Chapter 8: Troubleshooting

Step 2: Visual Inspection

After confirming that there are no warning or error messages indicating a specific problem, proceed to a visual
inspection of the Analyzer to identify any obvious physical problems or symptoms. Begin with an external visual
inspection, and proceed to an internal visual inspection. If possible, perform the inspection with the Analyzer in
analysis mode so you can verify that relevant modules are performing as usual (described below).

External Inspection

• Confirm that there are no leaks present at the sample inlet or the waste connections.
• Confirm that all cables are securely attached to the Analyzer.
• If you are sampling from vials, confirm that the needle in the iOS System is not obstructed.

Internal Inspection

Open the Analyzer front panel and do the following:
• Check for leaks throughout the Analyzer; there should not be moisture on the inside floor of the
Analyzer case.
• Confirm that the sample pump is turning.
• Check to make sure there are no leaks from tubing in the DI water system.
• Confirm that the DI water cartridge is full. If necessary, add water up to the Full line.
• If maintenance work has recently been performed on the Analyzer, confirm that electronics cables,
such as the connector between the analog and ID boards, are securely attached.
• Make sure there are no air bubbles present in any of the DI loop tubing.
• Make sure tubing is not bent or obstructed.
• Make sure the UV lamp is working. During analysis, the window on the UV reactor will illuminate when
the lamp is functioning properly.
Note that if tubing has become bent, kinked, or otherwise damaged, a tubing replacement kit is available from
GE Analytical Instruments Technical Support.

Step 3: Review Solutions for Basic Problems

If a visual inspection of the Analyzer does not help you identify the source of the problem you are experiencing,
consult the specific problems discussed in this section.
