How to Fix / Troubleshooting

Check power source:

  • Ensure the coffee maker is plugged directly into a stable outlet, not a switched power strip.
  • Avoid outlets that are frequently turned off.

Observe behavior:

  • Note whether the clock resets only after power outages or randomly.

Internal inspection (advanced):

  • Inspect the control board for bulging capacitors or signs of damage.

If the clock resets randomly despite stable power, the control board likely needs replacement.
