What This Guide Helps With
Identifies and resolves cycle aborts caused by water temperature deviations or heating issues, focusing on external and easily verifiable causes.
Step-by-Step Troubleshooting
Ensure Patient and Staff Safety
- Verify the washer is empty of instruments and staff is clear of spray arms.
- Why: Prevents burns or accidental exposure during testing.
Check Power Supply and Indicators
- Confirm unit is plugged into a live outlet and main power switch is ON.
- Inspect display for error codes related to heating or temperature.
- Expected: Display powers on and no mains voltage warnings.
Verify Water Supply and Temperature Settings
- Ensure hot and cold water supply valves are fully open.
- Confirm incoming water temperature is within manufacturer-specified range (~20–50 °C).
- Expected: Steady inlet water flow without leaks.
Inspect Detergent and Rinse Additive Systems
- Check that dosing pumps and lines are clear and operational.
- Why: Some cycles abort if dosing solutions affect sensor readings.
- Expected: Proper flow and no airlocks in supply lines.
Check Temperature Sensors and Probes
- Ensure sensors are properly seated in their channels; inspect for visible damage.
- Expected: No loose probes; connectors seated securely.
Run a Test Cycle
- Initiate a short or test cycle without instruments.
- Observe temperature ramp-up and heating progress.
- Expected: Unit reaches set temperatures without abort.
Swap or Reset External Components if Possible
- If a sensor or inlet valve has a redundant counterpart, swap temporarily to test.
- Expected: Cycle completes if external component was causing the issue.
If the Problem Persists
External causes likely ruled out; internal heating element or controller failure suspected.
Action: Remove washer from service, label Out of Service, and send for bench evaluation.
Knowing when to stop avoids patient risk and equipment damage.
Clinical Use Tip
Do not run cycles with instruments during troubleshooting.
Always move critical instruments to another washer-disinfector until the HS Series is cleared for use.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Washer aborted cycles with “water temperature error” displayed."
Cause
What was observed during troubleshooting.
Example:
"Inlet water supply verified; temperature sensors seated; issue persisted."
Resolution
What action was taken.
Example:
"Device removed from service and sent for manufacturer repair."
Helpful Details to Include
- Outlet tested and verified
- Water supply valves fully open
- Temperature sensors checked
- Error code captured
- Test cycle attempted
- Device status: Out of Service
Final Thought
Patient safety and logical troubleshooting prevent unnecessary exposure to faulty equipment. Documenting steps ensures accountability and supports proper escalation when internal faults are suspected.
That is successful troubleshooting.
