Dishwasher will not start a cycle, all LEDs may flash or start/pause light blinks repeatedly shortly after pressing start.

Safety first: Disconnect the dishwasher from the mains supply (unplug or switch off at the fused spur) before removing any panels.

Step-by-step checks:

• Confirm power supply: Verify the wall socket or fused spur is live using another appliance. Check the dishwasher plug and cable for damage.
• Inspect the mains filter and wiring: Remove the lower front kick panel. Locate the mains interference filter (usually where the power cord enters). Check for burnt smell, discoloration, or loose spade connectors. Reseat any loose connectors.
• Check door harness: Open the outer door panel (screws around the inner door). Inspect the wiring loom where it bends at the door hinge. Look for broken or chafed wires and repair with heat‑shrink and proper crimp connectors.
• Control board inspection: Access the control module in the door. Look for burnt tracks, swollen capacitors, or a charred relay. If any damage is visible, the PCB should be replaced rather than repaired in‑home.
• Test after reassembly: Reassemble panels, restore power, and attempt a short cycle. If F01 persists and supply/wiring are sound, the control board is likely defective.

When to stop: If you smell burning, see heavy charring on the PCB, or the breaker trips repeatedly, discontinue use and contact a qualified Indesit technician.
