Replace fuse (PN 46055), Replace the Vacuum
Pump Fuse on page 145
Repeated
blown fuses.
Vacuum Dissipate
Delay is set too low
for the volume of
the waste bottle.
See above. If not enough time is allowed for the
vacuum to dissipate, the pump will try to start
while it is under a vacuum. The pump draws
excessive current and blows the fuse.
Pump has been
flooded.
Remove the head from the pump and inspect it for
corrosion, crystalline buildup or liquid. Contact
BioTek TAC for information on pump rebuilding kits.
Fluid Aspiration
Problem
Possible Cause
What To Do
Poor or
uneven
aspiration.
Insufficient or no
vacuum.
Firmly seat the waste bottle covers. Ensure tubing is
connected properly. Check all external tubing and in-
line filter for kinks or clogs. If you are using an in-line
vacuum filter, it may need to be replaced.
With the vacuum pump on, remove the vacuum pump
tubing from the back of the instrument. Put your finger
over the port; if there is no vacuum, contact BioTek
TAC.
