Error codeF04
ApplianceSteam Oven
Quick answer
F04 means the power supply was interrupted while a programme was running. Check progress, set a new duration and press Start/Stop.
Model compatibility
Miele reuses codes across series and model years, so F04 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
Power supply interrupted during a programme.
A Miele steam oven or combination steam oven shows F04 after the power supply drops out while a programme is running.
What to do
Check how far the cooking has progressed.
Enter a new cooking duration if necessary.
Press the Start/Stop button to continue the programme.
Miele’s operating instructions for the DGC 7450 steam combination oven describe the matching display message, “Power cut – process cancelled”. It says a brief power cut stopped the current cooking programme. Their remedy adds one step: switch the oven off and back on, then restart the programme.
Related codes
If the display shows F235 instead, that is an electronic module fault, not a power cut. F20 is a different message, about the compartment failing to warm up at the start of heating.
