Washer-dryer combo shows E14 and may not respond correctly to button presses; display or controls behave erratically.

Safety first: Unplug the unit before removing the control console. Avoid using excessive liquid cleaners on the panel.

Step-by-step checks:

• 1. Power cycle: Disconnect power for several minutes, then restore. Sometimes transient keypad errors clear after a reset.
• 2. Inspect the control panel: Check for signs of liquid spills, cracks, or physical damage to the buttons. Dry any moisture with a soft cloth.
• 3. Remove and inspect the console: Take off the control console to access the user interface board. Reseat the ribbon cable or harness connecting it to the main control board.
• 4. Check for corrosion or damage: Examine the user interface board for corrosion, burned components, or damaged traces. Replace the OEM Monogram user interface board if defects are found.
• 5. Test button function: After reassembly, enter diagnostic mode (per service manual) to test each button input. Replace the panel if certain keys do not register.

When to call a technician: If E14 persists after panel and cable checks, further electronic diagnosis is needed and is best handled by a Monogram service technician.
