Abstract

A method of washing ware in a dishwasher includes the steps of starting a dishwashing program; automatically locking the door and keeping it locked for the whole duration of the dishwashing program; and dosing at least 100 mg of active enzyme into the washing chamber. The dishwasher includes a washing chamber and a door to close the washing chamber.

What is claimed is: 
     
         1 . A method of washing ware in a dishwasher wherein the dishwasher comprises a washing chamber and a door to close the washing chamber, the method comprising the steps of:
 i) starting a dishwashing program;   ii) automatically locking the door and keeping it locked for the whole duration of the dishwashing program; and   iii) dosing at least about 100 mg of active enzyme into the washing chamber.   
     
     
         2 . A method according to  claim 1  comprising the step of dosing at least about 120 mg of active enzyme into the washing chamber. 
     
     
         3 . A method according to  claim 1  wherein the dishwashing program is a short program having a duration of less than about 1 hour. 
     
     
         4 . A method according to  claim 1  wherein the dishwashing program comprises a main-wash and the temperature of the washing liqueur of the main-wash is less than about 50° C. 
     
     
         5 . A method according to  claim 1  wherein the dishwashing program has a duration of from about 10 to about 40 minutes and the temperature of washing liqueur of the main wash is about 45° C. or less. 
     
     
         6 . A method according to  claim 1  wherein the dishwashing program comprises a main-wash and the main-wash uses about 5 liters of water or less. 
     
     
         7 . A method according to  claim 1  wherein the dishwasher program uses less than about 1 kW. 
     
     
         8 . A method according to  claim 1  wherein the active enzyme is delivered into the main wash. 
     
     
         9 . A method according to  claim 1  wherein the active enzyme is delivered as part of a detergent composition. 
     
     
         10 . A method according to  claim 1  wherein the detergent composition is in powder, liquid, gel or unit-dose form. 
     
     
         11 . A method according to  claim 1  wherein the detergent composition is in unit-dose form and the weight of the unit-dose is about 15 grams or less. 
     
     
         12 . A method according to  claim 9  wherein the detergent composition comprises a perfume wherein the perfume comprises at least about 10% by weight of the perfume of blooming perfume ingredients selected from the group consisting of: ingredients having a boiling point of less than about 260° C. and a logarithm of octanol/water partition coefficient (ClogP) determined by the fragment approach of Hansch and Leo of at least 3. 
     
     
         13 . A method according to  claim 9  wherein the detergent composition has a pH of at least about 10 as measured in about a 1% weight/volume aqueous solution in distilled water at about 20° C. 
     
     
         14 . A method according to  claim 9  wherein the detergent composition comprises bleach. 
     
     
         15 . A method according to  claim 9  wherein the enzyme is selected from the group consisting of amylase, protease and a mixture thereof.
