Check operation of pressure switch. This switch tells the system that there is water in the tub and allows it to proceed to agitate. The switch itself is behind control panel but you can lightly blow into the hose leading up to it. Remove hose from side of tub and see if you can get the switch to flip by softly blowing into the hose. If power is on and timer is set to fill, it might begin to agitate at this point, so keep your hands away from the motor and pulley assembly. If it does try to agitate the switch is functional. It is best to check this while unplugged, then reassemble and try the unit. Check the hose for blockage, especially where hose connects to tank, lint from clothes can clog this causing overfilling.
