1. A diagnostic system for a closed fluid system composed of a first fluid subsystem and a second fluid subsystem connected using a valve, the diagnostic system comprising:
a first sensor disposed in the first fluid subsystem and configured to measure a first fluid level of the first fluid subsystem, and output first time-ordered fluid level measurements corresponding thereto;
a second sensor disposed in the second fluid subsystem and configured to measure a second fluid level of the second fluid subsystem, and output second time-ordered fluid level measurements corresponding thereto; and
a computer coupled to the first sensor and the second sensor, and configured to:
receive the first time-ordered fluid level measurements and the second time-ordered fluid level measurements from respectively the first sensor and the second sensor;
perform a comparison of the first fluid level with the second fluid level from the first time-ordered fluid level measurements and the second time-ordered fluid level measurements;
produce a notification indicating a predicted malfunction of the valve when, based on the comparison, the first time-ordered fluid level measurements and the second time-ordered fluid level measurements have at least a threshold divergence; and
output the notification for display to a user,
wherein the computer configured to perform the comparison includes being configured to determine a correlation and an absolute difference between the first time-ordered fluid level measurements and the second time-ordered fluid level measurements that define a divergence thereof, and
wherein the computer configured to produce the notification includes being configured to produce the notification when the divergence is at least the threshold divergence.
