Caple oven shows an error when using steam-assisted or moisture functions (on compatible models); steam generation stops.

Safety first: Disconnect power and allow any steam components to cool before opening covers.

• Check water tank: Ensure the water tank is filled to the correct level and properly seated in its compartment. Clean the tank contacts if present.
• Inspect steam inlet: Check the steam outlet/inlet in the cavity for blockages from food debris or limescale. Clean gently with a descaling solution if allowed by the manual.
• Test steam heater: Access the steam generator (usually behind or below the cavity) and test the heater element for continuity. Replace if open circuit.
• Check level sensor: If the model uses float or electronic level sensors, inspect for free movement and clean any scale build-up.
• Descale system: Run a descaling cycle if the manual provides one, using an approved descaler.
