DIY Possible

Safe Checks You Can Do

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

    Purchase replacement charcoal filter

    Order the correct Miele charcoal filter for your hood model. Check your manual or the Miele website for the part number.

    Miele DKF charcoal filters are model-specific — using the wrong one won't fit.

  2. 2

    Replace the filter

    Open the filter compartment (usually behind or above the grease filters). Remove the old charcoal filter and insert the new one.

    Some Miele charcoal filters can be regenerated in the oven (check if yours is a "regenerative" type).

  3. 3

    Reset the indicator

    Hold the charcoal filter button for 3 seconds with the fan running to reset the hour counter.

    If your hood has a DKF regenerative filter, regenerate it in the oven at 200°C for 4 hours instead of replacing.

When to Call a Professional

Contact a qualified Miele technician if:

  • Indicator board problem
  • Recirculation duct seal broken (odors bypass filter)
