be reprogrammed with manufacturer tools. This is typically done by an authorized service center.
• Board replacement: If E15 persists and no external cause is found, replace the main control board. Label all connectors before removal to avoid miswiring.
