// ENGINEER'S LOG

The GE dishwasher is stopping mid-cycle without an error code, and the soap dispenser often remains closed. While a prior attempt was made to clean the pressure sensor, the provided context indicates that severe clogs can render cleaning ineffective, necessitating replacement. Multiple instances in the search context confirm that replacing the pressure sensor directly resolved this exact symptom, even when initial cleaning attempts failed or were insufficient. The appliance technician's initial assessment may not have fully identified this intermittent or advanced failure of the sensor. // SAFETY NOTE: Ensure unit is disconnected from all power sources before inspection. Forensic analysis is for component identification only.
