Portable Dishwasher Repair

Water fill is OK. When in any wash cycle the dishwasher washes and drains the water at the same time, and continues to wash when water is emptied out totally until wash cycle is complete:confused:. Any idea as to what parts I need to fix this? Thanks!!

Is the water being pumped out or is it being siphoned out?

How is the drain set up on this DW?

It’s a portable floor model DW. The hose is a double hose connected to a coupler that attaches to sink faucet. One hose is for filing and the other for draining. When you start cycle it fills the bottom the way it is supposed to, then when it starts to wash the water armature spins and sprays the way it is supposed to, but at the same time water is I assume being ?pumped? out. It empties and the wash cycle continues to run till it ends and the rinse cycle begins as above with the same thing happening.
