What Does Error F03 Mean?

The Ariston dryer F03 error code indicates a malfunction in the thermistor or temperature sensor circuit, which can be open or short-circuited. This fault results in the dryer failing to generate heat, leading to symptoms such as the dryer stopping shortly after starting, incorrect heating, and drying cycles that do not complete. Addressing this issue involves checking the heating element and thermistor for faults.

Common Symptoms:

  • Dryer stops shortly after starting
  • No or incorrect heating
  • Drying cycle fails to complete

Possible Causes

  • Thermistor (temperature sensor) circuit open or short (medium)

How to Fix Error F03

DIY Fix Basic visual checks and restart

  1. Turn off the dryer and disconnect from power.
  2. Check for obvious signs of damage to wiring around the door and accessible panels.
  3. Reconnect power and try running a short cycle to see if the error reoccurs.

Technician Only Diagnose and replace faulty thermistor or repair wiring

  1. Disconnect the dryer from power and remove access panels to reach the thermistor and its harness.
  2. Use a multimeter to test continuity and resistance of the temperature sensor (thermistor) against manufacturer specifications.
  3. Inspect associated wiring and connector for damage, corrosion, or shorts.
  4. Replace the thermistor if it is open/short or out of spec; repair wiring as needed.

Parts needed: NTC temperature sensor (thermistor), Wiring harness/connectors
