Dryer shows E17; may be related to communication between modules (e.g., main PCB and inverter).

Safety first: Disconnect power before accessing internal electronics.

• Reset appliance: Unplug for 10 minutes, then reconnect and test. Some communication errors clear after a reset.
• Check harnesses: Locate the communication cables between the main PCB and any secondary boards (e.g., inverter, display). Reseat all connectors.
• Inspect for damage: Look for pinched or chafed cables, especially where they pass through metal openings.
• Reduce interference: Ensure the dryer is not sharing a circuit with heavy industrial equipment that could cause electrical noise.
• Board replacement: If E17 persists, one of the boards may be defective. Diagnosis and replacement should be done by an authorized Gorenje technician.
