Possible Solution
Instruments made of inferior materials can be prone to discolouration.
Check the quality of the instruments that are spotting. Verify that they can
tolerate steam sterilization as per the instrument manufacturer's instructions
for use.
Instruments must be free of debris prior to sterilization. Clean and rinse all
instruments before loading them into the autoclave. Disinfectant residues
and solid debris may inhibit sterilization and damage the instruments and
the STATCLAVE. Lubricated instruments must be wiped thoroughly and any
excess lubricant should be removed before loading.
Separate instruments made of different metals.
See Section 5.3 Unwrapped Instruments for instructions on arranging
instruments made of different materials.
Ensure Stand-by chamber warming system is turned OFF.
(See Section 8.3 Setting the Stand-by Mode). Make sure the chamber is
cooled to room temperature before attempting a second Vacuum test. If
subsequent Vacuum tests consistently fail, contact your SciCan dealer.
Attempt a second Bowie-Dick test. If second Bowie-Dick test fails, contact
your SciCan dealer.
Remove load. Remove rack.
Use clean cloth or paper towel to mop up excess water.
Insert rack and load and start a new cycle.
See Section 5. Loading Instruments for details on load capacities.
Check the unit's serial number to see if it was accurately updated after a
logic board service. If number consists entirely of zeros, call SciCan.
Check for instrument or a cassette that is keeping the door from closing
correctly.
Check the door seal to make sure it is properly seated. To re-seat the door
seal, see Section 10.11 Replacing the Door Seal.
Leave the door open for 1 minute and try again.
Press the START button of the cycle you have selected to initiate the door
