NOTE: To service your D25RE2 you will need a strap wrench
(Part #: TOOL01) and a small tip Phillips head screwdriver.
Step 1: If your Injector 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 is clogged, clean it out and re-test your
Dosatron.
Step 2: If there is still no suction, turn the water on. If the unit is
clicking, unscrew and remove the suction hose nut.
Step 3: Then, remove the hose.
