Water would not shut off when filling

I removed four hex screws from the top of the washer. I found the water level pressure switch and removed the dial. I turned it to remove it from the holding bracket. I removed both wires one at a time and placed them in the new switch one at a time so I wouldn't get them mixed up. I put the new switch in place and put the top back on using the hex screws. The dial was replaced. When I tested the dial I found that the dial did not match up to the water settings. They didn't even come close. Although the numbers were close on the switches, they were different. I had to remove the new switch and put the old one back on until I can locate the correct switch for my washer.
