Low Heat Message is displayed and sterilization does not start if the
autoclave has not reached sterilization temperature after
heating for 50 minutes while in the Wrapped or Unwrapped
programs (80 minutes in the Glassware program).
Possible causes:
♦ A clogged Air Jet (see cleaning the Air Jet sec 9.4).
♦ No power to the heating elements.
♦ Low line voltage delaying heat up.
Low Pres Message is displayed, fail indicator lights, and the program
is aborted if the pressure drops 4 psi (0.27 Bar) below the
required sterilization pressure.
Possible causes:
♦ Insufficient water in the chamber (see Low Water
message)
♦ A damaged heating element.
♦ A damaged pressure transducer.
High Pres. Message is displayed, fail indicator lights up, and the
program is aborted if the pressure rises 10 psi (0.6 Bar)
above the required sterilization pressure.
Possible causes:
♦ A damaged solid state relay.
♦ A damaged heating element.
Low Temp. Message is displayed, fail indicator lights and cycle is
aborted, if the temperature drops 2.5°C (4.5°F) below the
required sterilization temperature.
Possible causes:
♦ Insufficient water in the chamber (see Low water
message).
♦ Sterilization time has been set for too long a period.
♦ A bad temperature sensor.
High Temp. Message is displayed, fail indicator lights and program is
aborted if one of the following occurs:
♦ The temperature rises to 3°C (5°F) above the required
sterilization temperature during the sterilization stage.
♦ This message appears during the HEAT stage, if the
temperature sensor is damaged.
Possible causes:
♦ A damaged solid state relay.
♦ A damaged heating element.
♦ A damaged temperature sensor.
Low Water Message is displayed if during the Water Inlet stage
insufficient water enters the chamber. In units with water
pumps, the pump will try three times to fill the chamber
with water, if unsuccessful the cycle is aborted and the
message LOW WATER is displayed.
