TROUBLESHOOTING GUIDE

In the event of an error code, unplug the 3M™ Attest™ Auto-reader 490 and plug it back in to initiate the self-diagnostic test. If error code re-occurs, call for repair or replacement.
The LCD Display panel will indicate detected malfunctions by displaying a caution or error code under affected BI wells. The audible alarm, if active, sounds and the LCD Display
backlight flashes to alert the user to all caution (except C1) and error codes. The alarm and backlight can be silenced and extinguished, respectively, by pressing the Buzzer Alarm OFF
button . Note that disabling the audible alarm does not disable the flashing LCD Display backlight. Refer to the following:

If error doesn't clear, call for repair or replacement. Do not use affected incubation well.
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.
Rely on optional visual pH color change result for BI in affected well. Move 3M™ Attest™ Auto-reader
490 to reduced ambient light conditions to avoid future occurrences. To clear E14 error code, after
visual pH color change result has been documented and BI has been removed, unplug the 3M™
Attest™ Auto-reader 490 and plug it back in.
Disable alarm, refer to 3M™ Attest™ Auto-reader 490 Configuration section for instructions.
Replace 3M™ Attest™ Biological Indicator in incubation/reader well within 10 seconds to prevent
loss of data collected.
Cycle power. 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.
Use a non-sterilized BI as a control.
Check process indicator on BI cap.
Do not place tape or labels on vial.
Place the vial so it does not come in direct contact with chemical indicators or tape.
On 3M™ Attest™ Auto-reader 490 Web App Configuration Page, go to Pushbutton Configuration and
