Bodum coffee maker with clock/timer shows E6 and none of the buttons respond, or the display is frozen.

Safety first: Unplug the coffee maker before touching the control panel internals.

Steps to try:

• Power cycle reset: Unplug the unit for at least 15 minutes to fully discharge internal capacitors. Plug back in and check if the display and buttons respond normally.
• Dry out moisture: If the machine was recently cleaned with excessive water or steam, leave it unplugged in a dry, warm room for 24 hours. Do not use hair dryers or heat guns directly on the panel.
• Inspect keypad connection (advanced): With the unit unplugged, remove the top or front cover to access the control board. Locate the flat ribbon cable from the keypad. Gently disconnect and reconnect it to clean the contacts. Ensure it is fully seated and not pinched.
• Check for corrosion: Look for green/white corrosion on the PCB or keypad contacts. Light corrosion can sometimes be cleaned with isopropyl alcohol and a soft brush, but heavy damage usually requires board replacement.

If E6 persists: The control board or keypad membrane is likely defective. Replacement is typically a level-4 repair and may not be economical on low-cost models.
