# Miele steam oven says there is no water

### The fastest diagnosis is the code

Check that the black suction hose inside the water container is present, seated and vertical — that is the maker's own first answer and it is free. If you have a reverse-osmosis system in the house, add a pinch of salt to the container: osmosis water can be too pure for the appliance's electrode to detect at all.

### Five causes, and the maker publishes all of them

The intake valve, the nozzle, the container, the suction hose inside it, and the conductivity of the water. That last one is the surprise: the appliance detects water electrically, and reverse-osmosis water can be too pure for it to see. The manufacturer’s own answer is to bypass the osmosis system or add a pinch of salt.

### The one that is not a repair

If the answer is the osmosis system, there is no part to fit and you get told that. It costs the visit and it stops an appliance being blamed for the plumbing.

The suction hose in the container

Out of position, missing or split.

Scaled. This maker publishes a condition specifically for a nozzle that needs descaling.

Water conductivity

Osmosis-treated water below the minimum the electrode needs. A documented cause, not a coincidence.

The feed pump

Dried out after a long period unused. Named by the maker, and a service call rather than something to retry.

With a full container in it

What it usually means

A full container and a message about water

Steam programs stopping part-way

Weak steam and long cooking times
