Definitions

  • the invention relates to a dosing system for a dishwasher with an optical communication between the dosing system and the dishwasher.
  • Machine dishwashing and washing agents are available to the consumer in a variety of forms. These automatic rinsing and washing agents are typically offered to the consumer in solid form, for example as powders or as tablets, but increasingly also in liquid or gel form. For some time now, the main focus has been on the convenient dosing of rinsing and washing agents and the simplification of the steps necessary for carrying out a rinsing or washing process.
