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.
Probable cause Suggested actions
1 Condensation.
Use a higher temperature setpoint.
2 Loose column fittings.
Ensure all fittings are tight.
3 Broken capillary.
Exchange defective capillaries.
4 Leaking column-switching valve seal.
Exchange the valve seal.
