PROBLEM TO BE SOLVED: To provide a washing drying machine capable of reducing disadvantage to daily life by warning the disadvantage prior to stopping operation at an early time. SOLUTION: A control section 19 calculates the temperature rising rate of air from the temperature of the air fed to a water tank 12 and a rotary tank 13 after being heated by a heater 17. The control section 19 detects an advancing degree of clogging of a pathway through which the air flows by calculating the temperature rising rate of the air and changes warning display lit in a display panel 18 according to the advancing degree of the clogging. Thereby the advancing degree of the clogging of the pathway through which the air flows can be perceived gradually and at an early time. COPYRIGHT: (C)2009,JPO&INPIT
