Water won't turn off

Sounds like the pressure switch is not working.two reasons for this the tube that operates the switch to turn off the water sits outside the drum and is normally full of air.as the drum begins to fill it increases the air pressure in the tube to the point where it trips the switch to turn off the water input.if the tube fills with water it will not operate the turn off part of the operation.you either check the tube for water by open inning the top and disconnecting the rubber hose from the drum and empty out any water.this should make it operational again.if not then it is probably the switch itself.easily replaced by parts obtain through eBay for your model machine.not difficult to do, tutorials on YouTube are available on this topic.
