How to Fix / Troubleshooting

Safety first: Unplug the ice maker before removing the control panel.

Steps to resolve E11:

  • Dry the panel: If the panel is wet from spills or condensation, unplug the unit and allow it to dry completely for several hours.
  • Inspect the keypad: Remove the front/top bezel to access the keypad or display PCB. Look for corrosion or moisture marks.
  • Check ribbon cable: Reseat the ribbon cable between the keypad and main control board. Ensure it is not kinked or torn.
  • Test buttons: If accessible, use a multimeter to check continuity across button contacts when pressed.
  • Replace if defective: Install a new Tristar user interface / keypad assembly if buttons are unresponsive or the PCB is damaged.
  • Reassemble and test: Refit the panel, restore power, and verify all buttons and indicators work correctly and E11 is cleared.
