Neff oven will not start heating unless the time is set, user unsure why

Safety first: No internal work required.

• Set the time: After any power interruption, set the clock to the correct time. Many Neff ovens will not heat until this is done.
• Cancel automatic programs: Ensure the timer is not set to 'auto' or delayed start. Press the manual or hand symbol to return to manual mode.
• Consult manual: Refer to the user manual for the specific sequence to exit timer modes.
