wet, and liquid is overflowing from the
prime/soak trough:

the program does not exceed the
maximum well volume for the plate in
use.
• Adjust the dispense accuracy, see To
adjust dispense accuracy for a program on

• Remove any blockage in the prime/soak
trough.
If the overflow drain is completely dry:
• Check around the instrument for other
sources of leaks, such as the tubing
connectors from the bottles.
• If the leakage is coming from within the
instrument, contact Technical Support.
Note: A small amount of liquid will not
cause damage to the instrument. If the
trough is full, manually purge the trough
by touching Purge in the Options tab.
Carefully wipe up any spills under the
instrument.
