Remove BI and inspect to verify cap is fully closed, glass ampoule is crushed,
and growth media is in growth chamber. If necessary, repeat BI activation steps
and return BI to incubation well, ensuring it is seated properly.
Ensure power supply connection to Auto‑reader is secure. Retest sterilizer with
a new BI.

Unplug the unit and plug it back in. If problem persists call for repair
or replacement.
Ensure BI cap is closed and glass ampoule is crushed. Flick BI until media flows
to spore chamber at bottom of BI.
