EXPIRED MAINTENANCE
A video animation is available on https://video.wh.com/en_
global/dental-faq.
The sterilizer monitors the wear of consumables by counting the
number of cycles executed since the last replacement.
When the number of cycles is close to the maximum, a pre-alert
about the concerned consumable is displayed. Please check that
you have the requested spare part available, buy one if not. When
the maximum number of cycles has been met, a message to
replace the consumable will be displayed.

If you can not replace the consumable immediately, the sterilizer
will operate anyway but the message will appear again some cycles
later.
