Dishwasher fills but circulation does not start, or cycle stops early with F02 indicated by flashing LEDs or on the display.

Safety: Isolate the appliance from mains power before working underneath or inside the base.

Access and inspection:

• Pull the dishwasher out from under the counter enough to access the left or bottom service panel (varies by Indesit model).
• Remove the lower panel to expose the circulation pump assembly attached to the sump.
• Disconnect the pump electrical connector and check for signs of overheating or corrosion.
• Remove the pump (usually a twist‑lock or a few Torx screws). Inspect the impeller area for glass, bone fragments, or food debris. Clear any obstruction.

Functional checks:

• Spin the impeller by hand; it should turn smoothly without grinding.
• Use a multimeter to measure resistance across the motor terminals. An open circuit (infinite resistance) indicates a failed motor.
• Inspect the wiring harness from the pump back to the PCB for cuts or burn marks.

Reassembly:

• Refit or replace the circulation pump, ensuring the seal is correctly seated to avoid leaks.
• Reconnect wiring, refit the base panel, push the machine back, restore power, and run a test cycle.

If the error returns after clearing obstructions, the circulation pump assembly will typically need replacement.
