Error code F10

Appliance Steam Oven

Quick answer

F10 flags a water inlet fault on a steam oven. The manual names an idle pump, a displaced suction hose and osmosis water.

Model compatibility

Miele reuses codes across series and model years, so F10 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

Water inlet fault; feed pump dried out, suction hose problem, or osmosis water.

The display of a steam oven or combination steam oven may show F10 along with a water inlet fault. The manual gives three explanations.

At a glance

Code	F10
What it means	Water inlet fault; feed pump dried out, suction hose problem, or osmosis water.
What you can check	Check the black hose in the water container is upright, fitted correctly and not loose. If you use an osmosis system, switch it off if possible, or add a pinch of salt to the container water.
When to call a technician	A dried-out feed pump needs a technician, as does a hose that is missing, leaking or cracked. Book a visit if refitting the hose or changing the water does not help.

Unused for ages: the feed pump has dried out. This one needs Miele Customer Service.
Suction hose: the black hose in the water container is not fitted correctly, is not upright, is loose or is absent. Refit it and straighten it. A hose that is missing, leaking or cracked must be replaced, so contact Miele Customer Service.
Osmosis water: an osmosis system lowers the water conductivity. Hardness of at least 1 °dH (30 µS per cm, 15 ppm) is needed for the electrode in the steam generator to sense the water, and without it F10 (no fill level) appears. See if the system can be turned off, or put a pinch of salt in the water container.

Compare with these codes

F12: the water intake valve is closed or the filter is blocked.
F11: water cannot drain from the steam generator.
