Oven clock and settings reset every time power is switched off, or time cannot be set correctly.

Safety first: Disconnect power before accessing wiring.

• Check wiring: Verify that the permanent live and neutral are correctly connected to the clock module as per wiring diagram. Incorrect wiring can cause loss of settings.
• Measure supply: Ensure stable voltage is present at the clock module terminals.
• Replace clock: If wiring and supply are correct but settings are lost, replace the clock/timer module.
