Error codeF94
ApplianceSteam Oven
Quick answer
F94 on a Miele steam oven means the float switches in the water container have stuck. The manual covers cleaning, descaling and checking the water supply.
Model compatibility
Miele reuses codes across series and model years, so F94 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 thiscode means
Float switches in the water container are stuck; on the microwave model, water inflow may also be insufficient.
F94 on a Miele steam oven points to the water container. The float switches that measure the fill level have stuck. The manual says this can happen when the oven goes unused for a long time with water still in the container.
Which models
Miele publishes F94 instructions for two types: the combination steam oven and the steam oven with microwave. The generation is not stated.
Combination steam oven
Take the container out after each use by pushing it up slightly. Empty it and dry the compartment.
Rinse the container by hand or in the dishwasher, then dry it with a cloth.
To descale, fill it with lukewarm water, add 1 descaling tablet and leave it for about 10 minutes.
Clean the float switches with a small bottle brush and rinse the container well.
Never remove the lids on the float switch casings. They are friction-welded, and taking them off makes the container unusable.
The manual adds that the control panel closed with little or no water arriving can mean a trapped or kinked inlet hose. Close the supply valve, straighten the hose, open the valve and restart.
Steam oven with microwave
Empty, rinse and dry the container, descale it and brush the float switches the same way. Open the water supply valve and restart. If the intake valve leaks, switch the oven off, close the integrated valve and contact Miele Customer Service.
