My washer did this a while ago. there's something stuck in filter . take the bottom plastic panel from the bottom the machine on the right hand side there's a black screw plug turn anti clock wise and pull out and take out what ever is blocking the filter. it was a 5p that was blocking mine. Becareful if there is a half a washed load in the washer cause lots of water will come out when you unscrew the drain plug.
