We have found our VantageSE to be prone to problems with the solenoid
valves controlling the sheath and suction.  While these valves may not
actually fail, they can become so clogged that replacement is easier than
cleaning.  It sounds like your nozzle flush valve is not opening. I think
that is valve number 2 (I'm not in the lab to check). Open the panel with
the fluidics controls and either check the bank of LEDs to see which one
responds to the "Nozzle Flush" push button, or just trace the tubing.

If you don't have a service contract and want to try fixing the problem
yourself, try disconnecting the tubing to the valve top and bottom and
flush through with detergent using a large syringe (while the "Nozzle
Flush" button is pressed).  Don't get the electronics wet.
