What Does Error F05 Mean?

The Ariston washing machine error F05 indicates a malfunction in the drain system, often caused by a clogged drain filter, hose, or a faulty pressure switch. This error prevents the machine from draining water effectively, leading to issues such as water remaining in the drum, unusual buzzing noises from the pump, and interruptions during the rinse and spin cycles. To resolve this issue, it is essential to check for blockages and ensure the pressure switch is functioning correctly.

Common Symptoms:

  • Water remains in drum after program
  • Machine stops mid‑cycle during switch to rinse/spin
  • Possible buzzing from pump without effective drain
  • Error appears after some time, not immediately

Possible Causes

  • Clogged drain system (filter/hose/trap) (medium)
  • Pressure switch not detecting correct water level (jammed/blocked tube) (medium)
