Troubleshooting 9-11
9.2.4 Vacuum Error
Vacuum errors can occur if a reagent bottle is empty, the Wash Head is moved without going through
the on-screen prompts or one of the tubes inside the analyzer’s back door becomes disconnected.
1. Open the analyzer’s back door and look for any discon-
nected tubing and reconnect them.
In particular, check the
valves in the back door area as shown.
.
2. Make sure no reagent bottles are empty.
3. Press each valve button several times to determine if any are stuck. Buttons should easily
depress and pop back out. If a valve is stuck, contact Abaxis Technical Support.
4. Open the analyzer’s side door to see if any liquid has spilled on the floor of the analyzer. Wipe
up any liquid and power the analyzer off then on to re-home the needle. Run a blank to verify
that the issue is resolved.
5. If the issue persists, open the analyzer’s side door and look for any detached tubing. Dry and
reconnect if any are found.
6. Grasp the measuring tube (shown at right) and push it in firmly
while slightly rotating it to the right and left to be sure it is firmly
seated.
7. Run a sample or blank to see if the issue is resolved.
8. If the issue persists, contact Abaxis Technical Support.
Note: If the tube falls off again immediately when the sample or blank run is
attempted, the analyzer must be serviced: contact Abaxis Technical
Support.
