Good morning Tadeo60. It would not be ruled out if the fault comes from the programming card. If you have a tester, access the card where the cables are connected: .-light blue color of the micro safety switch .-orange color of the electronic pressure switch In this pair of terminals proceed to measure continuity being the main cable of the washing machine disconnected from the respective outlet. If there is continuity and the cables are in good condition; If the water level sensor pins are clean as well as the female pins of its connector, the source of the problem is what jomi (greetings) has indicated in its contribution. Not so much because of the magnet that is lost because that does not happen, but because the Reed Switch is damaged, except that the double connector where the two cables of the card converge to feed the two cables that are connected to the Reed Switch present in its terminals some degree of sulfation. That double connector is located in the corner where the main cable of the washing machine enters the upper body of the washing machine. But, if there is no continuity between both terminals at the card level where the cables are connected in light blue and orange respectively, the fault is in that circuit where the signal from the negative pole (for 5 vdc) that is related to the micro controller ( brain in the programming card) is open by some electronic component in trouble or a cold weld possibly present in that same circuit. In the latter case you should contact an electronic or TV technician for proper review. Review and comment on it. Thanks and regards.
