Abstract
Disclosed are systems and methods for detecting a malfunction in an automated analyzer. The systems and methods may include receiving a signal from a sensor (), such as a Hall effect sensor located proximate a coil () of a solenoid valve (). The signal from the sensor may be correlated to a magnetic flux or change in the magnetic flux generated as a plunger () of the solenoid valve is drawn into the coil when the coil is energized. Deviations in the signal from a reference may indicated a malfunction of the solenoid valve. Upon detecting a malfunction, a pre-failure status may be determined.
