detergent may break the plastic parts. For the dilution, follow the instruction enclosed with the
detergent). When a diluted neutral dishwashing detergent is used, wipe the cabinet or accessories
thoroughly with a cloth soaked in clean water. Then wipe the cabinet or accessories unit with a dry cloth
to eliminate the moisture.
