Display shows E14; unit may not respond to button presses or responds erratically.

Safety first: Disconnect power before removing the front control panel.

• Dry the control area: If condensation or spills have reached the panel, allow the unit to dry completely. Use a dry cloth around the panel edges.
• Inspect ribbon cable: Remove the front panel and check the flat cable for kinks, cracks, or corrosion at the connectors. Reseat both ends firmly.
• Check for stuck buttons: Press each button individually to feel for sticking. Clean the panel surface with a mild detergent and soft cloth.
• Visual inspection of UI board: Look for burnt components or corrosion on the user interface PCB.
• Replace UI module: If E14 persists and buttons remain unresponsive, replace the complete user interface / display board with the correct Gorenje part.
