Because you say all was working for a while before this latest event, it will be the supressor that has failed, they are generally in the foot control (some machines have them in the main body near the power inlet) and it needs to be removed, it only stops interference to Radio & TV and is not necessary for correct function...............your nose will tell you if it is in foot pedal or inside the machine..
Unplug from mains, undo cover/s and find the electronic looking item which is cracked, burnt & probably oozing brown goo and smelling like burned plastic only worse.... Simply remove this from the circuit, clean the region with some denatured spirit, methanol or similar, wait until completely dry and re-assemble....this should fix the problem of the machine "running on" by itself....as to whether you have done a good job of the initial electrical repair, only you will know that.
By the way, how's the dog ? Guess the machine was not plugged in at the time !!

If you can get acess to or borrow another foot pedal to try I would do this first any of the Activa, Artista range fit to try. The fault may not be in the foot pedal but in the main CB of the machine. This can give a fualt of lights on but no motor drive. In this case the board would need replacing by a technician. Hope this may help.

There is a thing called a suppressor which is normally located in the foot control which has fused, you need to open the foot control and you should see a a small thing that looks liuke a fuse connected to the two terminals which you need to take out and discard because you don't need it any more, if you don't have on in the control then it will be on the motor which means you will have to take it in for repair.
