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.

- 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)
