• [441] Sampler door opened.
Possible Causes:
• Autosampler compartment door accidentally opened
• Door not closing properly
• Door sensor malfunction
• Door magnet missing
Actions:
• The autosampler door must be closed to operate the AS. Close the
door and restart the schedule, if necessary.
• If the door appears closed, but the message still occurs, check for
an obstruction that is preventing the door from closing
completely.
• Make sure the magnet on the inside lower front edge of the door
is present. Also make sure the magnet on the lower edge of the
autosampler compartment is present. If a magnet is missing,
contact Dionex.
• [443] Leak detected in tray/syringe area.
Possible Causes:
• Excess liquid in the waste container is preventing liquid from
siphoning through the waste tubing
• Blocked or crimped waste tubing
• Leaking inject port
• Miscalibrated leak sensor
Actions:
• Empty the waste container.
• Make sure the waste tubing is not crimped and that it is not
pushed against the bottom of the waste container.
• If the inject port is leaking, see Section 4.2.3.
• If the tray is dry, but the error is still appearing, recalibrate the
sensor (see Section 5.11
).
