I have a GE Dishwasher that is also about 9 years old. Model number GSD4030z02WW. When I start the wash cycle, I hear the water as if it is about to wash and suddenly it drains off the water. I let it run through a complete cycle, and I have liquid detergent just sitting in the machine afterwards, and the dishes are still dirty. It doesn't look like water is coming in the machine at all.

You're certain the dishwasher actually fills to the proper level? (which is usually to just below the heating element)
If it IS filling properly...
There is a 'flapper' valve in the pump assembly which opens or closed to change between wash and drain. That valve is actuated by an electric solenoid on the side of the pump. There is a spring that returns the flapper to the wash position once the water has been drained out.
It may be possible that the return spring has fallen off or broken or flapper valve in the pump is just not sealing properly, only allowing the pump to be in drain mode.
Someone will likely need to inspect that mechanism to see what is actually going on if the pump is prematurely draining the water from the tub.
** If what you are saying is right, then there should not be any detergent left in the bottom of the unit **
I don't know what you mean by that. If there's no water being sprayed, there is nothing to wash the detergent away so whatever was there to begin with would remain (but possibly not *in the dispenser* since it is liquid which would just drip out once opened).
** I don't think that it is filling at all... but dumps the water like the cycle is over. **
If it wasn't filling there would be nothing to "dump".
I'm afraid we're going to need more accurate details of *exactly* what is or is not occurring before anyone will be able to suggest a possible course of action.
If it is NOT filling, that's one thing. If it IS filling but draining (ie. actually pumping with force) that water out prematurely, than my comments in my previous post following "If it IS filling properly..." apply.
I shut off the power to the dishwasher, and located the fill valve and the float switch. I disconnected the wires to each device. I set my meter to Rx1, tested it to make sure a current was going through. I touched the leads on both the fill valve and the float switch and the needle did not move at all. Am I on the right track?
I took the parts to a department at work and had them to check them. He said the float switch seems fine. The fill valve was suspicious. I replaced the valve, and I am still having the same problem. The lower spray arm is not moving at when it is attempting to wash. I opened the door as it was on the wash cycle. I don't think that any water is coming through it at all.
** I don't think that any water is coming through it at all. **
Than someone will need to investigate why. The water valve might NOT be receiving power to open or it IS being powered but just not opening. I would think the latter case is unlikely if you just replaced the water valve with a brand new one.
Another possibility is the dishwasher is just not receiving any water. Is its water supply tap turned ON?
Is this dishwasher properly installed and has it been in that same location and working fine previous to this most recent complaint. It is not just newly installed into its current location?
