Abstract

The present invention relates to a method for controlling a dish washer, and more particularly, to a dish washer and a method for controlling the same, in which a contamination level sensor is made to measure a contamination level of a washing tub, accurately.

The method includes a water supplying step for supplying washing water to an inside of a dish washer, a washing step for washing dishes by spraying the washing water to the inside of the dish washer, a pausing step for the controller to control the dish washer in the washing step to pause a washing course for a preset time period temporarily, and a re-washing step for carrying out the washing course which is paused again after the pausing step.

Claims

1. A method for controlling a dish washer comprising:

a water supplying step for supplying washing water to an inside of a dish washer;

a washing step for washing dishes by spraying the washing water to the inside of the dish washer;

a pausing step for the controller to control the dish washer in the washing step to pause a washing course for a preset time period temporarily; and

a re-washing step for carrying out the washing course which is paused again after the pausing step.

2. The method as claimed in claim 1, wherein the pausing step includes a contamination level measuring step for measuring a contamination level of the washing water.

3. The method as claimed in claim 2, wherein the controller controls the washing course according to the contamination level measured at the contamination level sensor in the contamination level measuring step.

4. The method as claimed in claim 1, wherein the controller performs the pausing step by turning off the dish washer.
