Keep your dishwasher working in top condition with this 7 step guide!
Always check that the spray-arm “spinner” is free to rotate all the way around, before starting your machine. It is very common for the cutlery to catch this, and you end up with partly rinsed dishes, and cups with sandy deposits in. If yours has a top tray for cutlery (like some MIELE and a few other models), check that one too.
Use one of the dishwasher cleaners every few months. These usually need a hole pierced in the bottle, or a tab removed, and they are then jammed in between a couple of tray prongs. Put it on the wash cycle as recommended on the label.
