How to Fix / Troubleshooting
Safety first: Unplug the dryer. This fault involves live‑voltage components; do not attempt board‑level repair without proper training.
- Visual inspection: Remove the top cover and inspect the control board for burnt components near the motor or pump drive area.
- Check motor and pump wiring: Inspect harnesses to the drum motor and condensate pump (if fitted) for pinched or shorted wires touching the cabinet.
- Isolate components: A technician may disconnect the motor or pump to see if F11 changes, helping to identify which load is causing the drive fault.
- Board replacement: If the triac or PCB is damaged, replace the entire control board with the correct Ariston part number.
