What This Guide Helps With
This guide addresses situations where the Hillrom Centrella Smart+ bed’s drive motor fails to operate correctly. Symptoms may include:
- Bed unable to move forward, backward, or adjust height automatically
- Motor makes unusual noises (grinding, buzzing) without movement
- Intermittent or complete failure of motor function
- Alarms related to bed mobility
Focus is on simple external checks before assuming internal motor failure, ensuring safe patient care, and proper documentation.
Step-by-Step Troubleshooting
Verify Power Supply
- Check that the bed is plugged into a functional outlet.
- Ensure that the bed’s main power switch is ON.
- Confirm battery charge if applicable.
Why: Motors will not operate without proper voltage; power issues are a common cause of drive failure.
Inspect Cables and Connectors
- Examine power and motor control cables for damage, kinks, or loose connections.
- Ensure connectors are fully seated at both the motor and control interface.
Why: Loose or damaged cables can prevent motor operation or cause intermittent function.
Check the Bed Control Interface
- Attempt to move the bed using the control panel and/or pendant.
- Verify that no error codes or motor lockouts are displayed.
Why: If controls are not sending commands properly, the motor will not operate.
Test Bed Movement Without Load
- Move the bed without a patient to see if the motor functions normally.
- Observe for unusual sounds, sluggish movement, or failure to start.
Why: This isolates mechanical binding or excessive load from motor malfunction.
Inspect for Mechanical Obstructions
- Check wheels, tracks, or drive components for debris, jams, or physical damage.
- Ensure the brakes are fully released during the test.
Why: Mechanical interference can prevent the motor from moving the bed.
Reset the Bed System
- Power down the bed, wait 30–60 seconds, then power it back on.
- Test motor function again.
Why: Temporary electronic faults may be cleared with a system reset.
If the Problem Persists
If the bed still does not move, unusual sounds persist, or error codes remain after all external checks:
- Remove the bed from service
- Label it Out of Service
- Send it for repair or bench evaluation by qualified personnel
Note: Stopping here ensures safe troubleshooting and prevents further damage.
Clinical Use Tip
Do not attempt to move a patient on a bed with a malfunctioning drive motor.
Transfer the patient to another bed or stretcher before performing motor troubleshooting.
Always ensure patient safety is the first priority during any mechanical checks.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
“Bed drive motor will not move the bed forward or backward; motor produces a humming noise.”
Cause
What was observed during troubleshooting.
Example:
“Power verified, cables intact, control panel functional, no mechanical obstructions; motor failed to engage during testing.”
Resolution
What action was taken.
Example:
“Bed removed from service, labeled Out of Service, sent for manufacturer repair.”
Helpful Details to Include
- Outlet tested and functional
- Battery level if applicable
- Control panel response and error codes
- Motor sounds or unusual vibrations
- Mechanical components inspected
Final Thought
Thoroughly documenting external checks, isolating the issue logically, and escalating appropriately preserves patient safety, reduces risk of further equipment damage, and ensures accountability. Avoid guessing or forcing operation; proper escalation is key.
That is successful troubleshooting.
