Wine cooler displays E6 and the display may be blank, flickering, or unresponsive.

Safety: Disconnect power before removing the control panel. Handle display boards carefully to avoid cracking or static damage.

Steps:

• Remove control panel: Take out screws securing the top/front panel and gently pull it forward.
• Inspect ribbon cable: Check the flat cable or harness connecting the display to the main control. Look for kinks, cuts, or burn marks.
• Reseat connectors: Unplug the ribbon cable from both ends and reconnect firmly. Ensure it is fully inserted and locked.
• Check for moisture: Look for signs of condensation or liquid intrusion around the display. Dry the area thoroughly if needed.
• Test operation: Reassemble enough to safely power the unit and see if E6 clears. If the error persists, proceed.
• Replace UI board: If wiring is intact, the user interface board is often the failed component. Install a Whirlpool-compatible replacement, transferring any overlay or trim as required.
• Consider main board: If a new UI does not resolve the issue, the main control board may have a communication fault and should be replaced.

Note: Do not pinch the ribbon cable when reinstalling the panel; this can cause intermittent errors.
