Question about GE 24 in. GSD4020Z Built-in Dishwasher
I replaced the pump and the piston nut assembly. All hoses clear. No air gap, no disposer. What's left to check/replace? I am at a loss.
When you replaced the pump I am assuming you replaced the whole assembly that pumps water for the wash and drain. See item 310 in this diagram.
If the dishwasher goes through the wash cycle then it was unlikely the thing that was faulty. The pump is shared by both the wash and drain cycle. It is likely the impeller (item 429) is not getting the pulse to change direction so that it draws water from the drain sump to the drain hose rather then to the wash arms as it does in wash cycle. The solenoid connection might be faulty or the controller output is not there.

Check the following to address this issue--
1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.
If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.
Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.
2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.
Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.
4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.
Replace the motor if defective.
Replace if defective (note: uncommon problem).

SOURCE: DW will not drain
If the dishwasher is not completely draining, your dishes probably aren't as clean as they could be either.
Most dishwashers have a filter screen to keep solid food from getting into the pump. This could be stopped up. Also look for kinks in the drain hose.
