TROUBLESHOOTINGGUIDE
In the event of an error code, unplug the 3M™Attest™ Auto‑reader390G and plug it back in to initiate the self‑diagnostic test. If error code re‑occurs, call for repair orreplacement.
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 thefollowing:
Code/Issue Problem Solution
C1
Unit Warm‑upCaution
Incubation block not at temperature.
Allow a 30minute warm‑up after 3M™Attest™ Auto‑reader390G is plugged in. (Note: 3M™Attest™
Rapid Readout BI readings are disabled until incubator block reaches 37ºC +/‑ 2ºC).
C2
BI Removed from WellCaution
3M™Attest™ Rapid Readout BI has been removed before
incubation is complete.
Replace 3M™Attest™ Rapid Readout BI in proper well within 10seconds to prevent loss of collected
data.
C4 Ambient Light Caution Move 3M™Attest™ Auto‑reader390G to reduced ambient light conditions.
E1
Temperature ControlError
This error will occur if system is no longer able to control
the temperature of the incubator block (37ºC +/‑ 2ºC).
Unplug the unit and plug it back in to clearerror.
If error doesn’t clear, call for repair or replacement.
E3
MemoryError
3M™Attest™ Auto‑reader390G unable to save/read data
from memory.
Unplug the unit and plug it back in to clearerror.
If error doesn’t clear, call for repair or replacement.
E7
CommunicationsError
This error will occur if internal communications have failed.
Call for repair or replacement.
E8
LEDError
This error occurs for a specific well if the system detects
that a UV LED or Optics Detection circuit is not working.
Unplug the unit and plug it back in to clearerror.
If error doesn’t clear, call for repair or replacement. Do not use affected incubation well.
E11
BI Inserted IncorrectlyError
Incubation time remaining will not display and fluorescent
readings are not taken.
Ensure BI is designed to be incubated and read in the 3M™Attest™ Auto‑reader390G.
Ensure BI is fully inserted into incubation well.
E12
Power FailureError
Power to Auto‑reader was off for too long to provide valid
result for affected BI(s).
Ensure power supply connection to Auto‑reader is secure.
E14
Ambient Light Error (occupiedwell)
Fluorescent result will not display.
Rely on optional visual pH color change result for BI in affected well. Move 3M™Attest™
Auto‑reader390G to reduced ambient light conditions to avoid future occurrences.
Other Unwanted alarm sounds when positive BI detected. Disable alarm; refer to 3M™Attest™ Auto‑reader390G Configuration section for instructions.
Other
AlarmSounds
3M™Attest™ Rapid Readout Biological Indicator has been
removed from incubation/reader well prematurely.
Replace 3M™Attest™ Rapid Readout Biological Indicator in incubation/reader well within 10seconds

Negative ControlVial
BI not properly activated/ media did not contact spore strip.
Ensure BI cap is closed, and glass ampoule is crushed. Tap BI until media flows to and wets spore strip
at bottom of BI.
Other
Negative ControlVial
Control vial was sterilized.
Check process indicator on BI label. Use a non‑sterilized vial as a control.
Other
Unexplained PositiveBI
Adhesive residue on vial.
Do not place tape or labels onvial.
Other
