The F2 error on your Indesit Dishwasher means the machine has detected a water leak or overflow condition inside the base of the unit. Turn off the dishwasher and check underneath it for standing water before restarting.

Error code F2
Meaning Water leak or overflow detected by the base tray sensor
Severity High — the machine will not run a cycle until the leak is cleared
Time to fix 15–45 minutes
Tools needed Towels, torch, adjustable pliers (for hose clips)

What the F2 error means

Indesit dishwashers have a small float switch or leak sensor sitting in the base tray under the tub. If water collects there — from a leaking hose, a cracked seal, or overfilling — the sensor trips and the control board locks the machine with an F2 code as a safety measure. This stops the dishwasher from running and potentially flooding your kitchen floor.

It’s the dishwasher equivalent of the flood protection seen on washing machines, similar in principle to the Indesit Washing F02 Error Code on washer models.

Common causes

  • A leaking door seal or gasket letting water drip into the base
  • Loose or split water inlet or drain hose connections
  • A cracked or damaged spray arm leaking during the wash cycle
  • Overfilling caused by a faulty water inlet valve
  • A stuck or faulty float switch giving a false reading
  • Detergent overdosing causing excess foam and overflow

How to fix the F2 error

  1. Switch off and unplug the dishwasher. Always disconnect power before checking for water or handling any internal parts.
  2. Check the base tray for standing water. Tilt the dishwasher forward slightly or remove the front kick panel to inspect for pooled water and soak it up with towels.
  3. Inspect the door seal and gasket. Run a finger around the rubber seal to feel for splits, tears, or a stiff, perished section that needs replacing.
  4. Check hose connections at the back. Make sure the inlet and drain hoses are firmly clipped on and not cracked or kinked.
  5. Test the float switch. Locate the small float in the base tray and gently move it up and down to confirm it isn’t stuck in the “high water” position.
  6. Restart the dishwasher. Once the base is dry and all connections are secure, plug it back in and run a short cycle to confirm the F2 code has cleared.

FAQ

Can I keep using the dishwasher after an F2 error?
No. Running it again before finding the leak risks water damage to your kitchen floor and cabinets, so fix the cause first.

Why does F2 keep coming back after I dry the base tray?
This usually means the leak is ongoing rather than a one-off spill — check the door seal, hose clips, and spray arm again more closely as the source is still active.

Is the F2 error the same on all Indesit dishwasher models?
The exact fault code numbering can vary slightly by model year, so check your user manual to confirm F2 refers to a leak or overflow on your specific unit.
