My enzymes are draining out of the reservoirs when the instrument is idle, what should I do?

For instruments with version 3.78 or newer software perform the following diagnostics routine:

 

1.
Run Line Charge routine two times with “All” selected with the flush tube assembly installed using deionized water.  This will prime the lines in the instrument.
2.
Set up Motor test with the Flush Tubes still connected.
 
a. Set all Supply Valves to Closed
b. Set Speed to 240 RPM
c. Leave Amount set to 10 ml
d. Press Start
3.
At the start of the routine, in the upper right corner of the screen you should see a number approximately 14.  Part way through the routine you should see it say “Plugged”.  This is normal for this stage of the test.
4.
Below the word “Plugged” you will see a set of numbers that will climb throughout the routine and should end in the range of 11 or higher.  Any number below 11 indicate a leaky valve.  In most cases, the valve causing the issue will be the buffer valve.
5.
Refer to Service Procedure TS-017 for maintenance instructions for the valve.  If the valve body is pitted, especially around the hole in the center, it will be necessary to replace the valve body using the TDF25.5 kit.  Follow Service Procedure TS046 for installation instructions.
