Complete Miele Dishwasher Maintenance Guide

Miele dishwashers are engineered for decades of reliable service, but they still require regular maintenance. This guide covers everything from daily habits to annual tasks that preserve performance.

After each cycle, leave the door slightly ajar to allow moisture to escape. This prevents odors and reduces stress on door seals. Wipe the door gasket monthly with a damp cloth to remove food residue.

The filter system requires weekly attention. Remove the filter assembly from the bottom of the tub and rinse under running water. Use a soft brush to remove stubborn debris. A clogged filter is the most common cause of poor cleaning.

Spray arms can become clogged with hard water deposits or food particles. Remove them monthly and clear each spray hole with a toothpick. Rinse thoroughly before reinstalling. Blocked spray arms result in poorly cleaned dishes.

Run a cleaning cycle monthly using Miele's machine cleaner or a dishwasher-safe descaler. This removes grease buildup and mineral deposits from internal components. Run the cycle with an empty dishwasher.

Check the drain hose connection annually. The hose should loop high before connecting to the disposal or drain to prevent backflow. A low drain loop can allow dirty water back into the tub.

Hard water areas require more frequent descaling. Signs of hard water include white film on glassware, reduced cleaning performance, and visible deposits on the interior. Consider a water softener if problems persist.

The door latch mechanism should operate smoothly. If you notice resistance or hear grinding sounds, the latch may need lubrication or replacement. Do not force the door—this can cause more damage.
