A cooking equipment includes an oven cavity (2); at least one energy source (3), operable to provide energy to food placed inside the oven cavity (2); a plurality of sensors (5), configured to provide respective measurement signals (STC, STWR, STWI, STE, STF1, ..., STFN, SH), indicative of respective quantities relating to a cooking process for cooking food in the oven cavity (2); and a control device (8), having at least one cooking program stored therein and configured to drive the at least one energy source (3) in accordance with the cooking program, based on the measurement signals (STC, STWR, STWI, STE, STF1, ..., STFN, SH) from the sensors (5). The cooking equipment also includes a storage unit (13), which contains first data (14, 15) indicative of energy required to carry out the at least one cooking program; and a processing unit (11), configured to determine, for the cooking program, an expected energy consumption level (EECL) from the first data (14, 15) and an actual energy consumption level (AECL) and to detect the presence of a malfunction based on a comparison of the expected energy consumption level (EECL) and of the actual energy consumption level (AECL).
