Brand:GE Model Number:GDP655SYN0FS Main Symptom: STOPS MID-CYCLE What happens & when:the dishwasher starts normally but stops mid cycle and does not rinse, leaving a residue on the dishes
Error Code (if any):none
Parts or tests already tried: I have entered the diagnostic mode and manually activated the water inlet, agitation, and drain, all of which worked fine from the diagnostic. Initially, it seemed as if there was not enough water, so I replaced the water inlet valve. Initially, that seemed to correct the problem, but after one or two cycles, it began doing the same thing. I tried several cycle settings and had the same result on each one. The cycle starts normally and then stops about midcycle after draining to prepare for rinse. If I try to restart at that point, the pump runs continuously even when the door is opened.

Thanks for the detailed information. You’ve already done some good troubleshooting on your GE GDP655SYN0FS dishwasher, and the fact that the fill valve, circulation pump, and drain pump all work in diagnostic mode is a helpful clue.
What really stands out is that the dishwasher stops after draining, just before the rinse portion of the cycle, and the drain pump runs continuously when you try restarting it.
That makes me suspicious of the dishwasher’s flood protection system, water-level sensing circuit, or main control board, rather than the water inlet valve itself.
Here’s how I’d narrow it down before replacing anything else.
1. Check for water in the dishwasher’s base
Some GE dishwashers have a leak-detection system that can activate the drain pump if water collects underneath the tub.
Turn off power to the dishwasher at the breaker.
Remove the lower access panel.
Look underneath the dishwasher for standing water, moisture, or signs of a leak.
If your particular configuration has a base flood sensor, inspect its wiring and surrounding area.
What the results mean:
If you find water underneath, investigate the leak before replacing any electrical components.
If everything is dry, move on to the next test.
Not every version uses the same flood-detection arrangement, so we don’t want to assume yours has a separate float sensor.
2. Inspect the pressure sensor and its opening
Your dishwasher uses water-level sensing to help the control determine whether the tub has filled and drained properly.
A clogged pressure sensor or sensing opening can cause the control to receive an incorrect water-level reading.
Disconnect power.
Remove the lower dish rack and filter assembly.
Inspect the sump area for food debris, grease, or buildup.
Locate the pressure sensor on the sump assembly, typically accessed from underneath.
Inspect its sensing opening for debris and check the electrical connector for moisture or corrosion.
Clean any accessible buildup carefully. Avoid forcing tools into the sensor or blowing compressed air into it, since that can damage the sensing mechanism.
If the control incorrectly believes water is still present, it may continue draining instead of advancing into the rinse portion.
3. Check the door latch and wiring
An intermittent door-latch signal can also interrupt a cycle.
With the power disconnected, inspect the latch and its wiring connections.
However, because you mentioned that the drain pump continues running even when the door is opened, I would prioritize the water-level and flood-protection checks over replacing the door latch.
4. Check the main control board
If the pressure sensor and wiring check out, the main control board becomes a stronger possibility.
The control may be failing to recognize that the drain portion has completed or may be receiving an incorrect water-level signal.
Since all three components operate during diagnostic testing, we know they’re capable of running. What we haven’t confirmed is whether the control is receiving the correct feedback during an actual wash cycle.
I wouldn’t replace the board until we’ve ruled out the pressure sensor and its wiring.
5. One important test
The next time the dishwasher stops, don’t immediately reset it.
Open the door and check whether there’s standing water inside the tub.
Then note whether the drain pump is still running and whether the control panel responds normally.
One question that will help us narrow this down:
When the dishwasher stops halfway through the cycle, does the drain pump continue running by itself, even with the door open, or does it only start running continuously after you press Start to restart the cycle?
That distinction will help determine whether we’re dealing with a water-level sensing problem, a flood-protection response, or a control issue.
