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.
