Any time a cycle is aborted the Tuttnauer autoclave will give an error message. These messages describe the problem the unit has encountered. The following is a list of those Error Messages with descriptions of what they mean and, and indications of where the problem may be

Tuttnauer Error Codes For "E" Series Autoclaves

Error Message What The Error Message Means What Is Causing The Error Message

ADD WATER

This message is displayed and the ADD WATER indicator lights to show insufficient water in the Water Reservoir
  • If this message is displayed after the START Key has been pressed then the system is not allowed to proceed
  • After water is added to the Reservoir, the START Key must be depressed again in order for the selected cycle to begin
If the reservoir has a sufficient amount of water in the reservoir, and the add water message is still being given, then the Reservoir Water Level Switch must be replaced

LOW WATER

This message will be displayed if during a normal Heat Up stage the system determines that there is insufficient water in the Chamber to complete the cycle. This determination is made by the combined input of two sensors, the Water Electrode and the Safety Thermostat
  • Also if a power failure occurs during the Heat or Sterilization stage after the power returns the system will check the Water Electrode to see if there is sufficient water in the Chamber in order to resume the cycle.
  • If not the cycle will be aborted, the message LOW WATER will be displayed, and the Cycle Fail indicator will light
Possible causes for this message are:
  1. Insufficient water entered the Chamber at the beginning of the cycle. Check for proper leveling, a dirty or shorted Water Sensing Electrode, a clogged Water Pump, a partially clogged line or that the Air Outlet V alve is stuck closed
  2. A leaky Solenoid Valve, Safety Valve, Air Jet, Door Gasket, Door Bellows or a pipe fitting is allowing water or steam to escape at a higher than normal rate
  3. A power down has occurred and on power up if the water Electrode tip is dry the Low Water message will be displayed

LOW HEAT

This message is displayed, the Cycle Fail indicator lights and the cycle is aborted if the autoclave has not reached sterilization temperature after heating for 50 minutes in either Wrapped or Unwrapped programs (80 minutes in the Liquid program)
  • Low Heat refers to the temperature in the Chamber before sterilization has begun
Possible causes for this message are:
  1. No power to the Heating Elements
  2. Bad Heating Elements
  3. Very low line voltage delaying heat up
  4. Safety Thermostat is opening prematurely, turning off the Heating Elements (This only applies to units with Microprocessors dated earlier than T93N5 or T93N6)
  5. A clogged Air Jet
  6. An Air Outlet Valve is stuck closed

LOW TEMP

This message is displayed, the Cycle Fail indicator lights and the cycle is aborted if the temperature drops 2.5°C (4.5°F) below the required sterilization temperature Possible causes for this message are:
  1. Insufficient water in the Chamber (see Low Water message)
  2. The sterilization phase of the cycle has been set for too long a period of time, allowing the Chamber water to boil away, and the Chamber to run dry
  3. The Safety Thermostat is opening prematurely, turning off the Heating Elements (this only applies to units with Microprocessors dated earlier than T93N5 or T93N6)
  4. A bad Temperature Sensor

LOW PRES

This message is displayed, the Cycle Fail indicator lights, and the cycle is aborted if the pressure drops 4 PSI (0.27 BAR) below the required sterilization pressure Possible causes for this message are:
  1. Insufficient water in the Chamber ( see Low Water message)
  2. The Heating Elements not cycling on and off properly
  3. Problem with the Solid State Relay
  4. Problem with the control circuit
  5. Bad Heating Elements -- not producing enough wattage
  6. The Safety Thermostat is opening prematurely, turning off the Heating Elements -- this only applies to units with Microprocessors dated earlier than T93N5 or T93N6
  7. A bad Pressure Transducer

HI TEMP

This message is displayed, the Cycle Fail indicator lights and the cycle is aborted if the temperature rises 5°C (9°F) above the required sterilization temperature during the Sterilization phase of the cycle
  • This message will also be displayed if the Temperature Sensor is damaged. In this case the message will appear just before the Heat phase starts
Possible causes for this message are:
  1. The Heating Elements are remaining on instead of cycling on and off
  2. Check for a shorted Solid State Relay, shorted Heating Element or other short circuit
  3. This message can ALSO indicate a bad Temperature Sensor - the message will display any time during the Heat Up phase

HI PRES

This message is displayed, the Cycle Fail indicator lights, and the cycle is aborted if the pressure rises 10 PSI (0.6 BAR) above the required sterilization pressure Possible causes for this message are:
  1. The Heating Elements are remaining on instead of cycling on and off. Check for a shorted Solid State Relay, shorted Heating Element or other short circuit
  2. The Sterilization temperature has been set above 274°F

MAN STOP

This message will be displayed and the Cycle Fail indicator will light after the STOP Key is depressed for longer than 1 second Informational Only

RENEW WATER

This message is displayed only as information to the operator, that the Water Reservoir should be drained and refilled with clean distilled water. This message will only appear on units with Microprocessors date coded earlier than, and including, T93N5 Drain Reservoir & Refill With Clean Distilled Water

POWER DN

This message is displayed once the power is restored, after a power failure occurs during the running of a cycle.
  • The POWER DN message will be displayed for several seconds, and if present, the Printer will print POWER DN on the print out
Once power has been restored the autoclave will make an attempt to resume the current cycle from the point at which it was interrupted
  • If a power failure occurs during the Heat Up phase, then heating will resume (provided there is enough water in the Chamber - If not, the cycle will be aborted)
  • Exhaust and Dry phases will automatically resume operation once power is restored
  • If the power down occurred during the Sterilization portion of the cycle, then when power is restored, the autoclave will check if the temperature in the Chamber has fallen more than 2.5°C (4.5°f;F)
  • If not then the Sterilization Cycle will resume automatically. If however, when the power returns, the system determines that the temperature has fallen more than 2.5°C (4.5°f;F), the Sterilization Cycle will abort and the Exhaust Cycle will start
  • If a power failure occurs during the Liquids program, the system will not allow a fast exhaust (as the exhaust valve is normally closed), nor will it fast exhaust when power comes back on

DOOR UNLOCK

This message will be displayed and the DOOR CLOSED indicator will remain unlit if the door is improperly closed when the START Key is depressed Once the door is properly closed, the DOOR CLOSED indicator will light and the START Key should be depressed to start the desired cycle
  • If the door accidentally opens during any stage of the cycle, the same message and indicator will appear, and the system will abort, the Cycle Fail indicator will light and the DOOR UNLOCK message will be displayed.

WATER INLET

This message will be displayed as information to the operator while water is entering the Chamber, during the Automatic Water Filling process Informational Only

CYC FINISHED

This message is displayed at the end of a successfully completed cycle Informational Only
