Lumenis LightSheer Machines:

• Error Code P3:

  • Description: Laser Diode Too Hot Over Temperature.
  • Cause: Laser diodes are weakening and overheating, possibly needing replacement.

• Error Code E3:

  • Description: Problem with the central processing unit (CPU) on the embedded computer board.
  • Cause: CPU corruption, may require replacement computer boards.

• Error Code E6:

  • Description: Over-Current.
  • Cause: Problem with laser diodes inside the LightSheer handpiece, often due to burning after prolonged use. Handpiece refurbishment and diode replacement may be necessary.

• Error Codes E12 & E18:

  • Description: Handpiece Diode Failure.
  • Cause: Weakening of diodes inside the handpiece due to prolonged use. Handpiece refurbishment and diode replacement may be required.

• Error Code E14:

  • Description: Pulse Width Error.
  • Cause: Likely a problem with the PWA Main board or CPU board.

• Error Code E15:

  • Description: Calibration out of range.
  • Cause: Operating temperature outside the calibrated range, requiring recalibration.

• Error Code E17:

  • Description: Calibration Inconsistent.
  • Cause: Check handpiece diode condition and diode lens; perform energy meter calibration. If diodes are okay, it could be a computer board issue.

• Error Code E18:

  • Description: Current Tolerance.
  • Cause: May resolve by restarting the system; if seen with Error E12, handpiece diode replacement may be needed.

• Error Codes E26 or E27:

  • Description: Power Supply.
  • Cause: E26 may resolve by restarting; E27 usually requires power supply replacement.

• Error Code E043 HS (LightSheer Duet):

  • Description: Handpiece trigger error 4.
  • Cause: Trigger pressed and trigger released sensors opened simultaneously. Reconnect handpiece and reboot; if error repeats, replace handpiece.

• Errors E81, E83 (LightSheer Duet):

  • Description: Diode over current.
  • Cause: Diodes inside the handpiece weakening after prolonged use. Refurbishment and diode replacement may be necessary.

• Errors E82, E84 (LightSheer Duet):

  • Description: Laser diode current too low.
  • Cause: Diodes inside the handpiece weakening after prolonged use. Refurbishment and diode replacement may be necessary.

• Error E135HS (LightSheer Duet):

  • Description: 135 handpiece backplane over temp.

Stuck in "Cooling Mode":

• Description: The machine does not display an error code and does not enter ready mode.
• Cause: Diodes in the handpiece overheated, or there's an issue with the cooling mechanism or temperature sensor inside the handpiece.
