DAILY CLEANING 1. Turn dishwasher and wall switch OFF. 2. Remove the overflow to drain wash tank. 3. Remove scrap screens and wash pump inlet screen. Rinse thoroughly to make sure that they are clean. Do not bang or beat them on the side of sink or other hard objects as this will eventually cause them to break or bend thus causing them to fit or work properly. - Page 14 MAINTENANCE MAINTENANCE Before carrying out the cleaning and the maintenance operations, turn off the main disconnect switch for the equipment. Do not use corrosive products such as sodium hypochlorite (bleach), acids, steel wool or steel brushes to clean the inside and the outside of machine. The presence of calcium and magnesium salt in water can compromise machine performance.
