What Does Error 3 Mean?

The Ariston washing machine error 3 indicates a fault with the temperature sensor (thermistor) or the heating circuit. This often results in the washing cycle stopping unexpectedly or failing to heat water properly. If the error appears during the wash cycle, it may be linked to issues with the inlet valve, preventing the machine from filling with water correctly. Addressing this error typically requires inspecting the temperature sensor and related components.

Common Symptoms:

  • Washing cycle stops or doesn’t progress normally
  • Machine may fail during wash stage or show heating‑related issues
  • Error displayed early in cycle or when warm water is expected

Possible Causes

  • Faulty temperature sensor / thermistor (medium)
  • Heating circuit relay or related component malfunction (low)

How to Fix Error 3

DIY Fix Basic checks before service

  1. Turn off and unplug the washing machine.
  2. Wait a few minutes and power it on again to see if the error persists.
  3. Ensure that inlet hoses are properly connected and that there’s adequate water supply.
  4. Try running a short cycle with a smaller load.

Technician Only Inspect and test temperature sensor and heating circuit

  1. Access the internal temperature sensor (thermistor) and measure its resistance with a multimeter (compare to expected values for the model).
  2. Check continuity and proper connection of the thermistor wiring.
  3. Test the heater relay and associated components if sensor values are normal.
  4. Replace the faulty thermistor or heating circuit parts as needed.

Parts needed: temperature sensor (thermistor), heater relay, associated wiring/connectors

🛑 When to Call a Pro:
  • If the error persists after basic user checks
  • If you are not confident or experienced with internal diagnostics
  • If the machine exhibits additional symptoms such as overheating, no water heating, or repeated interruptions
