General Error Messages

Leak

Error ID: 0064
A leak was detected in the module.
The signals from the two temperature sensors (leak sensor and board-mounted
temperature-compensation sensor) are used by the leak algorithm to determine
whether a leak is present. When a leak occurs, the leak sensor is cooled by the
solvent. This changes the resistance of the leak sensor which is sensed by the
leak-sensor circuit on the main board.

Leak Sensor Open

Error ID: 0083
The leak sensor in the module has failed (open circuit).
The current through the leak sensor is dependent on temperature. A leak is
detected when solvent cools the leak sensor, causing the leak-sensor current to
change within defined limits. If the current falls outside the lower limit, the error
message is generated.
