What This Guide Helps With
Bed not raising or lowering, slow hi-lo movement, intermittent function, or no response from height controls due to power, controls, or actuator-related issues.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Move the patient to another bed before troubleshooting.
- Engage brakes and ensure the bed is stable.
Expected: No risk to patient during troubleshooting
Why it matters: Unexpected bed movement or failure can create fall risk or injury.
Verify the Reported Issue
- Attempt to raise and lower the bed using all available controls:
- Side rail controls
- Footboard controls
- Pendant (if equipped)
- Observe:
- No movement
- Slow or uneven movement
- Clicking sounds or no sound
Expected: Consistent response from at least one control source
Why it matters: Helps determine if the issue is control-related or mechanical
Check Power Source and Bed Power Status
- Confirm the bed is plugged into a known working outlet.
- Check for:
- Power indicator lights
- Bed not running on battery only
- Test outlet with another device if needed.
Expected: Bed has stable AC power
Why it matters: Hi-lo actuators require sufficient power; battery-only operation may limit function
Inspect Power Cord and Connections
- Check the power cord for:
- Damage or cuts
- Loose connection at bed base
- Ensure the cord is fully seated.
Expected: Secure, undamaged power connection
Why it matters: Poor power delivery can cause slow or failed actuator movement
Check for Bed Lockout or Control Restrictions
- Verify that no lockout functions are active:
- Check caregiver control panel for disabled functions
- Ensure hi-lo function is enabled
Expected: Hi-lo function is not locked out
Why it matters: Lockouts can mimic actuator failure
Inspect for Physical Obstructions
- Look under the bed frame for:
- Debris or foreign objects
- Linens or equipment caught in the frame
- Damage to linkage or frame
Expected: Clear movement path
Why it matters: Obstructions can slow or stop actuator movement and strain the motor
Listen for Actuator Operation
- While pressing hi-lo controls, listen for:
- Motor running but no movement
- Clicking or grinding sounds
- No sound at all
Expected: Smooth motor sound with corresponding movement
Why it matters: Motor sound without movement → possible mechanical or actuator failure; No sound → possible electrical or control issue
Check Bed Weight Load
- Ensure the bed is not overloaded or unevenly loaded.
- Remove excess equipment if present.
Expected: Bed operates within normal load range
Why it matters: Excess weight can slow or stall actuator movement
Inspect Pendant and Control Cables
- If equipped, check pendant and control wiring for:
- Damage
- Loose connections
- Pinched cables
- Swap with a known working pendant if available.
Expected: Controls respond normally
Why it matters: Faulty controls can prevent actuator activation
Perform Power Reset
- Unplug the bed from AC power.
- Wait 30–60 seconds.
- Plug back in and retest hi-lo function.
Expected: System resets and may restore normal operation
Why it matters: Clears temporary control or communication faults
If the Problem Persists
If all external causes have been ruled out, the issue is likely internal, such as:
- Hi-lo actuator failure
- Control board or relay issue
- Internal wiring fault
Remove the bed from service. Label it Out of Service and send for repair or bench evaluation.
Knowing when to stop prevents unnecessary risk and protects patient safety.
Clinical Use Tip
Never troubleshoot bed movement functions with a patient in the bed. Always transfer the patient first to avoid fall or crush hazards.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Bed will not raise or lower; hi-lo function unresponsive."
Cause
What was observed during troubleshooting.
Example:
"Hi-lo actuator not responding despite verified power and controls."
Resolution
What action was taken.
Example:
"Removed bed from service and sent to shop for actuator evaluation and repair."
Helpful Details to Include (If Known)
- Outlet tested and verified
- Power indicator status
- Control panels tested (rails, footboard, pendant)
- Presence of actuator noise
- Any obstruction found
- Load condition of bed
- Final device status (in service or removed)
Final Thought
Hi-lo issues are often caused by simple external factors like power, controls, or obstructions. Systematic troubleshooting ensures safe operation while avoiding unnecessary part replacement. When the issue points to internal failure, prompt removal from service protects both patients and staff. Proper documentation supports efficient repair and future trend tracking.
That is successful troubleshooting.
