That hum you hear is the motor attempting to start , this can be caused by a number of isses, the most common would be “something” stopping the motor and macerator from turning, not a tough task to get into the pump, remove the lower impeller and using a torx 15 bit unscrew the upper pump assembly, keep going until u see a screen and metal “blade” and make sure it can turn freely, a bad control board or the motor itself would cause same thing

THank you for the info
