E17 error; ice maker disabled due to detected door switch fault.

Safety: Disconnect power before testing switches.

• Check interior light: If the freezer light stays on when the door is closed, the door switch is likely faulty or misaligned.
• Inspect switch: Locate the Bosch door switch near the door frame. Press it manually and listen for a click. If it feels loose or does not click, it may be defective.
• Test continuity: Remove the switch from the liner, disconnect wires, and test with a multimeter. It should open and close circuit when pressed and released.
• Replace switch: Install a new Bosch door switch, reconnect wires, and snap it back into place. Ensure the door fully depresses the switch when closed.
• Check hinge wiring: On some models, door switch wiring runs through the hinge. Inspect for broken wires and repair as needed.
