Symptoms
Causes and Comments
The buttons don’t work.
Some of the buttons are ignored during processing. If a button is not working consistently,
please contact Promega or your local Promega representative. Do not use spray cleaner on the
keypad, as it can seep in and short out the keyboard.
When I close (or open) the door,
the program does not advance.
There may be a problem with the door sensor. Please contact Promega or your local Promega
representative for service.
The machine runs but does not
advance to the “Run” screen.
A sensor for one of the heads may be failing, or a belt may be slipping. Please contact
Promega or your local Promega representative for service.
Poor sample quality, low yield
or low purity.
See the troubleshooting section of the Technical Manual supplied with your Maxwell
®
16
Purification Kit for more information.
Expected methods are not shown
on the LCD screen.
Verify the firmware setup. Refer to Section III.C.
Can I change the steps in a
protocol?
No. Contact Promega or your local Promega representative for firmware upgrades. As new
purification kits become available, new automated methods will be offered. Reagents are
predispensed and optimized to work with the preprogrammed automated methods.
VI.B. Power Failure
Power failure occurs during
instrument run.
To recover your samples after a power failure, first ensure that the particles are in one of the
wells of the cartridge and are not attached to the plunger. If the power failure occurred at a
point where the magnetic particles were captured on the outside of the plungers, manually
move the plungers up and down in the wells to wash off the particles. Then manually remove
the plungers from the instrument and restart the purification, from the beginning, with new
plungers.
