Steam-assisted or moisture function error on compatible De Dietrich oven models

Safety first: Disconnect power and allow the oven and steam system to cool before servicing. Hot steam can cause severe burns.

• Check water tank: Ensure the water reservoir is filled and correctly inserted. Clean the tank and its contacts if present.
• Descale system: Run a descaling cycle if the model supports it, using the recommended descaling agent. Follow the user manual.
• Inspect hoses and connections: Access the steam generator area and check for kinks, leaks, or blockages in hoses.
• Test pump and sensor: Listen for the pump when a steam function is started. If silent, test the pump for voltage and continuity. Check the steam temperature sensor for correct resistance values.
• Replace components: Replace the steam pump, generator, or sensor as required using De Dietrich-specific parts.
