PROBLEM TO BE SOLVED: To decrease display sections, such as LEDs, and yet to enable the conventional display by adopting the constitution that the contents manipulated by an input means are inputted and displayed by the combinations of plural basic display sections and plural auxiliary display sections. SOLUTION: When a user first pushes a manipulation button 22A once in the case of the water level of, for example, a washing tank, a water level basic display section 22a is displayed. When the user manipulates a start button after displaying the same, a solenoid valve of a water feeder is opened only for the water feed time until a small volume water level is attained. The water of the small volume water level, i.e., 30L is fed to the washing tank. When the user feels the water is slightly little with this water feeding, the user pushes the manipulation button 22A once more. A water level auxiliary display section 22x is then displayed while the water level basic display section 22a is displayed. The water is then additionally fed to the washing tank until the water level of 30L+3L=33L is attained. The displays of 16 kinds at every 3L among 30L to 75L, i.e., the water levels, are displayed by the combinations of the four water level basic display sections 22a to 22d and the two water level auxiliary display sections 22x and 22y by repeating the similar manipulation thereafter.
