Dryer shows E16; may not respond to button presses or may behave erratically.

Safety first: Disconnect power before removing the control panel. Avoid using excessive force on buttons.

• Check for stuck buttons: Press each button individually and ensure it returns freely. If a button feels stuck, gently work it free or remove debris around it.
• Dry moisture: If the panel has been exposed to steam or liquid, remove the control panel and allow it to dry completely in a warm, dry place for 24 hours.
• Inspect keypad membrane: Look for cracks, warping, or signs of delamination. Replace the membrane or entire UI panel if damaged.
• Clean contacts: For mechanical switches, use contact cleaner on the switch terminals (with power disconnected).
• Reassemble and test: After cleaning and drying, reconnect and test. Persistent E16 usually indicates the need for a new UI board.
