My dishwasher is the Fagor LVF65IT model and the problem is that the plate (printed circuit board) does not light,

I copy the message again about my problem with the dishwasher and attached the photos of the printed circuit if someone can help me: My dishwasher is the model Fagor LVF65IT and the problem is that the plate (printed circuit) does not turn on, nor is unmoved, My dishwasher is the model Fagor LVF65IT and the problem is that the plate (printed circuit) does not turn on, I understand that I should turn on some lights and at least give me breakdowns, but not unmoved, I checked with the tester and I have seen that there is no current to the circuit, failure phase and therefore do not get 220V, then I put a cable and I've got direct current to the input of the board, but even putting I stream directly with a cable to ensure that it is 220, the plate remains unmoved, does not work at all, I think that the circuit is broken but I'm not sure since I have taken and not see any black part as they had been burned, it is all clean and looks perfectly fine, do you know someone who may be? What I can say with certainty that the printed circuit is damaged, or there may be another reason? What should I Do any more test? Thanks again ![](//blob.todoexpertos.com/uploads/md/cba00249e9ecfd1c0655145bfc9c91c3.jpg)

Could be the internal fuse of the transformer (large square blue) or the relay (gray rectangle clear just below) Starts following the tracks where you connect the 220V, I guess it is the white plug. And you should take directly, or by passing the relay to the transformer blue. You'll see that it has two legs to a side and two legs to another. If you have a multimeter test to see if there is continuity between the two legs of each side. I should give you a resistance of 100 to 1000 ohms in the primary side (where it enters the 220V) and a resistance of 1 to 100 ohms in the secondary. What tends to happen is that it melts the internal fuse of the transformer and the primary is open circuit. I days that has passed. If this is a good look at the relay it is best to desoldarlo and with a source you 12V or a 9V battery sometimes works too, you give him power and with the tester connected in the legs of output of 230V should stop passing current when you give 12V to the coil and to cut off current when it is not das. I think those two things are the most likely, if that is not it and no one else brings ideas I would go looking for the fault to see where the current is cut off. But that is dangerous, given that you have 220V on board, and if you mess up you can melt something or receive a discharge.
