What should I do if an error F03 appears on the display of your car? This means a malfunction of the temperature sensor in SM Ariston or Hotpoint Ariston models.
You may have noticed that when choosing any mode, the system heats the water to boiling, and hot steam comes out of the door.
What the error means: causes and signs of failure
Hotpoint Ariston washing machine (Ariston) shows error code F03 on the display. So, her work failed - when choosing the minimum heating program (30 degrees), the washer heats the water to boiling.
Do you notice that the body of the SMA is very hot? A faulty temperature sensor sends incorrect data to the control board, as a result of which the heater burns out.
In rare cases, the TEN relay “sticks”, or there are malfunctions in the control module, so the machine gives an error. How to fix the breakdown, what to do to solve the problem, read below.
Troubleshooting
Start with simple steps that will help remove the error F 03. Restart the Ariston washing machine, turn it off for 15-20 minutes. If the error did not reset, and the code is still displayed, try the following:
- Check the reliability of the wires between the temperature sensor and the control unit. Damage may have occurred. Then replace the defective area or wiring completely.
- Use a multimeter to check the temperature sensor.
Most often, temperature sensors fail due to mechanical damage or long operation.
If the contact group burns during a breakdown, then the circuit closes. As a result, the system issues DTC F03. To figure out how to fix the problem, you need to check the temperature sensor.
Thermostat check
Depending on the Ariston range, there are three types of thermostats:
- Gas-filled and bimetallic belong to the electromechanical group.
- Thermistor - to the electronic group.
To check bimetallic and gas-filled sensors, do this:
- Remove the back cover of the Ariston washer.
- To remove the gas-filled sensor, you will need to remove the front panel of the machine.
- Disconnect the contacts, wires from the thermostat.
- Loosen the bolt securing the electric heater.
- Connect the multimeter to the thermostat contacts and measure the resistance (6000 Ohm at 20 degrees).
- Dip the appliance in hot water. The health indicator should be 1350 ohms at 50 degrees.
In the event of a malfunction, the thermostat cannot be repaired. To replace, remove the sealing rubber and remove the sensor. Install the new device in the reverse order.
Replacing a thermistor is similar.
If everything is done correctly, error F 03 will cease to burn on the display, and the machine will work in normal mode.
