What Causes Error SE

high likelihood #1

Stuck or shorted key on the control panel

A button is physically stuck, or moisture has caused a short across the membrane switch.

high likelihood #2

Control panel membrane failure

The flexible membrane layer with the touch-sensitive buttons has worn through or cracked.

medium likelihood #3

Display board failure

The UI/display board that reads button presses has failed.

low likelihood #4

Ribbon cable issue

The flat cable connecting the panel to the control board is damaged or loose.

How to Fix Error SE

  1. Step 1: Power cycle the appliance

    Unplug for 5 minutes. Button errors often clear when the capacitive touch system resets.

  2. Step 2: Clean the control panel

    Wipe the entire panel with a soft damp cloth. Dried spills, grease, or food residue can trigger false button presses. Do not spray cleaner directly on the panel — spray the cloth.

  3. Step 3: Check for stuck buttons

    Press every button on the panel one by one. Feel for any that don't spring back or feel different from the others. A stuck button will continuously trigger the error.

  4. Step 4: Disconnect and reseat the ribbon cable

    Unplug the appliance. Remove the panel cover/screws and carefully reseat the ribbon cable connecting the control panel to the board.

    ⚠️ Ribbon cables are delicate — don't force them.

  5. Step 5: Replace the control panel overlay

    If the membrane touchpad is worn, blistered, or cracked, order a replacement overlay. It typically peels off and the new one sticks on.
