Thank you Luis and Juan for your comments. Following your suggestions, check the tachometer of the engine and the engine and cablera contacts, I will comment on the results.
As for the timing of the fault ... it does so as soon as the motor gives the first or second turn. This would rule out the possibility of a pressure switch failure due to excess foam in the centrifuge (which it does not do as it triggers error 7 immediately starts washing).
On the plate itself is new. A unit was set which should be programmed according to the apparatus in which they are to be installed. It is a "Phase 2"
Juan, the contacts were clean. The fault was (as Luis38 estimated) on the engine tachometer. Install a non-faulty motor and the washing machine operates normally. Thank you for giving me the solution and worrying about collaborating with me.
