Good morning Carlos. There is something contradictory in the approach you make or do not clarify when it happens. Initially you indicate that water enters and everything works well and then you end up letting it know that it is not full. Is it not filled in the rinsing stage after the soapy water has been removed and the intermediate spin has been performed? In the rinsing stage only the cold water solenoid valve intervenes. On the other hand, the pressure switch usually used by Samsung is the one that brings a small electronic card inside and where the power is through 3 wires: .-pink with DC signal (positive pole) for power supply. .-violet with DC signal (positive pole) for data exchange. .-orange with DC signal (negative pole). -.- Between the pink color cable and the orange color cable = 5 vdc -.- Between the violet cable and the orange cable = between 2.4 vdc and 3 vdc. Clarify exactly when the plastic tub is not filled in the washing machine. If you have a tester, check the voltages indicated above to see if they correspond from the programming card. Comment on this. Thanks and regards. ------------------- Edited on 08-18-2017 for the first time. Approach I: ** .- 2 hours ago From: carlos eliezer valdez Thank you very much for the help It does not fill in the rinsing stage ie after soaking the water and centrifuging as if the pressure switch remained stuck - ** Observations: Carlos: One possibility is that if in the washing stage both solenoid valves were programmed to work and assuming that the cold water solenoid valve had some setbacks such as: your coil is burned; - that its terminals are sulphated (dirty); .-that from the programming card does not reach phase signal; .-that the wicket rod at the entrance of the solenoid valve is dirty ..... would be sufficient reasons (each individually inclusive) so that the cold water solenoid valve does not respond in the rinsing step. And since the factory hot water solenoid valve does not activate, it implies that there will be no water entering the plastic tub at that stage. However, if the rinsing stage is activated without the presence of water and the impeller works without water, it is feasible that the electronic pressure switch is responsible if it is not physically the same as the one originally brought by the washing machine. You can gently blow through the end of the hose where it connects to the plastic tub in the direction of the electronic pressure switch to see if you hear any sound like clicking. You can repeat this procedure several times to see if you notice any failure in one of your attempts. In the same way it would be interesting to check if there is presence of tartar in the tube that protrudes from the plastic tub and where the semitransparent manguerite is connected. It must be completely clean so that the discharge of the air that presses the diaphragm into the electronic presoatato is carried out without problems. As the stage of the intermediate centrifugation is carried out, in theory and in practice the diaphragm would not remain stuck. What I would give for thinking that the fault could come from the programming card. What difference have you noticed between the new electronic pressure switch versus the old pressure switch?
