GOOD EVENING You must defeat both right and left walls, attached to the back with screws, see screw nuts, and then you lift the top for access to the security door, disconnect machine for your safety and your proches.Cordialement Jean-Paul
thank you for your answers Jean-Paul and Lachignole, I am finally here. to meet Lachignole: the machine blows a fuse when I turn it on. I unplugged the resistance: such I unplug the engine: the same and I see a spark at the famous security door.
Now that I managed to get out I measure the continuity between its 3 cards: I find the infinite everywhere ("1" on my tester-esh-2M). is this possible that the short circuit takes place just when I put the then current or DC is on its power supply wire and then it would be the small box located at the finish of the inside of the machine back side. measurement made on it: it goes down to 200k and it goes back to 600kohms. what do you think, thank you
the little box after the power cord is a filter, it is not an issue since it is always turned on, the security door might be a leak to ground, normally you should find a resistance ohmmeter 10 20 K ohm between terminals 2 of the 3 door contact is infinite everywhere if the door contact is HS
