Hi;
Welcome to the forum.
When you say "hot", are you referring to temperature, or that the electrical circuit is complete? Have you taken off the generator cover to observe what is happening when the advance button is pushed?
It may be a circuit board problem, and the motor could be out of sync. You should give Bradley a call.
If the generator is just making a clicking sound, you may have a jam, or a couple of gear teeth may be damaged. If you bisquettes are old, they could be damaged by humidity, and have swollen. This can cause jams. If you have a jam, or something is causing too much resistance, the motor will not make a complete cycle, and will only rotate partially, then reverse and return to its "ready" position.
