TROUBLESHOOTING
Instrument troubleshooting always begins with use of the Effective Troubleshooting model. The model
includes information gathering techniques along with knowledge about the major systems of the analyzer
(FORT) to identify the root cause of the failure.
Effective troubleshooting and problem resolution requires four logical STEPs:
• STOP - Identify the Problem
• THINK - Gather Information/Data
- Look for Comparison
• The problem IS vs. the problem IS NOT
• Identify Normal operation/performance vs. Failure
- Gather Clues
• Use Diagnostic Testing/Measurements
• Identify Symptoms
- Categorize Failure
• Area of Failure: Operator, Reagent, Environment, Analyzer
• Instrument System (FORT - Fluidics, Optics, Robotics, Temperature)
• EVALUATE - Identify potential Causes
- Verify problem
- Check Causes against data
• PROCEED - Resolution/Corrective action
- Isolate and correct Root cause of failure - Perform Repair
- Verify Problem Resolution
Information Gathering
Gather pertinent system information. This includes asking questions surrounding What, Where, When, and
How Often or How Many. Questions such as:
• When was the recommended preventative maintenance last performed?
• What Reagent kit, Calibrator, Control, Bulk Solutions, lot numbers are in use and what are the
expiration dates?
• What tests aren’t being affected?
• When did the problem first occur (Date/Time)?
• When was the last time the problem was not occurring?
• What troubleshooting steps have been taken?
• Is the problem observed or is an instrument error displayed/printed?
