NOTE: To service your D25RE09 you will need a strap wrench
(Part #: TOOL01) and a Phillips head screwdriver.
Step 1: If your Dosatron is clicking but not drawing the
concentrate, it could be as simple as the strainer is plugged
with debris. Take a look at the strainer, if it's clogged just clean it.
Then, turn on the water and re-test your Dosatron unit.
Step 2: If the unit is still not drawing the concentrate, unscrew and
remove the hose nut and hose.
Step 3: Check to see if you feel suction on your finger.
