A method to use an automatic machine to wash kitchenware items (11, 12, 13); the automatic machine comprising: - a rigid support frame, - one or more covering panels fixed to said rigid support frame, - a compartment defined by said covering panels, - a washing chamber disposed inside said compartment and provided with a bottom wall tilted with respect to the horizontal axis by an angle (α) higher than 3° in order to make the washing water flow towards an outlet, - a rotary drum disposed inside the washing chamber and provided with axis of rotation, - at least one nozzle provided with at least one dispenser point disposed inside said washing chamber, - an encoder to count the number of revolutions of the rotary drum, - a control unit connected to the encoder and adapted to compare the number of revolutions detected by the encoder with a preset number of revolutions (Np), - a stop device connected to the control unit and encoder, said stop device being configured to stop, - a timer connected to the control unit and stop device, said timer counting for a preset time interval and being configuration to control the stop device, the method comprises the following steps: - load the kitchenware items (11, 12, 13) into the drum, in loading position wherein the kitchenware are situated under said axis of rotation; - start the rotation of the drum wherein the encoder counts the number of revolutions of the rotary drum and the control unit compares the number of revolutions detected by the encoder with the preset number of revolutions (Np), - stop the rotation of the drum, my means of the stop device, when the number of revolutions detected by the encoder is equal to the preset number of revolutions (Np) minus half a revolution (N = Np - 1⁄2), in such manner that the kitchenware items (11, 12, 13) are situated above the axis of rotation of the drum to drain water, - count the preset time interval, by means of the timer, - release the rotation of the drum, after the preset time interval, to make a last half revolution of the drum and bring the kitchenware items back to the loading position. - a rigid support frame, - one or more covering panels fixed to said rigid support frame, - a compartment defined by said covering panels, - a washing chamber disposed inside said compartment and provided with a bottom wall tilted with respect to the horizontal axis by an angle (α) higher than 3° in order to make the washing water flow towards an outlet, - a rotary drum disposed inside the washing chamber and provided with axis of rotation, - at least one nozzle provided with at least one dispenser point disposed inside said washing chamber, - an encoder to count the number of revolutions of the rotary drum, - a control unit connected to the encoder and adapted to compare the number of revolutions detected by the encoder with a preset number of revolutions (Np), - a stop device connected to the control unit and encoder, said stop device being configured to stop, - a timer connected to the control unit and stop device, said timer counting for a preset time interval and being configuration to control the stop device, - load the kitchenware items (11, 12, 13) into the drum, in loading position wherein the kitchenware are situated under said axis of rotation; - start the rotation of the drum wherein the encoder counts the number of revolutions of the rotary drum and the control unit compares the number of revolutions detected by the encoder with the preset number of revolutions (Np), - stop the rotation of the drum, my means of the stop device, when the number of revolutions detected by the encoder is equal to the preset number of revolutions (Np) minus half a revolution (N = Np - 1⁄2), in such manner that the kitchenware items (11, 12, 13) are situated above the axis of rotation of the drum to drain water, - count the preset time interval, by means of the timer, - release the rotation of the drum, after the preset time interval, to make a last half revolution of the drum and bring the kitchenware items back to the loading position.
