What This Guide Helps With

This guide helps troubleshoot Error: E327 Check Foot Pedal on the Medtronic Valleylab FT10 Electrosurgical Unit. This error indicates that the LigaSure foot pedal may be pressed, stuck, connected incorrectly, damaged, or causing an unintended activation input.

A foot pedal input issue on an ESU should be treated as a patient safety concern because unreliable activation control may affect how and when energy output is delivered.

Step-by-Step Troubleshooting

Ensure Patient Safety First

• Remove the Valleylab FT10 from patient use if the error appears during a case, activation is unreliable, or there is any concern for unintended energy activation.
• Stop use of the affected LigaSure foot pedal setup.
• Notify clinical staff that the ESU should not be used until the activation issue is corrected.
• Use another known-working ESU or approved backup activation setup if clinically needed.
• Do not continue using the ESU if the foot pedal input appears stuck, intermittent, or unreliable.

Verify the Reported Error and Behavior

• Power on the Valleylab FT10 and observe the display.
• Confirm the exact message is Error: E327 Check Foot Pedal.
• Check whether the error appears at startup, when the LigaSure foot pedal is connected, when the pedal is moved, or intermittently during use.
• Ask staff whether the issue occurred during setup, before activation, or during attempted LigaSure use.
• Confirm whether the pedal appeared physically pressed, stuck, wet, damaged, or obstructed.

Check for a Pressed or Stuck LigaSure Foot Pedal

• Inspect the LigaSure foot pedal before assuming an internal ESU failure.
• Make sure no one is pressing the pedal.
• Confirm the pedal returns freely when released.
• Look for fluid, debris, tape, drape material, cable tension, or objects pressing against the pedal.
• Clear any obstruction and recheck the ESU.

Disconnect the Foot Pedal and Recheck the Error

• Power the FT10 down.
• Disconnect the LigaSure foot pedal from the ESU.
• Inspect the connector before powering the unit back on.
• Power the FT10 on with the foot pedal disconnected.
• Check whether Error E327 clears when the suspect pedal is removed.

Inspect the Foot Pedal Cable and Connector

• Inspect the foot pedal cable from end to end.
• Look for crushed cable sections, cuts, exposed conductors, bent pins, broken connector housing, fluid contamination, loose strain relief, or damage from equipment rolling over the cable.
• Confirm the connector is clean, dry, undamaged, and fully seated when reconnected.
• Do not use the pedal if the cable or connector appears damaged.

Try a Known-Good LigaSure Foot Pedal

• Disconnect the suspect LigaSure foot pedal.
• Connect a known-good compatible LigaSure foot pedal.
• Power cycle the FT10 if needed.
• Check whether Error E327 returns.
• If the error clears with the known-good pedal, remove the failed foot pedal from service and document the accessory failure.

Check the ESU Foot Pedal Port and Connection Area

• Inspect the external LigaSure foot pedal port on the FT10.
• Look for bent or recessed pins, debris, fluid contamination, loose connector fit, or physical damage around the port.
• Do not use the unit if the connector area appears damaged or contaminated.
• If the port appears damaged, remove the ESU from service for evaluation.

Determine Whether the Issue Is Accessory-Related or Device-Related

• If the error clears when the foot pedal is disconnected, suspect the foot pedal, cable, connector, or pedal input path.
• If the error clears with a known-good foot pedal, suspect the original foot pedal.
• If the error remains with no foot pedal connected, suspect an ESU-side input issue.
• If the error returns with multiple known-good pedals, suspect the ESU connection area or internal input circuitry.

Check for Intermittent Cable or Movement-Related Symptoms

• Only perform this check in a safe, non-patient test condition.
• Gently move the foot pedal cable near the connector and strain relief.
• Observe whether the error appears, clears, or changes when the cable is moved.
• Do not activate energy into a patient during this testing.
• If movement causes the error to appear, remove the foot pedal from service.

Stop When Resolved

• If the issue is corrected by releasing the pedal, removing an obstruction, reseating the connector, cleaning or drying the external connection, or replacing the foot pedal, stop troubleshooting.
• Confirm Error E327 no longer appears.
• Confirm normal startup behavior.
• Confirm the foot pedal is not stuck or falsely activating.
• Return the FT10 to service only after the error is cleared and the setup is safe.

If the Problem Persists

If Error E327 remains after releasing the LigaSure foot pedal, disconnecting and reconnecting it, inspecting the cable and connector, checking the ESU port, and testing with a known-good compatible foot pedal, external causes have been ruled out.

Persistent E327 conditions may indicate an ESU-side issue involving the foot pedal input path, Controller PCBA, Steering Relay PCBA, Foot Pedal PCBA, or related internal circuitry.

The device should be removed from service, labeled Out of Service, and sent for repair or bench evaluation.

Do not continue using the ESU with an unresolved foot pedal input error.

Clinical Use Tip

Never troubleshoot a foot pedal activation error on an active patient. Move the patient or procedure to a known-working backup ESU setup before testing foot pedals, cables, connectors, or activation behavior. An unresolved foot pedal error should be treated as a possible unintended activation risk.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Valleylab FT10 displayed Error E327 Check Foot Pedal during setup/use. Staff reported the LigaSure foot pedal error and stated the system appeared to detect the pedal as pressed."

Cause

What was observed during troubleshooting.

Example:
"LigaSure foot pedal input issue confirmed. Pedal was checked for stuck activation, obstruction, cable damage, connector seating, and contamination. Known-good foot pedal was used to isolate the fault."

Resolution

What action was taken.

Example:
"Released and inspected LigaSure foot pedal, checked cable and connector, reseated connection, and tested with known-good compatible foot pedal. Failed foot pedal was removed from service after error cleared with replacement pedal. ESU passed functional check and was returned to service."

Helpful Details to Include (If Known)

• Alarm behavior
• Accessories swapped
• Power behavior
• Environmental factors
• Indicator lights
• Final device status

Final Thought

Error E327 Check Foot Pedal should be handled as a possible unintended LigaSure activation input. Start with patient safety, verify the exact error, inspect the foot pedal and cable first, then isolate the issue with a known-good compatible pedal. If the error remains after external causes are ruled out, remove the ESU from service and escalate it for repair evaluation. Clear documentation protects the patient, the clinical user, and the technician.

That is successful troubleshooting.
