a disfunctional Hotpoint WF840 Ultima Super Silent?

My machine has started to pour water out through the detergent tray during every cycle. It then proceeds to stop with 1 minute to go on the clock and will not finish the cycle. I am having to turn it off completely, then re start it on a spin cycle to get rid of the water. My floor is flooding EVERY time I do a wash! It's driving me crazy.

Any ideas?
