M9 & M11 Troubleshooting - Error Codes - Newer Autoclaves

If an electronic malfunction is detected during a cycle, a numeric error code will appear on the display panel.

Each number in the error code provides information about the problem that occurred.

• The First Number Tells You Where The Problem Is Located (The Component)
  (example: The number 3 is the Door Switch)



 
• The Second Number Indicates What Problem Or Symptom Was Detected (Problem)
  (example: The number 8 = Open)



 
• The Third Number Tells You When The Problem Was Detected (Mode)
  Example: The Number 2 = Fill Mode)



 
• The table below cross-references the numeric error code with the Component, Problem, and Mode.
   

  First Digit (Component)	Second Digit (Problem)	Third Digit (Mode)
  0= General System	0 (not used)	0= Power-Up Mode
  1= Stop Button	1= Power Loss	1= Select Cycle
  2= Water Level Sensor	2= Closed	2= Fill Mode
  3= Door Switch	3= Low	3= Heat-Up Mode
  4 (not used)	4= High	4= Sterilizing Mode
  5= Temperature Sensor	5not used)	5= Vent
  6= Pressure Sensor	6= Hardware	6= "Door To Open"
  7 (not used)	7= Over Limit	7= Dry
  8 (not used)	8=Open	8 (not used)
  9= High Limit Thermostat	9 (not used)	9 (not used)
