Display shows E5 and the Swan coffee maker stops mid-cycle or will not start; often associated with lid or carafe not detected.

Safety first: Unplug the coffee maker before manipulating switches or covers.

Simple checks:

• Close all lids firmly: Open and close the brew basket lid and any top cover several times, pressing down until you feel a positive click.
• Seat the carafe: Ensure the Swan glass carafe is fully pushed back on the warming plate so that the spout actuator properly engages the drip-stop mechanism.
• Clean the drip-stop: Remove the filter basket and clean the spring-loaded drip-stop valve. Coffee residue can prevent the switch from recognizing the carafe.

Switch inspection:

• With the unit unplugged, locate the lid micro-switch (usually under the top cover) and the carafe presence switch (under the warming plate or near the drip-stop).
• Press each switch manually and listen for a distinct click. A mushy or silent switch may be faulty.
• If you have a multimeter, test continuity across the switch terminals when pressed. Replace any switch that does not change state.

Reassembly: After replacing a switch, ensure all covers and screws are reinstalled correctly so that the actuators align with the new components.
