My pump motor won’t start anymore

In almost every case this means that you need to replace the motor capacitor. A espresso machine motor is always a single phase motor, so it requires a motor start capacitor to function. If this capacitor is broken your motor won’t start. You can measure your capacitor with a multimeter if it is indeed bad. If that is the case you need to replace the espresso machine motor capacitor. Always make sure that you have the correct amount of microfarad, if that is too low your motor won’t start either.
