Oven display works but heating only occurs when the clock is set, or oven will not start until time is set

Safety first: No internal work is required for this issue; no need to disconnect power.

Step-by-step checks:

• 1. Set the clock: Press the clock or timer button and use +/- or rotary controls to set the correct time. Confirm with the OK or clock button.
• 2. Exit automatic mode: If an AUTO symbol is lit, cancel any programmed start/stop times by pressing the timer button repeatedly and setting all times to zero or manual mode (see Zanussi user manual).
• 3. Test heating: Once the clock shows a steady time and manual symbol, select a cooking function and temperature. The oven should now heat.

Warning: If the timer cannot be set or remains in AUTO, the timer module may be faulty and require replacement.
