How to Fix / Troubleshooting
Safety first: Disconnect power before removing the control panel.
- Attempt reset: Turn off power for several minutes, then restore and attempt to set the clock according to the user manual.
- Inspect timer module: Remove the control panel fascia and locate the clock/timer module. Check for burnt components or bulging capacitors.
- Check connectors: Ensure all plugs to the timer are firmly seated and free of corrosion.
- Replace timer module: If the clock still cannot be set or keeps losing time, replace the timer/clock module with a genuine Ariston part. Transfer wiring one connector at a time.
- Re-test: Set the time and verify that the oven can now start and run cooking programs.
