E9 error on display; unit may not respond to button presses or may behave erratically.

Safety: Unplug the ice maker before removing the control panel or top cover.

Steps:

• 1. Power cycle: Disconnect power for 10 minutes, then reconnect. If E9 persists, continue.
• 2. Access control panel: Remove the screws securing the top/front panel to expose the control PCB and keypad ribbon cable.
• 3. Inspect for moisture: Look for condensation or water droplets on the control board. If present, dry gently with a soft cloth and allow the unit to air dry for several hours.
• 4. Reseat ribbon cable: Carefully unplug and reinsert the keypad ribbon cable into the main board connector, ensuring it is fully seated and straight.
• 5. Check for corrosion: Examine the connector pins and PCB for corrosion or burn marks. Light corrosion can sometimes be cleaned with isopropyl alcohol and a soft brush.
• 6. Replace faulty parts: If buttons still do not respond or E9 remains, replace the Vremi control panel keypad assembly. If that does not help, the main control board likely needs replacement.

Warning: Avoid spraying cleaners directly onto the control panel; apply to a cloth first to prevent future moisture damage.
