Safe Checks You Can Do

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

    Clean the Spout

    Remove the dispensing spout (if removable) and clean all openings with a pin or small brush.

    Soak in warm water to dissolve dried coffee.

  2. 2

    Run Cleaning Program

    Run the automatic cleaning program with Miele cleaning tablets.

    This flushes internal lines.

  3. 3

    Descale

    Run the descaling program — scale can restrict internal tubing.

    Descaling addresses both dispensing and heating issues.

  4. 4

    Clean Brew Unit

    Remove, clean, and lubricate the brew unit.

    Worn seals can cause low pressure.

  5. 5

    Power Reset

    Turn off at mains for 5 minutes.

    The pump controller may need to reinitialize.
