Why Understanding Ariston Error Codes Matters

Every Ariston washer continuously monitors components such as:

  • Water inlet valves
  • Drain pump
  • Door lock
  • Heating element
  • Temperature sensor
  • Pressure switch
  • Motor
  • Electronic control board

Whenever one of these components develops a fault, the machine displays an error code beginning with the letter F.

Correct diagnosis prevents replacing unnecessary parts and saves both time and money.

F01 – Motor Triac Short Circuit

Meaning

The electronic control board has detected a short circuit in the motor control triac. This prevents the motor from operating safely.

Possible Causes

  • Shorted motor
  • Damaged wiring
  • Burnt control board
  • Moisture damage
  • Failed triac

How GossTech Diagnoses F01

Step 1: Disconnect electrical power.

Step 2: Remove the rear panel.

Step 3: Inspect the motor wiring.

Step 4: Measure motor winding resistance.

Step 5: Test for short circuits.

Step 6: Inspect the control PCB for burnt components.

Repair Procedure

  • Replace damaged wiring.
  • Replace faulty motor if windings are shorted.
  • Repair or replace the PCB if the triac has failed.
  • Test the machine through a complete wash cycle.

F02 – Motor Rotation Fault

Meaning

The control board cannot detect motor movement even though power is being supplied.

Possible Causes

  • Worn carbon brushes
  • Faulty tachometer
  • Broken drive belt
  • Motor failure
  • Loose wiring

Diagnosis

  1. Inspect the drive belt.
  2. Check motor brushes.
  3. Measure tachometer resistance.
  4. Rotate drum manually.
  5. Test motor operation.

Repair

  • Replace worn brushes.
  • Install a new tachometer if defective.
  • Replace broken drive belt.
  • Repair motor wiring.
  • Replace motor if necessary.

F03 – Temperature Sensor Error

Meaning

The thermistor is sending incorrect temperature readings.

Causes

  • Faulty NTC sensor
  • Loose wiring
  • Water damage
  • PCB malfunction

Diagnosis

  • Disconnect power.
  • Locate the thermistor.
  • Measure resistance.
  • Compare readings with specifications.
  • Inspect connectors.

Repair

  • Replace faulty thermistor.
  • Clean corroded terminals.
  • Secure loose wiring.
  • Test heating cycle.

F04 – Pressure Switch Error

Meaning

The pressure switch cannot accurately detect the water level inside the drum.

Causes

  • Blocked pressure hose
  • Faulty pressure switch
  • Air leak
  • PCB fault

Diagnosis

  1. Remove the top cover.
  2. Inspect the pressure hose.
  3. Blow through the hose.
  4. Test pressure switch continuity.
  5. Run calibration.

Repair

  • Replace damaged hose.
  • Install new pressure switch.
  • Clean air chamber.
  • Verify correct filling.

F05 – Drain System Failure

Meaning

Water is not draining properly.

Common Causes
