Washing machine model no SF-160GJ have problem show F9 at the screen

It will not let you unlock the door because the machines full of water?--the machine will not finish its cycle because the vacume switch is still detecting water. The water will not drain because the pump is blocked with something , probably a wire from your underwire bra, all you can do is undo a pipe undernieth and let the water drain away and take the pump to bits? There may be an inspection cap somewhere on the front at the bottom.

Hope helps.
