jessica,
looks like there might be something stuck in the filter, on the bottom of the machine you will see a kick plate which can be removed with a screwdriver, go on your knees and you will see where to poke the screwdriver to prise off the bottom, now pull out the machine away from the wall so you can tilt it back a bit so you can put a pan or something
under the plug that you have to turn anti-clockwise to open up as to collect the water that will come out.
hope this helps.
