Answer to continue safely

Is it safe to keep using?

Yes. Normal cooking modes are not affected. Only the pyrolysis self-clean function is disabled.

Can I reset the code?

No. No — the underlying cause (element, seal, or lock) needs to be repaired.

When to stop immediately?

Stop if you notice: F23 is persistent — pyrolysis needs repair, Other F-codes appear during normal cooking.

Symptoms You May Notice

"F23" on the display

Appears when pyrolysis self-clean is started.

Pyrolysis cycle aborts

The self-clean cycle starts but stops before reaching full temperature.

Normal cooking may still work

Standard baking and roasting modes often function normally.

Possible Causes

1

Heating element partially failed

An element works for normal cooking but cannot sustain the extreme heat of pyrolysis.

Requires Professional
2

Door seal deteriorated

The pyrolysis-rated door gasket is worn, allowing heat to escape.

Requires Professional
3

Door lock mechanism problemy

The door cannot lock securely, which is required for pyrolysis to proceed.

Requires Professional

Safe Checks You Can Do

These checks are safe for homeowners. No disassembly required. Do not remove panels or access internal components.
  1. 1

    Check the door seal

    Inspect the rubber/silicone gasket around the oven door. Look for cracks, gaps, or areas where it has flattened and no longer makes contact.

    A worn seal lets enough heat escape that pyrolysis temperature cannot be maintained.

  2. 2

    Check door closure

    Make sure the door closes fully and the lock engages. The oven will not run pyrolysis with a door that does not lock.

    Try the door lock manually — you should hear it click into place.

When to Call a Professional

Contact a qualified Miele technician if:

  • Element cannot sustain 480°C
  • Door seal needs replacement
  • Door lock mechanism failed
