That sentence is Miele’s own, read off its published support page for this condition rather than worked out from the outside. Everything below it — what the condition covers and what is worth doing first — is ours, written from what this equipment does in Miami kitchens. ### What this block of conditions is about One block covers the wall ovens, the combi-steam ovens, the speed ovens and the warming and vacuum-sealing drawers, because Miele builds them on one control family. The steam side adds a set of its own about water: the intake valve, the nozzle, the container and the conductivity of the water itself. ### What it covers What a published cause names is a circuit rather than a component, which is the single most useful thing to know before anybody orders a part. This one covers: - The fill level inside the water container is measured by float switches; see figure. The message - May be displayed if the appliance has not been used for an extended period and there is still water in the water container. This can cause one or both float switches to get stuck. - The lids on the float switch casings are friction-welded. - If you remove them, the water container will become unusable. The float switches might fall out of the float switch casings. - Never attempt to remove the lids from the float switch casings. - For thorough and gentle descaling of the water container, genuine Miele descaling tablets that have been formulated for use with your appliance are recommended. - Insufficient or no water flows into the water container when the control panel is closed. No water intake. The water inlet hose is trapped or kinked. - No water intake. Insufficient or no water flows into the water container when the control panel is closed. The water supply valve has not been opened. - The water intake valve is leaking. ### Worth trying yourself, in this order - Clean the water container: - Remove the water container after each use. To do this, push it upward slightly as you take it out of the appliance. - Empty the water container. Water can drip into the container compartment when the water container is removed. - Dry the compartment. - Rinse the water container by hand or in the dishwasher. The water container is dishwasher-safe. - Dry the water container with a cloth to prevent limescale. - Descale the water container: - Rinse the water container with clean water. - Fill the water container with lukewarm water. - Add 1 descaling tablet to the water container. - Leave the descaling solution to work for approx. 10 minutes. - Clean the float switches with a small bottle brush. - Rinse the water container thoroughly with clean water. - Close the water supply valve of the domestic water supply that is connected to the appliance. - Check the water inlet hose and straighten it out. - Open the water supply valve. - Restart operation. - Open the water supply valve of the domestic water supply. - Restart operation. - Switch off the appliance. - Close the integrated water intake valve inside the built-in appliance. ### Then what Most of the oven and steam-oven conditions on this make are genuinely an owner’s job — twenty of the twenty-five Miele publishes — and most of them are about water or about something in the cavity rather than about electronics. If yours is a combi-steam oven, assume scale until proved otherwise: the water here is hard, descaling is the maintenance this appliance actually needs, and a machine that is descaled on schedule reports very little. Miele publishes this one for the ovens, steam ovens and the drawers — that is ovens, steam ovens and drawers on this site. The [full Miele archive](https://mielemiami.support/error-codes/) has the other conditions, searchable, and on this make the same number appears on more than one machine roughly a third of the time, so the appliance above is part of the answer. We repair this equipment across Miami-Dade, Broward and Palm Beach.
