PROBLEM TO BE SOLVED: To provide an automatic ice-making machine, detecting abnormality of a water feed valve. SOLUTION: A jet type ice-making machine 10 includes: a water-cooled condenser CD, a cooling water feed pipe 36 where cooling water is circulated, a water feed valve 38 adjusting the flow of cooling water in the cooling water feed pipe 36, and a refrigerant temperature detecting means 32 for detecting the refrigerant temperature at an outlet side of the compressor CM. The cooling water feed pipe 36 includes a cooling water temperature detecting means 42 for detecting the temperature of cooling water heat-exchanged with the refrigerant of the water-cooled condenser CD. When the detected cooling water temperature of the cooling water temperature detecting means 42 at the completion of making ice is lower than a preset reference temperature, a control means 40 determines abnormality of the water feed valve 38 and causes a display means 44 to display abnormality.
