E11 is displayed and the machine indicates a door or service panel open, even when it appears closed.

Safety first: Unplug the machine before manipulating the door or switch area.

• Open and close door: Open the service door fully and then close it firmly until you hear a click. Do not slam, as this can break the latch.
• Inspect latch tab: Look for a small plastic tab on the door that presses the internal switch. If it is cracked or missing, the switch will not engage.
• Check for obstructions: Ensure no coffee grounds or foreign objects are preventing the door from closing completely.
• Test with gentle pressure: With the machine plugged in, gently press on the door while trying to start a cycle. If E11 disappears only when pressing, the latch or switch is misaligned and needs adjustment or replacement.
• If E11 persists: The door microswitch or wiring harness likely needs replacement by a technician.
