Dishwasher shows iA0 and may not start or may stop shortly after starting.

Safety first: Switch off the dishwasher before adjusting racks or spray arms.

• Check loading: Open the door and ensure large dishes, trays, or utensils are not obstructing the rotation of the upper or lower spray arms. Spin each arm by hand; they should move freely.
• Clean spray arms: Remove the spray arms (usually by unscrewing or unclipping). Rinse under running water and use a toothpick to clear blocked jets.
• Reinstall correctly: Make sure each arm is firmly clipped back into place and can rotate without hitting racks.
• Run a test cycle: Start a short program and listen for normal spray sounds. If the error persists, there may be a circulation pump or water pressure issue requiring professional diagnosis.
