PROBLEM
POSSIBLE CAUSE
PROPOSED SOLUTION
Excessive humidity on the material
and/or instruments at the end of the
program.
Excessive quantity of material inside the
sterilization chamber.
Check the quantity of material sterilized
and make sure that it does not exceed
the maximum allowed quantity,
depending on the type of load.
(See the
Summary Table
in
Appendix
Technical Characteristics”
).
material
not
correctly positioned.
position the material, and especially
wrapped material, according to the
instructions.
(See the
Chapter,
“
Preparing the
Material”
).
Wrong sterilization program selection
Select the appropriate sterilization
program for the type of material to be
treated.
(See the
Summary Table
in
Appendix
“
Programs
”).
Drain filter of the sterilization chamber
obstructed.
Clean or replace
the drain filter
(See
Appendix
“
Maintenance”
).
Traces of oxidation or spots on
instruments
quality of the instruments is
not
adequate.
Check the quality of the instruments
with the problem, checking whether the
material they are made of can tolerate
steam sterilization.
quality of the distilled water
not
adequate.
Empty the tank and fill it with high-
quality distilled water.
(See the
Water Supply Characteristics
in
Appendix
“
Technical
Characteristics”
).
organic or inorganic residues on the
instruments
Carefully clean the material before
subjecting it to the sterilization cycle.
(See the
Chapter,
“
Preparing the
Material”
).
Contact between instruments made of
different metals.
Separate instruments made of different
metals.
(See the
Chapter,
“
Preparing the
Material”
).
lime residue on the wall of the
sterilization chamber and/or accessories.
Clean the device and its parts, as
required.
(See
Appendix
“
Maintenance”
).
blackening of the instruments or
damage to the material.
Wrong sterilization program selection.
Check the adequacy of the sterilization
temperature of the selected program in
relation to the material to be treated.
