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 Brew Unit

    Remove, clean thoroughly, lubricate seals, and reseat.

    Compacted grounds are the #1 cause.

  2. 2

    Clear the Grinder

    Empty beans, vacuum the chute, remove any foreign objects.

    Check for stones in the beans.

  3. 3

    Adjust Grind Setting

    Adjust only while the grinder is running.

  4. 4

    Power Reset

    Turn off at mains for 10 minutes.

    Motor thermal protection needs time to reset.

  5. 5

    Test with Light Program
