Water did not shut off at water level setting

The replacement switch arrived exactly on the number of days I was advised when I ordered it. After opening the lid of the washer, the old water level switch was turned 1/4 turn, and it pulled right out (after unplugging the electical wires from the switch). I replaced the rubber water tube ann plugged it into the new water level switch. Then installe the switch, and closed up the washer. Not hard at all.
