Hi Maria: as the comrades tell you (greetings to both of you) you can have your pressure switch damaged (photo) or you can have the hose that covers it and gives the tub covered, do this, if you put the washing machine down, at a next to the tub you will see a thin cuff, which overlooks the top (washer top) remove the cuff, and where that cuff comes is the pressure switch, disconnect it from the side of the pressure switch and blow into the hose (the air must pass free) if you feel that it does not come out, put a long wire and with that it is uncovered, blow again and make sure that it passes free, if I pass free at the first, then blow on the pressure switch very softly you will hear three cicks that it means that your pressure switch works if you don't change it a greeting and comment
