Dishwasher powers on but will not start a cycle; Start button unresponsive or program will not begin.

Safety first: Disconnect power before removing the control panel.

• Step 1 – Check display messages:
  • Look for a key symbol or child lock indicator; if present, disable child lock per user manual (often by holding a specific button combination).
• Step 2 – Door closure:
  • Ensure the door is fully closed and latches with a firm click.
  • Check for obstructions around the door seal or racks preventing closure.
• Step 3 – Control panel:
  • If some buttons work but Start does not, the keypad or touch sensor may be faulty.
  • Remove the inner door panel and inspect the user interface board and ribbon cable for damage or corrosion.
• Step 4 – Reset:
  • Turn off power for 5 minutes, then restore and attempt to start a basic program.
• Step 5 – Replacement:
  • If the Start button or UI board is defective, replace the user interface module.

Do not force the door closed; fix alignment issues if the latch does not engage smoothly.
