Possible Causes
Failed piezo buzzer on PCB, Volume setting too low, Faulty timer output, Damaged speaker wiring (if separate)
How to Fix / Troubleshooting
Safety first: Disconnect power before accessing the control board.
Step-by-step checks:
- 1. Check volume settings: Some Zanussi models allow adjustment of buzzer volume via the settings menu. Increase volume if possible.
- 2. Test alarm: Set a short timer and listen closely. If no sound, proceed to hardware checks.
- 3. Inspect buzzer: Locate the buzzer on the PCB (small round component). Check for physical damage.
- 4. Replace PCB or buzzer: On most models the buzzer is integral to the PCB; replace the control board if the buzzer has failed.
Warning: Do not modify the buzzer circuit; this can affect safety alarms.
