• The new fluid pump turns on and off sporadically during a service. What should I look for?
* In cooler line mode, this condition is normal.
1. If operating in a dipstick mode, test for proper operation of the shuttle valve system by removing
the shuttle valve and replacing it with an intermediate hose and extraction wand.
2. Add fluid to a test container or jug, using the ADD FLUID function. If pump runs steady in this
condition your shuttle valve should be replaced.
If sporadic operation persists, call Symtech Customer Support for troubleshooting instructions.
• The pump makes a groaning noise. Why?
This could be a sign of excessive restrictions in the filter or extraction wand screen. On rare occasions it
could also be an early sign of pump failure.
1. Service the filter on the rear of the unit.
2. Clean the screens on all extraction wands
3. Operate the unit to determine if the noise is still present. If the problem persists, call Symtech
Customer Support for troubleshooting instructions.
• The cooler line service won’t start when activated. Why not?
Vehicle must be running and maintain a minimum of 5-6 PSI of pressure to activate cooler line service
on key pad.
1. If there is less than 5-6 PSI of pressure present, please refer to the owner’s manual for
recommendations under “cooler line exchange” section.
2. Check both new and used fluid levels to make sure that there is enough fluid to perform the
exchange and that there is adequate room for the used fluid.
• The control panel behaves erratically (LEDs flicker, pumps won’t activate, etc.). What should I
do?
1. Remove the top and carefully inspect/repair all of the connections to the printed circuit control
board.
2. If problem persists, Call Symtech Customer Support for troubleshooting instructions.
• The displayed fluid levels drift with no fluid being added or removed. What should I do?
Call Symtech Customer Support for troubleshooting instructions.
• The unit is very slow when adding or removing fluid during a dipstick service. What could be
wrong?
Clogged primary filter screen, clogged extraction wand filter screen, faulty shuttle valve, failing used
fluid pump.
1. Clean the filter located at the rear of the unit under the cord wrap.
2. Clean extraction wand filter screen located in the fitting of the wand.
3. Test for proper operation of the shuttle valve system by removing the shuttle valve and replacing
it with an intermediate hose and clean extraction wand.

inserted.
