Dishwasher displays E17; the unit may not recognize the door status correctly, starting and stopping unexpectedly.

Safety first: Disconnect the power before working on the door.

• Check door alignment: Ensure the dishwasher is level and not twisted within the cabinet, which can misalign the latch.
• Inspect latch mechanism: Remove the inner door panel and examine the latch and switch. Look for wear, cracks, or loose screws.
• Test switch: Use a multimeter to verify that the door switch changes state when the latch is engaged.
• Replace latch/switch: If worn or faulty, install a new door latch / door switch assembly.
