Definitions

  • the technical purpose which forms the basis of this invention is to propose a method for washing kitchenware articles which might break as a result of sudden cooling that overcomes the above-mentioned disadvantages of the prior art.
  • the method therefore comprises acting on the pump 3 rotation speed or on the geometry of the conduit 49 which draws the new washing liquid from the bottom of the washing compartment 2 so that it can again be sprayed against the kitchenware articles placed in the washing compartment 2.
  • the first and/or the second operating sub-step is/are performed in a predetermined interval of time.
  • the third washing step may comprise a new step of heating the washing liquid being used (initially introduced at a temperature close to ambient temperature).
  • said new heating step is carried out for a predetermined interval of time. Appropriately (see C1 in Figure 2 ) the new heating step brings at least the first washing zone 21 to a temperature of between 60°C and 70°C (advantageously around 65°C).
  • the dishwasher 1 comprises a first rack and a second rack 5, 6 which are located in the washing compartment 2.
  • the first rack 5 comprises the first positioning means 7 and is obtained above the second rack 6 which in turn comprises the second positioning means 8.
  • the first rack and the second rack 5, 6 can normally be removed from the washing compartment 2. During washing the first and second racks 5, 6 are inside the washing compartment 2.
