how can i fix?

yes your anti flood switch has activated, what happens is water from the machine goes down two tubes at the bottom of the inside of the door and fills a small pool in the base of your washer which then floats the anti flood switch.
simply remove the metal cover that is at the front of the machine under the door and use some kitchen paper to absorb and remove all the water in the pool.
this will lower the float switch back to the bottom and -bobs your uncle- this will fix it.
remember to turn of at the mains before you begin
good luck
