NOTE: To service your D25F Medicator you will need a strap
wrench (Part #TOOL01) and a small tip Phillips head screwdriver.
Step 1: If your Medicator is clicking, but not drawing 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
Medicator is clicking, unscrew and remove the suction hose nut.
Step 3: Then, remove the hose.

Questions and answers
As water flow is decreased clicking slows at a point clicking stops completely, flow still higher than minimum flow rating
If the Dosatron D25F stops clicking completely even when the water flow is above the minimum flow rating, possible causes include:
1. The piston inside the motor is stuck or damaged.
2. Internal seals or components are worn or blocked.
3. There is an obstruction in the water path preventing movement.
4. The unit may need cleaning or maintenance.
These issues can prevent the internal mechanism from cycling, which stops the clicking sound.
