By using rinse aid, the dirt particles likely to be retained in the rinsing water is removed by means of water without clinging on the surfaces of the washed items. Rinse aid is conveyed to the washing tub by means of a dosing unit.
  • the amount of rinse aid can be determined automatically or by the user.
  • the rinse aid dosing process is interrupted in case a safety issue arises with the dishwasher or its door is opened by the user during washing. When the washing cycle continues afterwards, the rinse aid is dosed from the very beginning, or rinse aid dosing is not performed at all. This leads to use of insufficient or excessive amount of rinse aid. Using insufficient rinse aid decreases the drying performance, and using excessive rinse aid causes forming of spots on the kitchenware.
  • EP2563202 mentions a household appliance capable of dosing cleaning agent suitable for parameters selected by the user.
