The F10 error on your Indesit Washing means the machine has detected a problem with the water heating circuit or the NTC temperature sensor. Checking the wiring and testing the heating element with a multimeter usually confirms the fault.

Error code F10
Meaning Heating element or NTC temperature sensor circuit fault
Severity Medium — the wash cycle will pause or run with cold water only until fixed
Time to fix 20–45 minutes
Tools needed Multimeter, screwdriver set

What the F10 error means

Indesit washing machines use an NTC (Negative Temperature Coefficient) sensor to monitor water temperature during heating. The F10 code appears when the control board doesn’t receive a valid signal from this sensor, or when the heating element itself fails to reach or maintain the expected temperature. This is different from drainage or motor faults such as those covered in the Indesit Washing F02 Error Code guide — F10 is specifically about heating, not water flow.

Common causes

  • Faulty NTC temperature sensor (open or short circuit)
  • Burnt-out or failed heating element
  • Loose or corroded wiring connections to the heater or sensor
  • Limescale buildup insulating the heating element
  • Damaged wiring harness caused by heat or vibration
  • Faulty main control board (less common)

How to fix the F10 error

  1. Power down and unplug the machine — Always disconnect from the mains before opening any panels to avoid electric shock.
  2. Locate the heating element and NTC sensor — These are usually found at the back or underneath the drum, accessed by removing the rear or bottom panel.
  3. Test the NTC sensor with a multimeter — A healthy sensor typically reads around 10k–15k ohms at room temperature. No reading or an infinite reading means it needs replacing.
  4. Test the heating element for continuity — Set the multimeter to continuity mode; no reading indicates the element has burnt out and must be replaced.
  5. Inspect wiring and connectors — Look for corrosion, loose spade connectors, or scorch marks and reseat or replace as needed.
  6. Descale the machine — Run a hot maintenance wash with descaler if limescale is visible, then reset the machine and run a test cycle.

FAQ

Can I still use my machine with an F10 error showing?
You can usually run a cold wash, but hot washes won’t heat properly until the fault is fixed, so it’s best to address it soon.

Is the NTC sensor expensive to replace?
No, NTC sensors are inexpensive parts, typically costing a fraction of what a full heating element replacement costs.

How is F10 different from other heating-related codes?
F10 points to the heating circuit specifically, whereas codes like those in the Indesit Washing F04 Error Code or Indesit Washing F05 Error Code guides relate to drainage and drum sensors.
