Safety: Unplug the microwave before removing the control panel or touching internal wiring.

User-level steps:

1. Power cycle: Unplug for 5–10 minutes, then plug back in and test the keypad. Sometimes static or minor glitches can trigger E6.
2. Dry out moisture: If steam has been venting directly toward the control panel, leave the door open and allow the unit to dry for several hours. Avoid boiling large pots directly under built-in units.
3. Test all keys: Try pressing each button. If some keys work and others do not, the membrane keypad is likely failing.

Advanced checks:

Remove the control panel assembly (usually by removing screws around the trim and lifting the panel).
Gently disconnect and reseat the keypad ribbon cable on the control PCB.
If E6 persists and keys remain unresponsive, replace the membrane keypad or the entire control panel assembly, depending on Tower model design.

Note: Avoid using harsh cleaners or excessive water on the keypad surface, as this can cause future failures.

Microwave displays E6 and will not start; keypad may seem unresponsive or partially responsive.
