The washing machine will overflow, flooding water

ive included a solution to a similar problem that i solved earlier this week, i hope you find this helpfull...

"
I am assuming this is a top load washing machine.... the load size selector button has a hose attached to the back of it. This hose goes down to an overflow box mounted to the side of the tub. This tube often gets clogged and the machine cannot tell where the water level is. 1) dissconnect the tube from the level selector switch and ( w/it unplugged ) attach another tube to it and blow into it. you should hear a clicking sound. this means your level selector switch is functioning properly. if it does not click then it needs to be replaced. 2) dissconnect the tube from the level selector switch and ( w/it unplugged ) blow into the tube and you should hear air going into the tub, ( this is best performed with water in the tub ( bubbles ) )....hope this helps
