Dishwasher cleaning-performance checks

4 steps
  1. 01

    Reload so water can reach every surface

    User-level

    Space items as the rack guide shows and make sure no dish blocks a spray arm. Check that each spray arm can rotate freely before starting the cycle.

  2. 02

    Clean user-removable filters and spray arms

    Use caution

    Switch the appliance off and follow the exact model manual to clean its user-removable filter and spray arms. Do not reach into a pump or remove service panels.

  4. 04

    Escalate persistent poor cleaning

    Professional help

    If loading, the user-maintainable parts, program, and detergent are correct but results remain poor, use the manufacturer's support or qualified service rather than testing internal components.
