Neff oven displays E024 and the steam-assisted or added-steam function does not work (on steam models)

Safety first: Allow the oven to cool and disconnect power before accessing internal steam components.

• Check water tank: Ensure the water tank is filled to the correct level and properly seated in its compartment.
• Clean tank contacts: Wipe the electrical contacts on the tank and in the oven with a dry cloth to ensure good connection.
• Descale system: If the oven indicates descaling is needed, run the descaling program using the recommended descaler for Neff steam ovens.
• Inspect steam inlet: Check the steam outlet/inlet inside the cavity for blockages and clean gently.

If E024 persists, the steam generator heater or level sensor may be faulty and typically requires professional service.
