Brand: GE Dishwasher
Model Number: gdt550pyr3fs
Main Symptom: H2O error code
What happens & when: cycles water from inlet, and stalls afterwards. The following parts have been replaced: inlet valve, circulation pump, drain pump, and pressure sensor. Keep trying to start the dishwasher and finally is came on and cycled all the way until wash cycle. During the wash the H2O error code came back and it stopped. Any help keeping it running since everything except the sensor that measures the cloudiness of the water has been replaced. Machine short cycles then adds water but over runs with water.

Error Code (if any): H2O
Parts or tests already tried: all above parts are new except pressure sensors purchased 2025

This sounds like an issue with water supply. If the pressure sensor and valve are new then this would most likely be a control board that is faulty.

Ok thanks. I will give it one last try given everything has almost been replaced. Practically a new dishwasher. Thanks for the quick response
