What This Guide Helps With
Troubleshooting Error 202 Head Right Load Cell, indicating a head-right load-cell range fault that may affect scale accuracy, Bed Exit monitoring, and iBED Awareness reliability.
While this error is active, the bed should not be relied upon for accurate patient weighing or monitoring functions that depend on load-cell information.
Step-by-Step Troubleshooting
1. Ensure Patient Safety First
- Remove the Stryker S3 bed from patient use if Error 202 Call Service is displayed or if the Scale, Bed Exit, or iBED Awareness functions are needed for safe patient care.
- If the bed is occupied, coordinate with clinical staff to safely transfer the patient to a known-working bed before troubleshooting.
- Do not rely on weight, Bed Exit, or iBED Awareness status information from the affected bed until the fault is corrected and verified.
Expected outcome: The patient is supported by equipment with reliable monitoring and safety functions.
Why it matters: A head-right load-cell fault may cause inaccurate weight sensing or unreliable Bed Exit and iBED Awareness operation.
2. Verify the Reported Error and Associated Behavior
- With the bed removed from clinical use, power the bed on as appropriate and confirm that the display reports Error 202 Call Service.
- Document whether the error appears immediately at startup, after bed movement, after weight is applied to the patient surface, or intermittently.
- Check for associated symptoms such as unstable or inaccurate scale operation, Bed Exit concerns, unavailable iBED Awareness status, or recurrence after power cycling.
Expected outcome: Error 202 is reproduced or clearly confirmed, with any related scale or awareness-system behavior documented.
Why it matters: Confirming the displayed condition helps distinguish an active head-right load-cell fault from a temporary loading or setup concern.
3. Check Bed Setup and External Interference
- Place the bed on a level surface with the wheels positioned normally.
- Check that the bed is not contacting a wall, equipment, cords, furniture, or other objects.
- Inspect beneath and around the bed for trapped items, linens, straps, or accessories pulling against the frame.
- Look for visible twisting, bending, or abnormal loading of the head-right corner.
- Remove any external interference and retest the bed.
Expected outcome: The bed is free of external contact or binding that could falsely load the head-right sensing point.
Why it matters: Mechanical binding or uneven external loading may drive a load-cell reading outside its expected range.
4. Inspect the Head-Right Load-Cell Area
- Visually inspect the head-right load-cell location and surrounding frame area for impact damage, deformation, looseness, misalignment, contamination, or debris.
- Inspect visible wiring for pinching, pulling, cuts, abrasion, or routing that interferes with frame movement.
- Check accessible connectors for obvious looseness or damage.
- Do not perform internal disassembly during initial troubleshooting of the unresolved fault.
Expected outcome: No obvious mechanical damage, binding, cable fault, or frame interference is present, or a correctable external issue is identified.
Why it matters: Physical damage or wiring concerns in the head-right sensing area may explain the out-of-range load-cell condition.
5. Check Accessories and External Loading Conditions
- Remove unnecessary removable accessories, stored items, or attached equipment that could create uneven loading during testing.
- Confirm the patient surface and external accessories are installed normally and are not placing abnormal force on the head-right frame area.
- After correcting any setup issue, power cycle the bed and determine whether Error 202 returns.
Expected outcome: The bed remains free of abnormal external loading, and the error either clears or persists under controlled evaluation conditions.
6. Review Load-Cell Diagnostic Information
- With the bed removed from service and safe for evaluation, access the applicable load-cell diagnostic information according to approved service procedures.
- Document whether the diagnostic information identifies the head-right sensing path, such as Load Cell Error with HR indicated.
- Record the displayed diagnostic result in the work order.
Expected outcome: Diagnostic information supports whether the head-right load-cell circuit remains the suspected source of the error.
Why it matters: A repeated head-right indication helps isolate the complaint from a general scale concern.
7. Determine Whether an External Cause Was Corrected
- If removing interference, correcting abnormal external loading, or securing an accessible connection clears the error, continue with full functional verification.
- If visible frame damage, harness damage, or persistent head-right diagnostic indications remain, stop field troubleshooting and escalate for repair.
- Do not return the bed to patient use merely because the error temporarily disappears.
Expected outcome: The condition is identified as either corrected externally or requiring repair and bench evaluation.
8. Verify Operation After Correction or Repair
- Confirm that Error 202 Call Service no longer displays during normal power-up and evaluation.
- Verify scale operation and weight accuracy according to facility and manufacturer procedures.
- Verify Bed Exit setup and alarm operation.
- Verify iBED Awareness operation.
- Confirm the bed is free of recurring load-cell errors before return to service.
Expected outcome: The error is cleared and all affected systems pass functional verification.
9. Stop When Resolved
- If the error clears and the bed passes scale, Bed Exit, and iBED Awareness functional testing, document the work performed and return the bed to service.
- If the error remains or affected functions cannot be verified, keep the bed out of service and escalate for repair.
If the Problem Persists
If Error 202 Call Service remains present after external interference, setup conditions, visible wiring concerns, accessible connections, and abnormal loading have been evaluated, external causes have been ruled out as far as practical during initial troubleshooting.
- Remove the device from service.
- Label the device Out of Service.
- Send the bed for repair or further bench evaluation.
- Require recalibration and verification of Scale, Bed Exit, and iBED Awareness operation after repair before return to clinical use.
A bed with an unresolved load-cell fault should not be relied upon for patient weighing, Bed Exit monitoring, or iBED Awareness functions.
Clinical Use Tip
Never troubleshoot a load-cell, scale, Bed Exit, or iBED Awareness fault on an active patient. Move the patient to a backup device first, and do not rely on the affected bed's monitoring or weighing functions until the error is corrected and verified.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Stryker S3 hospital bed displayed Error 202 Call Service - Head Right Load Cell. Scale, Bed Exit, and iBED Awareness functions were considered unreliable while the error was active."
Cause
What was observed during troubleshooting.
Example:
"Confirmed Error 202 Call Service. No external frame interference or abnormal loading was found. Load-cell diagnostic information identified the HR sensing path, indicating a likely head-right load-cell or related circuit fault."
Resolution
What action was taken.
Example:
"Removed bed from patient use, labeled Out of Service, and referred for bench repair. Required scale recalibration and verification of Bed Exit and iBED Awareness operation before return to service."

- Environmental factors
- Indicator lights
- Final device status
Final Thought
Error 202 is not only a scale concern; it may also affect Bed Exit and iBED Awareness functions used for patient safety. Safe troubleshooting begins with removing the bed from patient use, checking external loading and visible damage, documenting diagnostic findings, and escalating for repair when the condition persists. Clear CCR documentation supports safe return-to-service decisions.
That is successful troubleshooting.
