How to Fix Error 4

DIY Fix Check for simple issues and code interpretation

  1. Turn the machine off and unplug it for at least 5 minutes, then plug back in and restart (simple reset attempt).
  2. Check the user manual specific to your exact Ariston model for an error code list (some models list error codes as F01, F02, etc.).
  3. Verify that the displayed code isn’t actually F04 (which some Ariston error lists show) rather than just "4".
  4. Check common issues that can show generic errors such as door not fully closed, supply water valve closed, kinked hoses, or heavy load imbalance.

Technician Only Model‑specific diagnostics

  1. Obtain the exact model number of the Ariston washing machine.
  2. Consult official service manual for that specific model to interpret the code correctly.
  3. Use diagnostic tools to read any internal fault logs.
  4. Verify sensors (door lock, pressure switch, etc.) and controller communications.
🛑 When to Call a Pro:
  • If the machine continues to display an undefined code after basic checks and cannot start any cycle.
  • If any obvious fault (water leak, burning smell, loud noise) accompanies the error.
