Washing-time compensating method of a washing machine

A washing-time compensating method of a washing machine comprising the steps of:

• setting a speculative total washing time required for a washing operation in accordance with a washing condition set by a user in view of a program internally stored;
• sensing a quantity of water supplied up to a predetermined water level within a washtub;
• checking a water supply time taken up to said predetermined water level in said sensing step, calculating a water supply time up to a water level required for the washing operation by using said water supply time as a reference, and producing a total water supply time in accordance with the number of supplying the water throughout the overall washing operation;
• executing the subtraction of the actual total water supply time in said producing step and speculative total water supply time in said setting step to calculate an additional water supply time;
• and
• adding said additional water supply time to the current total washing time to compensate for said total washing time,
• whereby said washing operation is carried out in accordance with the washing time obtained in said compensating step.
