Why is my Dishwasher not washing properly?

De Dietrich's dishwashers are of a high standard, with top A++ energy efficiency levels. If your dishwasher is not complying to standards, it may need to be descaled in order to remove potential lime-scale residue build up(this needs to be carried out at least once a year), or you may need to rinse your dishes before placing them into the dishwasher to ensure high quality cleaning.
