Error Information
General Error Messages

Leak Sensor Short

Error ID: 0082
The leak sensor in the module has failed (short 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 increases above the upper limit,
the error message is generated.

Compensation Sensor Open

Error ID: 0081
The ambient-compensation sensor (NTC) on the power switch board in the
module has failed (open circuit).
The resistance across the temperature compensation sensor (NTC) on the
power switch board is dependent on ambient temperature. The change in
resistance is used by the leak circuit to compensate for ambient temperature
changes. If the resistance across the sensor increases above the upper limit,
the error message is generated.

Defective leak sensor.
Leak sensor incorrectly routed, being
pinched by a metal component.
Power switch assembly defective
Loose connection between the power
switch board and the main board
Defective power switch assembly
Suggested actions
Exchange the leak sensor.
• Make sure the leak sensor is installed
correctly.
• Correct the routing of the cable.
• If cable defective, exchange the leak
sensor.
Exchange the power switch assembly.
Suggested actions
Check the ribbon cable between the power
switch board and the main board.
Exchange the power switch assembly.
