In most cases alarms or errors are caused by lack of attention or lack of familiarity with
some technical and operational aspects. You will find below the list of some anomalies
with associated solutions.
12.1 The autoclave does not dry materials correctly
· Non-original trays, without holes or with different holes made of different material have
been used. It is advisable to use original trays only.
· Instruments have not been arranged correctly. (instructions of par.8.2)
12.2 The autoclave chamber has turned white
· Change immediately the type of water used, use exclusively demineralized or distilled
water, as indicated in the previous chapters and then clean the chamber.
· The whitish colour may be a consequence of the evaporation of organic materials from
the instruments. Instruments should undergo a more suitable and deeper cleaning.
12.3 The autoclave chamber hass bluish-green stains
· Instruments have not been cleaned correctly after the cleaning, rinse more carefully, if
the stains remain apply to the phone technical service.
12.4 The sterilization cycle interrupts without any patent reason
· Check whether the autoclave is connected to the power mains through extensions,
reducers or adapters, if so remove such accessories and connect the autoclave directly
to the power socket.
12.5 Stains on instruments
· Instruments get yellow due to the deposit of residual chemical fluid which has fixed on
the instruments due to heating. The rinsing was not suitable.
· The sterilization chamber has yellow stains. Some instruments with traces of chemical
fluid have been loaded into the chamber, such fluid has fixed due to heating. The rinsing
was not adequate.
· Instruments have whitish stains; the rinsing has been done with very limy water and the
instruments have not been carefully dried. For the final rinsing, we suggest the use of
demineralized water and a careful drying of the instruments
· Instruments have blackened since the material they are made of contain a high
percentage of carbon.
