The F05 error on your Indesit Dryer means the machine has detected a fault with the moisture sensor circuit that measures how dry your laundry is. This usually stops the drying cycle partway through or prevents it from starting at all. In most cases this is a sensor or wiring issue rather than a major mechanical fault, and it can often be fixed at home.

Error code F05
Meaning Moisture/humidity sensor fault or wiring problem
Severity Medium — dryer may still run but drying performance is affected
Time to fix 15–40 minutes
Tools needed Screwdriver, soft cloth, multimeter (optional)

What the F05 error means

Indesit dryers use a moisture sensor, usually two metal strips inside the drum, to detect when clothes are dry enough to end the cycle. The F05 code appears when the control board can’t get a reliable reading from this sensor, either because it’s dirty, damaged, or disconnected. This is similar in nature to sensor-related faults seen on Indesit washing machines, such as the Indesit Washing F02 Error Code or the Indesit Washing F05 Error Code, where a sensor reading falls outside expected limits.

Because the moisture sensor is a small, exposed part inside the drum, it’s one of the more common points of failure over time, especially with heavy use or lint buildup.

Common causes

  • Dirty or lint-covered moisture sensor strips inside the drum
  • Limescale or fabric softener residue coating the sensor contacts
  • Loose or damaged wiring connector behind the drum
  • Faulty moisture sensor that needs replacing
  • Control board fault misreading sensor signals
  • Water or condensation affecting internal wiring

How to fix the F05 error

  1. Unplug the dryer — Always disconnect power before inspecting or cleaning any internal parts for safety.
  2. Clean the moisture sensor strips — Open the door and locate the two metal strips inside the drum, usually near the front. Wipe them gently with a soft cloth dampened with water or vinegar to remove residue.
  3. Check the wiring connections — Remove the top or front panel to access the sensor wiring and confirm the connector is firmly plugged in and undamaged.
  4. Test with a multimeter — If comfortable doing so, check the sensor for continuity to confirm it’s still functioning correctly.
  5. Restart the dryer — Plug it back in and run a short cycle to see if the F05 code clears after cleaning.
  6. Replace the sensor or board if needed — If the fault persists, the moisture sensor or control board may need replacing by a qualified technician.

FAQ

Can I keep using the dryer with an F05 error?
You can try running cycles, but the dryer may stop early or not dry clothes properly until the fault is resolved.

Is cleaning the sensor strips safe to do myself?
Yes, this is a simple, low-risk task as long as the dryer is unplugged first.

Does F05 mean the dryer is broken permanently?
No, it’s often caused by residue buildup or a loose connection, both of which are usually repairable without replacing major parts.
