Display shows “ERR3” and the coffee maker beeps and stops.

Safety first: Do not bypass safety switches with tape or tools; hot water can cause severe burns.

Check closures:

• Open and firmly close the top lid until you hear or feel a click.
• Ensure the brew basket is fully inserted and level.
• Place the carafe squarely on the warming plate; some models have a carafe presence switch.

Inspect the lid switch:

• Look under the lid for a small plastic tab that presses a hidden switch when closed.
• If the tab is broken or bent, the switch may not engage.

If careful closing does not clear ERR3, the lid or basket switch may be faulty and require replacement. This typically involves opening the housing and should be done by a technician.
